Floor Preparation

Before we lay any pipe or pour screed, we make sure the prep is spot-on.

We handle:

  • 🔹 100mm insulation board installation (e.g. Celotex, Kingspan, PIR)

  • 🔹 DPM (moisture barrier) membrane fitting

  • 🔹 Edge insulation around perimeter

  • 🔹 Sealing & taping for airtight screed prep

Proper prep ensures long-lasting performance and a flawless screed finish.
