Modern flat roofings tend to utilize a constant membrane covering which can better resist pools of standing water. These membranes are applied as a constant sheet where possible, though sealants and heat welding is available to allow for bonding multiple sheets and handling structures penetrating the roof surface area and forms a homogenous layer impervious to moisture.

Our Basement Renovation Starts With Long-term Waterproofing

basement waterproofing WoollahraBasement remodeling can add lots of additional living space to your house but beware; basement water leak might put a real damper on your hopes if not appropriately fixed.
There are 2 conditions you should deal with for a dry basement, actual water leak, and condensation. Water leak is a quite apparent issue to property owners but lots of are uninformed 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 outdoors gets in the basement, it shrinks in volume as it cools. This shrinking or “condensing” of the air volume results in higher humidity. Everything porous in your basement will soak up the additional moisture in the air and cause a nasty odor. Dehumidifiers are home appliances which mechanically remove the undesirable additional humidity from your basement. A great dehumidifier is a need to if you intend on remodeling your basement. Even a basement that does not leak will gain from utilizing a dehumidifier.

Water Leakage

Without doubt, water leak into the basement should be completely fixed before you begin your remodeling project. Start by correcting apparent sources of the issue; broken or non-existent gutter, downspouts clearing next to the structure, ground outside sloping toward the house, uncovered underground windows, and so on
. After you exhaust all preventative procedures outside, try to determine areas inside where you are experiencing the leak. If a corner of the basement seems to be a specific issue, once again, look outside at your rain gutter downspouts. If you see fractures in the walls leaking, a few of these can be fixed with hydraulic cement or crack injection. If water seems to be coming in from an isolated area, setting up a sump pump listed below floor level can lower the water table and underground hydrostatic pressure in that area. If you are not sure or your problems appear to be widespread, it might be best to contact a building inspector, engineer or other expert to help you determine and resolve your issue. There are a range of services available to resolve your leak problems. These include; outside excavating, re-parging your walls, interior or outside drainage systems, interior cove systems, grout or epoxy injection and others. The majority of these choices will require an expert.

Basement Renovation Begins

remodelling WoollahraIf you can spare the additional space, 2X6s are even better because they allow space for more insulation. Never ever, under any scenarios, nail furring strips onto the walls. Penetrating the structure will compromise its barrier versus water.
Use building and 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 break and ultimately need to be replaced. Glued down carpeting creates a real issue later on when attempting to eliminate it. Inform your carpet installer to utilize building and construction adhesive to set up the carpet tack strips around the border. Do not allow them to drive nails into the cement floor.


With some sound judgment, building and construction technique, a trusted waterproofing system, and humidity control, and a great waterproofing company like Jacks Waterproofing NSW, you can take pleasure in a great deal of additional living space by remodeling your basement in Woollahra.
