Once the foundations are poured and the inside skin of blockwork completed to DPM level, (less the thickness of the slab), the face brickwork can be brought up to or past DPM to act as an outside edge shutter. The services can be installed and the oversite firmly compacted to 200mm below the bottom of the slab level.

Installation of the Thermaflor™ now takes place in the following manner:-



1. Working from the inside face of blockwork. Take an Edge Block module, saw it in half and place the cut edge into the corner of the blockwork.

Place Edge Block Module’s along the face of blockwork until the next corner is reached. At this point taking the off-cut block from the first placing, cut to fit tightly (15mm oversize) into corner. Repeat the operation, this time cutting a new Edge Block module to fit squarely against the Edge Block already laid, into corner.

There will now be a continuous row of Edge Block modules forming insulation around the inside face of blockwork.




2. Place a Thermaflor™ raft unit into each corner with the overlap ledges sitting squarely onto the Edge Block modules previously installed.

Place further raft units from each corner towards the centre of the proposed slab. If they do not meet exactly, cut to suit as before (Thermaflor™ has a unique edge and lap profile allowing easy, quick and accurate placing without the need of skilled labour or plant associated with other methods).

Once all raft units are installed, there will remain a cruciform gutter. These are infilled using the infill panels provided, cutting to suit as previously.



3. The future slab now has a continuous layer of insulation as well as a permanent shutter on which to pour the concrete. Insulation can now be placed into the wall cavity at a level which is above the proposed slab upper surface. The DPM or other membranes may be laid (to specification) directly onto the Thermaflor™. Then mesh can be placed on suitable spacers ready for concreting.
