CoastlinesThe geography of the UK coastline consists of avariety of natural features. These consist ofislands, bays, headlands and peninsulas.

The coastline of Great Britain is 11,073 miles(17,820 km). If the larger islands are added, thecoastline extends to 19,491 miles (31,368 km).

Nowhere in the UK is more than 70 miles (113 km) from the coast. It is estimated thataround 3 million people (out of 60 million) liveon the coast of the UK.

The total coastline of the Isle of Ireland is 1,980miles (3,170 km) of which the coast of NorthernIreland is 405 miles (650 km) in length.

The total length of the world’s coastline is in theregion of 217,490 miles, roughly equal to thedistance from the Earth to the Moon. It isestimated that thousands of miles of coastlineare eroded globally each year which can eitherlengthen or shorten the total length of coastlinemaking it impossible to be more accurate.

The sea plays an important part in our lives.Many people live by the coast, and most ofthe world’s largest cities are in coastal regions.

The sea provides us with energy (oil, gas, wavepower) as well as leisure activities, transportroutes, and food.

Storm damageSome of the best-loved beauty spots alongBritain’s coast suffered years’ worth ofdamage in the space of weeks or even hoursduring the winter storms.

The gale force winds and violent waves thatbattered the shorelines and have left parts ofwhite chalk cliffs crumbling, destroyed access tobeaches and the storms and high tides causedtwo years of erosion in just one afternoon.

Several metres of coast were lost in someareas, as thousands of tonnes of sand havebeen washed off beaches, exposingvulnerable foundations of seawalls.

Coastal protection byhard engineering Sea wallsWalls are made of rock, stone blocks or massconcrete, built at the base of a cliff or at therear of a beach and are used to protectagainst erosion or flooding. They are usuallyabout 3–5 metres high. Modern seawalls divertwave energy resulting in reduced turbulence.

Sea walls can cause sandy beaches todisappear, due to the stronger wavebackwash but are the second most traditionalmethod used in coastal management.

BreakwatersEnormous concrete blocks and natural bouldersare sunk offshore to alter wave direction and tofilter the energy of waves and tides. The wavesbreak further offshore and therefore reducetheir erosive power. This leads to wider beaches,which absorb the reduced wave energy,protecting cliff and settlements behind.

The precast reinforced concrete dolosse has replaced the use of concrete blocksbecause the dolosse being of interlockingdesign, is much more resistant to wave actionand requires less concrete to produce asuperior result.

Cliff stabilizationCliff stabilization can be accomplishedthrough drainage of excess rainwater,terracing, and planting, but these days rockanchoring and sprayed concrete is used tohold cliffs in place. This prevents landslides, clifferosion and other localized damage.

Harbour wallsRock or concrete walls are built to reinforce ariver estuary. The walls help to stabilise anddeepen the channel which benefits harbournavigation, flood management and riverbankerosion but can occasionally cause coastalerosion due to containment of longshore drift.

JettiesJetties, piers and other marine structuresconstructed in exposed locations requirecareful assessment of their hydraulic loads.Increasingly trade economics are leading tolarger ship sizes and existing and new portlocations for these vessels require longer jettiesin significantly deeper water.

In these instances construction of protectivebreakwaters becomes substantially moreexpensive, so in some cases jetties or theirapproach trestles are being constructed inexposed locations without breakwaterprotection.

TidesRepairs to shoreline structures have to take intoaccount the local tide patterns because thewindows available for work to progress are veryvariable. The designer and contractor need totake this account when pricing for a job.

Tides are the rise and fall of sea levels causedby the combined effects of the gravitationalforces exerted by the Moon and the Sun andthe rotation of the Earth.

The times and amplitude of the tides at aparticular location are influenced by thealignment of the Sun and Moon, by the patternof tides in the deep ocean and by the shapeof the coastline and near -shore bathymetry.

While tides are usually the largest source ofshort-term sea-level fluctuations, sea levels arealso subject to forces such as wind andbarometric pressure changes, resulting in stormsurges, especially in shallow seas and nearcoasts.

Tide tables are available for a wide variety oflocations in the UK and worldwide.

Wave actionIt is important to understand the basics ofwave action as this can have a significanteffect on the integrity and durability of marine structures.

