Preparation
Confirm with a structural engineer for the required compressive strength required.

Installation
Lay non-porous rigid board directly onto the levelled ground that will be under the slab, excluding footings and structural beams. Lay separating damp proof membrane (DPM) above the Styrofoam RTM-X, lapping 100mm at joints.
