Waterproofing is a vital part of all aspects of building construction and design.

Water ingress is the reason lots of building envelope failures and can usually require expensive repairs and remedial action.

Waterproof membranes certainly are a critical portion of residential house and commercial building practices whether you’re attempting to stop water from escaping from the pool or should stop the passage of water into walls and habitable areas.

Waterproofing membranes are normally based in 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 and high humidity, as well as rising sea levels and increasing flooding events means that installing adequate waterproofing membranes is essential.

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

Adequate waterproofing layers maintain your buildings safe and dry and lower your heating bills too.

Waterproof membranes also play a vital role in restoration and repair projects. Heritage buildings and homes may be at risk from water damage as a result of poor design and adjustments to ground water levels.

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

You will find there’s huge selection of waterproof membranes available; some are multipurpose whilst other medication is suitable for highly specific applications.

BATHROOMS & SHOWERS

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

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

Even small quantities of moisture may damage some flooring products, specifically the particle board type, resulting in swelling, popped joints and nails/ screws and in the end the entire degradation in the material.

A water-proof membrane is essential in wet areas both for floors and walls. Coverings for example tiles or vinyl do not produce an adequate amount of protection alone.

Just a recommended waterproof membrane can provide real peace of mind.

POOLS & WATER TANKS

Waterproof membranes form an important role to maintain a great seal beneath and around regularly, water tanks, and sewerage treatment tanks.

Waterproof membranes here must be in a position to withstand the big pressures involved in containing large volumes water.

WALL & FLOOR TILES

It may be particularly hard to ensure an efficient waterproof layer underneath tiles just because a good adhesion is necessary for screed.

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

UV exposure may also be a concern and for the requirement for a membrane that is certainly suitable for safe mineral water.

WALLS

Many cladding types and building designs can be at risk of leaks specifically if the flashing’s and drainage have not been done efficiently.

This is for older style and much more modern constructions. Whether you’re conducting a new build or repairing an existing leak it’s important to make sure the waterproof membrane is effective and durable.

FORMWORK

Waterproof membranes play a vital role as both an obstacle 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 with the concrete type have to have the careful putting on an efficient waterproof membrane.

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

BALCONIES & TERRACES

Waterproof membranes are crucial here too just like any structure that extends past the building envelope.

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

A water-resistant membrane will have to cover not merely the bottom but additionally extend partway up adjoining walls to make an acceptable barrier.

FLOORS

Damage from water is probably the most common and expensive insurance jobs. Water leaks can damage floors over a lengthy time frame prior to the damage becomes obvious.

Effective waterproof membranes are particularly crucial for floors underground (basements and car parks), in wet areas such as bathrooms, and underneath pools and spas.

FOUNDATIONS

Foundations and basement areas commonly require some type of waterproof membrane. This is especially true for multi-storey buildings, sloping sites, as well as in older buildings where adequate drainage may not have been designed or that are part of the web page.

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

Most of the time these areas tend to be beyond sight, from 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 development of unhealthy amounts of mould.

CONCRETE

Concrete buildings are surprisingly vulnerable to damage from water, especially modern flat roof designs where water can pool and accelerate the pace 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 can cause weak, crumbling concrete structures that enable water ingress a little more forward into the building envelope.

Such a damage can be very costly to fix so the setting up a trusted waterproof membrane is important.

WATERPROOFING MEMBRANE TYPES

Waterproof membranes are available in an array of types created for different applications and conditions.

Membranes should be flexible and able to expand and contract when temperature changes increase the risk for building surface to maneuver.

What type meets your needs is determined by numerous factors. You may need to look at the following aspects:

UV exposure

Form of substrate

Experience 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 to your specific job and know how to use it.

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