Our Role in the Piling Market

ROMTECH is the UKs premier supplier of pile reinforcement.

This includes:

Factory manufactured pile cages to BS 7123

Cage Former Systems for the rapid, accurate site steelfixing optionto UK CARES Technical Approval Document TA5/5010 : 2005

Loose rebar, rings and helical to BS 4449:2005

LOLER Compliant offload / stillage system to avoidworking at height on the trailer deck.

Safe Splice Safety orientated Pile Cage fasteningsystem for the Rotary Piling Technique

All factory prefabricated pile cages conform to UK CARES AssessmentSchedule 10 by which we mean that we design the fillet welds between bandsand cage rebars to give an acceptable factor of safety for cage lif ting andinstallation. We inspect finished cages in order to ensure cage complianceagainst this temporary works design.

All factory tackwelds comply with UK CARES Assessment Schedule 6ensuring against rebar embrittlement so reducing site liability during piletrimming.

ROMTECH produces CAD drawings of rebar cages prior to contractsstarting. This enables prior approval of the actual cage to be used, as well as

being a works instruction, a site inspection instruction and finally an as-builtrecord of the steel components within the pile.

We at ROMTECH are used to working between the late arrival of designinformation and the unremitting deadline of imminent c age delivery.

Whichever ROMTECH product option is selected, our aims are to ensureproduct compliance with the latest Health and Safety Legislation, high siteproductivity and freedom fr om metallurgical defects; the whole packagepresenting itself as a cost-effective solution.

Should future sites demand solutions which are beyond the scope of ourexisting product lines, then we would work with site to either modify theseor develop fresh solutions. We regularly attend sites and carry out toolboxtalks to personnel and compile Method Statements in order to ensure correctproduct usage.

Finally, ROMTECH is well-versed and experienced at operating within such ademanding environment. We offer one-stop shopping for all your existing pilereinforcement needs along with a unique service to develop new product linesand so meet the challenges of the future.

ROMTECHs AutoCad Detailing Facility Routinely:

Defines the exact cage format by producing a working drawing using customer contract documents. This usually takes place a

few days prior to delivery of the relevant cage type and enables all parties to progress forward from the original contract rebar

drawing/schedule stage.

The drawing will cover the scheduled main and transverse reinforcing bars and cage dimensions but can also include lifting

points, skid spacer locations, debonding isofoam, sonic coring/inclinometer pipes and couplers. Where clamped cage

formers are used, the drawing will state the recommended torque setting.

Notes

Table is for guidance only.

Key: Not Possible Helicals Not Recommended

Helicals

ROMTECH can make helicals from R6 to H12 for cage O/D up to 1050mm and in

H16 for larger cage O/Ds as indicated by:

ROMTECH can make helicals of O/D ranging from 100mm to 2000mm.

The range shown can be pulled out to pitch on site.

Helicals can be made to pitch for smaller O/D but rings should preferably be specified.Where helicals are made to pitch, steelfixers recommend that the overall axial length should not exceed 1.5m 2.0m.

Helicals made to pitch will incur an extra charge per tonne production cost over ROMTECHs normal selling price.

It should be noted that helicals made to pitch are extremely bulky and are likely to incur extra carriage costs.

Rings

Rings should be specified for smaller O/Ds rather than helicals. ROMTECH can make rings in bar sizes 6mm to 25mm.

ROMTECH can make rings in O/D size from 100mm to 3000mm.

Rings can be made overlapped or welded.

When ordering overlapped rings, the lap is generally defined as 40 x dia. of the bar specified.

Welded rings will generally have a lap of 50mm unless specified otherwise. Note: lap may need a structural weld.

When ordering closed pitch helicals, please state the wire size, finished O/D, Number of turns & pitch of helical when pulled open.

ROMTECH will calculate the O/D size of helical to allow for shrinkage, to finish up with your final O/D when pulled out to pitch.

Clamped Cage Former Systemfor Site-Assembly

This system is a scientifically safe means of site assembling pile cages where an alternative to traditional site welding

is required. (certified to UK CARES technical approval document TA5/5010:2005)

Cage formers contain rebar locator stubs to ensure highly accurate circumferential settings to main cage bars

Twin-ring construction gives rigid box-like nature to cage formers ensuring robustness of finished pile cage

Integral mechanical clamps, when torqued at 80Nm, provide scientific cage lifting points (typical single clamp test strength= 120kN) giving high factors of safety during suspension of cage

Built-in anti-racking supports permit cage stability during site lifting operation

Rigid, integral cover spacers supplied to any cover dimension reduce workload of piling crew

Five grades of spacer footprint available according to cage weight and piling application

All ROMTECH skid spacers comply with the heavy-duty structural test requirements of BS 7973:2001

Template-like nature of formers allow rapid, highly accurate cage steelfixing operation

