Waterproofing is an essential part of every aspect of building design and construction.
Water ingress is the reason a lot of building envelope failures and will usually require expensive repairs and remedial action.
Waterproof membranes certainly are a critical part of residential house and commercial building practices whether you’re trying to stop water from escaping from your pool area or must stop the passage of water into walls and habitable areas.
Waterproofing membranes are typically perfectly located at the following:
Foundations and retaining walls
Bathrooms, wet areas, & pools
External walls, balconies & terraces
Roof decks and plant room floors
Car park docks and lift pits
Australia’s climate, having its torrential downpours and also humidity, in addition to rising sea levels and increasing flooding events implies that installing adequate waterproofing membranes is crucial.
Water ingress can rot timber framing and flooring, rust pipes, crack concrete, undermine foundations that will create dangerous mould problems.
Adequate waterproofing layers maintain your buildings safe and dry minimizing your heating bills too.
Waterproof membranes also play a vital role in restoration and repair projects. Heritage buildings and homes could be at risk from inundating because of poor design and changes in ground water levels.
Slumping foundations, damp basements, and mold are typical warning signs of a water issue that really needs attention.
There exists a huge selection of waterproof membranes available; many are multipurpose whilst other people made for highly specific applications.
BATHROOMS & SHOWERS
Wet areas for example bathrooms, showers and laundries can be quite a real challenge to ensure timber framing & flooring, insulation materials, electrical wiring and internal cladding materials usually are not exposed to damaging water ingress.
The risks water ingress with standard acrylic tray and wall showers is important in its own right but becomes a lot more important if you wish to put in a wet area shower.
Even small amounts of moisture damages some flooring products, in particular the particle board type, bringing about swelling, popped joints and nails/ screws and finally the entire degradation of the material.
A waterproof membrane is vital in wet areas for both floors and walls. Coverings like tiles or vinyl do not provide an adequate amount of protection by themselves.
Simply a recommended waterproof membrane can give you real reassurance.
POOLS & WATER TANKS
Waterproof membranes form an important role in maintaining a great seal beneath and around regularly, water tanks, and sewerage treatment tanks.
Waterproof membranes here need to be capable of withstand the enormous pressures involved with containing bulk of water.
WALL & Ceramic tiles
It could be particularly difficult to ensure an effective waterproof layer underneath tiles because a good adhesion is needed for screed.
Effective waterproofing is vital especially where tiles are employed in wet areas for the reason that gaps between tiles enables easy water ingress.
UV exposure are often a worry and for the requirement for a membrane that’s compatible with safe mineral water.
WALLS
Many cladding types and building designs might be prone to leaks particularly if the flashing’s and drainage have not been done correctly.
This is true for both older style plus more modern constructions. Whether you’re carrying out a new build or repairing a current leak it’s imperative that you ensure that the waterproof membrane works well and durable.
FORMWORK
Waterproof membranes play an important role as both an obstacle against water penetration in addition to providing an acceptable surface for applying all kinds 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 the careful using an effective waterproof membrane.
This too refers to balconies, terraces, and planter boxes, which frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are very important here too as with every structure that extends beyond the building envelope.
Inadequate sealing against moisture penetration combined with significant load bearing properties of balconies make water ingress and damage a typical occurrence.
A water-resistant membrane should cover not only the ground and also extend partway up adjoining walls to make a satisfactory barrier.
FLOORS
Water damage and mold is amongst the most popular and dear insurance jobs. Water leaks can harm floors over a prolonged time period ahead of the damage becomes obvious.
Effective waterproof membranes are particularly critical for floors below ground (basements and car parks), in wet areas including bathrooms, and underneath pools and spas.
FOUNDATIONS
Foundations and basement areas commonly require some sort of waterproof membrane. This is especially valid for multi-storey buildings, sloping sites, and in older buildings where adequate drainage might possibly not have been designed or constructed into the site.
Burst water pipes also can do significant damage underground if basement and foundation level structures aren’t paid by a waterproof membrane.
Most of the time these areas tend to be from sight, away from mind and water seepage could cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, and the development of unhealthy numbers of mould.
CONCRETE
Concrete buildings are surprisingly susceptible to inundating, especially modern flat roof designs where water can pool and accelerate the velocity 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 cause weak, crumbling concrete structures that permit water ingress further to the building envelope.
Such a damage can be very expensive to fix so the installation of the best waterproof membrane is very important.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes can be found in a variety of types designed for different applications and conditions.
Membranes need to be flexible capable to expand and contract when temperature changes make the building surface to go.
What one meets your needs is dependent upon a number of factors. You may want to look at the following aspects:
UV exposure
Type of substrate
Exposure to dirt & traffic
Height and width of location to be covered
Internal or external use
Storage of potable water
It’s imperative that you select the right waterproof membrane material for your specific job and know how to apply it.
Remember, the key reasons for waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
