Align levelling rails (e.g. made of iron or aluminium) parallel to one another on the floor. While doing so, calculate a superelevation of approx. 10-12%. Installation cables can be laid loosely on the floor. These are then firmly fixed in place during the compaction process.
Using a straightedge, remove the fill above the levelling rails in the lateral direction(!), pushing it back and forth. Then remove the levelling rails and fill in the resulting grooves.
Spread the MEHA fills using a rake. It is possible that some of the MEHABIT has hardened slightly in the transport bags; however, you can easily crush these lumps.
Compress and smooth the dry fill using a perforated wooden rammer. This fulfils two functions: the granulate chips are aligned horizontally and any air that remains in the insulating layer can escape. For fill heights of up to 80 mm, a single compression process is sufficient (if greater levelling heights are required, the fill is compressed once for approximately every 80 mm). You can now carefully walk on the compressed insulating layer.
Cover the MEHABIT layer with MEHARIPP, or MEHASOL for fill heights of more than 80 mm. Among other things, this also prevents loose granulate chips from entering the groove of the flooring panels when these are being laid.
You can then immediately start with the floating installation of the base plates. Keep a distance of approx. 1.5 from the wall on all sides. To do so, fix wedges to the panels nearest the walls. These wedges must be removed again once the subfloor is completed.
You can then immediately lay parquet, plastic flooring or carpets on these flooring panels. This allows you to create a homely, healthy floor quickly and cleanly.
