Then scatter concrete block to the desired height. Please be aware that the layer of sand and cement screeds should be only 4-5 cm. Therefore, the rest of the cubic capacity of expanded clay slept.

The layer of expanded clay aligned using a laser level. For ease of movement of the screed using pieces of plywood or OSB-plates.

Then lay out the masonry grid around the perimeter for reinforcement of ties.

Using clamps connect mesh with each other.

Further, around the perimeter of coupler sprinkle a thin layer of cement and water to pour clutch expanded clay. Reserve layer for a day to settle and harden.

Then set the beacons using perlgips.
