Waterproofing Contractor Pacific Palisades
Surfacing And Waterproofing is a licensed and bonded waterproofing contractor serving Pacific Palisades with 25+ years of experience. We specialize in below-grade waterproofing for new construction and existing structures, including basements, foundations, retaining walls, shoring walls, and other below-grade assemblies.
Our work includes liquid-applied, sheet-applied, blindside, pre-applied, and under-slab waterproofing systems, along with drainage boards, protection systems, waterstops, and critical waterproofing details. Each scope is reviewed with the project plans, specifications, site conditions, construction sequencing, and manufacturer requirements before installation begins.
We also provide deck and balcony waterproofing, swimming pool waterproofing, roof deck systems, TPO roofing, and sheet metal flashing for residential and commercial properties throughout Pacific Palisades.
Below-Grade and Basement Waterproofing
Below-grade waterproofing protects basements, foundations, and other structures that are in direct contact with soil and groundwater. These areas require a complete system that addresses both water intrusion and drainage around the structure.
We install liquid-applied and sheet-applied waterproofing membranes for basement walls, foundation walls, and other below-grade surfaces. Waterproofing assemblies can include drainage boards, protection boards, perimeter drainage, and waterstops to provide long-term protection against groundwater and hydrostatic pressure.
Critical areas such as wall-to-footing transitions, penetrations, construction joints, and termination bars are detailed as part of the waterproofing system.
Retaining Wall and Shoring Wall Waterproofing
Retaining walls and shoring walls present different waterproofing challenges than conventional exterior walls, particularly on hillside and limited-access properties.
We install waterproofing systems for retaining walls that combine a continuous membrane with drainage and protection layers behind the wall. Proper drainage helps relieve water buildup while the waterproofing membrane protects the structure from moisture intrusion.
For shoring-wall construction, waterproofing may need to be installed before the structural wall is placed because exterior access will no longer be available afterward. This requires the waterproofing installation to be coordinated with the shoring and concrete work from the beginning.
Blindside, Pre-Applied and Under-Slab Waterproofing
Blindside waterproofing is used where there is little or no access to the exterior side of a completed below-grade wall. The membrane is installed against the shoring or property-line condition before the structural wall is constructed.
Pre-applied waterproofing systems can also be installed before concrete placement, allowing the membrane to become part of the below-grade waterproofing assembly as construction progresses.
For structures requiring waterproofing beneath the building, we install under-slab membranes and connect the horizontal waterproofing to the vertical wall system. This creates continuity around the below-grade portion of the structure.
These systems are especially useful for basements, property-line construction, and hillside projects where conventional exterior waterproofing access is limited.
Foundation Drainage, Waterstops and Waterproofing Details
A below-grade waterproofing system involves more than the membrane itself. Drainage, protection, joints, and penetrations all affect how the finished assembly performs.
Drainage boards help move water away from below-grade walls, while protection boards protect the waterproofing membrane during construction and backfill. French drains can collect and redirect water at the base of the structure.
Waterstops are used at concrete construction joints to help prevent water from traveling through joints in the structure. We also detail pipe penetrations, utility penetrations, slab transitions, footing transitions, drains, and membrane terminations as part of the waterproofing scope.
Why Choose Surfacing And Waterproofing?
25+ Years of Experience
Our experience includes below-grade waterproofing, decks, balconies, roofing, swimming pools, and other waterproofing applications.
Coordination With Other Trades
Below-grade waterproofing often needs to be completed in sequence with shoring, concrete, plumbing, drainage, sheet metal, and backfill work. We coordinate our installation with the construction schedule and adjacent trades.
Complete Waterproofing Systems
We look at the entire assembly—including membranes, drainage, protection, waterstops, flashing, penetrations, and transitions—not just the exposed waterproofing material.
Licensed and Bonded
Surfacing And Waterproofing holds California contractor license #1055191.
Technical Waterproofing Experience
Our team works with liquid-applied, sheet-applied, blindside, pre-applied, under-slab, traffic-bearing, and roofing systems.
