Site preparation involves installation of a plastic membrane to cover your chosen insulation, which will need to be taped and jointed, marking-up of a datum line 1 meter above finished screed level, and installation of an expansion joint around the perimeter of each wall. We will require a continuous strong supply of water on site. Before every project we work at, we will conduct a site visit to discuss the preparation with you. Please also refer to our Site Preparation Checklist and request a copy of our Site Preparation DVD
