Our Basement Renovation Begins With Permanent Waterproofing

basement waterproofing Bondi JunctionBasement renovation 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 effectively fixed.
There are two conditions you need to deal with for a dry basement, actual water leak, and condensation. Water leak is a quite apparent issue to homeowners but many are uninformed of the issues that high humidity can trigger 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 outdoors goes into 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 take in the additional wetness in the air and trigger a nasty smell. Dehumidifiers are devices which mechanically get rid of the unwanted additional humidity from your basement. A good dehumidifier is a need to if you plan on redesigning your basement. Even a basement that doesn’t leakage will gain from utilizing a dehumidifier.

Water Leak

Without doubt, water leak into the basement need to be permanently fixed before you start your renovation project. Start by remedying apparent sources of the issue; broken or non-existent gutter, downspouts clearing beside the structure, ground outside sloping towards the house, uncovered underground windows, etc
. After you tire all preventative procedures outside, try to identify 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 cracks in the walls leaking, some of these can be fixed with hydraulic cement or fracture injection. If water seems to be coming in from an isolated area, setting up a sump pump below floor level can reduce the water level and underground hydrostatic pressure in that area. If you are not sure or your issues seem to be widespread, it might be best to employ a structure inspector, engineer or other professional to assist you identify and resolve your issue. There are a range of services offered to resolve your leak issues. 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 alternatives will need an expert.
