Basement development is increasingly popular amongst homeowners who are looking to utilize the precious space basements have to offer. A developed and renovated basement increases the overall value of the property, even if the homeowner chooses to not put it to use. Before starting the basement development process, it is very important to ensure that basement is properly waterproofed. The cheapest and most basic form of waterproofing entails the use of wall and floor sealers. For houses where flooding or humidity is not really an issue, simply applying an interior wall sealer should be good enough. Always consult an expert before using interior wall sealers; if the water-table around the house is too high, the pressure will compromise the sealer. A more efficient waterproofing system is to employ a drainage system. Interior drainage systems allow water to accumulate before removing it using sump pumps. This is not a practical option for the renovated basements. If you plan to develop the basement, opt for an exterior drainage system. It may be more expensive than an interior drainage system, but definitely works much better. Polymer compounds applied to the exterior walls repel any moisture and humidity and redirect it away from the house via a drainage system.
