Restoration Curtain grouting

Curtain grouting waterproofs structural elements which are particularly porous or permeable (brick, stone or Predal walls) creating a resin membrane between the wall and the diaphragm or between the wall and the ground behind.

The resin is injected through a grid of holes and spreads from each point radially, creating an elastic, foam surface in the area behind the wall. It also fills the joints between bricks, stones or predal sections (see picture).

Curtain grouting techniques comply with the WTA 4-6-98 recommendation.
