At the same time it is able to withstand external influences, including static loads. Over the entire period of operation the base is almost does not change its properties and qualities.

haydite specificity comes from the manufacturing process. The basic material - the fine clay, which is subjected to high temperature calcination. As a result, we get a light pellets, which do not pass moisture inside, They are very strong.

It is also worth noting, that depending on the size of the granules is isolated expanded clay sand, gravel or crushed stone. The sand fraction is typically up to 5 mm. The diameter of the gravel - up 40 mm, have a rounded shape, and crushed stone - well before 40 mm, but with the presence of corners.

Then begins the most markup ties. Suffice it from the finished floor line down to measure the thickness of the fill. The resulting points are interconnected. As a result, we get another line, which will be a benchmark for the nomination in a subsequent beacon.

But for the nomination lighthouses screed with expanded clay in the apartment, should remove all the debris and dust from the base. Existing cracks should be sealed. If it does not perform, the strong possibility, to have carried out repeated repair. After wade through the slits may moisture.

On the floor of the piazza is the highest point, which sets the minimum height beacons. Usually they come in 6 mm. At the same time we must not forget about the use levels for.
