The material is recyclable and flexible. On top of that, it is efficient. On the low end, you’re going to end up paying $3.25 per square meter. At the maximum, you’ll pay nearly $15 per square meter. Remember that it is available in two thicknesses, 45 and 60 mils. The thickness you choose will ultimately alter the price.


Rubberized Asphalt

Another waterproofing material is rubberized asphalt. This material works great for keeping your home protected from the elements. However, it is primarily found on roofs for commercial businesses. 790-11 hot rubberized asphalt is best for two specific applications. If you’re dealing with extensive vegetative assemblies or intensive roofing assemblies, you’ll want to go with this material. It will prevent problems and provide you with the best results. This material is sometimes utilized to provide a waterproofing cover to RVs and campers. There’s a lot to like about rubberized asphalt. For instance, it is very tough.

It can withstand everything Mother Nature throws its way. Simultaneously, it is very flexible and the moisture vapor permeance is very low. This ensures that you’re going to get good results. The material is commonly used to waterproof bridges, plazas, parking spaces, and commercial roofs. When used on concrete, the material can help cut down on cracking, noise, and hydroplaning. It will also enhance the durability of the underlying material.

The cost of this material will depend on how big the treatment area is. However, you can buy a 4.75-gallon bucket for roughly $50. The material usually dries within 3-4 hours after being applied.




Another very popular waterproofing material is thermoplastic. This material might not be the cheapest out there, but it offers a wealth of benefits. For instance, it is one of the strongest waterproofing materials on the market. On average, it can provide you with 50 years or more of waterproofing durability. This makes it longer lasting than many of the alternatives. When heated correctly, the material will transform from solid to semi-solid. This allows a professional to seal the sheets or panels together. In return, this makes thermoplastic waterproofing more effective for the intended purpose. The material also features elastomers.
