Kiley Park - Tampa, FL

Challenge
Kiley Park in Tampa downtown, FL, follows a geometric layout of water, paths and lawns and was completed in 1988. Soon after, water began to leak into the underground parking garage below the park, which led the owners to drain fountains and plant grass in a large reflecting pool. Drainage was insufficient, causing the brackish water of the Hillsborough River to backflow into the gardens, killing the crape myrtles.

Solution
After clearing away the trees, the complete built-up had to be removed down to the concrete deck before installing the new waterproofing system over the cleaned and primed surface. The liquid-applied resin adheres to the substrate over the entire surface and forms a seamless membrane. Due to its fleece reinforcement, the membrane is capable to bridge cracks and to compensate for structural movements. The fact that the membrane is rot and root resistant and FLL tested made Kemper System the ideal choice for waterproofing the complete plaza and planters. On top of the waterproofing membrane, soil was replaced with a lighter hybrid of sand, rock and topsoil, lessening the weight load on the parking garage below. Many of Kiley’s original pavers were restored and reinstalled, as well as several water features to maintain Kiley’s original design.
