COMPREHENSIVE WATERPROOFING FOR RESIDENTIAL, COMMERCIAL & INDUSTRIAL PROJECTS

WATER-TIGHT RESULTS THAT LAST

From high-rise towers and basements to rooftops, retaining walls, and complex infrastructure, our expert team delivers watertight results that last. Whether repairing active leaks or preventing future damage, we combine cutting-edge technology with proven methods to ensure long-term performance in all UK conditions.

OUR WATERPROOFING SERVICES

1. INJECTABLE WATERPROOFING (SNSEAL PATENTED SYSTEM)

​A non-invasive method of sealing cracks, joints, and porous substrates from within the structure.

 

WHY CHOOSE SNSEAL INJECTABLE WATERPROOFING?
Engineered for Tough Conditions – Injected under high pressure to deeply penetrate cracks, voids, and gaps.

  • WORKS IN WET CONDITIONS – Can be applied in saturated environments, active leaks, and even underwater.

  • NO EXCAVATION REQUIRED – Perfect for occupied spaces or restricted access areas.

  • DEEP PENETRATION – Low-viscosity sealant travels further than traditional foam, resin, or PU injections.

  • FLEXIBLE & DURABLE – Cures to a rubber-like consistency, accommodating natural movement in structures.

  • ANTI-MOULD PROTECTION – High ammonia content prevents mould, fungi, and bacteria growth.


APPLICATIONS

  • Basements and foundations

  • Lift pits and elevator shafts

  • Podiums, rooftops and planter boxes

  • Car parks and ramps

  • Construction and expansion joints

  • Secant piles and retaining walls

  • Underground structures and tunnels

​​​

2. MEMBRANE WATERPROOFING

A surface-applied system that creates a continuous protective barrier against water ingress.


OUR MEMBRANE SYSTEMS
We use premium-grade polyurethane, cementitious, and acrylic membranes, suitable for both new builds and remedial works.


KEY BENEFITS

  • TAILORED SOLUTIONS – Every project begins with a free consultation to ensure the right system for your needs.

  • LONG-TERM PROTECTION – Manufacturer and applicator warranties of up to 15 years.

  • VERSATILE APPLICATIONS – Wet areas, rooftops, planter boxes, retaining walls, and external façades.

  • MANUFACTURER-APPROVED APPLICATORS – Certified installation for maximum performance.
     

WHERE MEMBRANES EXCEL

  • Rooftops and podiums (UV-resistant finishes available)

  • Wet areas (bathrooms, kitchens, laundries)

  • Retaining walls

  • Planter boxes (root-resistant systems)

  • Exposed external façades

 

WHY MEMBRANES FAIL (AND HOW WE PREVENT IT)

  • Poor installation or incorrect membrane selection

  • UV degradation, heavy traffic, or substrate movement

  • Inadequate detailing of drains, penetrations, or tanks

Our experts design and install systems that avoid these pitfalls, ensuring maximum lifespan and performance.

​​

3. COMBINATION WATERPROOFING

Some projects require the strengths of both systems. We provide hybrid solutions, combining SNSeal Injectable Waterproofing with membrane systems for complete protection. This approach is ideal for structures requiring both internal crack/joint sealing and external surface waterproofing.​​
