If we had to ask you the different types of waterproofing systems, how many could you possibly name, 5,10,20

Well, don’t worry because, in this blog, we will only be mentioning a few specific systems but primarily focus on one.

Three different types of waterproofing systems.

When it comes to the waterproofing of your property or specific areas, there are just some waterproofing systems that work far better than others. That is why we wanted to mention these systems and in future blogs, we will discuss the differences in the techniques and the advantages to each technique.

Acrylic Waterproofing Systems: 
The acrylic waterproofing system consists of a copolymer emulsion in paint form and a reinforced fiber membrane. The membrane is manually inserted between multiple layers of acrylic waterproofing coats. (In English: You use a special waterproofing paint to coat a specialized waterproofing membrane)

Self-Adhesive Membrane Method: ( Otherwise known as Uni-flash ) Is a self-adhesive polymer modified bitumen, secured with a Neoprene primer, and reinforced to an adhesive fabric, should it need to be painted over if required. This very effective system is normally used as a counter flashing and or where gas heat is not recommended.   (In English: one side of the membrane has a sticky section that can be applied to surfaces.)

Torch-On Membrane System: is a waterproofing system that uses an LPG (Low-Pressure Gas) torch to heat fuse a polymer-modified bitumen membrane to a primed surface area. (In English: You use a flame torch to heat-fuse the special membrane to the surface that you want to be waterproofed)

Now that you know the three most popular methods it’s time to get down the real meat of this article, which is going into more detail about Torch-On Waterproofing Systems. Why did we mention Acrylic and Self-Adhesive , because even if our preferred method is and will always be Torch-On, we do use other methods for systems that Torch-on is not an applicable method?

Even though we did explain it briefly, we felt that we needed to take this opportunity to explain it fully and in much more detail so that those that are interested can fully understand what it is when we say that we offer Torch-On Waterproofing.

THE WHAT & HOW OF TORCH-WATERPROOFING SYSTEMS

It’s no secret that Torch-On Waterproofing is one of the most common names in the waterproofing industry, we have often encountered many of our clients who have asked us if we will be using the torch-on method before we even go through the options.

However, a lot of people don’t necessarily understand what it is or exactly how to apply it. But hopefully, after this blog, you will be one of those who aren’t like those from the previous sentence. You will understand all the most essential parts of Torch-On Waterproofing.

THE WHAT OF TORCH-WATERPROOFING SYSTEMS

Torch-On Waterproofing is a polymer bitumen waterproof membrane. This system is applied with LPG (low-pressure gas) Torch. The membrane is heat-fused onto a surface that has had a priming application applied to it.

This membrane consists of a mixture of penetration bitumen, modified with Atactic Polypropylene (APP), and reinforced with a layer of non-woven polyester, This membrane is flexible and resistant to tears and general foot traffic.

The Reason for Liquid Surface Primer is to act as a bonding agent for the Torch-On Membrane and to reduce air entrapment, act as a seal for any cracks or crevices, reduce porosity, dust or high residual moisture which will cause blistering of the membrane.

In some instances, a Specialised silver paint is then applied to the newly fused membrane as a U.V Protector from the sun, due to the fact that Torch-On membrane can succumb to damage and lose durability, due to constant contact with direct sunlight. Whereas the Silver acts as a reflector for that direct light (But this is generally if your waterproofed area is in direct contact with the sun)

HOW TO APPLY IT

Please be aware that although we wanted to share the application process. We highly recommend that you contact a professional waterproofing company like All Roof Waterproofing to do the actual waterproofing application, due to the fact that this process is very complex and it should only be handled by a trained professional.

When it comes to the application of the Torch-On waterproofing, there isn’t a one size fits all, kind of process. Each surface area that needs to be waterproofed may require a specific way of applying the Torch-On. That is another reason why we recommend that you call us.

  • Starts by the cleaning and preparing of the surface that needs to be waterproofed. If your valley cutters are being waterproofed, then the tiles will need to be opened and placed in a reachable distance to be replaced. insert when completed. If it is a fish pond or water-logged area. The water will have to be drained. And lastly, if it is at the base of your building, a trench of about 1.5 meters deep and 1 meter wide will have to be dug
  • Depending on the surface, we can either apply a plain torch on a system (silver coat required) or mineral surface T-O membrane (no silver aluminum paint or maintenance required)  that the waterproofing will be applied to, you will add a coat or two of primer to the surface.
  • The Torch-on Waterproofing Membrane will then be fitted and cut in order to cover the area and to create ways for the water to flow without getting under the sheet.
  • An Experienced and Professional Waterproofing Torcher will then use the Flame torch to fuse the Membrane onto the surface with normally overlaps of 100 mm, side laps of 75 mm, and  100 mm upturns. Waterproofing generally needs to be counter flashed with a three-layer Bituminous waterproofing system.
  • Lastly, the Torch-On is then coated with Silver Aluminium paint in order to protect against sun rays (only if exposed to the sun on a regular basis). With regards to the waterproofing of the base of your building. You need to make sure that you have a durable object covering that torch-on to avoid any punctures coming from roots, or stones that may be in the soil when you put back the soil.
