Waterproofing is central to the part of all aspects of building design and construction.
Water ingress makes up about a large proportion of building envelope failures and will usually require expensive repairs and remedial action.
Waterproof membranes really are a critical portion of residential house and commercial building practices whether you’re looking to stop water from escaping from the pool area or should prevent the passage water into walls and habitable areas.
Waterproofing membranes are usually based in the following:
Foundations and retaining walls
Bathrooms, wet areas, & pools
External walls, balconies & terraces
Roof decks and plant room floors
Carpark docks and lift pits
Australia’s climate, using its torrential downpours as well as humidity, as well as rising sea levels and increasing flooding events means that installing adequate waterproofing membranes is important.
Water ingress can rot timber framing and flooring, rust pipes, crack concrete, undermine foundations that will create dangerous mould problems.
Adequate waterproofing layers maintain buildings safe and dry reducing your heating bills also.
Waterproof membranes also play a huge role in restoration and repair projects. Heritage buildings and houses may be vulnerable from inundating due to poor design and adjustments to ground water levels.
Slumping foundations, damp basements, and mould are routine signs of a water issue that needs attention.
You will find there's vast range of waterproof membranes available; some are multipurpose whilst other medication is made for highly specific applications.
BATHROOMS & SHOWERS
Wet areas for example bathrooms, showers and laundries can be quite a real challenge for ensuring timber framing & flooring, insulation materials, electrical wiring and internal cladding materials are certainly not encountered with damaging water ingress.
The potential risks water ingress with standard acrylic tray and wall showers is critical on its own but becomes even more important if you would like purchase a wet area shower.
Even small quantities of moisture may damage some flooring products, in particular the particalboard type, ultimately causing swelling, popped joints and nails/ screws and eventually the whole degradation with the material.
A water-resistant membrane is vital in wet areas for both floors and walls. Coverings like tiles or vinyl tend not to offer an adequate a higher level protection independently.
Simply a recommended waterproof membrane can present you with real satisfaction.
POOLS & WATER TANKS
Waterproof membranes form an essential role in maintaining a fantastic seal beneath and around pools, water tanks, and sewerage treatment tanks.
Waterproof membranes here should be in a position to withstand the enormous pressures linked to containing large volumes of water.
WALL & Ceramic tiles
It may be particularly challenging to ensure a powerful waterproof layer underneath tiles must be good adhesion is needed for screed.
Effective waterproofing is crucial especially where tiles are widely-used in wet areas for the reason that gaps between tiles enables easy water ingress.
UV exposure are often a concern as well as the need for a membrane that is certainly appropriate for safe mineral water.
WALLS
Many cladding types and building designs can be susceptible to leaks especially if the flashing's and drainage weren't done efficiently.
This is true for both older style plus much more modern constructions. Whether you’re carrying out a new build or repairing an existing leak it’s imperative that you make sure the waterproof membrane is beneficial and durable.
FORMWORK
Waterproof membranes play a crucial role as both an obstacle against water penetration and also providing an adequate surface for applying all kinds of cladding types including Hebel block, SIP panels, Dincel, AFS, brick, block, render, and paint.
ROOF
Modern flat roofs especially in the concrete type require the careful putting on a highly effective waterproof membrane.
This too pertains to balconies, terraces, and planter boxes, which frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are essential here too just like any structure that extends after dark building envelope.
Inadequate sealing against moisture penetration with the significant load bearing properties of balconies make water ingress and damage a standard occurrence.
A waterproof membrane will likely need to cover not just the ground but additionally extend partway up adjoining walls to create an acceptable barrier.
FLOORS
Water damage and mold is one of the most popular and dear insurance jobs. Water leaks damages floors over an extended time frame ahead of the damage becomes obvious.
Effective waterproof membranes are particularly critical for floors underground (basements and car parks), in wet areas for example bathrooms, and underneath pools and spas.
FOUNDATIONS
Foundations and basement areas commonly require some kind of waterproof membrane. This runs specifically true for multi-storey buildings, sloping sites, plus older buildings where adequate drainage may possibly not have been designed or constructed into your website.
Burst water pipes can also do significant damage below ground if basement and foundation level structures usually are not paid by a waterproof membrane.
Oftentimes these areas will often be out of sight, away from mind and water seepage might cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, and the development of unhealthy amounts of mould.
CONCRETE
Concrete buildings are surprisingly vulnerable to water damage, especially modern flat roof designs where water can pool and accelerate the speed of structural decay from 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 which allow water ingress further in to the building envelope.
This kind of damage can be extremely costly to fix and so the installing of a reliable waterproof membrane is important.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes can be found in a variety of types suitable for different applications and scenarios.
Membranes have to be flexible and able to expand and contract when temperature changes make the building surface to maneuver.
Which is right for you is determined by a number of factors. You might need to think about the following aspects:
UV exposure
Kind of substrate
Experience dirt & traffic
Sized location to be covered
Internal or external use
Storage of potable water
It’s vital that you select the right waterproof membrane material on your specific job and understand how to apply it.
Remember, the most important causes of waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
