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.
In Los Angeles, parking structures face unique challenges — from the intense UV exposure that breaks down surface coatings to the occasional heavy rains that exploit every crack and joint. Without a dedicated parking garage waterproofing system, water seeps through cracks and joints, corroding rebar and weakening the structure from within. Our traffic-grade deck coatings and vehicular deck waterproofing systems are engineered to handle the combined stress of vehicular loads, tire abrasion, temperature shifts, vehicle fluids, and environmental exposure. We use polyurethane parking deck coatings and Tremco PUMA waterproofing technology and other proven waterproofing systems selected according to the project’s requirements, structural design, and manufacturer recommendations to provide durable, long-term performance.
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.

What types of parking structures do you waterproof?
We waterproof all types of parking structures including multi-level parking garages, open concrete parking lots, podium and plaza decks, drive ramps and loading areas, below-grade parking structures, and underground garage slabs. Our systems are designed for both new construction and existing parking structures across Los Angeles County.
What waterproofing materials do you use for parking garages?
We use polyurethane-methacrylate systems such as Tremco PUMA Technology and vehicular deck waterproofing systems by Poly-Tuff Systems International, selected for their durability, chemical resistance, and fast curing times. We also install fluid-applied and spray-applied waterproofing membranes based on the specific requirements of each project. For below-grade parking structures, waterproofing assemblies may include protection boards and drainage mats on the positive side of the structure where needed.
How long does parking garage waterproofing last?
Our traffic-grade waterproofing systems are designed for durability and performance in accordance with manufacturer specifications and installation requirements.
Can you waterproof an existing parking garage with leaks?
Yes. We provide parking garage waterproofing solutions for existing structures. Our team will inspect the existing conditions, identify potential water intrusion points, and determine the appropriate waterproofing system for the parking structure.
Do you handle both above-grade and below-grade parking waterproofing?
Yes. We waterproof both above-grade parking decks and ramps and below-grade parking structures, including underground garages, retaining walls, and foundation walls. Above-grade areas typically receive traffic-bearing waterproofing systems, while below-grade structures can incorporate positive-side waterproofing membranes with protection and drainage boards.
