Basement waterproofing involves a few things.
Follow this guide to help you get started.
Generally, basement waterproofing will involve halting leaks and seepage, closing cracks and hole when water is flowing in under pressure, fixing cracks and holes before waterproofing, packing a leaking floor joint and waterproofing the flooring and walls following all repairs.
To deal with leaks and seepage, find the major causes, which includes poor construction, ''settling'' of the house and water pressure from surrounding areas accumulating and forcing water through the walls.
Find cracks and moisture that seems to build up in any particular area.
If there are no cracks or holes in the walls, you may employ a waterproofing compound straight onto the walls.
On the other hand, you can fill hairline cracks with a standard waterproofing mix.
Other ways to handle leaks and seepage is by using epoxy and latex cement combinations and mortar.
Once patches and repairs are done, you may start waterproofing the walls and flooring.
You can buy latex or epoxy waterproof solutions for treating basement floors and walls.
Since waterproof mixes will usually not stick to painted walls, you should first get rid of the old paint by wire brushing, sanding or sand-blasting the surface.
Also make sure the surface is completely dry.
Most of the time, a leaking issue in a basement is by the joint at the floor and wall.
If the leaking isn't that much, you may be able to handle it by troweling on a double layer of waterproof coat at the floor joint.
However, if the seepage is quite serious, then you may cut a dovetail joint where the wall and floor meet.
When basement waterproofing, check your state and local codes beforehand.
