CSSW.LONDON is a consultancy covering all aspects relating to basement waterproofing. We’ve had the privilege of working on some major projects and have expanded the services offered along the way.


Structural Waterproofing Design

On a UK construction project incorporating a basement (of any sort) a structural waterproofing specialist should be involved. Getting a specialist waterproofing consultant is best practice and keeps the options open to find the best waterproofing design solution. CSSW.LONDON is completely independent from any manufacturer or installer of waterproofing systems. This helps us provide impartial advice on the most appropriate waterproofing design whilst avoiding unnecessary upselling and enabling competitive tender.

We’ve worked on large and small projects and have a wealth of experience in waterproofing design. The expert witness/defect diagnosis work we carry out helps to inform a robust and reliable waterproofing design.


Structural Waterproofing Design Review

Sometimes the need for a specialist waterproofing consultant is realised too late to change the design. Nevertheless we can help corroborate (or otherwise) waterproofing design.

We’ve completed design reviews on some major, and some difficult projects over recent years to a level of professionalism which we’re proud of.


Defect Diagnosis & Expert Witness

When a basement fails and there is water ingress understanding the design and construction is critical to following an appropriate investigative analysis. We love this aspect of work as it helps to inform design and rule out failures on future developments.

Our Technical Director, Ben Hickman, has multiple degrees and chartered status with the CIOB and has completed a Masters level qualification in expert evidence.
