Waterproofing Coatings & Membranes

Fluid-applied or sheet membranes and elastomeric coatings that block water intrusion and protect embedded steel.

Waterproofing coatings and membrane systems include fluid-applied or sheet membranes and elastomeric coatings applied to decks, plazas, and below-grade concrete to block water intrusion and protect embedded steel from corrosion.

02

Costal Concrete installs these systems on high-rises, parking decks, balconies, and plazas for leaks, ponding, and planter waterproofing failure — aligned with ACI 515 and ASTM waterproofing standards.

03

Successful waterproofing starts with detailing: drains, transitions, penetrations, and flashings. We prepare the substrate, repair defects, and install systems suited to UV, traffic, and Florida weather.

04

A continuous waterproof barrier is one of the most effective ways to slow chloride-driven corrosion and extend the service life of coastal concrete structures.

01

Fluid-applied vs sheet membrane — which is better?

Both can perform well. Fluid-applied systems excel at complex geometry; sheet membranes offer consistent thickness. We recommend based on substrate and detailing.

02

Can waterproofing be installed over existing coatings?

Sometimes, if adhesion and compatibility are verified. Often failed systems must be removed to sound substrate for a durable bond.

03

How long do deck membranes last in Florida?

With proper maintenance and traffic coatings where required, quality systems commonly deliver many years of service in coastal climates.

04

Do you waterproof planters and plazas?

Yes. Planter and plaza waterproofing is a frequent failure point; we address drainage, root barriers, and membrane continuity at walls and drains.
