Our Basement Renovation Starts With Long-term Waterproofing

basement waterproofing Dover HeightsBasement remodeling can include lots of extra living space to your house but beware; basement water leakage could put a real damper on your hopes if not effectively fixed.
There are two conditions you need to deal with for a dry basement, actual water leakage, and condensation. Water leakage is a quite apparent concern to house owners but many are unaware of the issues that high humidity can cause to a completed 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 gets in 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 absorb the extra wetness in the air and cause a foul odor. Dehumidifiers are home appliances which mechanically eliminate the undesirable extra humidity from your basement. An excellent dehumidifier is a need to if you intend on redesigning your basement. Even a basement that doesn’t leak will gain from utilizing a dehumidifier.

Water Leakage

Without doubt, water leakage into the basement need to be completely fixed before you start your remodeling project. Start by fixing apparent sources of the problem; broken or non-existent rain gutters, downspouts clearing next to the foundation, ground outside sloping towards the house, exposed underground windows, and so on
. After you exhaust all preventative steps outside, attempt to determine areas inside where you are experiencing the leakage. If a corner of the basement appears to be a particular problem, again, look outside at your gutter downspouts. If you see fractures in the walls dripping, a few of these can be repaired with hydraulic cement or crack injection. If water appears to be coming in from a separated area, installing a sump pump below floor level can decrease the water level and underground hydrostatic pressure in that area. If you are unsure or your issues seem to be widespread, it may be best to employ a building inspector, engineer or other professional to assist you determine and fix your problem. There are a range of services available to fix your leakage 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 an expert.

Basement Renovation Begins

remodelling Dover HeightsIf you can spare the extra space, 2X6s are even much better because they enable space for more insulation. Never ever, 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 okay 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 wear and ultimately need to be changed. Glued down carpeting produces a real problem later when attempting to eliminate it. Inform your carpet installer to use building and construction adhesive to set up the carpet tack strips around the border. Do not enable them to drive nails into the cement floor.


With some good sense, building and construction strategy, a reliable waterproofing system, and humidity control, and a great waterproofing company like Jacks Waterproofing NSW, you can delight in a lot of extra living space by redesigning your basement in Dover Heights.
