Construction of a private house or villa more oftenaccompanied by the creation of a blind area. What is it and why is it necessary? The blind around the house is a kind of foundation defense. From what? From moisture, of course. Excess water is dangerous because it erodes the ground under the foundation, because of what the latter "sits down". And because of its shrinkage, the whole house shrinks. Most often this is uneven. That's why many houses become squinting and a little crooked with time.
Before making a blind area around the house, it is necessary to take a number of important measures for preparation:
Formwork can serve as a simple board, whichwill be given a form to cover. If the ground shrink, then you can not use a concrete solution for the blind area. It must be mobile. An important condition: the blind area around the house should be tilted. This is necessary in order that rainwater can flow down the slope from the foundation, without seeping into it.
In addition, there is no need to make a bundleblind area and foundation. The fact is that these two objects carry a different load, and therefore do not need a binding. In order to prevent atmospheric precipitation from getting into the air vents of the house, you can make special "fungi" on the stage. They are pipes, closed from above with a special tent. Holes for air circulation, of course, are preserved.
The blind area around the house with paving slab will better fulfill its purpose, if it is done not just under a slope, but also on a mobile basis. It's simple:
Required waterproofingmaterial. Suitable roofing material or a dense oilcloth. Digging a hole under the blind area around the house, you need to lay a layer of clay, tightly ramming. Then a layer of waterproofing. After a small layer of sand that is not trampled. The crushed rock, which will be stacked from above, should not be too shallow, but not very large. After another layer of sand is made. Here it can be slightly damped.
If it is desirable to use the pavementtiles or pavers, it is driven exclusively by a rubber hammer into the sand. No mortar or concrete. The seams between the tiles wake up with dry fine sand.
Such a blind area around the house will protect the foundation notonly from penetration of moisture, but also from cracks in winter. The fact is that this blind area is mobile, and therefore allows moisture to penetrate into itself and go into the ground, in the opposite direction from the house. Moreover, in the off-season the stage does not crack from freezing, thawing, expansion and narrowing of water. She's moving. All that is needed in the spring is to slightly tilt the tile, if it has moved.
