The main functions of Hy-Tex Terralys™ geotextiles can be summarised as follows:
Separation Hy-Tex Terralys™ geotextiles prevent the intermixing of materials with different grades or structure.
This improves compaction and load bearing capacity, while ensuring long term drainage performance.
It also minimises the need for ground excavation, enables work to proceed during adverse weather, reduces the amount of costly aggregate and extends the effective life of the structure.
Filtration Hy-Tex Terralys™ geotextiles permit free flow of water whilst retaining fines (sand/silt).
This prevents the build up of hydraulic pressure, ensures the drainage medium remains unclogged, and provides efficient long term performance and low maintenance.
Furthermore, it also allows less expensive aggregate to be used.
Reinforcement Hy-Tex Terralys™ geotextiles increase ground stability by distributing and supporting loads.
The high tensile strengths of woven geotextiles, combined with their frictional resistance, restrain ground movement and deformation from imposed loads, whilst spreading localised stresses from individual stones.
This permits alternative designs and provides cost effective solutions.
