Background

The Norris Center Olympic-size pool, with high dive towers on one end of the pool, consists of cast-in-place concrete foundations and walls and an at-ground level, cast-in-place concrete pool deck slab. The pool deck concrete is finished with ceramic tiles placed in mortar bedding over the waterproofing membrane; pool concrete walls and slabs are also finished with ceramic tiles set in mortar bed. Linear floor drains are set in the perimeter of the pool deck. Three underwater window openings are located in the pool walls. The structure's walls consist of steel columns covered with precast concrete panels and insulated precast wall panels on the exterior along the west, north and east elevations.

Solution

The tiles, mortar setting bed, and waterproofing membrane were removed to expose the structural deck slab. Repairs were made to delaminated areas found on its top and underside. A new waterproofing membrane, grounding, linear floor drains, and concrete topping were then installed to provide the slope for the finished floor. Delaminated tiled areas on the pool's bottom and walls were repaired with new tiles set in mortar bedding. The three underwater windows, existing lights, and speakers were removed. Their cavities were then enclosed with cast-in-place concrete and tiled.

Additional improvements to the pool space included replacing the existing steel doors and door frames with stainless steel and installing new aluminum doors. WJE also replaced the sealant on the exterior walls, restored the bleachers, and installed additional pool ladders and an ADA lift.
