Torch On VS Spray On Waterproofing

During these rainy days, it crucial to waterproof.Read on to find out more on how to go about picking your best option in the multiple available options.

During these rainy days, it crucial to waterproof. As simple as that might sound, technical terms like “torch-on”, “bitumen”, and “spray-on” can get us all confused, making us dread an essential part of household maintenance. So what do we go for when so many options are presented to us? Even though torch-on waterproofing solutions might have its benefits, spray-on has time and time again proved to be superior, in many respects.

1. What is the difference between torch-on and spray-on waterproofing?

Bitumen torch-on waterproofing is a blend of bitumen and polymers, which are applied to a polyester or fibre-glass reinforcement membrane. It is an exclusive and specific waterproofing solution that works especially well on flat concrete roofs, foundation and retaining walls, flashings, parapet walls, expansion joints, corrugated and IBR roof laps and roofing screws, as well as gutters, flower boxes and water retaining structures. Torch-on is known for being a stronger, sturdier membrane and is generated to keep surfaces safe from damp and water. As it is damp waterproofing action, it averts the danger of logging water through its water-resistant surface.

Spray-on waterproofing, on the other hand, is a procedure by which a liquid waterproofing agent is applied to a surface. As presented in the name, this method of waterproofing is sprayed on, usually by a knowledgeable and experienced expert, by using a spray gun. The waterproofing agent exists the gun and is applied as a liquid form, but dries into a pliable, blocked membrane that water just cannot enter through.

2. Why use Spray-On Solutions?

This waterproofing solution is not just economically friendly, and non-toxic, but it also can be applied to any surface and bond with it very well. This includes concrete, masonry, stone, fibre cement, fibreglass, steel, tiles, etc. What this “bondability” means is that the spray-on waterproofing won’t be coming off.

As spray-on is so easy to apply, it can be used to large spaces, without a hassle and in a brief period. This would mean that projects can be completed on time, without a lot of manpower. It also means that labour is cheaper and that clients have their homes and building waterproofed in no time. The best products to use for spray-on applications are Silicone, Polyureas and Polyurethanes and mixtures of these. Out of these options, Silicone usually tends to be the most cost-effective, but also the least durable. When choosing to use silicone, it would be best to use it in areas that don’t require a lot or any traffic. Otherwise, if a stronger blend is required, it is best to go for the more durable, and a bit more expensive, Polyurea and Polyurethane. It also entails all finer details to be adequately sealed. All that is needed is to spray the required area with the coating, and the spray-on applicator will ensure that no space goes unturned.

Spray-on waterproofing has many advantages, the most salient being that it is seamless. It has and requires no joints which means that there are less weak areas for water to enter. Moreover, when your roof is coated with a UV top coat, it will protect the membrane against the sun for many years.

Other, more traditional waterproofing methods, like torch-on, can still be beneficial, but spray on solutions have proven to be more effective – especially in the long run.

AMAZING JOB EXCELLENT TEAM

Great experience with Bitumproof Waterproofing. We had water damage in our basement from some foundation cracks and the company ran as a first class business all the way through. Jose came out to give us a quote that was easily scheduled and he gave a great explanation of what they would do. They have a discount so make sure to ask about that. We had a lot of different jobs going on at the same time and we ended up getting thinking they didn't take the discount off, but Jose called back immediately after we called the office to make sure everything was in good order, and turns out the mistake was on our end. Highly recommended.
