Waterproofing is a vital part of every aspect of building design and construction.
Water ingress is the reason for a lot of building envelope failures and can usually require expensive repairs and remedial action.
Waterproof membranes really are a critical portion of residential house and commercial building practices whether you’re wanting to stop water from escaping from your swimming pool or should steer clear of the passage of water into walls and habitable areas.
Waterproofing membranes are generally located 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, featuring its torrential downpours as well as humidity, and also rising sea levels and increasing flooding events signifies that installing adequate waterproofing membranes is essential.
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 and minimize your heating bills too.
Waterproof membranes also play a huge role in restoration and repair projects. Heritage buildings and houses could be at risk from water damage and mold on account of poor design and alterations in ground water levels.
Slumping foundations, damp basements, and mildew are routine signs of a water issue that really needs attention.
There’s a vast range of waterproof membranes available; some are multipurpose whilst other people created for highly specific applications.
BATHROOMS & SHOWERS
Wet areas like 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 risks water ingress with standard acrylic tray and wall showers is important on its own but becomes a lot more important if you wish to purchase a wet area shower.
Even small quantities of moisture can damage some flooring products, specifically the particalboard type, resulting in swelling, popped joints and nails/ screws and ultimately the entire degradation from the material.
A water-proof membrane is essential in wet areas for both floors and walls. Coverings including tiles or vinyl don’t offer an adequate degree of protection alone.
Just a recommended waterproof membrane can provide you with real reassurance.
POOLS & WATER TANKS
Waterproof membranes form an essential role in maintaining a fantastic seal beneath and around swimming pools, water tanks, and sewerage treatment tanks.
Waterproof membranes here must be in a position to withstand the big pressures involved with containing bulk water.
WALL & Roof tiles
It is usually particularly hard to ensure an effective waterproof layer underneath tiles want . good adhesion is needed for screed.
Effective waterproofing is crucial especially where tiles are employed in wet areas because the gaps between tiles makes it possible for easy water ingress.
UV exposure are often an issue as well as for the necessity for a membrane which is suitable for safe h2o.
WALLS
Many cladding types and building designs could be vulnerable to leaks specifically flashing’s and drainage have not been done properly.
This is either way older style and more modern constructions. Whether you’re conducting a new build or repairing a pre-existing leak it’s vital that you make sure the waterproof membrane works and sturdy.
FORMWORK
Waterproof membranes play a vital role as both an obstacle against water penetration along with 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 need the careful use of an efficient waterproof membrane.
This also pertains to balconies, terraces, and planter boxes, which frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are essential here too as with all structure that extends past the building envelope.
Inadequate sealing against moisture penetration with the significant load bearing properties of balconies make water ingress and damage perhaps the most common occurrence.
A water-resistant membrane should cover not only the ground but additionally extend partway up adjoining walls to form an adequate barrier.
FLOORS
Water damage is among the most common and expensive insurance jobs. Water leaks can damage floors over an extended time period prior to the damage becomes obvious.
Effective waterproof membranes are particularly crucial for floors underground (basements and car parks), in wet areas like bathrooms, and underneath pools and spas.
FOUNDATIONS
Foundations and basement areas commonly require some type of waterproof membrane. This runs specifically true for multi-storey buildings, sloping sites, along with older buildings where adequate drainage may not have been designed or included in the web page.
Burst water pipes also can do significant damage underground if basement and foundation level structures are not paid by a water-resistant membrane.
Oftentimes these areas will often be beyond sight, out of 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 levels 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 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 result in weak, crumbling concrete structures which allow water ingress a little more forward into the building envelope.
Such a damage can be quite costly to fix and the installing of a trusted waterproof membrane is critical.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes appear in a range of types designed for different applications and conditions.
Membranes have to be flexible and able to expand and contract when temperature changes make the building surface to go.
What one meets your requirements is determined by several factors. You may have to think about the following aspects:
UV exposure
Kind of substrate
Experience dirt & traffic
Height and width of area to be covered
Internal or external use
Storage of potable water
It’s vital that you choose the right waterproof membrane material for the specific job and discover how to put it on.
Remember, the main causes of waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
