Waterproofing
Structural Waterproofing
Where a below-ground or exposed structure faces genuine hydrostatic pressure (water actively pushing against it), the waterproofing system needs to be specified against that pressure, not against assumptions.
Assessing pressure before specifying a system
Structural waterproofing covers situations beyond typical cellar or basement condensation: a retaining wall holding back saturated ground, a below-ground extension, or a structure with a known high water table. These cases warrant a structural assessment referencing BS 8102, considering ground conditions, structural type and intended use before any system is chosen.
Common signs to look out for
A structure below ground level facing known water table risk
A retaining wall with visible water penetration
New-build or extension work requiring waterproofing design
A previous system that has failed under genuine pressure
Structural cracking accompanied by water ingress
A project requiring building-control sign-off on waterproofing design
How We Help
Our structural waterproofing process
This work is assessed and specified with reference to BS 8102, matched to the structure's actual exposure.
- Assessment of ground conditions and water table risk
- Specification referencing BS 8102 categories of use and protection
- Installation of the appropriate barrier, cavity drainage, or combined system
- Documentation suitable for building-control purposes where required
What our customers say
“An altogether professional service. The survey was detailed and the gentleman carrying it out was clearly experienced with older properties. He also pointed out a couple of maintenance items that were contributing to the issue but didn't require any work from DAMPCORE.”

“Excellent communication from my first phone call onwards. I received sensible advice, a clear explanation of the moisture readings and a proper recommendation rather than being pressured into making a decision there and then.”
