One of the major considerations while hiring basement waterproofing or crawl space waterproofing contractors is the technology used by the contractors for waterproofing. Some waterproofing contractors use invasive methods which can be time consuming and the structure may have to be vacated while the waterproofing is being done. In other cases, toxic chemicals may be used for waterproofing and the structure may have to be kept empty till the effect of these toxins wears off. After some time, cracks and gaps are formed in the flooring and walls of the basement, and the waterproofing contractor should seal these cracks properly. Compared to other parts of the building which are surrounded by air at atmospheric pressure, the pressure on the basement floor is much more and it is more likely to be damaged. The offer from the waterproofing contractor should specify how the material used will withstand these adverse conditions. The crawl space waterproofing contractor should use fungicides which prevent the growth of fungus, mildew and molds. |
