    Crawlspace Waterproofing in Front Royal, VA

    Our client was dealing with a recurrent issue that was causing significant distress. Every time it rained, their crawlspace would flood, and the water would overflow into their home. The client explained the distressing situation of having to resort to using a shop vacuum whenever the weather forecast hinted at rain. This was not just inconvenient but also became a source of constant worry for them.   To address this problem, we decided to install a comprehensive waterproofing system. Our solution was designed to not only tackle the current issue but also to prevent future occurrences, providing the client with peace of mind during rainy weather.   The installation process began with the placement of drainage matting. This matting serves a crucial role in channeling water out of the crawlspace, effectively preventing it from pooling and causing flooding. It provides an effective path for water to flow, directing it towards the drainage system instead of allowing it to seep into the floor.   Next, we installed CleanSpace, a high-quality crawl space vapor barrier that drastically reduces the humidity level in the crawl space. This helps to keep the space dry and significantly decreases the chance of mold growth, which is often a concern in damp environments.   To further enhance the protection against moisture, we encapsulated the crawlspace using SilverGlo insulation. This product has a radiant barrier on the exposed side that reflects heat back into the crawlspace, helping to maintain a comfortable temperature. It also acts as an additional barrier against moisture, ensuring the best vapor protection possible.   Understanding the client's frustration with the continuous use of a shop vacuum, we installed a TripleSafe sump pump system. This advanced system offers three levels of protection, ensuring that even in the case of a pump failure or power outage, the system will still operate efficiently. With this system in place, the client no longer has to worry about manually removing water from the crawlspace. ; We also installed discharge lines to effectively guide the water pumped out by the sump pump away from the property. This helps to prevent any water from pooling around the foundation and finding its way back into the crawlspace.   Finally, to ensure the durability of our solution, we attached an IceGuard system. This innovative component allows water to escape from the sump pump discharge line if it becomes frozen or blocked for any reason. This feature is particularly beneficial during the colder months when freezing is a common issue.   Through this comprehensive approach, we were able to provide a lasting solution to the client's problem, ensuring their crawlspace remains dry and safe from potential water damage, regardless of the weather conditions.   Get a FREE Quote!
