Road.
Contamination of the road foundation by underlying subsoil material reduces the load bearing capacity and/or
drainage characteristics of the granular fill material.
Bontec SG woven and N nonwoven geote!tiles offer an effective solution to this problem through the
provision of a bespo"e separation layer. Bontec offers high mechanical performance per unit weight and so
ma!imi#e their resistance to installation damage and ensure a long term in$situ performance.
%s road foundation materials continue to get increasingly e!pensive& then the 'udicious use of an appropriate
geote!tile can often reduce foundation design thic"nesses by a substantial margin. Rutting depth is limited by the
geote!tile reinforcement& which acts both as a (sounding board) during fill compaction& and as a highly effective
separation layer. *his use of typically SG +eavyweight geote!tiles& can produce significant savings in foundation

Railway.
*he pumping action generated by the passing of railway traffic over the trac" can cause the rapid deterioration of
the ballast and the brea"down of the granular support given by the ballast to the sleepers.
n these applications +eavyweight N geote!tiles have many years of proven performance as a
filtration/separation layer to help reduce trac" failure from pumping.
nstalled between the ballast and underlying soil& the "ey properties of the geote!tile include good puncture
resistance and a small characteristic opening si#e.

Retaining alls.
*raditional soil stabili#ation methods involving the construction of steep emban"ments or vertical retaining walls
sometimes prove to be an e!pensive solution. Bontec +ighStrength geote!tiles now offer a new cost effective
construction option.
*hrough their outstanding tensile strength& high modulus of elasticity& low creep and e!cellent resistance to
ultraviolet radiation& reinforcing geosynthetics offer one of the best guarantees of a durable and reliable
construction.
=uring emban"ment construction over wea" impervious soils& e!cess pore water pressures fre>uently develop
and may lead to the formation of slip planes.
%lternatively +S geote!tiles can provide a cost$saving method through the provision of a basal reinforcement
layer that prevents the formation of slip planes and restricts the deformation of the emban"ment until such time
as the foundation soil itself gains ade>uate stability.

=rainage.
?!cess groundwater must be carefully controlled both during and after construction in order to ensure structural
stability. *ypical drainage systems include carriageway edge drains to protect the roadway& bac" of wall drainage
to reduce hydrostatic pressure on the rear face of wall& or possibly a drainage mattress to provide the rapid
escape of surplus water from the base of an artificial sports surface.
n these applications lightweight N @ SN nonwoven geote!tiles and +, woven geote!tiles offering high water
permeability and superior filtration characteristics provide the ideal filter layer for enclosing the drainage media.
By designing the hydraulic properties of the geote!tile to the surrounding soil& the geote!tile surface will provide
a stable platform for the development of a natural soil filter and subse>uent long lasting filtration performance.
