Three Methods to Basement Waterproofing

by admin on February 10, 2012

If you are building a home or renovating an existing one, basement waterproofing is one of the most important home improvement tasks your contractor will be working on. Waterproofing is needed anytime a structure is built at ground level or below ground. Waterproofing and drainage considerations are especially needed in cases where ground water is likely to build up in the soil and raise the water table. Water leaking through wall joints and foundation cracks can cause mold, decay and other moisture related problems. Luckily there are ways to prevent this from happening in your home; these methods include interior sealants, exterior waterproofing and interior water drainage.

Foundation cracks, as well as pipe penetrations are the most common entrances for water into your home. These types of openings can be sealed from the inside of your home by pressure injections of epoxies or urethanes. These interior sealants penetrate the foundation all the way through to the exterior which stops a direct seepage path. The best part of interior sealants is that basement waterproofing specialist guarantee these repairs last from anything from 10 year to lifetime warranties.

Waterproofing a structure from the exterior is the only method the IBC (International Building Code) recognizes as adequate to prevent structural damage caused by water intrusion. Exterior waterproofing prevents water from entering foundation walls therefore preventing the wicking and molding of building materials. This is the best way to stop the problem before it happens.

Although interior water drainage isn’t “technically” waterproofing it is one of the best techniques to prevent and reduce basement water. Most basement waterproofing specialists do consider this to be an effective solution. Interior drainage systems drain underground water from alongside the foundation footers and under your basement floor. These will collect water in a piping system and transfer it to a sump pump which will remove the water from your basement before it does any damage. Make sure that the sump pump is prepared to work in case of a power outage. Power outages often come with thunderstorms, and with that much torrential downpour you want to make sure your water defenses are on and working properly. A proper sump pump, backup sump and/or battery backup sump pump should be installed in a large sump pit with an airtight lid for safety and to keep humidity from seeping through to the basement environment, where it can promote mold growth.
