Geotextiles
Geotextiles are used for their filtration, separation, reinforcement, drainage and load distribution properties.
However, there are two types;
(a) Woven Geotextiles are woven multifilament manufactured from high-tenacity polyester filament yarns. These have high tensile strengths, low elongation, low creep and excellent durability; they are recommended for applications where the predominant geosynthetic function is reinforcement. With its low apparent opening size and adequate permeability, the Geotextile can also perform the function of separation and, to a limited extent, filtration.
(b) Non-woven Geotextile is a felt-like synthetic fabric made of randomly bonded polypropylene or polyester fibres that excels at water permeability, filtration and soil separation.
FUNCTIONS
Here, the geotextile is place in between two non-homogenous layers, by doing this it separates and maintains the integrity of the individual layers. It also helps to improving long term stress relief.Â
The geotextile allows for percolation across its total surface area and retains the materials on the upstream side. The key component to check when choosing a geotextile for a design is the pore opening size, this determines the flow rate and the amount of fine particle that can me retained on the upstream side of the geotextile.Â
The geotextile chosen should have the right hydraulic properties required to improve the stabilization of the soil & geotextile combination.Â
When used as a geocomposite in engineered landfill solutions , the geotextile allows the passage of liquid (and gas) across its total surface area. The key component that provides this function is the transmissivity of the geotextile.
Hoffman Geosolutions has distribution arms in Lagos, Abuja and Port Harcourt, and we supply a wide range of woven and non-woven Geotextiles. We also provide professional installation and supervisory services to ensure the integrity of the materials deployed. Â
