Waterproofing Contractor Beverly Glen
Surfacing And Waterproofing is a licensed and bonded waterproofing contractor serving Beverly Glen with 25+ years of experience. We provide waterproofing for hillside residences, custom homes, basements, retaining structures, decks, swimming pools, and new construction.
Waterproofing in hillside construction often has to work together with grading and drainage. Below-grade walls can retain soil, lower levels can extend into the slope, and portions of the waterproofing may become inaccessible as concrete and site work progress.
Our work includes liquid-applied and sheet waterproofing membranes, blindside and pre-applied systems, drainage components, waterstops, deck membranes, pool waterproofing, roof systems, and sheet metal flashing.
Hillside Waterproofing and Drainage
Water moving through a hillside needs to be considered together with the waterproofing protecting the structure. Beverly Glen hillside properties can involve grading, drainage, shoring, retaining walls, and below-grade construction, making proper coordination between waterproofing and drainage especially important.
We install waterproofing membranes on basement walls, retaining walls, foundation walls, and other below-grade surfaces exposed to surrounding soil and moisture.
Drainage boards can create a path for water along the outside of the wall, while French drains collect and redirect water at the base. Protection components are installed where required before soil or backfill is placed against the waterproofed surface.
Shoring and Limited-Access Waterproofing
Hillside lots can create construction conditions where the permanent wall cannot be built first and waterproofed afterward.
In these situations, blindside or pre-applied waterproofing can be installed against the shoring before reinforcing steel and the permanent concrete or shotcrete wall are completed. The waterproofing then remains between the shoring condition and the new structure.
This requires the membrane, seams, penetrations, terminations, and connections to adjoining waterproofing to be completed at the correct stage because exterior access may not be available later.

Drainage Integration
We understand the relationship between the waterproofing membrane, drainage boards, protection systems, French drains, and surrounding site drainage.
Basement and Foundation Waterproofing
For basement and foundation walls where exterior access is available, we install positive-side waterproofing directly on the outside of the structure.
The process can include preparing the concrete surface, applying primer where required, installing a liquid-applied or sheet waterproofing membrane, and adding protection and drainage components before backfill.
At the bottom of the structure, the wall waterproofing can connect with footing, slab, drainage, or under-slab conditions according to the project design.
Retaining Wall Waterproofing
Retaining walls require both a waterproofing barrier and a way to manage water behind the wall. Depending on the specified system, we install primer followed by liquid-applied or sheet membrane across the prepared wall surface. Drainage board is then installed outside the waterproofing to direct water toward the drainage system, with membrane protection incorporated where required.
We also coordinate waterproofing around wall penetrations, construction joints, terminations, and transitions to adjacent structures.
Waterproofing Below Slabs and Foundations
Some hillside projects extend waterproofing beneath the building rather than stopping at the exterior walls.
Under-slab membranes are installed before reinforcing steel and concrete placement. The horizontal waterproofing is then connected to the vertical wall waterproofing according to the specified detail.
This creates a continuous waterproofing barrier around the portions of a basement or lower level that are surrounded by soil.
Deck and Balcony Waterproofing
Elevated decks and balconies are common components of hillside homes because they extend usable outdoor space beyond the building footprint.
We install multi-layer waterproofing systems using primers, reinforced liquid-applied membranes, waterproof base coats, and UV-resistant finish coats appropriate for exposed exterior surfaces.
The membrane is integrated with drains, thresholds, walls, deck edges, railing locations, and sheet metal components so the waterproofing continues beyond the center of the deck surface.
Swimming Pool Waterproofing
For concrete swimming pools, the waterproofing membrane is installed across the prepared pool shell before the final pool finish.
Depending on the specified system, installation may include primers, cementitious or liquid-applied waterproofing membranes, multiple coats, reinforcement, and compatible sealants.
We also waterproof surrounding pool areas where decks, walls, planters, or other construction connect with the pool structure.
Roof Waterproofing and TPO Systems
We install waterproofing systems for roof decks and TPO membrane roofing for low-slope roofs.
TPO roofing consists of reinforced thermoplastic membrane sheets installed across the prepared roof assembly. Adjacent sheets are heat-welded together at the seams to form a continuous roofing membrane.
Drains, parapets, curbs, penetrations, edges, and wall connections are completed using compatible TPO accessories and sheet metal flashing.
Waterproofing Coordination Before Concrete and Backfill
On hillside construction, the timing of waterproofing can be as important as the membrane selected.
Shoring waterproofing may need to be installed before the structural wall, under-slab membranes before the slab, waterstops during concrete construction, and exterior basement or retaining-wall waterproofing before drainage and backfill.
We review project plans and waterproofing details to identify these stages and coordinate our scope with the general contractor, concrete contractor, drainage work, plumbing penetrations, and other affected trades.
Beverly Glen Waterproofing FAQs
What waterproofing is needed for a hillside home in Beverly Glen?
The waterproofing scope depends on how the building interacts with the slope. A hillside project may require waterproofing at basement walls, retaining walls, shoring conditions, under-slab areas, decks, pools, and roofs, together with drainage around the below-grade structure.
How do you waterproof a basement wall when there is no exterior access?
Blindside or pre-applied waterproofing can be installed before the permanent concrete or shotcrete wall is constructed. This allows the waterproofing membrane to remain on the exterior side of the completed structural wall even when conventional exterior access is not available.
Does a retaining wall need waterproofing and drainage?
The waterproofing membrane and drainage system perform different functions. The membrane prevents water from entering the structure, while drainage components provide a path for water behind the wall and help direct it away from the structure.
When should retaining wall waterproofing be installed?
For positive-side waterproofing, the membrane is installed after the wall is ready to receive the specified system and before drainage components and backfill cover the exterior surface.
What is the best waterproofing system for a below-grade basement?
The appropriate system depends on the construction method, exterior access, groundwater and drainage conditions, and project specifications. Options may include liquid-applied, sheet-applied, blindside, pre-applied, or under-slab waterproofing systems, along with drainage and protection components.
Can you review waterproofing details before concrete is placed?
Yes. Early review is particularly important for under-slab membranes, blindside waterproofing, waterstops, penetrations, and other components that must be installed or coordinated before concrete placement.
Can you coordinate waterproofing with shoring, concrete, and drainage contractors?
Yes. We coordinate waterproofing with shoring, concrete, drainage, and other adjacent trades so membranes, waterstops, penetrations, drainage components, and transitions are completed at the appropriate stage of construction.
Do you provide waterproofing for new construction in Beverly Glen?
Yes. We work with builders, developers, general contractors, and project teams on new-construction waterproofing including basements, retaining walls, shoring conditions, foundations, decks, swimming pools, and roofs.
