Retaining Wall Waterproofing
At Liquid Applied Waterproofing Ltd, we provide specialist retaining wall waterproofing services across Hounslow, London and the surrounding areas, delivering robust and long-lasting protection for structures built to hold back soil and withstand continuous ground pressure.
Retaining walls are highly vulnerable to moisture intrusion due to constant contact with earth, groundwater and variable weather conditions.
Retaining walls face a unique set of challenges. As they sit below or partially below ground, they are exposed to hydrostatic pressure, water build-up and moisture migration.
Without a reliable waterproofing system, water can penetrate the structure, leading to damp patches, internal leaks, concrete deterioration, frost damage, cracking, and even structural failure. Our team specialises in liquid-applied waterproofing membranes that create a strong, flexible, fully bonded barrier, preventing water ingress and preserving the integrity of the wall.
Liquid waterproofing is ideal for retaining walls because it forms a seamless coating that adheres to all contours, edges, joints and irregularities. Unlike sheet-based systems, liquid membranes eliminate vulnerable overlaps, cuts and seams—ensuring continuous protection even in areas where detailing is complex. Once cured, the membrane provides exceptional resistance to moisture, soil movement, freeze-thaw cycles and ground pressure.
Our systems include root-resistant coatings, flexible membranes designed to bridge cracks, solutions compatible with drainage boards, and protective layers suitable for backfilling.
These waterproofing systems are engineered to maintain performance under constant load, moisture contact and varying ground conditions.

FAQs
Why do retaining walls need waterproofing?
Retaining walls are in constant contact with soil and moisture. Without waterproofing, water can penetrate the structure, causing dampness, cracks, concrete deterioration and long-term structural issues. Waterproofing is essential to protect the wall and the spaces behind it.
What waterproofing system do you use for retaining walls?
We use liquid-applied waterproofing membranes that form a seamless, flexible and long-lasting protective layer. These systems are ideal for retaining walls because they resist cracking, ground pressure and water ingress.
Do you waterproof new retaining walls and existing ones?
Yes. We provide waterproofing for both new construction projects and older retaining walls that require repair or additional protection.
Do you work on large commercial retaining walls?
Absolutely. We have extensive experience working on commercial developments, infrastructure projects, residential schemes and public sector properties.
