Waterproofing is central to the part of all aspects of building construction and design.
Water ingress accounts for lots of building envelope failures and can usually require expensive repairs and remedial action.
Waterproof membranes really are a critical part of residential house and commercial building practices whether you’re trying to stop water from escaping from the children’s pool or should avoid the passage of water into walls and habitable areas.
Waterproofing membranes are typically based in the following:
Foundations and retaining walls
Bathrooms, wet areas, & pools
External walls, balconies & terraces
Roof decks and plant room floors
Park your car docks and lift pits
Australia’s climate, with its torrential downpours as well as humidity, as well as rising sea levels and increasing flooding events signifies that installing adequate waterproofing membranes is crucial.
Water ingress can rot timber framing and flooring, rust pipes, crack concrete, undermine foundations and create dangerous mould problems.
Adequate waterproofing layers keep the buildings safe and dry and lower your heating bills as well.
Waterproof membranes also play a huge role in restoration and repair projects. Heritage buildings and houses could possibly be in danger from inundating on account of poor design and alterations in ground water levels.
Slumping foundations, damp basements, and mildew are routine indications of a water issue that requires attention.
You will find there’s huge selection of waterproof membranes available; many are multipurpose whilst others are made for highly specific applications.
BATHROOMS & SHOWERS
Wet areas for example bathrooms, showers and laundries is usually a real challenge to ensure timber framing & flooring, insulation materials, electrical wiring and internal cladding materials usually are not exposed to damaging water ingress.
The hazards water ingress with standard acrylic tray and wall showers is critical on its own but becomes even more important if you wish to install a wet area shower.
Even small quantities of moisture damages some flooring products, in particular the particle board type, bringing about swelling, popped joints and nails/ screws and ultimately the complete degradation with the material.
A water-resistant membrane is vital in wet areas for both floors and walls. Coverings like tiles or vinyl don’t offer an adequate amount of protection independently.
Merely a recommended waterproof membrane can present you with real comfort.
POOLS & WATER TANKS
Waterproof membranes form a necessary role in maintaining a fantastic seal beneath and around pools, water tanks, and sewerage treatment tanks.
Waterproof membranes here must be capable of withstand the enormous pressures associated with containing bulk water.
WALL & FLOOR TILES
It is usually particularly hard to ensure a highly effective waterproof layer underneath tiles because a good adhesion is necessary for screed.
Effective waterproofing is crucial especially where tiles are used in wet areas for the reason that gaps between tiles allows easy water ingress.
UV exposure may also be a concern and for the requirement of a membrane that is certainly compatible with safe mineral water.
WALLS
Many cladding types and building designs can be at risk of leaks specifically if the flashing’s and drainage weren’t done correctly.
This is true for older style plus more modern constructions. Whether you’re doing a new build or repairing a current leak it’s crucial that you ensure the waterproof membrane is effective and sturdy.
FORMWORK
Waterproof membranes play a vital role as both an obstacle against water penetration and also providing an acceptable surface for applying all sorts of cladding types including Hebel block, SIP panels, Dincel, AFS, brick, block, render, and paint.
ROOF
Modern flat roofs especially with the concrete type have to have the careful application of a highly effective waterproof membrane.
This too refers to balconies, terraces, and planter boxes, which frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are necessary here too as with any structure that extends at night building envelope.
Inadequate sealing against moisture penetration combined with the significant load bearing properties of balconies make water ingress and damage a common occurrence.
A water-proof membrane will have to cover not simply the bottom but also extend partway up adjoining walls in order to create a sufficient barrier.
FLOORS
Inundating is amongst the most typical and costly insurance jobs. Water leaks damages floors over a lengthy period of time before the damage becomes obvious.
Effective waterproof membranes are particularly crucial for floors below ground (basements and car parks), in wet areas such as bathrooms, and underneath pools and spas.
FOUNDATIONS
Foundations and basement areas commonly require some form of waterproof membrane. This runs specifically true for multi-storey buildings, sloping sites, plus older buildings where adequate drainage might not have been designed or constructed into the web page.
Burst water pipes also can do significant damage below ground if basement and foundation level structures are certainly not protected by a water-proof membrane.
Oftentimes these areas tend to be from sight, out of mind and water seepage could cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, as well as the increase of unhealthy degrees of mould.
CONCRETE
Concrete buildings are surprisingly prone to water damage, especially modern flat roof designs where water can pool and accelerate the velocity of structural decay within the roofing materials.
Concrete roofing that lacks adequate waterproofing may allow water to infiltrate and corrode the steel reinforcing rods.
Ultimately, this will likely result in weak, crumbling concrete structures that enable water ingress even more into the building envelope.
Such a damage can be be extremely harmful for fix so the installation of a trusted waterproof membrane is crucial.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes can be found in a range of types suitable for different applications and scenarios.
Membranes have to be flexible and able to expand and contract when temperature changes increase the risk for building surface to advance.
Which fits your needs is dependent upon several factors. You may have to take into account the following aspects:
UV exposure
Type of substrate
Experience dirt & traffic
Size of area to be covered
Internal or external use
Storage of potable water
It’s crucial that you choose the right waterproof membrane material to your specific job and understand how to put it on.
Remember, the main reasons behind waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
