Remediation Schemes

Based on CCL’s longstanding experience, it can Design and Guarantee a Waterproofing Strategy for Remediation Schemes – compliant with BS:8102. This means peace of mind is guaranteed.

Scheme Types


Depending on the project requirements CCL can offer a bespoke design proposal dependant on what form of waterproofing is achievable and appropriate to remediate the existing system or to provide a waterproof solution presented after adaptations/extensions made to the existing structure.

Concrete Repair

Defective, blown, or poor-quality concrete can lead to serious structural defects, and even worse further down the line if it is not rectified. Surface cracking is often one of the first signs, leading to structural cracking and steel reinforcement corrosion. CCL has experience in carrying out concrete repair and protection to a wide range of existing reinforced concrete structures.

Movement Joint

Movement joints are a critical part of the waterproofing design, especially on podium roof decks, where if not detailed correctly can cause considerable damage to area/finish below.  From the numerous projects CCL have completed we have vast experience in installing Movement Joints, including Hypalon Bandages, Sealant Joints and Mechanical Joints.

Injection Systems

CCL’s specialist Injection team can undertake remedial concrete pressure resin Injection, installation of preventive injectable Water bar/stops and chemical DPC injection systems to existing walls, to help protect against rising damp often in historical listed buildings and older structures.

Bunded Structures

CCL has long-standing experience in testing and remediating bunded structures.  It can undertake the preparation, application and certification of the remedial scheme.  Working with some of the leading figures in the construction industry CCL can help to redesign, troubleshoot and execute the correct remediation solution for your project.

Grosvenor House

“Grosvenor House was a complex domestic build located on a site that was very wet. The subterranean ground conditions were running sand and a potential ground water pressure of 5 tonnes per square metre expected to the RC basement structure. With this in mind we needed to have complete confidence in the company who would be providing the water proofing solutions, which we found in CCL. From their initial proposals all the way through to completion they were professional, helpful, thorough and cost effective. It is imperative as a luxury house building company that you have a watertight structure below ground. Due to the CCL solutions and implementation, there have been no such issues that have arisen since completion and that is invaluable.”
