Terraces are highly susceptible parts of any building as they are subject to direct sunlight, rainfall and other forms of weather exposure. Therefore, proper Terrace Waterproofing coating should be utilized for maximum protection.
Terrace waterproofing will protect against climate damage and help your terrace withstand extreme environmental conditions. Chemical treatment processes exist for waterproofing terraces.
Bituminous Membrane
Bituminous membrane waterproofing is an effective and long-term way of protecting terraces against water damage. The material can withstand high temperatures while still offering UV ray protection, being nonflammable and without toxins that harm the environment. In general, bituminous membranes are composed of polymer-modified bitumen mixed with inert materials like sands and slate extracts to stabilize its mechanical properties and ensure longevity of service.
Modified bitumen membranes are produced using a high-tech calendaring process and saturated and coated with SBS elastomeric modifiers to enhance thermal, chemical and aging properties before being reinforced with fiberglass or non-woven polyester yarn to further increase their strength and durability for resistance against ponding water and fatigue.
Green concrete-grade membranes can be applied on various substrates, but for best results it is crucial that you use an effective application method; failure can impact its durability negatively and ensure proper sealing at joints, penetrations and changes in plane.
This waterproofing material can be applied either by torch or hot mixture and should be used under dry conditions, after priming with bitumen primer and heating it until its underside film melts completely before sticking it down starting at its lowest points.
Polyurethane Liquid Membrane
PU liquid waterproofing coating is ideal for structures and substrates exposed to weathering. Due to its excellent durability and UV resistance, this type of liquid waterproofing can withstand harsh outdoor environments with ease.
PU liquid waterproofing can be easily applied quickly, making it an excellent solution for projects with limited working hours. This feature makes PU waterproofing especially valuable in protecting roof areas quickly, such as those needing protection quickly for stormy conditions or flat roofs which have proven more difficult to waterproof with other methods such as sheet membranes or spray application.
To apply a polyurethane liquid membrane, a primer coat must be first applied as an adhesion coat, followed by three finishing coats brush-applied using two component polyurethane mixed as per design ratio and allowed to dry for eight hours before moving on with subsequent layers.
Once applied, ISOFLEX-PU 500’s aliphatic water-based polyurethane membrane forms an elastic continuous membrane without joints or seams that is highly resistant to standing water, making it suitable for universal waterproofing as well as local waterproofing in specific areas. Furthermore, polyester fabric reinforcement may help prevent the formation of ice dams at edges of flat roofs as well as on vertical elements such as parapets and stairwells; additionally it protects metal elements against corrosion.
Epoxy
Epoxy is an extremely strong and resilient material commonly used for laminating coatings, concrete repair and floor covering applications. It’s particularly popular as an option for flooring systems due to its resistance against heavy foot traffic, impacts, abrasion and water. Epoxy comes in various colors and finishes that can be poured or applied with an applicator; additional pigments can also be mixed into it for different hues. Ideally it should be designed specifically for outdoor use in order to withstand UV light exposure.
Waterproof coatings provide an effective means of waterproofing terrace surfaces and can be easily applied over other coatings. Their variety of colors and finishes allows it to match any surface easily; suitable for concrete, masonry and metal and highly durable.
This type of epoxy is highly resistant to abrasion and corrosion, and can withstand extreme temperatures. This makes it the ideal choice for areas exposed to chemicals, oils or liquids; in addition it’s great for fixing leaks or cracks.
Epoxy waterproofing products have proven themselves as reliable options that can last up to 30 years in residential settings, yet remain extremely cost-effective and provide an alternative to membrane systems. Before selecting one, however, it’s essential to research different types and prices as well as hiring a reputable contractor in order to ensure a professional job.
Fiber Net
If you are searching for an effective product to protect and strengthen your terrace from leakage of water, fibre net is an easy and affordable solution. Available from companies like Pidilite and Mr Fix It, this product features crack bridging fibres to ensure no water seeps into walls or structures of houses and ensure safe walking on terraces.
Waterproofing systems made from special binder cements containing high performance additives and acrylic polymer emulsion are used to protect concrete structures from moisture intrusion, using crack bridging capacities up to 2mm. Applications include waterproofing basement retaining walls, roof slabs, balcony floor slabs, sumps, swimming pools, water tanks, sewage treatment plants and other extreme service class structures.
Before applying waterproof coating, it is critical that the surface be properly prepared. Concrete must be cleaned extensively before being left to dry for 24 hours before the first layer of waterproofing coating is applied on top. In order to provide extra strength and reinforcement for large terrace structures, fibre net is often added between these layers for additional strength and reinforcement.