The power of waves is one of the mostsignificant forces of coastal change. Wavesare created by wind blowing over the surfaceof the sea. As the wind blows over the sea,friction is created - producing a swell in thewater. The energy of the wind causes waterparticles to rotate inside the swell and thismoves the wave forward. The size and energyof a wave is influenced by the strength of thewind, how long the wind has been blowingand how far the wave has travelled.

Destructive waves are created in stormconditions. They occur when wave energy is high and the wave has travelled over a long fetch, has a stronger backwash thanswash and has a short wave length and is high and steep.

Destructive waves tend to erode the coast andcan structurally damage seawalls, jetties andother marine structures in a number of ways:

Hydraulic actionAir may become trapped in joints and cracksin cliffs and seawalls and when a wave breaks,the trapped air is compressed which weakensthe structure and causes erosion.

AbrasionFragments of rock and sand carried by thewaves grind down concrete and cliff surfaceslike sandpaper.

AttritionWaves smash rocks and pebbles on the shoreinto each other, and they break and becomesmoother.

SolutionAcids contained in sea water will dissolve sometypes of rock such as chalk or limestone.

SalinitySalt water is corrosive.

Salt water contains chloride and sulphate ions and a number of other ingredients thatcan attack concrete but it is the steelreinforcement in concrete structures or steel piles and columns in a pier or jetty thatcorrode in a marine environment.

Concrete contains cement which is alkalineand forms a thin passive film that protects the steel.

But if chloride ions are allowed to penetratethe concrete down to the steel, a corrosioncell could be initiated if there are anyweaknesses in the protective passive film. Thechlorides, being electrolytic, exacerbate thecorrosion process.

When steel corrodes, the rust expands in volumeand this will cause cracking along the steel andeventual spalling of the concrete cover.

Exposed steel corrodes quickly and can leadto dangerous structural failure.

1 Aggregate type: the aggregates should bedense, non-shrinking and alkali resistant.

2 Cement: Ordinary Portland cement withPFA or GGBS or sulphate resisting cementare used in marine concrete constructionand the minimum cement content ofconcrete is usually specified.

3 Water-cement (w/c) ratio: The water-cement ratio influences both the strengthand durability of concrete and even asmall increase of w/c ratio can increase theconcrete permeability greatly, as it controlsthe diffusion of aggressive salt-ions into theconcrete. Standards dictate a maximumw/c ratio of 0.45.

4 Influence of cracking: Reinforced concretestructures develop unavoidable cracksduring their service life as a result of initialand drying shrinkage, settlement andloading during normal service. Vibration,impact, flexure, stress reversal, torsion, andshear can all initiate cracks which will offer apath to the steel reinforcement for salt water.

5 Depth of cover to the reinforcement:The thickness of the concrete cover to thesteel is an important factor regarding rebarcorrosion in an aggressive environment. It affects the time taken for the salts topenetrate to the steel, and the subsequentrate of arrival of oxygen at the steel surfaceas in the case of permeability.

6 Diffusion of salts under pressure: The harmfulsalt ions can be absorbed into concrete atvarious depths under hydrostatic pressureand this can lead to weakening of theconcrete matrix, allowing chloride ions tocontact with steel.

7 Wetting and drying cycles: In a marineenvironment, the structural concrete in thetidal zone is subject to alternate wettingand drying due to tidal action and hence isat most risk of steel corrosion damage.

Disintegration of concrete and corrosion of reinforcement is the sign ofdeterioration of marine concrete structure. Many researchers have identified,after laboratory investigation and extensive studies on existing marine structures,a number of factors affecting the deterioration of reinforced concrete in such anaggressive environment. Some of these important parameters are stated below:

1312



Requirements for marineinfrastructure repairsCorrosion of reinforcing bars induced bychloride ion ingress is a major cause ofdamage in marine environments.

Reinforcement corrosion causes a reduction in the service life of reinforced concretestructures, therefore a regular schedule formaintenance and repair is of fundamentalimportance in ensuring safe and efficient useof a structure.

Structural surveysA detailed investigation to determine theextent and cause of degradation requires tobe carried out by an experienced corrosionengineering practice. Only then an assessmentof corrosion damage can lead to the selectionof effective repair schemes.

BS EN 1504 “Products and systems for theprotection and repair of concrete structures-Part 9: General principles for the use ofproducts and systems” outlines in Clause 4.3the necessary steps to be taken in carrying outan assessment of the defects in the concretestructure, their causes, and of the ability of theconcrete structure to perform its function.

