Brush Applied Dpm For Foundations Reveals And Detailing — Intelligent Membranes

Brush-Applied DPM for Foundations, Reveals and Detailing

A damp proof membrane is only as good as its weakest detail. Around foundations, reveals and upstands you need to apply a DPM by hand, accurately, where a sprayed or rolled coat can’t reach cleanly.

Brush-applied DPM on detailing

Where DPMs fail

Rising and ground moisture finds the gaps — around penetrations, at wall-to-floor junctions and on awkward foundation details that a roller skips over. Approved Document C requires continuous resistance to ground moisture, and continuity is exactly what hand-detailing protects.

The solution: Waterproof Blue (5kg Brush)

Waterproof Blue (5kg) is a brush-applied liquid damp proof membrane for detailing foundations, reveals, upstands and junctions. It seals against rising and ground moisture by hand, complementing the larger 10kg roller grade on open floors and walls — one continuous, seamless barrier.

How it is applied

  • Prepare a sound, clean substrate
  • Brush the membrane into junctions, reveals and around penetrations
  • Lap into the rolled DPM on the open areas

Benefits

  • Brush-applied for accurate detailing
  • Seals against rising and ground moisture
  • Seamless, flexible, crack-bridging finish

Frequently asked questions

Do I need both grades? Use the brush grade for details and the roller grade for large areas; together they give full continuity.

Is this for below-ground tanking? For habitable below-ground space follow BS 8102 — see The GOAT.
