The Third High Reservoir is adjacent to Fort Reno Park in northwest Washington, D.C. Constructed in the mid-1950s, the reservoir is a sub-surface concrete structure measuring approximately 380 feet x 300 feet and 26 feet deep.
PENEPLUG, a rapid-setting, crystalline compound, was applied to stop all active leaks in the floor of the reservoir tank. SGS then routed out all leaking construction joints, visible cracks and leaks, and cut back any exposed rebar stubs and damaged concrete. PENECRETE MORTAR, a crystalline repair grout, was applied to the prepared areas. In addition, to protect the reinforced concrete structures from further water penetration due to the reservoir’s high hydrostatic pressure, PENETRON, a topical crystalline material, was applied as a slurry to permanently waterproof the concrete surfaces.
