ECOMASA GROUP SL offers solutions that geosynthetics are used, among which we highlight the following:

Soil and foundation engineering (suspension assurance and soil reinforcement and asphalt)
Environmental technology (construction of landfills, remediation of contaminated land, seals, etc.)
We are leaders in waterproofing mines, landfills, ponds and reservoirs, using polyethylene geomembranes art.

We use the latest technology products to offer a total guarantee of a job well done.

In GROUP ECOMASA we are specialist in the construction and waterproofing of water dams and landfills.

Hundreds of completed throughout the national geography works guarantee.

In Group Ecomasa we use art materials to ensure exceptional finish and durability in all our work.

Some of the features models geosint’rticos materials used in our work are:

Tensile strength: depend on the geometry and the structure under overload.
Long-term strength: includes the various reducing factors due to the flow of the material, environmental and installation.
Coefficient of interaction with the ground: effective adhesion of armor with the surrounding soil.
Permeability: water flow capacity.
