Located in Utah this project involved waterproofing a building where the foundation formed the exterior perimeter of a tunnel system that provided air return to a number of HVAC systems throughout the building. These tunnels were originally formed by casting a concrete trough; the perimeter being the building foundation with the floor and interior wall being separate components. The exterior perimeter foundation wall was waterproofed only on the inside by application of a tar-like coating. The finished foundational tunnels were approximately 2 feet tall and 3 feet wide and extended up to 175 feet. Water intrusions were present in several areas with standing water present. The contract involved cleaning, waterproofing and protecting the tunnel components from further water intrusion and water damage.
To start the actual repair process, steps were first taken to clean loose debris and then a cryogenic blasting was used to remove the previous bituminous coating and rust on the existing metal ceiling deck.
Once all non-concrete surfaces were treated, the concrete walls and floors were waterproofed with Penetron via spray application and all penetrations and non-moving joints packed with Penecrete Mortar.
This project proved a particular challenge because of the confined spaces, pumping distances and limited access. Not withstanding all of this, the tunnels are now waterproof. said Loran Hubbard of Lindhart Technical Services We were able to complete the project at a nice profit significantly under the next highest bidder. We applaud your fine product.
