Our Basement Renovation Begins With Permanent Waterproofing

basement waterproofing WoollahraBasement improvement can add great deals of additional living space to your house but beware; basement water leak could put a real damper on your hopes if not appropriately remedied.
There are two conditions you need to resolve for a dry basement, actual water leak, and condensation. Water leak is a quite obvious concern to homeowners but many are unaware of the problems that high humidity can cause to a finished basement.

Humidity Issues

Because a basement is listed below ground, it will be naturally cooler than the floors above ground. When warmer air from upstairs or outside enters 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 additional wetness in the air and cause a foul smell. Dehumidifiers are devices which mechanically eliminate the unwanted additional humidity from your basement. An excellent dehumidifier is a must if you intend on renovating your basement. Even a basement that doesn’t leak will gain from utilizing a dehumidifier.

Water Leakage

Without doubt, water leak into the basement need to be permanently remedied before you begin your improvement project. Start by correcting obvious sources of the problem; broken or non-existent rain gutters, downspouts emptying beside the structure, ground outside sloping toward the house, uncovered underground windows, and so on
. After you exhaust all preventative steps outside, attempt to identify areas inside where you are experiencing the leak. If a corner of the basement appears to be a specific problem, once again, look outside at your gutter downspouts. If you see cracks in the walls dripping, some of these can be fixed with hydraulic cement or crack injection. If water appears to be can be found in from an isolated area, setting up a sump pump listed below floor level can lower the water level and underground hydrostatic pressure in that area. If you are not sure or your problems appear to be prevalent, it might be best to contact a building inspector, engineer or other expert to assist you identify and solve your problem. There are a range of services available to solve your leak problems. These include; outside excavating, re-parging your walls, interior or exterior drainage systems, interior cove systems, grout or epoxy injection and others. Most of these choices will require an expert.

Basement Renovation Begins

remodelling WoollahraIf you can spare the additional space, 2X6s are even much better because they allow room for more insulation. Never, under any circumstances, nail furring strips onto the walls. Permeating the structure will compromise its barrier versus water.
Use construction adhesive rather than nails or screws to adhere your bottom wall plate to the floor. It’s okay 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 creates a real problem in the future when trying to eliminate it. Inform your carpet installer to use construction adhesive to set up the carpet tack strips around the boundary. Do not allow them to drive nails into the cement floor.
