Description
The Galloway Detention Basin retention tank, a below-grade concrete tank structure, holds stormwater runoff to reduce peak flow volumes in the downstream system until it can be forwarded to the West Plains wastewater treatment plant for processing. The dam consists of an earthen embankment and cast-in-place concrete principle and auxiliary spillways. Both were constructed by John Adams Construction, the project’s general contractor.
Products Used
Once added to the concrete mix by Stewart Morrison, the ready-mix concrete supplier, the active ingredients in PENETRON ADMIX SB generated a non-soluble crystalline formation throughout the pores and capillary tracts of the treated concrete. These crystals permanently self-heal and seal micro-cracks, pores, and capillaries against the penetration of water or liquids from any direction. The concrete is now impermeable.
