Whether hot or cold, fluid-applied waterproofing systems have the advantage of being monolithic and seamless compared to sheet membranes. Seams are generally where systems fail and being able to apply a membrane that is seamless eliminates these elements of potential failure. Fluid-applied materials also provide particular advantages in vertical applications, they are much easier to install than sheet membranes. By being a liquid that can fill naturally occurring imperfections in the substrate, fluid-applied membranes become part of the existing substrate. Whether the fluid-applied product application is spray or roller/brush, they are much less labor intensive compared to installing pre-formed sheet membranes and having to seal all the seams. This advantage can save up to 60% in labor costs. Along with the labor cost savings, the fact that many products like IWS’s Water Proof can be installed over “green” concrete, with these advantages, construction schedule timelines can be greatly reduced.
Fluid-applied waterproofing systems can be used in a variety of application scenarios, including roof decks, plaza decks, split slab applications, vertical foundation walls, tunnels, parking structures, balconies, terraces, fountains, planters, and industrial/commercial ponds and containment areas. In addition, IWS fluid-applied products can be used over a large variety of substrates including concrete, wood, foam, and over many existing thermoplastics and rubber roofing sheet membranes, making it in many cases the ideal solution for new construction waterproofing and waterproofing restoration projects.
Hot fluid-applied products require more material preparation time and are typically not as safe to use, but can be advantageous in certain climate conditions and with certain substrates as opposed to cold applied products. Cold applied materials offer the most convenience in preparation since the material do not need to heated and are safer to use. Also, cold-applied products come in dual-component formulations that allow a quick cure for high-build and thickness of the material in a one-pass application, as well as single component systems. IWS’s Water Block fluid-applied waterproofing product is very versatile, in that it can be applied with a hot or cold spray application process or with a brush or roller.
