Waterproofing is an essential part of all aspects of building design and construction.

Water ingress accounts for a large percentage of building envelope failures and may usually require expensive repairs and remedial action.

Waterproof membranes are a critical section of residential house and commercial building practices whether you’re trying to stop water from escaping from a swimming pool or should steer clear of the passage 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, as well as rising sea levels and increasing flooding events implies that installing adequate waterproofing membranes is important.

Water ingress can rot timber framing and flooring, rust pipes, crack concrete, undermine foundations and build dangerous mould problems.

Adequate waterproofing layers keep the buildings safe and dry reducing your heating bills also.

Waterproof membranes also play a vital role in restoration and repair projects. Heritage buildings and houses may be at risk from inundating because of poor design and changes in ground water levels.

Slumping foundations, damp basements, and mildew are normal indications of a water issue that needs attention.

There's a 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 can be a real challenge to ensure timber framing & flooring, insulation materials, wires and internal cladding materials are certainly not exposed to damaging water ingress.

The risks of water ingress with standard acrylic tray and wall showers is crucial in its own right but becomes a lot more important if you would like use a wet area shower.

Even small quantities of moisture can harm some flooring products, particularly the particalboard type, bringing about swelling, popped joints and nails/ screws and finally the whole degradation in the material.

A water-resistant membrane is crucial in wet areas both for floors and walls. Coverings like tiles or vinyl usually do not provide an adequate degree of protection on their own.

Merely a recommended waterproof membrane can give you real reassurance.

POOLS & WATER TANKS
Waterproof membranes form a vital role to maintain a good seal beneath and around pools, water tanks, and sewerage treatment tanks.

Waterproof membranes here should be in a position to withstand the big pressures associated with containing large volumes water.

WALL & Flooring
It could be particularly tough to ensure a powerful waterproof layer underneath tiles must be good adhesion is needed for screed.

Effective waterproofing is crucial especially where tiles are used in wet areas because the gaps between tiles makes it possible for easy water ingress.

UV exposure can be a worry as well as the need for a membrane which is suitable for safe h2o.

WALLS
Many cladding types and building designs might be at risk of leaks especially if the flashing's and drainage have not been done properly.

This is correct both for older style plus much more modern constructions. Whether you’re doing a new build or repairing an existing leak it’s imperative that you guarantee the waterproof membrane works well and durable.

FORMWORK
Waterproof membranes play an important role as both a barrier against water penetration and also providing an adequate 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 of the concrete type require careful putting on a powerful waterproof membrane.

And also this relates to balconies, terraces, and planter boxes, which frequently cause water ingress problems.

BALCONIES & TERRACES
Waterproof membranes are very important here too as with all structure that extends at night building envelope.

Inadequate sealing against moisture penetration with the significant load bearing properties of balconies make water ingress and damage a common occurrence.

A water-resistant membrane should cover not simply the bottom but in addition extend partway up adjoining walls to create an acceptable barrier.

FLOORS
Water damage and mold is amongst the most popular and dear insurance jobs. Water leaks can damage floors over a long 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 is especially valid for multi-storey buildings, sloping sites, and in older buildings where adequate drainage may not have been designed or built into the web page.

Burst water pipes can also do significant damage underground if basement and foundation level structures are not paid by a water-proof membrane.

Oftentimes these areas tend to be from sight, beyond mind and water seepage can cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, and the expansion of unhealthy levels of mould.

CONCRETE
Concrete buildings are surprisingly vunerable to damage from water, especially modern flat roof designs where water can pool and accelerate the velocity of structural decay in the roofing materials.

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

Ultimately, this may lead to weak, crumbling concrete structures that enable water ingress even further in to the building envelope.

This kind of damage can be quite expensive for fix so the installing the best waterproof membrane is very important.

WATERPROOFING MEMBRANE TYPES

Waterproof membranes can be found in a selection of types designed for different applications and types of conditions.

Membranes have to be flexible capable to expand and contract when temperature changes increase the risk for building surface to go.

What type is right for you is determined by a number of factors. You may want to consider the following aspects:

UV exposure
Kind of substrate
Exposure to dirt & traffic
Height and width of place to be covered
Internal or external use
Storage of potable water
It’s vital that you choose the best waterproof membrane material on your specific job and discover how to put it to use.

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