Project: Davenport City Hall
Location: Davenport, IA
Date: January 2012
Help the City of Davenport regain useable storage space, exercise room, break room, and City employee work space. The north side of the City Hall building suffered from unfortunate non-stop slow and steady groundwater seepage that would increase exponentially when any size of precipitation became present. The groundwater was not only a nuisance for the General Contractor that was performing work on the building but also for the city employees that used and occupied the different areas of the basement.
A Waterguard XL water control system, a Triple-Safe sump system, and a Brightwall wall panel system were specified and installed to discontinue the further infiltration of the groundwater seepage into the structure’s basement. A 170ft trench was created in a very thick, hard, wire reinforced concrete floor (with continuous water infiltration) to allow for the installation of 170ft of Waterguard XL. The Waterguard XL drained into a Triple-Safe sump system with two Zoeller M98 ½ H.P. pumps and an existing sump pit with a high power Zoeller pump. 1ft tall Brightwall panels were installed to cover the weep holes being drilled in the wall above floor level.
Prior to installation a large amount of plastic was installed by the installation crew to create an envelope and isolate the areas of repair from those not in need of repair. A large air scrubber was also provided by Werner Restoration to help create a safe dust free environment for the installers and City employees. The two-man installation crew completed the entire job in 4 days time.
