bathroom wet areas Bellevue HillWater penetration through ceramic tiles in bath/shower rooms and other wet areas brought on by leakages, floods, substrate motion, and grout failure can lead to substantial costs and much hassle to all those parties included.

Verandas and terraces can differ in size & construction – this will affect the selection of the waterproof membrane. There are many considerations to take into account including deck movement, differential movement, drainage, waterproofing continuity at expansion joints, drainage outlets, deck finishes and most important what is below the balcony or terrace– automobile parking? Habitable space?

Jack’s waterproofing can provide an ideal product for your needs.

Modern flat roofings tend to use a continuous membrane covering which can better withstand swimming pools of standing water. These membranes are used as a continuous sheet where possible, though sealants and heat welding is readily available to allow for bonding multiple sheets and dealing with structures permeating the roof surface area and forms a homogenous layer impervious to wetness.

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

Our Basement Renovation Begins With Permanent Waterproofing

basement waterproofing Bellevue HillBasement improvement can include lots of extra home to your house but beware; basement water leakage might put a real damper on your hopes if not properly corrected.
There are two conditions you must resolve for a dry basement, actual water leakage, and condensation. Water leakage is a quite apparent issue to house owners but many are uninformed of the problems that high humidity can cause to an ended up 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 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 extra wetness in the air and cause a nasty smell. Dehumidifiers are devices which mechanically get rid of the unwanted extra humidity from your basement. A great dehumidifier is a must if you intend on redesigning your basement. Even a basement that does not leak will gain from using a dehumidifier.

Water Leakage

Without doubt, water leakage into the basement must be permanently corrected before you begin your improvement project. Start by correcting apparent sources of the problem; broken or non-existent gutter, downspouts clearing next to the structure, ground outside sloping toward the house, exposed underground windows, and so on
. After you exhaust all preventative steps outside, try to identify areas inside where you are experiencing the leakage. If a corner of the basement seems to be a particular problem, again, look outside at your rain gutter downspouts. If you see cracks in the walls dripping, some of these can be repaired with hydraulic cement or fracture injection. If water seems to be being available in from a separated area, setting up a sump pump below floor level can decrease the water table and underground hydrostatic pressure because area. If you are unsure or your problems appear to be extensive, it might be best to hire a building inspector, engineer or other professional to help you identify and solve your problem. There are a range of services readily available to solve your leakage problems. These consist of; outside excavating, re-parging your walls, interior or exterior drainage systems, interior cove systems, grout or epoxy injection and others. The majority of these alternatives will need an expert.

Basement Renovation Begins

remodelling Bellevue HillIf you can spare the extra space, 2X6s are even better because they permit space for more insulation. Never ever, under any circumstances, nail furring strips onto the walls. Penetrating the structure will compromise its barrier versus water.
Use construction adhesive instead of 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 wear and ultimately need to be replaced. Glued down carpeting develops a real problem later on when attempting to eliminate it. Inform your carpet installer to use construction adhesive to set up the carpet tack strips around the border. Do not permit them to drive nails into the cement floor.


With some good sense, construction strategy, a dependable waterproofing system, and humidity control, and an excellent waterproofing company like Jacks Waterproofing NSW, you can take pleasure in a lot of extra home by redesigning your basement in Bellevue Hill.
