    Waterproofing is an essential component of every aspect of building construction and designs.

    Water ingress makes up about a large proportion of building envelope failures and definately will usually require expensive repairs and remedial action.

    Waterproof membranes certainly are a critical a part of residential house and commercial building practices whether you’re wanting to stop water from escaping from a swimming pool or have to steer clear of the passage of water into walls and habitable areas.

    Waterproofing membranes are generally perfectly located at the following:

    Foundations and retaining walls

    Bathrooms, wet areas, & pools

    External walls, balconies & terraces

    Roof decks and plant room floors

    Car parking docks and lift pits

    Australia’s climate, having its torrential downpours as well as humidity, along with rising sea levels and increasing flooding events ensures that installing adequate waterproofing membranes is vital.

    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 minimizing your heating bills too.

    Waterproof membranes also play a crucial role in restoration and repair projects. Heritage buildings and homes could possibly be at an increased risk from water damage and mold due to poor design and alterations in ground water levels.

    Slumping foundations, damp basements, and mold are common signs and symptoms of a water issue that has to have attention.

    There’s a vast range of waterproof membranes available; many are multipurpose whilst other people made for highly specific applications.

    BATHROOMS & SHOWERS

    Wet areas like bathrooms, showers and laundries could be a real challenge for ensuring timber framing & flooring, insulation materials, electrical wiring and internal cladding materials are not encountered with damaging water ingress.

    The risks water ingress with standard acrylic tray and wall showers is critical in its own right but becomes more important if you need to purchase a wet area shower.

    Even small quantities of moisture can damage some flooring products, in particular the particle board type, bringing about swelling, popped joints and nails/ screws and eventually the whole degradation of the material.

    A water-proof membrane is crucial in wet areas for both floors and walls. Coverings for example tiles or vinyl usually do not provide an adequate level of protection alone.

    Only a recommended waterproof membrane can provide real reassurance.

    POOLS & WATER TANKS

    Waterproof membranes form a necessary role in maintaining a great seal beneath and around pools, water tanks, and sewerage treatment tanks.

    Waterproof membranes here have to be capable of withstand the big pressures associated with containing large volumes water.

    WALL & Roof tiles

    It may be particularly challenging to ensure a powerful waterproof layer underneath tiles want . good adhesion is needed for screed.

    Effective waterproofing is important especially where tiles are widely-used in wet areas because the gaps between tiles allows easy water ingress.

    UV exposure may also be a problem and then for the requirement of a membrane that is certainly appropriate for safe h2o.

    WALLS

    Many cladding types and building designs might be at risk of leaks particularly if the flashing’s and drainage are not done right.

    This is true both for older style and much more modern constructions. Whether you’re carrying out a new build or repairing a preexisting leak it’s imperative that you make sure the waterproof membrane is effective and sturdy.

    FORMWORK

    Waterproof membranes play a huge role as both a barrier against water penetration along with providing a satisfactory surface for applying all types 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 careful using a highly effective waterproof membrane.

    This refers to balconies, terraces, and planter boxes, all of which frequently cause water ingress problems.

    BALCONIES & TERRACES

    Waterproof membranes are crucial 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 common occurrence.

    A waterproof membrane will likely need to cover not simply the floor and also extend partway up adjoining walls to make an adequate barrier.

    FLOORS

    Damage from water is one of the most common and costly insurance jobs. Water leaks damages floors over a long time frame ahead of 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 kind of waterproof membrane. This is especially true for multi-storey buildings, sloping sites, plus older buildings where adequate drainage might possibly not have been designed or that are part of the site.

    Burst water pipes may also do significant damage below ground if basement and foundation level structures usually are not protected by a water-resistant membrane.

    In many cases these areas in many cases are beyond sight, from mind and water seepage may cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, along with the expansion of unhealthy numbers of mould.

    CONCRETE

    Concrete buildings are surprisingly prone to water damage and mold, especially modern flat roof designs where water can pool and accelerate the rate of structural decay inside the roofing materials.

    Concrete roofing that lacks adequate waterproofing may allow water to infiltrate and corrode the steel reinforcing rods.

    Ultimately, this can result in weak, crumbling concrete structures that allow water ingress further in to the building envelope.

    This sort of damage can be very expensive for fix therefore, the setting up a dependable waterproof membrane is important.

    WATERPROOFING MEMBRANE TYPES

    Waterproof membranes come in a range of types designed for different applications and scenarios.

    Membranes should be flexible capable to expand and contract when temperature changes cause the building surface to move.

    Which is right for you will depend on a number of factors. You might need to look at the following aspects:

    UV exposure

    Form of substrate

    Experience dirt & traffic

    Sized location to be covered

    Internal or external use

    Storage of potable water

    It’s imperative that you select the right waterproof membrane material for the specific job and learn how to use it.

    Remember, the main factors behind waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
