Groundwater drainage

PROBLEM:
During the construction of a water ponds, flows of underground water and water tables can be intercepted, wich must be drained to eliminate the hydrostatic pressure and guarantee the stability of the structure.

SOLUTION:
The fitting of INTERMAS geocomposites below the waterproofing allows:

  • Interception of underground flows.
  • Lowering the water table.
  • Cutting capillary ascents in clayey and loamy soils.

As INTERMAS geocomposites protects the geomembrane, it is not necessary to fit heavy protection geotextiles.

Gas venting

PROBLEM:
When designing and building a water ponds, it is advisable to analyse the presence of biogas in the subsoil (decomposition of organic material). The perfect impermeability of HDPE geomembranes is an impenetrable barrier to the gas on its route upwards. It accumulates below the geomembrane and exercises continuouspressure on the plastic. Pockets of biogas form, breaking the membrane and destabilizing the water ponds.

SOLUTION:
INTERMAS geocomposites fitted bellow the geomembrane is the solution.

  • It intercepts the ascent of gas.
  • It quickly conducts it to the grooved drain pipes (which direct it away from the area occupied by the basin)
  • It eliminates the pressure due to trapped gas.
  • It prevents the formation of dangerous pockets of biogas.

TRINTER R Channels

Canal

Turf reinforcement mats are specifically designed to protect the surface from external erosive agents by improving the soil retention factor and easing the growth of vegetation, resulting in a green and sustainable solution.
Formed by the combination of two structural HDPE nets and one intermediate reinforcing PET geogrid.
