Foundation Waterproofing
At Liquid Applied Waterproofing Ltd, we provide professional foundation waterproofing services throughout Hounslow, London and the surrounding areas, delivering long-term protection for the most crucial structural element of any building.
Foundations are constantly exposed to groundwater, moisture and soil pressure, making them highly vulnerable to water ingress, dampness and structural deterioration if left unprotected.
Foundations sit below ground level and are therefore subject to continuous environmental pressures, including hydrostatic water pressure, seasonal moisture changes, and ground movement.
Without a reliable waterproofing system, this can lead to cracking, internal damp, structural weakening, mould, frost damage and long-term instability. Our specialists use advanced liquid-applied waterproofing systems designed to create a seamless, flexible barrier that adheres directly to the substrate and prevents water from penetrating into the structure.
Liquid waterproofing is perfectly suited to foundation protection due to its ability to form a fully bonded, joint-free membrane that covers every detail, including corners, edges, construction joints and service penetrations. Unlike sheet-based materials, liquid systems eliminate overlaps and seams—removing the most common failure points. Once cured, the coating provides robust weather resistance, excellent crack-bridging properties and long-term durability against moisture and soil pressure.
We use high-performance waterproofing systems that include flexible membranes, root-resistant coatings, vapour-resistant barriers, protective layers for backfilled areas and reinforced solutions suitable for high-stress environments.
These systems are engineered to withstand constant exposure to soil moisture, fluctuating temperatures and hydrostatic pressures.

FAQs
Why is foundation waterproofing important?
Foundations are constantly exposed to moisture, groundwater and soil pressure. Without waterproofing, water can seep into the structure, leading to cracks, dampness, mould growth and long-term structural damage. Waterproofing protects the building from these risks.
What waterproofing system do you use for foundations?
We use liquid-applied membranes that create a seamless, flexible and fully bonded barrier. These systems are ideal for below-ground structures because they resist ground pressure, movement and continuous moisture contact.
Is foundation waterproofing required for new builds?
Yes. Building regulations and best practice guidance strongly recommend waterproofing for all below-ground structures to prevent future issues and maintain structural integrity.
Do you work on commercial foundations?
Absolutely. We work on foundations for warehouses, retail buildings, offices, schools, public buildings, residential developments and more.
