What is crawlspace encapsulation?

Under every house there is a basement or a crawlspace which has wirings or plumbing. It is usually the ignored area of the house. It gets the house up off the ground due to wet areas’ which can cause many health issues and property damage also. Therefore people prefer crawlspace encapsulation in order to stop the crawlspace problems.

Crawlspace encapsulation is a sealing or treatment done to cover the crawlspace’s ceiling, walls and floor with a thick polyethylene sheet. It lowers the energy bills of the house and stops the mold formation and musty odors in the crawlspace.

Limitations of crawlspace encapsulation:-

1) Improper encapsulation

Once encapsulation is done there should not be any issues. If wrong materials are used then there will be problems arising like musty smells in your living due to the moisture still seeping inside areas which were not sealed properly or inferior materials were used. Another problem is that, if the humidifier is running continuously, than it means that the crawlspace is flooding due to improper taping and the space sealing was inaccurate.

2) The cost of encapsulation

The cost of encapsulation varies widely, it depends upon the contractors, materials and size of the space. The average cost ranges between $6,000 to $7,000. The contractors may use cheap quality products and a warranty should always be given to cover installation failure.

3) The maintenance and inspection

Crawlspace consists of wirings and pipes, so whenever plumbers and electricians perform repairing in this space, care should be taken that the vapor barrier does not get damaged. Because the pipeline services near the walls requires the seal to be broken and again replaced.

Crawlspace should be inspected twice a year so that the problems does not get worse if any.

How is the Rat slab done?

A Rat slab is basically a thin layer of concrete poured over the vapor barrier in the crawlspace. The floor is given a sloping shape so that the water is drained directly into the sump-pump hole.