Clamp test strengths available on request

Economic cogency of cage former solution enhanced by supplementary locator rings and ladder spacers

Effective Temporary-WorksSupport of Cage Within Pile Bore

PilingPiling Accessories

Mobilises soil bearing capacity to provide massive toe-support to heavy pile cages during installation

Prevents cage dropping during installation or casing-extraction so avoiding the liabilities of low cages and the unscheduled

need for expensive repair couplers

Simple, scientific, torque-controlled integral clamps are rapid and easy to work with, so avoiding the need to site-weld the

feet to the cage whilst making the feet secure

Use of integral clamp allows feet to be detached from previously fitted-out cages in order to telescope the foot to alter itsprojection below the cage to allow for changing toe bearing

Projection of cage foot through bottom-end concrete of pile has been deemed acceptably durable on CTRL projects,Terminal 5 Heathrow and other prestigious contracts due to the anaerobic nature of the environment at the base of the pile

GeotechnicalIntroduction



GeotechnicalGround Anchors

Ground Anchors and Piles can be used to provide Global

Stability in an Earthworks structure. They (unlike Soil Nails)

are actively loaded from the onset. Temporary uses include

tie backs to sheet piles, and temporary works stabilisation of

open excavations during contract period.

Installed on a grillage, lightly-loaded, with a short shank

length and without pre-tensioning. Hollow self drill option

is quick and easy to install (drill, flush and grout in one

operation). Harder drill bit (eg. Tungsten Carbide Button Bits)

are also available. The product is also suitable for connecting

friable surface material to hard substrate.

Ground Anchors Rock Bolting

Stabilises existing structures through

underpinning where installation access (bothhorizontal and vertical) is limited. Principle is

that of single central bar and ability to couple

this. Other applications include the upgradingof strip footings, stanchion bases and Network

Rail power gantry bases.

Micro Piling

Stabilise shallow depth ex-foliated rockface

by tying back to the stable rock above, inpreparation work for N.A.T.M. technique.

Hollow bar format provides conduit for

grouting. Exposed ends can be used to bolt onand support further reinforcement layers.

GeotechnicalSelf - Drill Hollow Bar - Key Dimensions & DesignData

Hollow Bar Technical Data

Typical Thread Bar Couplers &Termination Accessories

Typical Hollow Thread Bar

ROMTECHs Hollow Bar system is a continuously threaded left handed steel bar which can be drilled and grouted into loose,

unstable and collapsing ground. The steel is a hollow configuration to allow for simultaneous drilling and grouting, a technique

designed for eliminating the need for pre-casing, therefore increasing the installation rate.

Produced from hollow steel tubular raw material, the bar is cold rolled into a standard ISO rope thread during which the

formation of steel is enhanced, providing the yield strength. The rope thread provides an appropriate surface between the bar

and the grout, therefore enabling a strong, resilient bond to be created.

ROMTECH Self Drill Hollow Bar provides effective solutions for rock bolting, ground anchoring, micro piling, soil nailing and

spiles applications.

Tie backs

Due to the high variety of steel qualities and diameters, our

threadbar system can fulfil the requirements of the different tierod construction designs in an optimal way. Main applications

of tie rods are bracing for embankments, sheet-pile, shed-roof

and frame structures, as well as tie back retaining walls.

Pre-stressed Soil and Rock Anchors

Anchors are elements which introduce compression forces intothe ground through tension members. For this, the anchorage

head conducts the forces into the grouted body, which

transfers the load safely into the surrounding material.

Main areas of applications of Pre-stressed soil and rock

anchors are slopes, embankments, excavations as well as

cavern and tunnel construction.

Post Tensioning SystemThere has been a continuous development of the threadbar

product into the various post tensioning applications inherentin glued, segmental bridge construction. Such techniques

using various methods of cantilevering and incremental

launching rely on the post tensioning bars for the longitudinal

and transverse connection of segments both in the temporary

and permanent sense.

The ease of installing and stressing threadbar lends itself to

applying a triaxial stress field to the concrete. This, as a means

of crack control makes threadbar a prime candidate for

marine applications.

ROM ShearLadder SystemApplications

In general the RT550 and RT800 are ideal for soil nailing applicationsbecause they have an excellent range of accessories and the most

beneficial yield properties.

RT1050 is widely regarded as the best grade for post-tensioning andother applications where exceptional tensile strength coupled with good

elasticity is required.

Other grades have various properties which make them ideal for general

reinforcement and formwork ties.

Storage instructions

Care should be taken at all times to ensure that the units are

not damaged either by bending or mishandling

Storage of the nails and components should be in a properly

covered and protected areaThe manufactured components should be stored

horizontally at all times

Finished units should never be stacked, but should be properly

supported on timber racks to ensure they do not deflect

Handling and site transport

Care should be taken when transporting the nails to the

fabrication yard and from the yard to the borehole. The nails

should be adequately supported (bracing or support at a

maximum distance of 1.5 - 3.0m depending on diameter of

bar) so as not to damage the pre-grouting.

