Foundation Protection

Water barriers and drainage facilitation


foundation systems


  • Reliably protects and insulates waterproofing layers against mechanical damage

  • Withstands extreme compression loads of 400 kN/m2 (up to type-60 heavy trucks, depending on the covering).

  • High drainage capacity prevents frost damage and encrustations.

  • Water-vapour pressure is drained away through the structure

  • Water drainage capacity exceeds that of gravel or chipping layers.

  • No obstruction by sludge underneath the covering layer

  • Good load distribution prevents point loads on the waterproofing layer

  • Resultant static building loads lower than those of gravel layers

  • Easy and cost-efficient installation.