This takes into account the following :

a) the visible condition of the existingconcrete structure;

b) testing to determine the condition of theconcrete and reinforcing steel;

c) the original design approach;

d) the environment, including exposure tocontamination;

e) the history of the concrete structure,including environmental exposure;

f) the conditions of use, (e.g. loading or other actions);

g) requirements for future use.

Clause 5.2 presents the various options thatcan be considered:

a) do nothing for a certain time but keepmonitoring the structure;

b) re-analyse the structural capacity, possiblyleading to downgrading in function;

c) prevent or reduce further deterioration;

d) strengthen or repair and protect all or partof the concrete structure;

e) reconstruct or replace all or part of theconcrete structure;

f) demolish all or part of the concretestructure.

Clause 6 specifies the basic principles whichshall be used, separately or in combination, to protect or repair concrete structures. Theprinciples of protection and repair are basedon chemical, electrochemical or physicalprinciples that can be used to prevent orstabilise the deterioration of concrete orelectrochemical corrosion on the steel surface,or to strengthen the concrete structure.

Principles 1 to 6 cover defects in the concreteor concrete structures that may be caused by mechanical: e.g. impact, overloading,movement , chemical and biological: e.g. sulphate attack, alkali aggregate reaction and physical: e.g. freeze-thaw action, thermal cracking, moisture movement,salt crystallization and erosion.

Marine structures are mainly subject toreinforcement corrosion which is covered byPrinciples 7 to 11. Corrosion caused by theingress of chloride ions is more difficult to treatthan corrosion caused by carbonation.

Treatment of local areas of concrete that arecontaminated by chloride ion can besuccessfully carried out by patch repair thatremoves all the contaminated concrete.However, where contamination is extensive,treatment of areas of damage alone will notprovide a lasting repair solution. Areas repairedwith new mortar or concrete can initiatecorrosion in adjacent areas of contaminatedconcrete (often termed incipient anode or ring anode effect). In these situations,additional methods will need to be consideredif corrosion is to be arrested, such as thosegiven in Principles 7 to 11 (See over page).

Protection of the structure

1514



BS EN 1504 Principle 10 is concerned withcathodic protection of the concrete structure.This is appropriate where chloride contaminationis significant or carbonation has reached thereinforcement resulting in a high risk of corrosion.

Impressed current cathodic protection applied in accordance to BS EN 12696 cancontrol corrosion, counteract the incipientanode effect and can limit the amount ofconcrete removal.

Regular inspections after repair work arenecessary to ensure satisfactory performanceof repair systems. In addition, fieldinvestigations of repaired concrete structuresare necessary to develop guidelines for the

adequate selection of concrete repairsystems, improved repair procedures,extended durability of rehabilitated structuresand evaluation of discrepancies betweenlaboratory results and field performance.

BS EN 1504 Standard provides the user with eleven principles of concrete repairand protection to be used for concrete repair.

Where contamination of the concrete isextensive, but it is not possible to remove allcontaminated concrete, incipient anodeformation can be controlled by treating thesurface of the reinforcement in the patchrepair to prevent corrosion. Coatings can beapplied directly to the reinforcement where itis exposed as part of concrete restoration.These coatings can contain active pigments,which may function as anodic inhibitors or bysacrificial galvanic action.

Other types of coatings can form barriers onthe surface of the reinforcement. This methodcan only be effective if the reinforcement isprepared to be free of corrosion and thecoating is complete (i.e. the bar must becompletely encapsulated and the coating isdefect-free). The method should not beconsidered unless the whole of thecircumference of the reinforcing bar can becoated. The effect of the coating on bondbetween the reinforcement and concreteshould also be considered.

Alternatively, corrosion inhibitors can be usedthat chemically change the surface of thesteel or form a passive film over it. Corrosioninhibitors can be introduced either by additionto the concrete repair product or system, or byapplication to the concrete surface followedby migration to the depth of the reinforcement.

Inhibitors that are applied to the surface of theconcrete must penetrate the concrete downto the level of the reinforcement to takeeffect. There is currently no standard forinhibitors, so evidence of the effectiveness ofany such product should be obtained beforespecifying its use.

Note that some corrosion inhibitors work by control of both anodic and cathodic areas. An example of this is the ambiodicweber.tec guard MCI.

