Geotextiles

Geotextiles are permeable fabrics which, when used in association with soil, have the ability to separate, filter, reinforce, protect, or drain.
Applications
Geotextiles and related products have many applications and currently support many civil engineering applications including roads, airfields, railroads, embankments, retaining structures, reservoirs, canals, dams, bank protection, coastal engineering and construction site silt fences.

Standard filter/separators (general construction, highways)
Standard Grades 700/900/1000/1300/1500/2000/3000/4000/4500 with composition 70% polypropylene / 30% polyethylene,
Tensile strength and elongation to ISO 10319, CBR Puncture Resistance to ISO 12236 & Dynamic Cone Puncture to ISO 13433

These geotextiles enhance the performance and design life of granular layers by providing the filtration and separation functions. Typical uses for these standard geotextiles include ground stabilisation (between the sub-base and subgrade) and around drainage materials.

Preventing intermixing of granular materials and soils

Our geotextiles provide an effective solution to the problem of constructing a stable granular layer over soft foundation soils. When stone is placed directly on a soft subgrade, the imposed load often causes intermixing of two layers. This results in contamination of the stone layer and a resulting loss in bearing strength, surface rutting and deformation at the sub-base/subgrade interface.
Preventing the ingress of fines into drainage media

Whether it's a granular drain or a geosynthetic alternative such as open geocellular units, our standard geotextiles are ideal for preventing the ingress of fines.

These filters/separators are used extensively in the construction of:

Paved and unpaved roads
Railways
Car parks and hardstandings
Cycleways and footpaths
SuDS installations
Green roofs

Durabilitty
The products are predicted to be durable for more than 25 years for non reinforcing applications, in soils with a range of pH 2-14 and soil temperatures less than 25 degrees C.

Chemical Resistance
Alkali - Resistant to all naturally occurring soil alkalis.
Acid - Resistant to all naturally occurring soil acids, (soils with pH 1-14).

Biological Resistance
The material is unaffected by bacteria, fungi, etc. Since it is not a source of nourishment, rats and termites will not eat the product as food.

Geotextile Sigma 100

Sigma 100 geosynthetic geotextile is a non woven thermally bonded permeable geotextile fabric ideal for construction and civil engineering applications. Manufactured from PE/PP, the BGT100 geotextile delivers a high performance solution to a large range of applications including Separation, Filtration, Drainage, Erosion control and ground stabilisation.

Sigma 100 geotextile is resistant to all naturally occurring soil acids and alkalis and is unaffected by biological contaminants such as bacteria or fungi.

Geotextile is important to use in paving construction particularly for installations involving porous ground reinforcement paving grids - for grass or gravel surfaces in applications including car parks or access roads / paths. The Sigma 100 geotextile allows full water penetration whilst separating fine material (soil / sand) from larger material and offers essential ground reinforcement. The geotextile fabric can be used in conjunction with a geogrid to further increase the sub-bases ground reinforcement strength.

Geotextile Mesh for Contaminated Land

Contaminated land geotextile mesh is a high visibility orange thermally bonded non-woven geotextile, bonded to a bright yellow coloured high density polyethylene plastic mesh. The geo-textile mesh is essential to separate contaminated land from clean soils on land remediation projects where contaminated land causes a significant environmental issue. The contaminated land HDPE mesh reinforced geotextile, offers a high visibility signal barrier for future excavations of the contaminated land hazard beneath. The geotextile limits particle transmission between the clean new soil and the contaminated substrate below. The geo-textile is designed to allow the transmission of water but act as a barrier to particles of larger size, i.e. rocks, stones and soil contaminants, eliminating physical contact. The laminated HDPE plastic mesh provides additional strength and reinforcement, increases puncture resistance, coupled with excellent visibility properties.

Geotextile composites

Geotextiles, geogrids and geomembranes are just some of the products that have been combined into geocomposite products answering the specific problems of customer needs; whether it be soil reinforcement, ground stabilisation, filtration, drainage, protection or erosion control and products such as geogrids and geomeshes have been developed. Overall, these materials are referred to as geosynthetics and each configuration—-geonets, geogrids and others - can yield benefits in geotechnical and environmental engineering design.
