Our Basement Remodeling Begins With Irreversible Waterproofing

basement waterproofing Bellevue HillBasement renovation can include lots of extra living space to your home but beware; basement water leakage could put a real damper on your hopes if not properly corrected.
There are two conditions you must resolve for a dry basement, actual water leakage, and condensation. Water leakage is a quite apparent issue to house owners but many are uninformed of the issues that high humidity can trigger to a finished basement.

Humidity Issues

Because a basement is below ground, it will be naturally cooler than the floors above ground. When warmer air from upstairs or outdoors goes into the basement, it shrinks in volume as it cools. This shrinking or “condensing” of the air volume results in greater humidity. Everything porous in your basement will soak up the extra wetness in the air and trigger a nasty smell. Dehumidifiers are devices which mechanically remove the undesirable extra humidity from your basement. A great dehumidifier is a must if you plan on remodeling your basement. Even a basement that does not leak will gain from using a dehumidifier.

Water Leakage

Without doubt, water leakage into the basement must be permanently corrected before you start your renovation project. Start by correcting apparent sources of the problem; broken or non-existent gutter, downspouts clearing beside the foundation, ground outside sloping toward the home, exposed underground windows, etc
. After you exhaust all preventative steps outside, try to identify areas inside where you are experiencing the leakage. If a corner of the basement seems to be a particular problem, once again, look outside at your rain gutter downspouts. If you see fractures in the walls dripping, some of these can be repaired with hydraulic cement or crack injection. If water seems to be can be found in from an isolated area, installing a sump pump below floor level can decrease the water table and underground hydrostatic pressure because area. If you are unsure or your issues seem to be extensive, it may be best to hire a building inspector, engineer or other professional to help you identify and solve your problem. There are a range of services readily available to solve your leakage issues. These consist of; outside excavating, re-parging your walls, interior or exterior drainage systems, interior cove systems, grout or epoxy injection and others. The majority of these alternatives will require a professional.

Usage construction adhesive instead of nails or screws to adhere your bottom wall plate to the floor. It’s ok to nail the upper wall plates into the upper floor joists.
Don’t glue down your basement carpet. Carpet is something that is going to wear and ultimately need to be replaced. Glued down carpeting develops a real problem later on when attempting to eliminate it. Inform your carpet installer to use construction adhesive to set up the carpet tack strips around the border. Do not permit them to drive nails into the cement floor.
