Waterproofing / New Build..
New Build Waterproofing.
LSE take the risk out of new build waterproofing for Architects
engineer’s, contractors and homeowners
LSE design, supply and install waterproofing systems to comply with
BS8102. All designs are covered by our Professional Indemnity insurance
and all installations are covered by our products insurance and long
term insured guarantees.
Not all guarantees are equal. LSE are one of the very few companies who
can offer genuine insured guarantees for waterproofing that covers
labour and materials. We are FSA registered Agents for the GPI insurance
so you know that unlike most waterproofing companies we have been
properly vetted and offer genuine insured guarantee. See our page on
insurance for full details.
LSE specialise in the technically challenging constructions which call
on our very many years of experience.

Installation is carried out by our teams of dedicated qualified Fully
employed (No sub-contractors) installers.
We carry out type “A” Tanking & “C” cavity drainage waterproofing using Newton Membranes Delta Membranes and Grace Products, Fosroc and Vandex systems.
For new build basements we favour the cavity drain membrane system
with drainage, sumps and pumps.
The system is completely reliable and is guaranteed for 10 years.
After which time the guarantee can be renewed for a further 10 years
if required.
The system has a great many advantages over all other water proofing
systems. It is also normally less expensive.
