Basement Waterproofing in South London

Is the basement damp wreaking havoc on your home’s foundation? Protect your basement with the help of South London’s leading waterproofing contractors. We offer certified, guarantee-backed and BS 8102:2022-compliant waterproofing solutions for your property.

Expert Waterproofing Solutions Across South London

Many homes and commercial buildings face ongoing basement damp issues due to age, heavy rainfall, and high water tables. Without proper protection, your basement can quickly become unusable or even unsafe.

Some common waterproofing problems:

  • Crumbling walls and peeling paint from rising damp.
  • Water ingress due to poor external drainage.
  • Musty odours and visible mould patches.
  • Flooded or unusable basement spaces.

Older brickwork and London clay soils make it even harder for moisture to escape. Without modern damp-proofing solutions, South London homes become prone to leaks, condensation, and structural problems.

That’s where we comes in. We’re a local waterproofing company with a track record of guarantee-backed, BS 8102:2022-compliant solutions. Our experts stop the leakage and mould and boost your property’s life. 

Our Waterproofing Services in South London

We provide specialised basement waterproofing for all South London properties, including converted flats, period homes, and terraced houses. Our solutions target common damp, flooding, and water ingress issues.

Basement Waterproofing Systems (Type A, B, and C)

We install Type A, B, and C basement waterproofing systems for your homes. Our systems comply with BS 8102 standards and keep your basement dry year-round.

Cavity Drain Membrane Installation

Cavity drain membranes create a controlled drainage path behind basement walls. We fit these systems to redirect moisture away and protect your interior walls and finishes from dampness.

Sump Pump Installation and Servicing

We fit and maintain high-performance sump pumps in your homes, helping remove excess groundwater quickly, especially in flood-prone zones.

Cementitious Tanking

Most South London homes need tanking systems to create a solid barrier on internal walls and floors. This solution is perfect for older brick properties struggling with water penetration.

Structural Waterproofing for Conversions

We provide structural waterproofing for property conversions. Whether you're converting a cellar or extending below ground, our solutions keep water and dampness out.
