The insulating foundation for energy efficient buildings
If you want to save energy in the future, you must literally start from the bottom up, since thermal insulation always begins at the foundation.
Construction process
A base layer of grit (e.g. 4/8) is applied over the capillary-barrier layer of frost-proof material. The formation level provides a clean basis for the modules of ISOQUICK The Insulated Raft.
The edge modules, which are custom manufactured specifically for each site and are first connected and then aligned with the batter boards.
The edge modules are assembled according to the supplied ISOQUICK installation plan. The dovetail locking system ensures a secure connection during installation and concreting work.
The last edge module fits perfectly into place!
The thermally insulating boarding provided by the ISOQUICK edge modules is soon installed. It is then aligned again with the batter boards and checked by measuring the diagonals.
The edge are completly installed and work as dead sheathing
The base modules and the top modules are now put in place. Continuous joints are avoided by covering the edge modules with top modules and by using an offset installation pattern.
Installation can now proceed row-by-row. The offcuts from one row are used to start the next row, thus reducing waste to a minimum.
The intelligent profile pattern system ensures that the individual modules are tightly positioned and that no sliding takes place during installation and concreting work.
Cutting guides are moulded on the smooth sides of the modules to make cutting easier inside the grid. The modules can be easily cut using a hot wire cutter.
Where pipes run through the thermal insulation holes are sawn out or drilled out, as shown here. The hole can be closed again using construction foam.
ISOQUICK The Insulated Raft is completed and ready for reinforcement and concrete.
A minimal amount of waste offcuts arises for an ISOQUICK The Insulated Raft of around 150 m², if the offset installation pattern is strictly adhered to.
Not a problem! As usual, the edge modules are precut at the appropriate angle.
A row of base and top modules is laid at right angles to the edge modules. The remaining modules are installed in an offset pattern along the row.
A standard DPM (or radon barrier if required) is installed and the required reinforcements installed in ISOQUICK The Insulated Raft.
Concrete can be poured into the ISOQUICK The Insulated Raft using a concrete pump or a crane, as shown here, without need for further shuttering.
The concrete is then finished in the usual manner.
