Retaining Wall Waterproofing

One of the most essential components of waterproofing is for below-ground structures. It is very expensive to rectify water damage in retaining walls, so it is important to apply the correct principles so the membrane system is sustainable for the long term.

Why retaining wall waterproofing matters

Retaining walls are used for practical and aesthetic purposes: providing terraces on sloping sites, creating usable garden space, and freeing up more usable area. All retaining walls need to be strong, safe and trouble-free. Their main job is to prevent soil from spilling onto lower levels and to retain the structure by controlling erosion, redirecting water and preventing land slips. Waterproofing helps reduce hydrostatic pressure and protects the back of the wall from moisture. If it is not done properly, moisture can seep through, leading to discolouration and loss of structural integrity.
