A poured foundation is by far the best foundation offering the best structure. Typical problems can be cracks in the foundation. These cracks normally appear off windows, around the beam pocket, and in the corners of the basement which allow water seepage. Water can also enter the basement where the floor and the wall meet.
This is commonly referred to as the Cove. It is very important to determine what types of water you are dealing with, surface water or ground saturation. This will help in understanding if there is a major problem or this is a minor fix. One way of determining the type of water you are dealing with is if comes in immediately it is a surface water problem. Normally this is indicated by the water leaking high on the wall. The biggest contributors to water leaking high on the wall is gutter cascading, down spouts and a negative grad which allows the water to flow back towards the foundation. Ground saturation problem is indicated by seepage where the floor and the wall meet. This can also come in through cracks low on the wall. This normally happens after several days of rain when the ground is saturated. Leaking can continue hours or days after the rain as subsided. It is very important to determine what type of water you are dealing with during an inspection so we can determine the proper solution to your specific problem. It is very important to have a waterproofing expert evaluate your unique and individual problem. The water issue may be as simple as a removing the water (redirecting the flow from the downspout).
