Below-Grade Retaining Wall Waterproofing in Beverly Hills Using Sikalastic®-320 NS
Retaining Wall Waterproofing Installation
Drainage and Membrane Protection
After the waterproofing membrane was completed, a drainage mat was installed over the retaining wall system before backfilling. The drainage layer helps protect the membrane from damage while creating a continuous path for water to move downward toward the French drain system at the base of the wall. This combination reduces water buildup against the retaining wall and allows the waterproofing and drainage components to work together as one complete below-grade system. At Surfacing And Waterproofing, we focus on properly integrating each component to provide reliable long-term protection below grade.
What is the best way to waterproof a retaining wall?
The most effective approach is to combine a below-grade waterproofing membrane with a drainage system that manages water behind the wall. For this Beverly Hills project, the system included Sikalastic®-320 NS, drainage mat, and a French drain system.
How do you protect a retaining wall from water?
Water should be addressed with both waterproofing and drainage. The membrane helps prevent water from penetrating the wall, while the drainage mat and French drain provide a path for water to move away from the structure and help reduce hydrostatic pressure.
What is the best waterproofing for concrete block retaining walls?
Liquid-applied waterproofing membranes are commonly used because they create a seamless barrier and can conform to the wall surface without field seams. The appropriate system depends on the wall construction, site conditions, and project specifications.
