Generally, all homeowners never envision cold and damp concrete floors when thinking of an attractive modern house floors. This is because such floors allow water vapor from the soil to contact the slab, which eventually makes them damp. Water vapor has several side effects that easily destroy the floor, including; discoloring the acid stains, producing efflorescence effect, curling the slab, destroying the overlays, sealers, aggregates, and condensing objects placed on the floor. All these can be prevented with a concrete moisture barrier.
Several constructors hold to the fact concrete vapor sealers are the ultimate remedy to all these issues. This is opted to the fact that barriers are used for, both, controlling soil moisture and actual elimination of vapor from contacting the floor slab. As such, the modern barriers are believed to be the best solution compared to the traditional types.
The ancient barriers still allow vapor to sip through them and reach the slab. Moreover, they cannot perfectly withstand much pressure during slab construction. On the other hand, the new barriers efficiently conform to the requirements of the ASTM E-1745 and completely eliminate vapor.
The ASTM E-1745 specifications are grouped into three categories in order offer very little permeability. This implies that they can effectively ensure that soil vapor does not contact the floor slab. Therefore, most constructors turn to using the sealers to ensure that the slab takes little time to dry up.
It has also been discovered that modern barriers are resistant to damages that may arise when placing the slab. With the aid of the global construction guide, it has been noted that a ten-millimeter barrier can effectively stop the contact between the soil vapor and the slab. However, it is also claimed that such thickness withstands pressure but still permits vapor to reach the slab.
New barrier versions such as raven, fortifiber, and polyguard, among others, have therefore been recommended for their impermeability. To be effective, homeowners are advised to use the ASTM E-1745 guide to appropriately install a sealer during construction. It states that the slab should be placed on top of the sealer such that the sub-base is underneath it.
If the building is closed when placing a dry sub-base, then the sealer should be placed beneath it. Holes should not be bored on the sealer even if there is a lot of water on the slab during construction. When placing it, form stakes should not be pound on it since that can easily lead to damages it. Rather, bearing pads can be used to support it or use a vapor stake to seal it.
A six-inch overlap should be provided when using the moisture beams to seal it all round. In the same manner, all block outs and pipe penetrations need to be sealed using vapor beams. The sealing is extended to the foundation wall with a sealing tape in order to ensure that there is no future damage to the barrier. Nevertheless, constructors are reminded that the slab can only be placed on the concrete moisture barrier when the sub-base is dry and well protected. This also calls for using enough aggregates and reinforcing the lower parts of the concrete slab.
