Our Basement Improvement Starts With Long-term Waterproofing

basement waterproofing Rose BayBasement remodeling can add lots of additional home to your house but beware; basement water leak could put a real damper on your hopes if not correctly corrected.
There are two conditions you need to attend to for a dry basement, real water leak, and condensation. Water leak is a quite obvious issue to property owners but numerous are unaware of the issues that high humidity can cause to a completed basement.

Humidity Problems

Because a basement is below ground, it will be naturally cooler than the floors above ground. When warmer air from upstairs or outside enters the basement, it diminishes in volume as it cools. This shrinking or “condensing” of the air volume leads to greater humidity. Everything porous in your basement will take in the additional wetness in the air and cause a foul smell. Dehumidifiers are appliances which mechanically remove the unwanted additional humidity from your basement. A great dehumidifier is a need to if you intend on remodeling your basement. Even a basement that doesn’t leak will take advantage of using a dehumidifier.

Water Leak

Without doubt, water leak into the basement need to be completely corrected before you begin your remodeling project. Start by fixing obvious sources of the problem; broken or non-existent gutter, downspouts clearing beside the foundation, ground outside sloping toward the house, exposed underground windows, and so on
. After you tire all preventative measures outside, try to determine areas inside where you are experiencing the leak. If a corner of the basement seems to be a particular problem, once again, look outside at your rain gutter downspouts. If you see cracks in the walls leaking, a few of these can be repaired with hydraulic cement or fracture injection. If water seems to be can be found in from an isolated area, installing a sump pump below floor level can reduce the water level and underground hydrostatic pressure in that area. If you are uncertain or your issues seem to be prevalent, it may be best to employ a structure inspector, engineer or other expert to help you determine and fix your problem. There are a range of services available to fix your leak issues. These include; outside excavating, re-parging your walls, interior or outside drainage systems, interior cove systems, grout or epoxy injection and others. Most of these alternatives will need a professional.

Basement Improvement Begins

remodelling Rose BayIf you can spare the additional space, 2X6s are even much better because they allow space for more insulation. Never, under any scenarios, nail furring strips onto the walls. Penetrating the foundation will compromise its barrier versus water.
Use building and 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.
Do not glue down your basement carpet. Carpet is something that is going to break and eventually need to be changed. Glued down carpeting creates a real problem later on when trying to eliminate it. Tell your carpet installer to utilize building and construction adhesive to set up the carpet tack strips around the perimeter. Do not allow them to drive nails into the cement floor.
