A number of circumstances can cause a wet basement or crawl space. First, it’s important that gutters are clean and downspouts divert water away from the house. Divert any puddling water by extending the downspout at least 10 feet from the house. For best drainage, the land surrounding your house should slope away from the foundation. Problems with subsurface water are generally more serious and will require professional help. The least intrusive solution is to install a sump pump, but when subsurface water is putting pressure on basement walls, it might also be necessary to install a subsurface drainage system.
Putting a sump pump near the foundation wall may help to draw the water away from the area.
Also sealing the foundation with a rubber barrier to insure waterproofing will help.
You will first need to dig around the foundation, so that the concrete in exposed.
Waterproof the entire foundation.
First, stop the water. Pick a solution that keeps the water out for a long period of time.
