Service

Waterproofing

Basements live or die on the waterproofing detail. We specify and install systems that match the site, not the order book.

We work with both Type A (external/structural waterproofing) and Type C (internal cavity drain) systems depending on the build, the water table and the eventual use of the space.

Detailing matters more than the brand of membrane. Day-joints, kicker joints, service penetrations and floor-to-wall junctions are where most basements leak. We treat each one as a designed detail, not an afterthought.

All our waterproofing installs come with the manufacturer's system warranty and a Wentworth workmanship guarantee.
