The moisture-induced problems attached to the flooring materials continue to adversely affect the construction industry. This results in a frayed relationship, wasted materials, voided warranties, loss of trust on the contractor and lawsuits. Given below are few options you can opt for if you detect moisture vapour emission in a concrete slab:
The first option is not to install a floor covering
The floor covering industry specifies the maximum vapour transmission rates which are acceptable. Emissions higher than these specified levels would eventually result in failure. A floor surface covering should not be installed if the vapour transmission exceeds the maximum specified tolerance level.
The second option is to remove and replace the floor
If there is high volume of slab vapour transmission, even under normal environmental conditions then that may be because of a failure of the vapour control barrier in the construction. This is a permanent condition and the only way to correct the problem is to remove and replace the concrete slab construction.
The third option can be to use a raised access floor system
A raised floor can be installed if the vapour transmission distribution is too high for the floor covering. It provides a void between the base slab and the floor finish. Vapour control barriers can also then be installed within the void space.
It is very well known that the resources, energy and time you put in your property is reflected in its value. Protecting this investment starts by considering proper installation materials before installing any floor covering.
Out of the above options, raised access floor is the most popular and the best option available. There are many other uses of raised floors like it is possible to have lightning and other structural support with these floors.