Waterproofing for Hillside Properties
Hillside construction in Pacific Palisades can include basements, retaining walls, shoring systems, below-grade living areas, and structures built into sloped terrain.
These projects often require several waterproofing components to work together—from the retaining or shoring wall to the basement walls, foundation drainage, and below-grade slab.
Our team coordinates the waterproofing installation with the surrounding construction so areas that will later be covered by concrete, protection board, soil, or backfill are completed before access is lost.
Deck, Balcony and Swimming Pool Waterproofing
We also install waterproofing systems for decks, balconies, walkways, and other occupied exterior surfaces.
Deck and balcony waterproofing can include substrate preparation, reinforced membranes, drainage detailing, flashing, and traffic-bearing coatings. Particular attention is given to drains, door thresholds, wall transitions, penetrations, and railing attachment areas where water intrusion commonly develops.
For swimming pools and water-containing structures, we provide waterproofing systems designed to protect the underlying structure before the final pool finish or surfacing system is installed.
Roof Deck Waterproofing and TPO Roofing
Occupied roof decks require waterproofing that protects the building while supporting regular foot traffic and exposure to weather. We install reinforced roof deck waterproofing systems and traffic-bearing finishes for these applications.
We also install TPO roofing systems for low-slope roofs. Roof drains, parapets, curbs, penetrations, and terminations are integrated into the roofing assembly to maintain continuous weather protection.
Sheet Metal Flashing and Waterproofing Details
Sheet metal flashing is an important part of many waterproofing and roofing assemblies. We fabricate and install flashing at roof and wall transitions, parapets, doors, windows, penetrations, deck edges, and other locations where waterproofing systems meet adjacent building components.
The goal is to create a properly integrated transition between the membrane and surrounding construction rather than treating the flashing as a separate component.

Waterproofing for New Construction and Existing Properties
We work with general contractors, builders, developers, property owners, and project teams throughout Pacific Palisades.
For new construction, early waterproofing coordination is particularly important for shoring walls, blindside membranes, under-slab systems, waterstops, penetrations, and below-grade drainage because these areas can become inaccessible as construction progresses.
For existing properties, we evaluate the source and conditions of water intrusion before recommending a waterproofing approach. Existing projects may involve basements, retaining walls, decks, balconies, roof decks, pools, or other areas where the original waterproofing system has failed or requires replacement.
Pacific Palisades Waterproofing FAQs
Do you provide waterproofing for shoring walls and blindside conditions?
Yes. We install blindside and pre-applied waterproofing systems where the membrane must be installed against the shoring before the permanent structural wall is constructed.
Can you install waterproofing before concrete or shotcrete placement?
Yes. Pre-applied waterproofing can be installed before concrete placement for below-grade walls and other applications where the waterproofing will not be accessible after construction. The specific membrane must be compatible with the construction method; some approved systems have restrictions on shotcrete applications.
Do you install under-slab waterproofing?
Yes. We install under-slab waterproofing and connect the horizontal membrane to the vertical below-grade waterproofing system to maintain continuity around the structure.
Do you waterproof basements and retaining walls in the Pacific Palisades?
Yes. We install below-grade waterproofing systems for basements, foundation walls, retaining walls, and other earth-retaining structures, including membrane, drainage, and protection components.
Do you install drainage boards, protection boards, and French drains?
Yes. We install drainage and protection components used with below-grade waterproofing systems, including drainage boards, protection boards, and French drains.
Can you review waterproofing plans and details before installation?
Yes. We review waterproofing plans, specifications, details, and manufacturer requirements to identify the waterproofing system and critical transitions before installation begins.
Do you coordinate waterproofing with the shoring and concrete contractors?
Yes. Blindside, pre-applied, under-slab, and other below-grade systems often need to be installed at specific stages before concrete placement or before areas become inaccessible. We coordinate our waterproofing scope with the project schedule and adjacent trades.
What below-grade waterproofing systems do you install?
