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

Below-grade and hillside foundations are constantly exposed to groundwater, rainwater runoff, and soil moisture, making them vulnerable to water intrusion, cracks, and structural weakening. Without proper waterproofing, hydrostatic pressure can cause foundation leaks, mold growth, and basement flooding. Our specialized foundation waterproofing systems create a seamless moisture barrier for long-term protection.

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.