To avoid bending the bar by lifting it, check carefully and if

necessary, reduce distance of support.

During transport, the nails should be laid flat on suitable

transport and with supports between the layers of nails.

Care should be taken not to knock the nails so as to avoid

the pre-grouting cracking.

The nails can be lifted and transported by crane with a brace

of lifting device on the air-sided end of the bar (ring nut etc.).

Take care that by lifting the bar does not bend and the enddoes not slip on the ground.

Prefabrication Beamform Permanent Formwork Clay Heave Protection

Thermaflor Accessories



GroundworksPrefabrication

ROMTECH Groundworks offer a complete off site CARES Approved(steel & welding Appendix 6) prefabrication service on

All cages are labelled for ease of identification, and are supplied with a layout drawing for accuracy and speed of placement.

Splice bars are loose-tied inside the relevant cage

Prefabrication offers a reduction in the need for skilled labour, which can lead to a reduction in programme, a reduction in

waste caused by unforced errors, and an improvement in site Health and Safety.

A key benefit of ROMTECH prefabrication is that semi - skilled site operatives are able to instal l cages in a few hours ratherthan the normal 1-2 days of the loose rebar option.

Deliveries can be phased to an agreed programme: this being particularly useful in tight or restricted sites. Colour coded

labels can be factory fitted for easy site identification of delivered components.

Using customers General Arrangement (GA) and Reinforced Concrete (RC) drawings and

schedules, we identify the opportunities for rebar prefabrication where appropriate. By

liaising with The Engineer, we are able to provide alternative solutions which offer commercial

cogency in terms of programme and site productivity. In addition, fewer prefabricatedcomponents of known weight & size, mean fewer, better organised site operations, leading to

significant benefits in site Health and Safety.

Such objectives are achieved for groundbeams by detailing for maximum prefab cage length

with a minimum of loose rebar cage to cage connections. The provision of factory welded

skid spacers provides soffit support to beam cages off the blinding and avoids the site fittingof separate spacer units. The colour coding of prefab beam elements, as depicted on theROMTECH layout plan, offers the possibility of rapid, accurate site - installation. In addition,

the LOLER - compliant cage offload system allows the consignment to be removed without

the need to climb onto the vehicle deck.

ROMTECH Shear Ladders avoid the usual sausage link detail which requires loose rebar

upper and lower reinforcement layers in two way spanning suspended slabs. This producttherefore permits the use of heavy prefabricated mesh layers above and below while

furnishing both an adequate punching shear resistance in the finished slab and an effective

means of spacing upper and lower mesh around the column head.

In the case of retaining walls and suspended slabs, ROMTECH can offer the options of

various bar diameters and centres, staggered bar locations and flying ends within itsindividual prefabricated mesh or mattress units. The main site benefits of these features are

a reduced site installation period, an alleviation of congestion at laps and a reduction of the

working at height element.

GroundworksBeamform

Developed in the mid nineties by Construction professionals, Beamform is manufactured from high density expanded polystyrenewhich ensures robustness for back filling purposes. In excess of one million units have been successfully installed to date.

This simple, one component system, is an ideal solution for numerous formwork applications and utilises unskilled labour with

no specialist plant requirements.

Beamform is ideally suited for use with ROMTECH prefabricated cages and offers significant time savings on construction

program cycles, with minimum waste, when compared to traditional methods and other sacrificial systems.

Available Ex-stock, delivered to site palletised, Beamform is supplied in heights ranging from 350mm to 750mm in 50mm

increments and may be stacked where depths of pilecaps or beams exceed the maximum unit height.

Beamform by nature is light but strong, allowing easy positioning by one unskilled person, who will be able to install in excess

of 250m per day, safely and quickly. The correct installation is helped by the tongue/grooved ends for the self location of

adjacent units; this complying with Best Practice Guidelines relating to formwork.Formwork must have a continuous line and shape before, during and after the concrete pour

The inherent strength of Beamform allows the excavated material from site to be reinstated as backfill, rather than importing

material at an additional cost.

Since Beamform is installed after the reinforcement, specified cover is achieved by the use of Grippa Plate Spacers

which clip on to the links. Once backfilled safe, unimpeded access for all other trades working on site results. The speed ofinstallation ensures that open trenches, subject to adverse weather conditions become a thing of the past.

Although initially being designed for use below ground on sites with ring beams and pile caps, the versatility of Beamform has

meant that users have enjoyed the same benefits above ground, on toe beam rafts, pad foundations, stepped footings, radius

beams, unreinforced foundations (to save otherwise wasted concrete) and reinforced concrete slabs.
