Waterproofing Contractor Encino
Surfacing And Waterproofing is a licensed and bonded waterproofing contractor serving Encino with 25+ years of experience. We provide waterproofing for residential, multifamily, commercial, and new-construction projects.
Our services include below-grade and basement waterproofing, subterranean walls, parking areas, decks, balconies, retaining walls, roof decks, and TPO roofing. We work with liquid-applied and sheet membranes, pre-applied systems, drainage components, waterproof coatings, waterstops, and sheet metal flashing.
From hillside residences south of Ventura Boulevard to multifamily and commercial construction along the Ventura corridor, our team handles waterproofing systems at different stages of construction.
Waterproofing for Subterranean Construction
Subterranean construction creates waterproofing conditions that need to be addressed before the structure is enclosed or backfilled. Basement walls, underground parking areas, foundation walls, and slabs can all be exposed to moisture from the surrounding soil.
We install waterproofing membranes on vertical below-grade surfaces and beneath slabs, with connections between horizontal and vertical systems where required. Depending on access and construction sequence, the project may use positive-side, pre-applied, blindside, or under-slab waterproofing.
Waterstops can also be incorporated at concrete construction joints as part of the below-grade waterproofing design.
Multifamily and Commercial Waterproofing
Multifamily and commercial buildings can contain several waterproofing conditions within one project, from subterranean parking and foundation walls to balconies, common walkways, decks, and low-slope roofs.
We work with general contractors, developers, and property managers to install the specified systems at each location and coordinate areas where waterproofing interfaces with concrete, drains, doors, walls, roofing, and other building components.
For new construction, we can review waterproofing plans and specifications before installation and provide product documentation and submittal information when required.

Experience With New Construction
We understand waterproofing sequencing around concrete placement, penetrations, drains, backfill, roofing, and adjacent trades.
Basement, Foundation and Retaining Wall Waterproofing
For basement and foundation walls where the exterior face remains accessible, waterproofing is typically installed before drainage materials and backfill.
The wall is prepared for the specified membrane, followed by the waterproofing application and compatible drainage and protection components. French drains can be incorporated at the base of the structure to collect and redirect water.
We also waterproof retaining walls and other below-grade structures using systems selected for the wall construction and project requirements.
Parking and Elevated Deck Waterproofing
Parking decks and elevated exterior surfaces require a durable waterproofing system capable of protecting the concrete structure from water exposure and regular use.
Depending on the application, installation can include primers, reinforced liquid-applied membranes, intermediate waterproofing coats, aggregate, and protective finish coats. Ramps, drains, expansion joints, curbs, and transitions receive compatible detailing as part of the system.
For existing structures, the condition of the concrete and existing waterproofing is evaluated before determining whether the scope requires restoration, recoating, or membrane replacement.
Balcony and Walkway Waterproofing
Balconies and exterior walkways are waterproofed using multi-layer systems designed to protect the occupied or enclosed areas below.
Installation can include substrate preparation, primer, reinforced membrane layers, waterproof base coats, and UV-resistant exterior finishes. The membrane is integrated with drains, thresholds, wall connections, perimeter edges, and other termination points rather than stopping at the main walking surface.
For multifamily properties, these systems can be installed across individual balconies, shared walkways, stairs, and other exterior circulation areas.
Hillside Property Waterproofing
The hillside portions of Encino create another type of waterproofing work. Residential construction in these areas can involve retaining structures, deep foundations, lower levels built into the slope, elevated decks, and complex changes in grade. Actual Encino hillside construction includes projects using extensive caisson foundations and retaining walls.
We waterproof basement walls and other below-grade areas while coordinating the membrane with drainage, concrete, and surrounding construction.
Where exterior access will disappear as the structure progresses, the waterproofing sequence is established before those areas are closed.
Roof Deck Waterproofing and TPO Roofing
We install waterproofing for occupied roof decks and TPO membrane roofing for low-slope residential, multifamily, and commercial roofs.
TPO is a reinforced single-ply thermoplastic membrane. Sheets are laid across the prepared roof assembly and heat-welded at the seams to create a continuous roofing surface. Depending on the roof design, the assembly may also include insulation, cover board, fastening components, and manufacturer-compatible accessories.
The membrane is integrated with drains, parapets, curbs, penetrations, roof edges, and sheet metal flashing to complete the roofing system.
Waterproofing Materials and Systems
Different parts of a building can require very different waterproofing materials. Our work includes liquid-applied membranes, sheet membranes, pre-applied membranes, cementitious waterproofing, single-ply TPO roofing, primers, reinforced coating systems, drainage boards, protection boards, waterstops, sealants, and sheet metal components.
We work with established waterproofing manufacturers and select products according to the specified application, substrate, exposure, and compatibility with adjacent materials.
This allows us to handle the complete waterproofing scope without treating every area of a project as if it requires the same membrane.
Waterproofing Plan Review and Project Coordination
Waterproofing details on larger projects often cross several scopes. Concrete penetrations need to be in the correct locations, drains must interface with the membrane, wall waterproofing may need to be completed before backfill, and roofing or deck membranes must terminate correctly at adjacent construction.
We review plans and specifications to understand these interfaces before our work begins and coordinate our installation with the GC and affected trades.
For below-grade construction, early coordination is especially important because correcting a missed waterproofing detail becomes significantly more difficult after concrete, backfill, or subsequent construction covers the area.
Encino Waterproofing FAQs
Can you waterproof subterranean parking structures?
Yes. We provide waterproofing for subterranean walls, below-grade concrete, slabs, ramps, and related areas. The system depends on the structure, access, drainage conditions, and project specifications.
When should the waterproofing contractor start on a new construction project?
For below-grade construction, waterproofing coordination should begin before concrete placement and backfill. Under-slab membranes, pre-applied systems, waterstops, penetrations, and wall transitions may need to be installed or coordinated before those areas become inaccessible.
Can you waterproof a project with two or more subterranean levels?
Yes. Multi-level below-grade construction can require waterproofing at exterior walls, slabs, construction joints, penetrations, and transitions between different parts of the structure. We review the plans and specified waterproofing system before installation.
Do you work on multifamily and mixed-use developments in Encino?
Yes. We provide waterproofing for multifamily and mixed-use projects, including below-grade areas, parking structures, balconies, walkways, decks, and low-slope roofs.
What waterproofing materials do you use for below-grade concrete?
Depending on the plans and application, below-grade construction can use liquid-applied, sheet-applied, pre-applied, blindside, or under-slab membranes together with drainage, protection, waterstops, and compatible detailing materials.
Can you provide waterproofing submittals and product data?
Yes. When required for the project, we can provide manufacturer product information and documentation for the waterproofing materials included in our scope.
Can you coordinate waterproofing with the concrete contractor?
Yes. We coordinate locations where waterproofing interfaces with concrete placement, construction joints, penetrations, waterstops, slabs, walls, and other work that can affect the completed waterproofing system.
Can existing apartment or commercial buildings be waterproofed without replacing every system?
It depends on the existing condition. We evaluate the substrate and existing waterproofing to determine whether an area can be restored or recoated or whether the existing membrane needs to be removed and replaced.
