Waterproofing is central to the element of every aspect of building construction and designs.
Water ingress is the reason a large percentage of building envelope failures and will usually require expensive repairs and remedial action.
Waterproof membranes really are a critical a part of residential house and commercial building practices whether you’re wanting to stop water from escaping coming from a swimming pool or need to avoid the passage water into walls and habitable areas.
Waterproofing membranes are generally found 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 as well as humidity, along with rising sea levels and increasing flooding events signifies that installing adequate waterproofing membranes is vital.
Water ingress can rot timber framing and flooring, rust pipes, crack concrete, undermine foundations and make dangerous mould problems.
Adequate waterproofing layers maintain 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 vulnerable from inundating on account of poor design and alterations in ground water levels.
Slumping foundations, damp basements, and mould are typical warning signs of a water issue that requires attention.
There's a huge selection of waterproof membranes available; some are multipurpose whilst other people are designed for highly specific applications.
BATHROOMS & SHOWERS
Wet areas for example bathrooms, showers and laundries could be a real challenge to ensure timber framing & flooring, insulation materials, electrical wiring and internal cladding materials are not encountered with damaging water ingress.
The hazards of water ingress with standard acrylic tray and wall showers is important in its own right but becomes more important if you need to put in a wet area shower.
Even small amounts of moisture damages some flooring products, in particular the particalboard type, bringing about swelling, popped joints and nails/ screws and eventually the total degradation with the material.
A water-resistant membrane is important in wet areas both for floors and walls. Coverings for example tiles or vinyl do not present an adequate a higher level protection on their own.
Just a recommended waterproof membrane can present you with real reassurance.
POOLS & WATER TANKS
Waterproof membranes form an important role to maintain a fantastic seal beneath and around regularly, water tanks, and sewerage treatment tanks.
Waterproof membranes here have to be in a position to withstand the enormous pressures involved in containing bulk of water.
WALL & FLOOR TILES
It may be particularly hard to ensure a highly effective waterproof layer underneath tiles because a good adhesion is essential for screed.
Effective waterproofing is essential especially where tiles are utilized in wet areas for the reason that gaps between tiles makes it possible for easy water ingress.
UV exposure are often a worry as well as for the necessity for a membrane that's suitable for safe drinking water.
WALLS
Many cladding types and building designs may be prone to leaks particularly if the flashing's and drainage weren't done efficiently.
This really is for older style plus much more modern constructions. Whether you’re performing a new build or repairing an existing leak it’s imperative that you ensure that the waterproof membrane works and sturdy.
FORMWORK
Waterproof membranes play a huge role as both a barrier against water penetration and also providing an acceptable surface for applying various cladding types including Hebel block, SIP panels, Dincel, AFS, brick, block, render, and paint.
ROOF
Modern flat roofs especially from the concrete type require careful using an effective waterproof membrane.
And also this refers to balconies, terraces, and planter boxes, that frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are crucial here too as with every structure that extends beyond the building envelope.
Inadequate sealing against moisture penetration with the significant load bearing properties of balconies make water ingress and damage a typical occurrence.
A waterproof membrane should cover not merely a floor but additionally extend partway up adjoining walls to create an acceptable barrier.
FLOORS
Water damage is one of the most frequent and costly insurance jobs. Water leaks can harm floors over a lengthy period of time prior to 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 type of waterproof membrane. This is especially true for multi-storey buildings, sloping sites, plus older buildings where adequate drainage might not have been designed or built into the website.
Burst water pipes also can do significant damage underground if basement and foundation level structures aren't paid by a water-proof membrane.
Most of the time these areas in many cases are away from sight, out of mind and water seepage might cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, along with the expansion of unhealthy degrees of mould.
CONCRETE
Concrete buildings are surprisingly vunerable to water damage and mold, especially modern flat roof designs where water can pool and accelerate the pace 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 will likely lead to weak, crumbling concrete structures that allow water ingress even more in the building envelope.
This type of damage can be be extremely expensive to fix and the setting up the best waterproof membrane is very important.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes are available in a variety of types designed for different applications and types of conditions.
Membranes need to be flexible capable to expand and contract when temperature changes increase the risk for building surface to advance.
What type fits your needs depends on many factors. You may have to take into account the following aspects:
UV exposure
Sort of substrate
Experience dirt & traffic
Size of location to be covered
Internal or external use
Storage of potable water
It’s crucial that you select the right waterproof membrane material for your specific job and know how to put it to use.
Remember, the key factors behind waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
