Waterproofing Contractor Calabasas
Surfacing And Waterproofing is a licensed and bonded waterproofing contractor serving Calabasas with 25+ years of experience. We provide waterproofing for custom homes, hillside properties, new construction, renovations, and commercial buildings.
Our services include basement and below-grade waterproofing, retaining walls, decks and balconies, swimming pools, roof decks, and TPO roofing. We install liquid-applied and sheet-applied membranes, drainage and protection systems, traffic-bearing coatings, waterstops, and related waterproofing details.
From below-grade structures built into sloped terrain to exterior decks and swimming pools, our team provides waterproofing systems designed around the construction and use of each area.
Waterproofing for Hillside and Custom Homes
Hillside and custom-home projects can bring several waterproofing conditions together on the same property. Basements and other below-grade areas may extend into the hillside, retaining walls may support portions of the site, and decks, balconies, pools, and roofs can create additional areas requiring water protection.
We provide waterproofing for these different parts of the property and address the transitions where one waterproofing condition connects with another.
For new construction, we can review the waterproofing scope before installation so below-grade areas and other locations that will later become inaccessible are completed at the appropriate stage of construction.
Retaining Wall Waterproofing
Water behind a retaining wall needs to be managed rather than trapped against the structure. We install retaining wall waterproofing systems that combine a waterproofing membrane with drainage and protection components.
Drainage boards help direct water downward, while protection boards protect the waterproofing membrane during construction and backfill. French drains can collect and redirect water at the base of the wall.
We waterproof poured concrete, shotcrete, and other retaining wall conditions for residential and commercial projects.

Experience With Complex Projects
We work on waterproofing projects involving multiple elevations, retaining structures, below-grade areas, occupied decks, pools, and other conditions where several waterproofing systems may be required.
Basement and Below-Grade Waterproofing
We install waterproofing systems for basements, foundation walls, subterranean spaces, and other structures in contact with soil.
Positive-side waterproofing can be applied to the exterior face of below-grade walls before the structure is backfilled. Where exterior access will not be available after construction, pre-applied or blindside systems may be used instead.
Our below-grade work can also include waterstops, penetrations, construction joints, footing transitions, drainage components, and connections between horizontal and vertical waterproofing.
Below-Grade Waterproofing and Drainage Systems
A complete below-grade waterproofing system may extend from beneath the concrete slab to the exterior face of basement and retaining walls. For new construction, we can install under-slab and pre-applied membranes before concrete placement and connect them to the waterproofing at adjoining walls.
Drainage is incorporated where required to manage water around the structure. Drainage boards direct water along below-grade walls, protection boards protect the membrane during backfill, and French drains collect and redirect water at the base of the structure.
This approach allows the membrane, drainage, and protection components to function together around basements, foundations, and retaining walls.
Swimming Pool and Pool Deck Waterproofing
We install swimming pool waterproofing systems using professional-grade cementitious and liquid-applied membranes designed for continuous water exposure. Depending on the pool construction and final finish, systems may include products from manufacturers such as Sika, Tremco, CIM, and Pacific Polymers.
The waterproofing membrane is applied continuously across the prepared pool shell to create a watertight barrier beneath the final pool finish. Depending on the selected system, installation may include multiple membrane coats, reinforcement, primers, and compatible sealants.
For pool decks and surrounding walking areas, we install waterproofing and traffic-bearing coating systems designed for exterior exposure, foot traffic, and wet conditions.
Deck and Balcony Waterproofing
Decks and balconies need a waterproof surface that can withstand weather, sunlight, and regular use while protecting the structure below.
We install multi-layer waterproofing systems for residential balconies, elevated decks, walkways, and commercial deck areas. Depending on the application, systems may include primers, reinforced liquid-applied membranes, waterproof base coats, and durable UV-resistant finish coats.
The installation process includes proper substrate preparation, membrane application, reinforcement where required, and integration with drains, door thresholds, deck edges, railing attachments, wall transitions, and penetrations.
Commercial and Traffic-Bearing Waterproofing
Parking areas, pedestrian decks, walkways, and other heavily used surfaces require waterproofing systems capable of handling regular traffic.
We install liquid-applied waterproofing systems with reinforced details and traffic-bearing finishes for pedestrian and vehicular applications. Slip-resistant aggregate and UV-resistant topcoats can be incorporated into exposed systems.
Drainage, expansion joints, terminations, and transitions are addressed as part of the waterproofing scope.
New Construction Waterproofing Coordination
Waterproofing is often installed between the work of several different trades. Below-grade membranes may need to be completed before concrete placement or backfill, while drains, penetrations, flashing, and other components may need to be in place before the waterproofing can be completed.
We work with general contractors, builders, developers, architects, and project teams to coordinate our waterproofing scope with concrete, grading, drainage, plumbing, roofing, and other adjacent work.
We can review project plans, specifications, and waterproofing details before installation and provide product information and manufacturer documentation when required for the project.
Roof Deck Waterproofing and TPO Roofing
We provide waterproofing for occupied roof decks and install TPO roofing systems for low-slope roofs on residential and commercial properties.
TPO roofing uses a reinforced single-ply thermoplastic membrane installed over the prepared roof assembly. The membrane sheets are positioned across the roof and heat-welded together at the seams, creating a continuous waterproof roofing surface. Depending on the roof design, the system can also include insulation, cover board, attachment components, and compatible accessories.
Calabasas Waterproofing FAQs
Do you waterproof retaining walls on hillside properties?
Yes. We install waterproofing systems for retaining walls and below-grade structures, including waterproofing membranes, drainage boards, protection systems, and French drains where required by the project.
What waterproofing system should be used for a basement or subterranean wall?
The appropriate system depends on the wall construction, access, groundwater and drainage conditions, and project specifications. We install liquid-applied, sheet-applied, pre-applied, blindside, and other below-grade waterproofing systems.
Can you waterproof a new basement before the walls are backfilled?
Yes. Positive-side waterproofing can be installed on the exterior side of basement and foundation walls before drainage components, protection layers, and backfill are installed.
Do you provide waterproofing for new custom-home construction in Calabasas?
Yes. We provide waterproofing for new construction, including basements, retaining walls, foundations, under-slab areas, decks, balconies, swimming pools, and roof decks.
Can you review the waterproofing details in our construction plans?
Yes. We review project plans, specifications, wall sections, waterproofing details, and manufacturer requirements to determine the waterproofing scope before installation.
Do you coordinate waterproofing with grading, drainage, concrete, and backfill work?
Yes. Below-grade waterproofing often needs to be coordinated with concrete, drainage, grading, and backfill because portions of the waterproofing system become inaccessible as construction progresses.
Do you waterproof swimming pools and pool decks?
Yes. We install waterproofing systems for swimming pools, pool decks, and surrounding exterior areas for residential and commercial projects.
Do you provide waterproofing submittals for construction projects?
Yes. When required, we can provide product information and manufacturer documentation for waterproofing materials included in our scope.