Product selectionProducts used for remediation of marinestructures should comply with the requirementsof BS EN 1504 Parts 2 to 7 and in accordancewith EU directives and should be CE markedwhere appropriate.

In order to be suitable for use in marine tidalsituations, certain products should be rapidsetting and should be able to resist the ingressof chloride ions at early stages of their strengthdevelopment.

In some cases, consideration should be givento applying thicker sections of new concretecover as sacrificial layers to arrest the progressof chloride ion penetration to the steelreinforcement.

Cathodic protection is especially appropriatewhere chloride contamination is significant, orcarbonation to the depth of the reinforcementis extensive, resulting in a high risk of corrosionof reinforcement.

Impressed current cathodic protection appliedaccording to BS EN 12696 can control corrosionregardless of the level of chloride contaminationin the concrete and limits the amount ofconcrete removal to that physically damagedby corrosion of underlying reinforcement. Its longterm effectiveness depends on adequatemonitoring and maintenance.

Cathodic protection is effective for achievinglong-term corrosion control and counteractsthe incipient anode problem and the effect ofconcrete contamination (see BS EN 12696).

There are many different types of anodesystems used in cathodic protection, some ofwhich use an impressed current from anexternal power source, while others usegalvanic (sacrificial anode) action.

Recent developments include a hybrid anodesystem based on the use of a sacrificial metalin both an impressed current and sacrificialanode role where an impressed current isdriven from the anode to the steel using atemporary power supply.

Contractor: Jackson Civil Engineering

Applicator: Currall Lewis & Martin (Construction) Limited

In the refurbishment of Chertsey Lock, on the River Thames, Weber supplied highspecification weber.cem spray DS structuralrepair concrete.

After removal of the concrete, resin injectionworks to 200 linear metres of cracked walls was carried out. The freshly sprayed walls weredragged back with a feather edge rule tolevel the material and lightly sprayed with

water after the initial set of around one hour, to provide a good surface for the final pass of30-40mm of weber.cem spray DS. A furtherprocess of levelling was required beforesealing the surface to the specified finish.

weber.cem spray DS has been especiallydesigned for dry process spray application togive high early strength in 2 – 3 hours, reducedrebound and maximum application thickness.

Kingston Wharf, one of many jetties on thebanks of the River Medina estuary in Cowes,was built in the 1950’s and is of reinforcedconcrete construction. It has been used fordelivery of fuels to the nearby power stationand to the island. The jetty was suffering fromdeterioration of the reinforced concretestructure due to marine salt corrosion of thesteel. The contractor had to overcomeproblems with poor condition of the structureand consequent sequencing of breakout andrepairs. Defective areas on concrete wereremoved by ultra-high pressure water jetting

which also cleaned the corroded steel. Thevolume of defective concrete was found to bemuch higher than estimated from initialsurveys. A cathodic protection system usingPatchguard anodes from CPT were used toprotect the steel reinforcement with theanodes fixed into the soffits and beams. Over60 tonnes of weber.cem spray DS, a Class R4concrete to BS EN 1504:3 was used to repairand reinstate the concrete structure.weber.cem pyratop, a rapid setting Class R4concrete for external paving, was used torepair concrete roadways and ramps.

The Braefoot Marine Terminal consists of twojetties, located on the north shore north ofIncholm Island. Products produced at theMossmoran Plant in Fife are exported at theBraefoot Marine Terminal. The jetty wassuffering from deterioration of the reinforcedconcrete structure due to marine salt corrosionof the steel. The contractor had to overcomeproblems with rising tides and consequentsequencing of breakout and repairs.

Recommendations for the repairs wereprovided by Weber who supplied specialistproducts and gave technical support duringthe repair phase of the contract. An innovativecathodic protection system using hybridDuoguard anodes from CPT was used toprotect the steel reinforcement with theanodes fixed into the soffits. weber.cem HB40mortar was used to fill the cable chases.

Client: Barcelona Port Authority, El Prat de Llobregat (Barcelona)

Grouting Contractor: Gantrex (Espana), Gantrex (Belgium), Gantrex (UK)

A new container wharf at the port ofBarcelona required a new crane rail system tobe installed. The rails were about 960m inlength with 400mm and 600mm widecontinuous soleplates. Other rails weredesigned to have discrete bearing plates.

