Structures must have drainage systems to quickly cut off water penetration routes before they affect the structures.
With a good drainage system :
The usefull life of a scheme is prolonged.
The safety factor of the structure is increased.
INTERDRAIN, the effective and lasting drainage system:
It enormously reduces the water-structure contact time preventing the water to reach the struuctrue consequently reducing the hydrostatic pressure and increasing the durability of materials.
It prevents the appearance of damp making the structure safer and operative (prevents leaks, puddles, etc.).
It reduces maintenance costs.
Main applications of INTERDRAIN in the batter of structures:
INTERDRAIN offers 2 drainage systems and a mixed drainage/sealing solution:
Reinforced earth walls are an economical alternative to traditional concrete walls in that the earth on the site can be used as fill. The most common reinforced earth walls are made with a facing wich can be:
Usually the existing site has low permeability (K<10^-5 m/s) so it does not have drainage properties. If damp or ground water is present, this willnot drain away and will not drain away and will reach the reinforced earth. The water reduces the properties of the soil and destabilizes the wall. In these conditions, the solution is to fit the INTERDRAIN GMG drainage geocomposite on the batter of the reinforced earth structure (see diagrams)
