To ensure that the building's foundation, which is the base on to which a construction lies on, does not develop cracks, which might lead to the cause of the collapse of the construction, foundation waterproofing needs to be done well. This waterproofing of the foundation is actually a requirement for each and every construction. This involves the attachment or application of a material or composition for waterproofing that ensures a total seamless closure of any passages or holes for water to go through. The foundation itself must be free from cracks, be able to withstand the water sprayed onto the foundation under high pressure and be able to prevent water from seeping through the bottom side of the foundation to make sure that the waterproofing has been a success. The common methods are used for waterproofing and to make sure that the foundation remains dry and free from cracks. Various methods of waterproofing of a construction's foundation have been suggested by professional civil engineers and construction workers because it is very difficult and complicated to ensure that a construction is able to prevent water from seeping in through the foundation.

The first way to do foundation waterproofing is through exterior waterproofing. This involves the insertion or the attachment of a drain tile that is covered with a silt sock on the exterior side of the foundation. After which, a concrete plaster is covered to the foundation. Interior waterproofing is the opposite of this method of waterproofing.

The use of drain tile system incorporated on the inside of the foundation is what the interior waterproofing is all about. Foundation waterproofing is secured by the drain tile's ability to collect the water and lead it to the sump pump. This pump will then lead all the possible water out ultimately. When installing these very sensitive drain tiles, it should be handled with great care to guarantee that they do not affect the foundation in any way as it is, which may negate the reason for waterproofing of the foundation in the first place. It is very important that this is secured because this may lead to the collapse of the construction if not done and completed the right way.
