Make A Crawl Space Cover In Concrete Wall

Hold an end of the plastic sheeting against the far end of the first crawl space wall.

Make a crawl space cover in concrete wall.

Spread the plastic the length of the wall pulling it 2 or 3 feet past the wall end to measure the length. To pour a floor 3 thick over a 1500 square foot crawl space floor alone is 14 4 cubic yards of concrete. Permanently seals walls and floors. Proper crawl space insulation also can prevent your crawl space from becoming a moist environment that grows and harbors mold and mildew controlling crawl space temperature and moisture is a dual process that works toward a common goal.

The alternative to pumping concrete is a liner sealing system of the crawl space. The advantages of this solution are many. You might have noticed in the previous pictures that the concrete work for the crawl space was not done with much precision at all. With and with out a vapor barrier.

One of the neat things that the mason bricklayer does is carefully adjust the height of the cinder blocks and bricks with mortar thickness so that the crawl space walls end up exactly level all the way around. In this design a concrete pad called a mud pad is poured on the crawl space floor. This is essentially a concrete barrier meant to help control moisture in the crawl space this is done several ways. Also since concrete does not provide a thermal break a temperature difference between the air and the concrete surface will cause condensation.

A temperate lower area that will keep upper floors warm while your home s foundation remains in sound condition. Concrete is heavy and mixing enough by yourself to cover your entire crawl space floor and walls is out of the question.
