Advanced Foundation Waterproofing for Below-Grade & Hillside Protection
At Surfacing And Waterproofing, we specialize in below-grade and hillside foundation waterproofing to protect buildings from hydrostatic pressure, soil moisture infiltration, and long-term structural damage. Our waterproofing solutions are tailored for residential, commercial, and hillside foundations, ensuring durability, drainage efficiency, and moisture resistance.
The Importance of Foundation Waterproofing
Foundations are continuously exposed to groundwater, rainwater, hydrostatic pressure, and soil moisture, making proper foundation waterproofing essential for long-term protection. Without an effective waterproofing system, water intrusion can lead to moisture-related damage and compromise the performance of the structure. Surfacing And Waterproofing provides foundation waterproofing systems for residential, commercial, and hillside projects using proven waterproofing membranes, drainage boards, perimeter French drain systems, and other below-grade waterproofing products designed to help protect your foundation.
Our Foundation Waterproofing Process
1. Site Evaluation & Subsurface Water Assessment
Before waterproofing, we conduct a detailed inspection to assess groundwater levels, soil composition, and foundation vulnerability. This allows us to implement the best waterproofing strategy for your building.
2. Application of Waterproofing Membranes
We install high-performance waterproofing membranes that prevent water penetration and resist hydrostatic pressure. Our options include:
Liquid-applied waterproofing membranes – Ideal for complex foundation shapes, creating a monolithic seal.
Sheet-applied membranes – Pre-formed waterproofing sheets for enhanced durability.
Cementitious waterproofing coatings – Rigid, water-resistant barriers for added protection.
3. Drainage Board & Perimeter Drain Installation
To manage groundwater movement and relieve pressure from the foundation walls, we install:
Drainage boards that prevent soil contact with the foundation and promote water redirection.
French drains and perimeter drainage systems that channel excess water away from the structure.
Gravel backfill layers for additional drainage efficiency.
4. Sealants & Expansion Joint Protection
We apply high-performance sealants to expansion joints, cracks, and foundation penetrations, preventing leaks and ensuring long-term flexibility.
5. Backfill & Final Waterproofing Inspection
Once all waterproofing components are installed, we backfill the area with properly compacted soil or gravel, ensuring that drainage elements remain effective. A final inspection confirms full waterproofing system integrity.

What is foundation waterproofing and why is it important in Los Angeles?
Foundation waterproofing is the process of applying protective membranes, drainage systems, and sealants to a building’s foundation to prevent water intrusion, structural damage, and mold growth. Proper foundation waterproofing is essential to protect your property’s structural integrity and value.
What types of waterproofing membranes do you use for foundations?
We use three primary types of waterproofing membranes: liquid-applied membranes (creating a seamless monolithic waterproofing barrier), sheet-applied membranes (providing durable protection for foundation walls), and cementitious waterproofing coatings (providing additional protection in areas exposed to high moisture). Our team recommends the most appropriate waterproofing system based on the project plans and site conditions.
Do you specialize in hillside foundation waterproofing?
Yes! Hillside foundation waterproofing is one of our core specialties. Hillside properties in areas like Bel Air and Pacific Palisades face unique challenges, including soil movement and hydrostatic pressure. Our systems combine waterproofing membranes, perimeter French drain systems, and drainage boards to provide comprehensive protection. For coastal properties, we incorporate corrosion-resistant components where appropriate.
Can you waterproof an existing foundation?
Yes. Existing foundations can often be waterproofed by installing an exterior waterproofing system designed for the project’s conditions. After reviewing the foundation and identifying where water is entering, we determine the most appropriate system to help protect the structure from future water intrusion.
How long does foundation waterproofing last?
A professionally installed foundation waterproofing system is intended to provide long-term protection. Its service life depends on factors such as the waterproofing products used, the quality of the installation, drainage, and surrounding site conditions. Selecting the right system and installing it correctly are key to long-term performance.
