DryZone, LLC Case Studies: Hall House- Governor's Mansion Guest House

Tuesday, June 28th, 2016 by Jessica Cregan


In 1790, the Governor’s Mansion Guest House, also known as Hall House, was built in the capital of Delaware. Now, in 2016, the basement of the historical house is having issues with water. Previously, DryZone worked on multiple historical projects regarding waterproofing such as Johnson Victrola Museum and Zwaanendael Museum. As well as another government contracted job, such as Assawoman Canal Bridge. As a well-known trusted vendor in Delaware, DryZone was contacted to come out to the Hall House and inspect the property, which is where we found water leaking through the walls of the basement. This was a challenge that DryZone was ready to solve. 



DryZone specializes in many products but the specific ones we used for this project were TrenchDrain, TripleSafe Sump Pump, and IceGuard System. When deciding on which drainage system to use, DryZone chose TrenchDrain for the basement. In order to keep the authenticity of the home, TrenchDrain was the right product to use because it sits at the same level of the basement floor, which was requested by those tasked with preserving the historical property. Next, The TipleSafe Sump Pump was installed to control the flow of water in the basement and to keep the area dry all the time. Lastly, the IceGuard System was installed. This product has many benefits, such as allowing water to escape from a sump pump discharge line if the pipe freezes or becomes blocked for any reason. Even if the pipe is buried under snow or an animal makes a nest, the water can escape, which allows the sump pump to keep the basement dry all the time.  All three products were installed to control the flow of water in the basement of the Hall House.  

We were able to meet the water challenge at the Hall House with our trusted waterproofing services and products. DryZone is happy to contract historical properties such as the Hall House and save the integrity of the historical mansion in Dover, Delaware.
