Unsealed traffic areas

For the traffic areas, INTEWA opted for a solution with TTE plastic lawn grid slabs from Hübner-Lee with a paving stone insert. The highly resilient system has a high load distribution due to integrated interlocking. This allows a lower construction height for load distribution, protects the revitalised soil zone, increases permeability and thus also the vegetation capacity.

Surface infiltration TTE

  • near-natural, decentralised infiltration
  • Preservation of the revitalised soil layer
  • Treatment of polluted precipitation runoff
  • Groundwater protection and recharge
  • approx. 420 m²
  • Recycled plastic
  • High load-bearing capacity (SLW60) due to load distribution

Gravel areas

Approx. 500 m²
