Recent Basement Waterproofing Project

Negative pressure membrane - Barcom Ave Darlinghurst

This basement had moisture pushing through the brick walls. We stripped back the damaged plaster, prepared the masonry, and applied a negative pressure membrane to the inside face of the walls.

We chose this system because the water was coming from outside. A negative pressure membrane is applied on the room side and holds moisture back even when it is still pushing through from behind. That keeps the basement dry without excavating around the outside of the building.
