Peace of mind guarantees

Cast Contracting Limited (CCL) is one of the UK’s leading national waterproofing and ground gas design/installation specialists. We at CCL pride ourselves on offering the highest level of service and quality assurance from concept, design, and installation, through to post installation, from residential basements through to national landmarks.

CCL was formed in 1997 as a specialist waterproofing and coatings company, working closely with manufacturers such as RIW and GCP. Since its inception, the CCL family has grown into a group of companies including CCL Building Products (supply of specialist high-end building products within the wetroom, bathroom and shower markets), and Wetrooms UK (leading UK wetroom installation specialists). Collectively, they all form CCL Construction Group Ltd.

Over the years Cast Contracting Ltd has built up strong working partnerships with architects, manufacturers and main contractors, who trust our waterproofing, tanking systems and solutions. We have been delivering high quality tanking solutions for projects of all sizes and scope, from residential properties through to large commercial buildings and data centres across London and the UK.

With our commitment to using only the best application systems and the latest product innovations for above and below ground level, we are an approved applicator for the UK’s leading waterproofing, tanking, water management and gas proofing manufacturers, such as RIW, GCP Applied Technologies, Newton Waterproofing, Premcrete, Pudlo, Delta, Sika, Visqueen and Juta.

Our strong relationship with these manufacturers ensures that we are not restricted in the types of systems or products that we specify. We will simply design the most appropriate tanking or gas proofing solution for you and your project.

As the leading waterproofing and gas proof membrane contractor, we at CCL can offer a range of different material types including Type A barrier membranes and Type C cavity drain membrane protection. The material used and the type of protection required is entirely dependent on the site conditions and which grade of waterproofing is required to meet the desired performance specification.

As standard, we will work with the project designers and engineers to ensure the Type B is suitably specified and works correctly with the Type A or C systems, or both in some instances.

  • External waterproofing
  • Cavity drainage systems
  • Sump pump installation
  • Bunded tanking
  • Ground gas membranes
  • Podium/Deck waterproofing
