Torch-on waterproofing, also known as torch-applied waterproofing, is a method of waterproofing flat roofs, decks, and other surfaces by heating and melting a waterproofing membrane, which is then applied to the surface with a torch.
Where it began
The history of torch-on waterproofing can be traced back to the early 20th century, when asphalt-based membranes were first used to waterproof flat roofs. As the use of flat roofs in construction increased in the 1920s and 1930s, so did the need for a reliable and durable waterproofing solution. Asphalt-based membranes were initially used as a waterproofing layer, but they were not completely waterproof and required frequent maintenance. In the 1940s and 1950s, new waterproofing technologies were developed, including modified bitumen and PVC membranes. These membranes were more durable and waterproof than the traditional asphalt-based membranes and were applied using a torch.
The Evolution
Torch-on waterproofing became increasingly popular in the 1960s and 1970s, as it was a faster and more efficient method of applying waterproofing membranes compared to other methods, such as cold application or hot mopping. The use of modified bitumen and PVC membranes also made torch-on waterproofing more durable and long-lasting.
In recent years, new technologies have been developed, including self-adhesive membranes and liquid-applied membranes, which can be applied without the use of a torch. However, torch-on waterproofing remains a popular and widely used method of waterproofing flat roofs, decks, and other surfaces due to its durability and long-lasting performance.
In conclusion, Torch-on waterproofing is a method of waterproofing flat roofs, decks, and other surfaces by heating and melting a waterproofing membrane, which is then applied to the surface with a torch, the history of torch-on waterproofing can be traced back to the early 20th century. It has evolved over time with new technologies and is still widely used in the present day for its durability and long-lasting performance.
FAQ's
Waterproofing is an essential component of building construction that helps protect structures from water damage. Torch on waterproofing is a popular method used by many contractors in Sydney for its durability and versatility. In this article, we will discuss torch on waterproofing in more detail, including its advantages, potential drawbacks, and lifespan.
What is Torch on Waterproofing?
Torch on waterproofing is a method of waterproofing that involves the use of modified bitumen and a reinforcement mat. The modified bitumen is heated with a torch, allowing it to melt and adhere to the surface being waterproofed. The reinforcement mat is then embedded in the melted bitumen to provide additional strength and durability. Torch on waterproofing is commonly used for flat roofs, decks, and balconies.
Advantages of Torch on Waterproofing
Torch on waterproofing has several advantages over other waterproofing methods. It is a durable and long-lasting solution that can last up to 20 years or more with proper installation and maintenance. It is also versatile and can be used on a variety of surfaces, including concrete, metal, and wood. Torch on waterproofing is also resistant to UV rays and can withstand harsh weather conditions.
Can You Waterproof Over Torch On?
It is possible to waterproof over an existing torch on membrane, but it requires proper surface preparation and the use of compatible materials. The existing membrane must be in good condition, and any damage or deterioration must be repaired before applying a new layer of waterproofing.
Torch on Membrane Detailing
Proper detailing is essential for a torch on waterproofing system to function correctly. Detailing refers to the process of sealing areas of the membrane that require additional protection, such as seams, edges, and penetrations. The detailing process must be done correctly to prevent water from penetrating the membrane.
Lifespan of Torch on Waterproofing
The typical lifespan of a torch on waterproofing system is 20-30 years with proper installation and maintenance. Regular inspection and maintenance can help identify and address any issues before they become significant problems.
Disadvantages of Torch on Waterproofing
While torch on waterproofing has several advantages, there are potential drawbacks to consider. Torch on waterproofing requires proper training and safety precautions, as the use of a torch can be hazardous. Additionally, the installation process can be time-consuming and expensive compared to other waterproofing methods.
Can You Coat a Torch Down Roof?
It is possible to coat a torch down roof with a compatible coating material. A coating can help extend the lifespan of the membrane and provide additional protection against UV rays and weathering.
Is Torch on Roofing Good?
Torch on waterproofing is a popular and effective method for waterproofing flat roofs, decks, and balconies. Its durability, versatility, and resistance to harsh weather conditions make it an attractive option for many contractors in Sydney.
How to Apply Waterproof Membrane
The process of applying a torch on waterproofing membrane involves several steps, including surface preparation, membrane installation, and detailing. The membrane is heated with a torch and applied in layers to ensure a watertight seal.
What is Torch on Roofing Called?
Torch on roofing is also known as "torch down" roofing, due to the process of melting the modified bitumen with a torch.
Torch on waterproofing is an effective and durable solution for waterproofing buildings and structures in Sydney. Its versatility, resistance to harsh weather conditions, and long lifespan make it an attractive option for many contractors. However, it is essential to follow proper installation and maintenance procedures
