Terraces and balconies can differ in size & building – this will influence the selection of the waterproof membrane.

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

Spalling also called Concrete Cancer is a result of water entering brick, concrete or natural stone and requiring the surface to peel, pop out or flake off. This is because there is salt in water. Salt pushes outward from the inside. Eventually, spalling can cause crumbling and damage of a structure.

Our Basement Improvement Begins With Irreversible Waterproofing

basement waterproofing CoogeeBasement improvement 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 correctly remedied.
There are two conditions you should address for a dry basement, real water leakage, and condensation. Water leakage is a quite obvious issue to house owners but many are uninformed of the issues that high humidity can cause 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 enters the basement, it diminishes 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 moisture in the air and cause a nasty smell. Dehumidifiers are appliances which mechanically get rid of the unwanted extra humidity from your basement. A good dehumidifier is a should if you intend on redesigning your basement. Even a basement that does not leak will benefit from using a dehumidifier.

Water Leakage

Without doubt, water leakage into the basement should be completely remedied before you start your improvement project. Start by fixing obvious sources of the issue; broken or non-existent gutter, downspouts emptying next to the structure, ground outside sloping toward the house, uncovered 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 seems to be a specific issue, once again, look outside at your gutter downspouts. If you see fractures in the walls leaking, some of these can be repaired with hydraulic cement or fracture injection. If water seems to be coming in from a separated area, setting up a sump pump below floor level can lower the water table and underground hydrostatic pressure in that area. If you are not sure or your issues appear to be widespread, it may be best to employ a building inspector, engineer or other expert to help you determine and solve your issue. There are a range of services offered to solve your leakage issues. These consist of; outside excavating, re-parging your walls, interior or exterior drainage systems, interior cove systems, grout or epoxy injection and others. Most of these alternatives will need a professional.

Basement Improvement Begins

remodelling CoogeeIf you can spare the extra space, 2X6s are even much better because they allow room for more insulation. Never ever, under any circumstances, nail furring strips onto the walls. Penetrating the structure will compromise its barrier against water.
Use building 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 out and eventually need to be replaced. Glued down carpets creates a real issue later on when attempting to eliminate it. Tell your carpet installer to utilize building adhesive to install the carpet tack strips around the border. Do not allow them to drive nails into the cement floor.


With some sound judgment, building technique, a dependable waterproofing system, and humidity control, and a great waterproofing company like Jacks Waterproofing NSW, you can enjoy a lot of extra living space by redesigning your basement in Coogee.
