Waterproof Concrete

The Miami-Dade County South District Wastewater Treatment Plant is undergoing a two-phase construction using crystalline chemical waterproofing. Phase 1 includes 52,000 sq. ft. of surface area treated with a two-coat system, and phase 2 uses the crystalline technology, in admixture form.

In crystalline PRAHs, the reactive chemicals use water to migrate into and travel down the capillaries of the concrete. The process initiates a chemical reaction involving the crystalline chemicals, moisture, and the by-products of cement hydration, which forms a new non-soluble crystalline structure. This integral structure fills the capillary tracts and renders the concrete waterproof.

Cracks in basement slabs produced significant leaks, leading to several inches of standing water in some areas.

Where possible, crews repaired cracks in slab joints with a waterproofing repair mortar.

Where necessary, crews installed new reinforcement and placed new slabs of concrete with integral waterproofing admixture.

After repairs, basements are substantially dry.
