Our Basement Renovation Begins With Irreversible Waterproofing

basement waterproofing SydneyBasement remodeling can include great deals of extra living space to your house but beware; basement water leakage could put a real damper on your hopes if not properly remedied.
There are 2 conditions you need to resolve for a dry basement, actual water leakage, and condensation. Water leakage is a quite obvious issue to house owners but many are unaware of the problems that high humidity can cause 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 enters the basement, it diminishes in volume as it cools. This shrinking or “condensing” of the air volume leads to greater humidity. Everything permeable in your basement will absorb the extra wetness in the air and cause a nasty smell. Dehumidifiers are home appliances which mechanically remove the unwanted extra humidity from your basement. A great dehumidifier is a need to if you plan on renovating your basement. Even a basement that doesn’t leak will take advantage of using a dehumidifier.

Water Leakage

Without doubt, water leakage into the basement need to be permanently remedied before you start your remodeling project. Start by fixing obvious sources of the problem; broken or non-existent gutter, downspouts clearing beside the structure, ground outside sloping toward the house, exposed underground windows, and so on
. After you tire all preventative steps outside, try to determine areas inside where you are experiencing the leakage. If a corner of the basement appears to be a specific 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 fracture injection. If water appears to be coming in from an isolated area, installing a sump pump below floor level can decrease the water table and underground hydrostatic pressure in that area. If you are unsure or your problems appear to be extensive, it might be best to employ a structure inspector, engineer or other expert to assist you determine and resolve your problem. There are a variety of services readily available to resolve your leakage problems. These consist of; outside excavating, re-parging your walls, interior or exterior drain systems, interior cove systems, grout or epoxy injection and others. Most of these options will require an expert.

Basement Renovation Starts

remodelling SydneyIf you can spare the extra space, 2X6s are even better because they allow room for more insulation. Never ever, under any circumstances, nail furring strips onto the walls. Permeating the structure will compromise its barrier versus water.
Usage construction adhesive rather than 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 break and eventually need to be changed. Glued down carpets creates a real problem later on when attempting to eliminate it. Tell your carpet installer to use construction adhesive to set up the carpet tack strips around the perimeter. Do not allow them to drive nails into the cement floor.
