Waterproofing Contractor Brentwood
Surfacing And Waterproofing is a licensed and bonded waterproofing contractor serving Brentwood with 25+ years of experience. We work on custom residences, multifamily buildings, commercial properties, and new-construction projects throughout the area.
Our waterproofing work ranges from basements, foundations, retaining walls, and subterranean structures to balconies, decks, swimming pools, and roofs. We install liquid-applied, sheet-applied, pre-applied, and under-slab membranes along with drainage systems, waterstops, coatings, TPO roofing, and sheet metal flashing.
For new construction, our team can work from project plans and specifications to coordinate waterproofing with concrete, drainage, roofing, and other trades before installation begins.
Waterproofing for Brentwood New Construction
New construction can require waterproofing at several elevations of the same building. A project may have waterproofing beneath the lowest slab, along below-grade walls, around parking areas, across elevated decks, and at the roof.
We work with general contractors, developers, builders, and project teams to identify the specified waterproofing systems and determine when each portion needs to be installed.
This is particularly important for below-grade construction because under-slab membranes, pre-applied waterproofing, waterstops, and other concealed components must be completed before subsequent construction covers them.
Basement and Below Grade Waterproofing
Basements and below-grade structures require a continuous waterproofing barrier between the building and the surrounding soil and moisture.
Depending on the construction method, we install liquid-applied or sheet waterproofing on completed exterior walls, or pre-applied and blindside membranes where the waterproofing must be placed before the permanent wall is constructed.
For structures extending below ground level, under-slab waterproofing can be connected with the wall waterproofing at the slab perimeter to protect areas beneath the building.

New Construction Coordination
We understand when waterproofing needs to occur in relation to reinforcing steel, concrete placement, drainage, penetrations, backfill, and adjacent trades.
Subterranean Parking Waterproofing
Brentwood’s larger residential and mixed-use projects can include one or multiple levels of subterranean parking. Current and proposed projects along Wilshire demonstrate this development pattern, including one-level and multi-level underground garages.
Waterproofing for these structures can involve exterior foundation walls, blindside conditions, under-slab membranes, concrete construction joints, waterstops, penetrations, ramps, and transitions between the garage and the building above.
We coordinate the waterproofing installation with the concrete sequence so concealed membranes and details are completed before access is lost.
Retaining Wall and Foundation Waterproofing
Custom residential construction in Brentwood can include basements, foundations, retaining walls, and significant grading.
For accessible foundation and retaining walls, we can install positive-side waterproofing using liquid-applied or sheet membranes over the prepared wall surface.
Drainage boards direct water along the wall, protection components protect the membrane before backfill, and French drains can collect and redirect water at the base of the structure.
Waterproofing Materials for Below-Grade Construction
The appropriate membrane depends on how the structure is being built and when the waterproofing can be installed.
-
Liquid-applied membranes create a continuous waterproofing layer across prepared concrete and can conform to irregular surfaces and details.
-
Sheet-applied membranes provide a manufactured membrane thickness and are installed with sealed seams, transitions, and terminations.
-
Pre-applied and blindside membranes are installed before the permanent structural wall where conventional exterior access will not exist afterward.
-
Under-slab membranes are installed beneath the building before reinforcing steel and concrete placement.
These systems can be combined with drainage boards, protection components, French drains, primers, sealants, and other compatible materials specified for the project.
Deck and Balcony Waterproofing
Brentwood residences and multifamily properties can include balconies, elevated terraces, walkways, and exterior decks above occupied spaces.
We install multi-layer waterproofing systems using primers, reinforced membranes, waterproof base coats, and durable exterior finish coats.
The installation extends beyond the main deck surface to integrate the membrane with drains, door thresholds, walls, perimeter edges, railing locations, and sheet metal components.
Swimming Pool Waterproofing
We provide swimming pool waterproofing for new construction and renovation projects in Brentwood, including pools incorporated into custom homes, elevated outdoor areas, and larger residential developments.
Our scope can include waterproofing the concrete pool shell, bond beams, raised walls, overflow areas, and adjoining pool decks. We install cementitious and liquid-applied systems based on the specified finish and waterproofing requirements.
For new construction, we coordinate the pool waterproofing with the pool contractor and surrounding construction so our work is completed at the proper stage before finishes are installed.
Waterproofing Plan Review and Submittals
For projects already in design or construction, we can review the waterproofing plans, specifications, wall sections, and details to determine the required scope.
This review helps identify areas such as under-slab waterproofing, below-grade wall membranes, penetrations, drains, transitions, and terminations that need to be coordinated before installation.
When required, we can also provide manufacturer product data and waterproofing submittal information for materials included in our scope.
Roof Deck Waterproofing and TPO Roofing
Brentwood projects can include low-slope roofs, occupied roof decks, rooftop terraces, and other areas where roofing and waterproofing scopes meet.
We install TPO roofing and roof deck waterproofing systems for residential, multifamily, and commercial construction. Our work can include the membrane system, insulation and cover board where specified, as well as sheet metal flashing and waterproofing at roof edges, parapets, drains, curbs, and adjoining walls.
On new construction, we coordinate these areas with the surrounding deck, wall, and sheet metal work to reduce gaps between the roofing and waterproofing scopes.
Brentwood Waterproofing FAQs
What is the best waterproofing system for a basement in Brentwood?
The appropriate system depends on the basement construction, exterior access, drainage conditions, and project specifications. Options can include liquid-applied, sheet-applied, blindside, pre-applied, and under-slab waterproofing systems.
How do you waterproof an exterior foundation wall?
The concrete surface is prepared before the specified liquid-applied or sheet membrane is installed on the exterior side of the foundation wall. Drainage board and membrane protection can then be added before backfill.
Does a retaining wall need waterproofing and drainage?
Waterproofing and drainage perform different functions. The waterproofing membrane protects the wall from water intrusion, while drainage board and French drains help collect and redirect water from behind the retaining wall.
How do you waterproof a below-grade concrete wall?
Below-grade concrete walls can be waterproofed with liquid-applied or sheet membranes installed on the exterior side of the wall. Where exterior access is limited by the construction method, blindside or pre-applied waterproofing may be used instead.
How do you prevent water from entering a basement foundation?
A properly designed system can combine exterior waterproofing membranes with drainage boards, French drains, sealed penetrations, and other waterproofing details to protect the basement from water entering through below-grade walls and foundation areas.
What drainage system should be installed behind a retaining wall?
Depending on the project design, drainage board can be installed against the waterproofed wall to direct water downward, while a French drain at the base collects and redirects the water away from the structure.
What waterproofing is needed for a roof deck over living space?
A roof deck over occupied space requires a waterproofing system designed for exterior exposure and the intended deck use. The membrane must also be properly integrated with drains, walls, thresholds, perimeter edges, and sheet metal flashing.
When should foundation waterproofing be installed on new construction?
Foundation waterproofing is typically installed after the exterior wall is ready to receive the specified system and before drainage components and backfill cover the wall. Under-slab, pre-applied, and blindside systems must be installed earlier in the construction sequence.
Can you review waterproofing plans for a Brentwood development?
Yes. We can review waterproofing plans, specifications, wall sections, and details to identify the required systems and prepare the waterproofing scope.
