Mersco Miami specializes in waterproofing systems, concrete repair, and building envelope protection that shields South Florida properties from the moisture, heat, and salt air that accelerate structural deterioration across Miami-Dade and Broward County.
Building Protection
Mersco Miami builds its service model around building envelope protection. Every repair, coating, and sealant we apply is chosen for its ability to stop moisture, resist South Florida's environmental conditions, and extend the life of the structure underneath. We are not just patching surfaces, we are protecting assets.
From waterproof membranes on rooftop decks to elastomeric coatings on exterior walls to expansion joint sealants at every vulnerable seam, our work defends the building from the outside in.
Protection Services
Every service we offer is oriented around one goal: keeping moisture out of the building envelope and structural concrete in service longer.
Concrete repair and structural restoration using moisture resistant repair mortars and anti corrosion coatings that stop rebar deterioration from continuing after repair.

Talk to Our TeamWhy Owners Trust Mersco Miami
Every dollar spent on proper waterproofing and concrete protection in Miami saves several dollars in structural repair cost down the road.
We trace water infiltration to its source before proposing repairs. Fixing the symptom without fixing the entry point wastes money.
Not all membranes perform equally in South Florida conditions. We match the system to the exposure, the substrate, and the building type.
Joints are where buildings breathe and where water enters when seals fail. We take joint replacement seriously as a waterproofing function, not just cosmetic maintenance.
UV exposure, ponding water, thermal cycling, and wind driven rain all test coatings differently in Miami. Our product selections account for all of it.
We flag developing conditions we observe during a project, giving owners the option to address minor issues before they become expensive failures.
Miami averages over 60 inches of rain per year. Combined with salt air, intense UV, and high humidity, the building envelope is under constant attack. Water finds every crack, every failed joint, every unprotected concrete edge.
Mersco Miami seals buildings against that environment. Our waterproofing and concrete repair work is selected and applied to stop moisture from reaching the structural concrete underneath.
