Protecting the homes and offices we build is a critical aspect of the construction phase and this protection comes in a variety of types. Perhaps the most crucial protections we can provide are the ones which inhibit the various elements that bear down on these buildings every day. Each of nature’s elements do specific damage, for example the sun can cause color fading and drying of certain sealants while the wind causes friction damage, excessive force trauma and in some cases, structural damage due to repetitive motion. However, the most destructive element in nature’s arsenal is H2O and the only way to protect our buildings from this problem is with exterior waterproofing systems.
Water creates it’s destruction in several ways and the damage from each of them is specific to the method. For example, frozen water expands as the ice crystals form causing the materials which the water soaked into to also expand during the freezing process. Certain man made materials like oriented strand board and medium density fiberboard can’t handle this type of stress. However, liquid water is actually worse because it creeps further into the contaminated area as long as the water supply is available. In other words, as long as the rain continues, the leak will continue and your building will keep soaking up the excess moisture. Contractors work to avoid moisture problems by applying various water barriers as part of the building’s exterior waterproofing. Most of these barriers are either polymer sheets or rubberized asphalt sheets designed to seal the various cracks which occur in any construction job.
Rubberized asphalt is not a new product, in fact it has been around for a few decades as a road surfacing material. It’s primary benefits in this aspect were smooth application, sealant properties and noise control. All of these benefits were considered useful in other applications so several smart engineers decided to adapt this material as a construction sealant. For the purpose of exterior waterproofing, rubberized asphalt is both the adhesive surface and the actual sealant, but it doesn’t work alone. The typical exterior waterproofing membrane is a thin but extremely durable sheet of polymer with an even coating of the rubberized asphalt which contacts the building’s sub-siding. This design allows for simple installation and the product is also easily sealed along the edges, plus repairs are usually simple if the membrane gets damaged during construction.
