Professional Below-Grade Protection for Structural Walls
We install complete foundation waterproofing systems throughout Los Angeles, Pacific Palisades, and Malibu, designed to protect structural walls from groundwater intrusion and hydrostatic pressure.
Our work begins once the foundation or retaining wall is built—applying membranes, drainage, and detailing to create a continuous, long-term waterproof barrier.
Why Foundation Waterproofing Is Critical
Concrete is durable, but it is not waterproof. In hillside and coastal areas of Los Angeles County, groundwater and hydrostatic pressure can migrate through pores, cold joints, and penetrations, leading to long-term moisture problems.
Properly installed waterproofing ensures the foundation remains dry and structurally protected for decades.
We install complete assemblies that integrate membranes, protection boards, and perimeter drainage—keeping the wall dry and the structure protected from below-grade moisture.
Our Foundation Waterproofing Systems
Fluid-Applied Membranes
Seamless, cold-applied membranes form a continuous barrier over concrete or shotcrete surfaces. Ideal for complex detailing, fluid membranes bond directly to the substrate and are combined with protection boards and drainage composites for long-term durability.
Bentonite Sheet Membranes
Self-sealing bentonite liners are used for foundation and retaining walls, especially in Pacific Palisades and Malibu where soil moisture and hydrostatic pressure are constant challenges. Once hydrated and confined, bentonite expands to fill small voids, creating a self-healing barrier.
Drainage & Protection Boards
Installed over membranes to relieve water pressure and protect the system during backfill. These boards allow groundwater to flow vertically toward footing drains, minimizing pressure against the wall.
Perimeter Drainage Systems
Gravel-wrapped French drains, filter fabrics, and cleanouts are installed at footing level to redirect groundwater away from the structure. Where gravity flow isn’t possible, sump tie-ins are incorporated for active dewatering.
Detailing & System Integration
Every waterproofing installation includes careful detailing around:
Cold joints and footing-to-wall transitions
Wall penetrations, pipe sleeves, and embedded hardware
Tie-backs, anchors, and re-entrant corners
Terminations at grade lines and horizontal connections
All installations follow manufacturer specifications and Division 07 waterproofing standards for consistency and performance.
Surface Preparation & Quality Control
Effective foundation waterproofing requires proper substrate preparation.
We ensure:
Surfaces are clean, sound, and free of laitance or debris
Honeycombs or voids are repaired before membrane application
Moisture and temperature conditions meet system requirements
Membranes are fully protected before backfill or ongoing trades
Hydrostatic Pressure Management
In hillside and coastal conditions like Malibu and Pacific Palisades, groundwater movement exerts significant pressure on below-grade walls.
Our waterproofing systems include vertical drainage composites and perimeter drains that reduce this pressure and extend system life.
Applications
Foundation walls and footings
Retaining walls on hillside properties
Basement and podium walls
Shotcrete or lagging walls post-shoring
Structural walls in subterranean garages