The grouting application used a feed-hopperand the mixed grout was poured into thehopper with a good level of grout maintainedto ensure a good smooth flow of the groutunder the soleplates.

The ambient air temperature was around30OC so the mixed grout flowed very freelyinto the 50mm gap under and across thesoleplates. The grout was also used to anchorthe holding-down bolts to a depth of 300mm.

The sea-wall fortification of the Outer Bight offerscritical protection to the navigation channel ofNewhaven Harbour. Recent storms havecaused damage to concrete with weak surfaceareas being eroded and substantial lateral andvertical cracks being opened to further waveand water damage. Fissures up to 500mm deep,running for several metres along the wall face,have had to be repaired to avoid the realpossibility of a major breach of the defences.

Nearly 500 tonnes of Weber’s sprayedconcretes was used to repair and reinstate theconcrete structure. weber.cem spray RS, theultra-rapid setting version of the popularweber.cem spray DS was used to seal thefissures during high tides and then to provide adurable skin over the steel mesh that was fixedto the existing concrete wall. Both concretesare Class R4 to BS EN 1504 : part 3

Products: weber.cem spray DS, weber.cem spray RS andweber.cem conspray

Client: Torbay Council

Contractor: Millennium Marine Contractors Ltd,Newton Abbott, Devon

Consulting Engineers: CASE Consultants, Torquay, South Devon

The reason for the repair was an already failingrevetment made worse by the winter storms of2013. The revetment protects the toe of theseawall and the highway behind housing theunderground utilities. Over 10,000 tonnes of sandwere washed out to sea during the storms. Thisexposed the seawall by as much as 3 metresand many defects were found below the usualsand level, the most significant was the damageto the seawall foundations/revetment.

This required infilling with mass concrete suppliedby ready mixed trucks.

weber.cem spray DS sprayed Class R4 concretewas used to re-profile the revetment to a depthof around 250mm. In some cases, water from thecliffs beyond was weeping through cracks in thewalls and the rapid setting weber.cem spray RSClass 4 concrete was then used to seal theleaks and build up a new protective cover.

The jetty was suffering from deterioration of thereinforced concrete structure due to marine saltcorrosion of the steel. Previous attempts at repairfailed due to access difficulties but the contractorovercame these problems and was rewarded withthe Construction News Concrete Specialist of theyear award 2014. Recommendations for the repairwere provided by Weber who supplied specialistproducts and gave technical support during therepair phase of the contract. An impressed current CP system was used to protect the steelreinforcement with sacrificial anodes fixed into the soffits to provide additional protection.

Hydro-demolition was used to breakout thespalled and cracked concrete, to wash outsurface chlorides and to clean the corrodedsteel reinforcement.

weber.cem spray DS, a Class R4 concrete to BSEN 1504 : part3 was used as an overlay to theimpressed current CP system, to build up a newprotective cover and for repairs to the structure torequired profiles and weber.cem spray CP (ClassR4 to BS EN 1504 : part3) was used to embed thesacrificial anodes and for small patch repairswhere a more conductive mortar was required.

Many of the concrete beams were in a poorcondition due to corrosion of the bottomreinforcement. In some cases, the covercretehad spalled and fallen off. The cutting out andpreparation was done by hydro-demolition.The steel which appeared to be badlycorroded showed up as fully functional afterblasting and cleaning.

Replacement of the concrete was achievedby the concrete spray technique usingweber.cem spray DS and in places subject toearly tidal action, weber.cem spray RS therapid setting version. weber.tec guard MCI wasapplied on the soffits between the beams tomitigate further corrosion.

The jetty was built in 1979 of RC construction,but was badly damaged by corrosion of thesteel reinforcement. Results of the survey andtesting indicated that the depth of chloridecontamination was up to 80 mm into theconcrete, which meant ineffective cover,therefore severe corrosion of the mainreinforcement. The problem was worse on pilecaps carrying the structure. The cutting out andpreparation was done by hydro-demolition. Thesteel which appeared to be badly corroded

showed up as fully functional after blasting andcleaning. Replacement of the concrete wasdone by the concrete spray technique usingweber.cem spray DS and in places subject toearly tidal action, weber.cem spray RS the rapidsetting version which was used on the pile capsand the standard DS was used for sectionsoutside the tidal zone. weber.tec aquapel WRwas applied on the soffits between the beamsto limit absorption of seawater.
