People often think of having the basement worked when they do notice moisture accumulating at the bottom of the basement floor. But for all practical purposes, the moisture ingress into the basement can be classified as three separate causes. The internal, the external and the drainage. It is when the issue is addressed in the right approach that the complete ingress of moisture and water into the basement gets to be controlled.
The internal drainage
By the very term, internal drainage, it signifies the seepage of water from sources that have their input from the interior of the houses or buildings. The first step is to find out the major flow source of the water and to try and block the path of the flow of water as best as possible. This can be affected by putty filling the cracks and to seal in the cracks with sealants for the most parts.
The final result must be that the basement floor must be free of moisture ingress from the interior of the house at anytime. Considering the complexity of the situation, it is never that the process of identifying the internal sources of water is going to be easy but most of the time it is a long drawn out process that needs time spend and effort expended.
At the first instance of keeping out external sources of water, the basement walls are coated with a waterproof compound so as to prevent the water from getting into the basement. This can be approached in two ways. The first is to apply sealant to the interior walls of the basement to keep out the water and the second is to remove the soil around the bottom of the building and to apply a sealant to the external surfaces.
The actual method of application depends on the situation of the repair work and never can be taken to be a rule as such. It is the thorough application of the sealant that decides how effective it is when it comes to keeping out the water.
The basement normally forms the lowest part of any construction. Thus the final resting place or collection point of all drainage in a building gets to be the basement too. If there is a faulty design of drain pipes or of systems to contain the water within, then it would be reflected in the moisture or water ingress into the basement of the buildings.
With this sort of persistent drainage problem, the corrective step is to redo the drains from the scratch. The extra cost would be borne by years of trouble free service hence forth. The thing with piece meal approach is that often sections would not match to each other and water would seep through the different joints that are thus formed at the pipes.
One of the features of drainage or seepage that has not been handled here has been that of condensate being formed on the walls, both the exterior and the interior as well. This effect must be taken into consideration when an actual basement work is being carried out.
