Coastal Waterproofing

Comprehensive Protection for Florida’s Coastal Buildings

Living and building near the coast brings constant exposure to moisture, wind-driven rain, salt spray, and rising water levels. Over time, these forces wear down even the most well-constructed buildings. At EIRS, our Coastal Waterproofing service is designed specifically for high-risk properties along Florida’s coastline — offering targeted, building-wide solutions that stop water intrusion before it becomes structural damage.

What Is Coastal Waterproofing?

Coastal Waterproofing is a layered system of sealing and protecting your building envelope — including the roof, walls, foundation, walkways, and balcony structures — against water infiltration, salt corrosion, and long-term decay. Our approach blends industry-best materials with construction techniques that address known coastal vulnerabilities, particularly for condominiums and mid-rise buildings near the water.

What’s Included

Exterior Wall & Façade Sealing

Application of high-performance coatings and elastomeric membranes to protect concrete, stucco, and masonry surfaces from moisture and UV damage.

Drainage & Slope Correction

Improper slope leads to water pooling and eventual structural damage. We assess and correct drainage issues to ensure water flows away from the structure and off the deck.

Foundation Protection

Sealing of below-grade walls, slab edges, and exposed foundations using commercial-grade membranes and joint sealants.

Flood Panel & Barrier Integration

Option to integrate FEMA-rated flood protection systems, including aluminum flood panels from Hydra Flood Pro.

Roof Membrane Systems

Long-lasting PVC and TPO membranes that tie into wall flashing systems to prevent edge water intrusion.

Joint & Expansion Sealants

Replacement or installation of high-movement sealants around windows, doors, handrails, and vertical seams.

Why It Matters

  • Water intrusion is the #1 threat to structural longevity in coastal buildings.
  • Salt and humidity corrode rebar and steel faster than inland environments.
  • Insurance carriers are demanding stronger waterproofing and inspection documentation.
  • New Florida condo safety laws require proactive maintenance for aging structures.

Building Envelope Evaluations

Before we recommend any waterproofing solution, we evaluate the condition of the building’s full envelope — including walls, balconies, windows, and roofing transitions. Our assessments help identify water intrusion risks, sealant failures, or areas of exposure that often go unnoticed until they become costly.

How We Work

Our team performs a full site assessment and visual inspection, including aerial drone footage if needed. We then develop a custom waterproofing plan tailored to your structure’s condition, elevation, materials, and maintenance history.

You receive:

  • A comprehensive scope of work
  • Recommended materials and methods
  • Optional integration of flood panels and coatings
  • A clear roadmap for execution
