Composite for geotechnics, building and the like, with impermeable layer

Abstract

A composite (1) for geotechnics, building and the like, with an impermeable layer, comprising a sheet-like element (2) that is impermeable to fluids and has, monolithically therewith, elements (10, 12) that protrude on the first and second faces, on at least one of the faces there being a layer (5) that is integrally coupled to the protruding elements to form, at the first and / or second faces, two separate drainage and / or protection and / or grip systems adapted to withstand intense compression along a direction that is substantially perpendicular to the sheet-like element.

Description

technical field [0001] The invention relates to a composite material for use in geotechnical, construction etc., which composite material has an impermeable layer. Background technique [0002] It is known in geotechnical technology, construction etc. to commonly use impermeable layers or elements which can be used to cover or be covered by other materials. [0003] Usually the impermeable element is provided with a membrane made of medium density polyethylene or high density polyethylene which is covered by or covered with material such as soil, waste, silt, natural elements, concrete etc. [0004] In construction, membranes are used both vertically and horizontally to insulate or separate buildings from the ground to form insulating and drainage elements. [0005] In the geotechnical field, these membranes are used in the construction of landfills, as elements to contain waste, to make the landfill depressions impermeable, and to cover and seal the landfill when the landf...

AI Technical Summary

Problems solved by technology

[0012] The use of separate elements creates problems when the layer is applied on an inclined plane due to possible slippage of the cover material overlying the geocomposite and / or the geotechnical Slippage may occur with the composite material and / or the membrane over the underlying geocomposite and / or the geocomposite over the cover material may cause interaction Some problems in terms of friction, correspondingly will bring problems in terms of friction

[0024] The face without raised elements has no fastening features such that the membrane may slip on the overlying material, thus failing to resolve the interface between the membrane and the geotechnical load material applied on one of the two sides. The problem
