To pour a floor 3 thick over a 1500 square foot crawl space floor alone is 14 4 cubic yards of concrete.
Make a crawl space cover in concrete wall.
And that leads to more mold.
Concrete is heavy and mixing enough by yourself to cover your entire crawl space floor and walls is out of the question.
With and with out a vapor barrier.
Hold an end of the plastic sheeting against the far end of the first crawl space wall.
The advantages of this solution are many.
Also since concrete does not provide a thermal break a temperature difference between the air and the concrete surface will cause condensation.
That is 1 1 2 truckloads from a concrete truck.
In this design a concrete pad called a mud pad is poured on the crawl space floor.
Spread the plastic the length of the wall pulling it 2 or 3 feet past the wall end to measure the length.
This is essentially a concrete barrier meant to help control moisture in the crawl space this is done several ways.
You might have noticed in the previous pictures that the concrete work for the crawl space was not done with much precision at all.
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.
Getting concrete from a truck into your crawl space is a difficult.
The alternative to pumping concrete is a liner sealing system of the crawl space.
