GEOSYNTHETIC MATERIALS

 

Drainage Membranes are applied in underground construction for minimizing the negative impact of water, as an advanced technological product. They protect the waterproofing of underground construction by replacing the infill concrete under foundations and also installed in roof gardens under the soil in combination to geotextiles. No special installation crew is required and the cost is considerably low. Geotextiles are non-woven fabrics made by polypropylene fibers. They are used as ground filter or reinforcement-separation membranes and also in reverted insulation (between gravel and thermal insulation), in roof gardens and over sensitive waterproofing membranes. They separate the backfill layers from the instable subsoil by preventing sinkage and allowing better concentration and increase of their strengths. Geotextiles during drainage pipes construction prevent incoming fine dust particles and prevent erosion of dams, bridge foundation and supporting walls.
