Issue

Rainwater flooding

Flooding due to heavy rainfall or high surface water levels.

When heavy rainfall occurs, pavement and sewers flood.

Solution

Bufferklinker

The Bufferklinker is a concrete street clinker brick with an integrated cavity under the driving surface. The cavities are connected by lateral canals which enables a better infiltration and delayed drainage. By placing the Bufferklinker under pavement, rainwater can be stored under the pavement (up to 80 liters per square meter) without using the sewage system.

Bufferklinker

Pros

  • Reduction in costs for sewage system.
  • The solution is applicable everywhere because the rainwater is stored in the upper 35 cm.
