Important Information On Waterproofing Membrane

Posted by Cristian Maldonadon on January 17th, 2023

Waterproofing is the central part of all aspects of building design and construction.
Water ingress is the reason for a large proportion of building envelope failures and can usually require expensive repairs and remedial action.
Waterproof membranes certainly are a critical a part of residential house and commercial building practices whether you’re trying to stop water from escaping from the pool or have to avoid the passage water into walls and habitable areas.
Waterproofing membranes are usually located in the following:
Foundations and retaining walls
Bathrooms, wet areas, & pools
External walls, balconies & terraces
Roof decks and plant room floors
Park your car docks and lift pits
Australia’s climate, using its torrential downpours and also humidity, as well as 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 and create dangerous mould problems.
Adequate waterproofing layers maintain buildings safe and dry and minimize your heating bills also.
Waterproof membranes also play an important role in restoration and repair projects. Heritage buildings and homes may be in danger from damage from water because of poor design and modifications in ground water levels.
Slumping foundations, damp basements, and mould are common warning signs of a water issue that has to have attention.
There exists a vast range of waterproof membranes available; many are multipurpose whilst other people created for highly specific applications.
BATHROOMS & SHOWERS
Wet areas including bathrooms, showers and laundries is usually a real challenge to ensure timber framing & flooring, insulation materials, electrical wiring and internal cladding materials usually are not subjected to damaging water ingress.
The potential risks of water ingress with standard acrylic tray and wall showers is critical on its own but becomes even more important if you need to use a wet area shower.
Even small quantities of moisture damages some flooring products, particularly the particle board type, bringing about swelling, popped joints and nails/ screws and eventually the whole degradation from the material.
A water-resistant membrane is vital in wet areas both for floors and walls. Coverings including tiles or vinyl don't offer an adequate degree of protection independently.
Merely a recommended waterproof membrane can give you real reassurance.

POOLS & WATER TANKS
Waterproof membranes form an essential role in maintaining a great seal beneath and around regularly, water tanks, and sewerage treatment tanks.
Waterproof membranes here have to be able to withstand the big pressures associated with containing large volumes water.
WALL & Roof tiles
It may be particularly tough to ensure an efficient waterproof layer underneath tiles must be good adhesion is required for screed.
Effective waterproofing is important especially where tiles are utilized in wet areas because the gaps between tiles enables easy water ingress.
UV exposure can also be an issue and then for the need for a membrane that is certainly appropriate 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 right.
This is both for older style and more modern constructions. Whether you’re doing a new build or repairing a preexisting leak it’s crucial that you ensure that the waterproof membrane works and durable.
FORMWORK
Waterproof membranes play a huge role as both a barrier against water penetration as well as 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 in the concrete type need the careful putting on a highly effective waterproof membrane.
This applies to balconies, terraces, and planter boxes, all of which frequently cause water ingress problems.
BALCONIES & TERRACES
Waterproof membranes are necessary here too as with all 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 water-resistant membrane should cover not simply the bottom and also extend partway up adjoining walls in order to create a satisfactory barrier.
FLOORS
Water damage is probably the most typical and dear insurance jobs. Water leaks may damage floors over a long stretch of time 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, as well as in older buildings where adequate drainage may not have been designed or that are part of your website.
Burst water pipes can also do significant damage below ground if basement and foundation level structures are certainly not protected by a water-proof membrane.
In many cases these areas tend to be out of sight, from mind and water seepage can cause considerable damage before it’s noticed including slumping foundations, cracked and bowed walls, rotting timbers, as well as the growth of unhealthy levels of mould.
CONCRETE
Concrete buildings are surprisingly prone to water damage, especially modern flat roof designs where water can pool and accelerate the rate of structural decay within 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 permit water ingress even more in to the building envelope.
Such a damage can be extremely expensive for fix therefore, the installing of a reliable waterproof membrane is crucial.
WATERPROOFING MEMBRANE TYPES
Waterproof membranes come in a range of types suitable for different applications and types of conditions.
Membranes need to be flexible and capable to expand and contract when temperature changes make the building surface to advance.
Which meets your needs is determined by several factors. You may want to consider the following aspects:
UV exposure
Kind of substrate
Exposure to dirt & traffic
Sized area to be covered
Internal or external use
Storage of potable water
It’s important to select the right waterproof membrane material for the specific job and know how to put it to use.
Remember, the most important reasons behind waterproof membrane failures are poor or inadequate preparation and incorrect product choice.
