Installation Processs of the EVG-3D Construction System - 8 Steps from start to finish Step 1 - Connection to foundation The EVG-3D construction systems can be built on any foundation, subject to starter bars cast into the foundation according to structural engineering requirements. The panels are usually placed so that the rebar is set between the mesh and the polystyrene. This ensures easy and precise wall alignment. A damp proof layer is applied under the wall panel. This is white text Step 2 - Erection of wall panels Erection of the EVG-3D panels always starts at corners, in order to achieve the required construction rigidity. Individual panels are connected together using a splice mesh on both sides, using either a manual or a pneumatic fastening tool.
