Install appropriate Gutters and downspouts
What most homeowners do not understand is that the biggest barrier system in an American home is the roof, gutters and downspouts. The first thing you should do is check your house roof drainage system cracks, holes or gaps in the seams or lining. You should also check the blockages of leaves, twigs or other debris that can be "dirty works."
Correct soil slope problems
Your soil around your foundation walls should always slope for at least four to five feet using a minimum of 10 degrees or more. This ensures that tread water along the top will not be around and infiltrate your basement. If you want to hire the waterproofing instructor then you can hop over the link.

Installing an external drainage system
This type of sealing system requires that the ground side of the outdoor foundation walls to be removed and a plate or membrane and a drainage pipe installed against the walls. Then, the area can be backfilled with earth, sand or gravel. Considered by many scholars of the American seal as one of the most effective methods for external problems, it also has the most expensive.
Above the internal drainage channel of the concrete floor
In this approach, a drainage channel is installed inside the basement at the base of the foundation wall above the ground. This method does not really solve the problem of infiltration of water, but simply allows the water to be redirected from the bottom of the walls in a floor drain or sump.
