Parking Garage & Parking Lot Waterproofing

Serving Los Angeles Pacific Palisades And Malibu

Complete Traffic-Grade Waterproofing Systems for Vehicular and Structural Surfaces

We specialize in parking garage and parking lot waterproofing across Los Angeles, Pacific Palisades, and Malibu, protecting structural concrete from water intrusion, de-icing salts, and heavy traffic wear.
Our systems create seamless, long-term barriers that prevent corrosion, leaks, and concrete deterioration in both multi-level parking garages and open-air parking lots.

Why Parking Structures Need Waterproofing

Parking areas experience constant exposure — rain, tire abrasion, temperature shifts, and vehicle fluids.
Without a dedicated waterproofing system, water seeps through cracks and joints, corroding rebar and weakening the structure.
Waterproofing preserves the concrete’s integrity, protects reinforcing steel, and prevents costly structural repairs.

We design and install traffic-grade waterproofing assemblies that combine membranes, coatings, and drainage layers to handle both vehicular loads and environmental exposure.

Our Waterproofing Solutions

We waterproof both above- and below-grade parking structures, applying high-performance membrane systems to protect decks, ramps, and ceilings from water penetration.
Our assemblies integrate:

Fluid-applied or spray-applied membranes for seamless coverage
Crack-bridging elastomeric coatings resistant to thermal expansion
Drainage mats and protection boards for hydrostatic pressure relief
Expansion-joint sealing for continuity between structural sections

We use advanced polyurethane-methacrylate systems such as Tremco PUMA Technology by Tremco Sealants and vehicular deck coatings by Poly-Tuff Systems International, selected for their durability, chemical resistance, and fast curing times.

These systems are ideal for:

- Multi-level parking garages
- Podium decks above occupied space
- Entry ramps, drive aisles, and turning zones
- Underground garage slabs and retaining walls

2. Parking Lot Waterproofing

Open-surface parking lots and drive areas require different solutions — focused on surface protection, drainage, and durability.
We apply heavy-duty waterproof coatings that resist UV exposure, oils, and abrasion, forming a continuous seal over concrete and preventing moisture migration through joints and cracks.
Our process includes:
- Cleaning, surface profiling, and crack treatment
- Application of a flexible waterproofing membrane
- Optional traffic coatings for high-use areas
- Integration of positive slope and surface drainage
These assemblies protect against surface cracking, freeze-thaw damage, and subsurface moisture intrusion — extending the life of both the concrete and the finish layer.

Surface Preparation & Installation

Proper substrate preparation is essential for lasting results:

Surfaces are cleaned and shot-blasted to remove laitance and contaminants
Cracks, spalls, and control joints are repaired prior to membrane application
Primers and base coats are installed per manufacturer specifications
Reinforced membranes are cured and protected with topcoats or overburden

All installations are performed under Division 07 – Waterproofing standards and manufacturer guidelines.
