Leca® Insulation Fill
is a special type of clay that has been pelletised and fired in a
rotary kiln at a very high temperature. As it is fired, the organic
compounds in the clay burn off forcing the pellets to expand and
become honeycombed inside and smooth on the outside.
The resulting ceramic pellets are lightweight, free draining,
insulating and have a high crushing resistance. Bagged Leca® is
ideal for backfill and insulation in poured concrete
How to use Leca®:
Use loose material to level the sub floor and then lay the bags
Continue to lay bags side by side to cover the total floor area.
If a second layer is needed lay these in a brick bond pattern.
Once at the required depth, use loose Leca® to fill holes
between bags and level off.
Lay a 1200 gauge membrane over the insulation fill. The
insulated floor is ready to received the concrete slab.
