Waterproofing is a technique for preventing water from entering a structure. Water proofing allows the building to breathe by screening excess holes, gaps, and leakages. There are several types of waterproofing materials. Here are a few common ones. Listed below are some benefits of each type. If you’re thinking about waterproofing your home or building, be sure to read this article. It will help you decide which method is right for your home.
Building waterproofing
Waterproofing concrete structures is an important aspect of the construction process. Although concrete is a cost-effective building material, its permeability to water and chemicals makes it vulnerable to deterioration. Ingress of water also introduces harmful chemicals that may react with the concrete and reinforce steel. Water can also evaporate from concrete, causing stains or patches on the surface. Building waterproofing membranes are necessary for preventing these issues. They can be applied to the entire building, including balconies and roofs.
Without waterproofing, cracks can develop in plaster, concrete, reinforced steel, and paint. Waterproofing extends the lifespan of these materials and reduces the need for building maintenance. It also helps preserve the aesthetic look of the building. Building waterproofing costs between 0.5 to 2 percent of the cost of the entire construction process. It will also reduce the amount of energy and drinking water required to maintain the structure. It will also reduce energy and water usage, and can help make the building more environmentally friendly.
Bituminous membranes
The method used to install a bituminous membrane is critical to its performance. The method used and the quality of workmanship will determine whether the membrane will be effective or not. The following guidelines should be followed for a successful bituminous membrane installation:
The best time for installing bituminous membranes is during the winter season. The membranes are made from bitumen, a hot melted liquid that can be applied to a roof, podium deck, or basement. Unlike traditional waterproofing materials, these membranes do not require a torch and are most effective on concrete flat roofs and gutters. Basements and retaining walls are also commonly protected with bitumen membranes.
Polyurethane liquid membranes
The application of polyurethane liquid membranes for water proofs is an effective way of preventing moisture intrusion in buildings. Once primed and dry, they can be applied at the specified coverage rate and dry film thickness. In addition, they must be cleaned and dust-free before application. Usually, it takes one litre per 4m2 of surface area. Suitable surfaces for the application of liquid membranes are bitumen, timber and roof areas. Moreover, it must be used where evapouration of entrapped moisture from the substrate is necessary.
The properties of waterproof membranes need to be able to withstand the elements. They should also be able to resist heavy wind, rainwater, and even daily use. The abrasion resistance of a membrane should be examined by workers, as rough objects can rip it and cause leaks. The chemical stability of the membrane is also important, as its inertness can cause it to break down.
Elastomeric wall coatings
Elastomeric wall coatings are a durable type of protective paint that adheres to almost any surface. This type of coating resists cracking and doesn’t require multiple coats, and it’s eco-friendly. It also provides years of water proofing protection, sealing hairline cracks and bridging shrinkage cracks while maintaining a smooth, attractive finish. Here’s a guide to using elastomeric wall coatings.
Elastomeric wall coatings are often used in exterior concrete/masonry walls, and they’re often the preferred choice for these applications. However, elastomeric wall coatings are notoriously difficult to apply correctly, and some types of elastomeric wall coatings should be avoided altogether. This article will cover the best practices for applying an elastomeric wall coating, including tips to prevent mistakes that could cause costly problems.
Hot-applied bitumen systems
Compared to pre-formed sheet membranes, Hot-applied bitumen systems for waterproofing require less preparation time. But a bitumen membrane must be prepared properly before installation. Bitumens that are modified with SBS polymer require special equipment to be heated to the appropriate temperature. This equipment is known as bitumen melters. They feature double-jacketed jackets and use hot oil or air to mix and apply the bitumen. An agitator must be running to ensure the material is heated evenly and at the correct temperature.
A hot-applied bitumen system is also commonly known as a roll roof. The base felt is pulled through large tanks of bitumen mixtures. The base layer is saturated with the tar-like bitumen mixture, which creates a waterproof membrane. The material is also breathable and highly resistant to rain and other forms of moisture. Hot-applied bitumen systems are best for waterproofing above ground and below-ground structures, but cold-applied liquid is often more convenient for a busy schedule.
Rycon
The commercial grade elastomeric roll-on waterproofing system known as Rycon is a versatile, high-performance waterproofing solution. This single-component, flexible coating forms an excellent water-blocking barrier on vertical structures, including walls and ceilings. Due to its 600% elongation, Rycon is capable of bridging hairline cracks and providing an airtight water-proof seal. Rycon can be applied to both interior and exterior surfaces and is an excellent installation surface for GFC Systems.
Wellshire counterclaims, but admits that the claims against RyCon are factually thin reed. Wellshire does not allege that it entered into an exclusive dealership agreement with RyCon, and characterizes the agreement as an “implied-in-fact” or “oral” contract. To establish that Wellshire benefited from exclusive rights to RyCon’s products, it must identify all documents that document its business relationship with RyCon.
