Considering the surface showed major signs of contamination and rebar was exposed and oxidized/rusted. It was best decided to abrasively blast the concrete in lieu of high pressure water so that the steel rebar could be descaled while blasting.
The incredible amount of concrete deterioration created the need to restore the concrete about 2 -3 inches (depending on different areas). For the resurfacing stage of the project, Miami-Dade crews selected an ultra-dense 10,000psi, quick curing mortar – Epoxytec MortarTec Silicate.
Lift station maintenance crews top coated the underlayment, consisting of Epoxytec Mortartec Silicate (rebuilding mortar) and Epoxytec CPP (epoxy liner) with a urethane-modified-epoxy (UME). Epoxytec Uroflex is a UME and proven with over 2,000,000 square feet coated at Miami-Dade Water & Sewer since 1989.
Note: During this project, Uroflex came in seafoam green (used here as the first coat), and in red (used as the second coat).
The total system applied:
