Waterproofing & Vapor Barriers

Seamless Protection From Liquid Intrusion and Moisture Vapor Drive
Moisture intrusion can cause significant damage to coatings, substrates, adhesives, and structural elements—especially in environments that require sanitation, chemical resistance, or long-term performance. At Peckham Coatings, we install waterproofing and vapor barrier systems that stop water and moisture vapor at the source, before it can compromise your facility.
Whether you’re protecting a below-grade space, a slab-on-grade installation, or an overhead surface exposed to water, our systems are engineered for durability, adhesion, and long-term reliability.
Why Waterproofing and Vapor Control Matter
Uncontrolled water and vapor can lead to:
  • Coating delamination or blistering
  • Mold and mildew growth
  • Failed adhesives under flooring or wall finishes
  • Structural damage to concrete and masonry
  • Reduced insulation and envelope performance
Our seamless systems create a physical barrier to block liquid water and/or water vapor transmission, ensuring your finishes last and your building stays protected.

System Features & Options
  • Liquid-applied waterproofing membranes
  • Below-grade and horizontal slab vapor barriers
  • Systems compatible with adhesives, floor coatings, and tile installations
  • Fast-curing, walk-on ready formulations available
  • Integrates with trenching, wall transitions, and joint sealants
  • Fiber-reinforced and chemical-resistant options available
  • VOC-compliant and compliant with ASTM E96 and other standards
We select and install the right system based on slab condition, substrate porosity, moisture test results, and finished surface requirements.

Recommended For
  • Underlayment for Moisture-Sensitive Flooring (VCT, Sheet Vinyl, Carpet, Hardwood)
  • Food & Beverage Production Areas
  • Pharmaceutical and Lab Environments
  • Locker Rooms, Restrooms & Washdown Zones
  • Cold Storage & Refrigerated Spaces
  • Below-Grade Basements or Containment Areas
  • Any slab with elevated RH, MVER, or known moisture intrusion

You Can Expect
Our team evaluates every moisture challenge on-site and delivers a solution that meets both functional needs and long-term performance goals.
  • On-site slab evaluation and moisture/vapor testing
  • Detailed system recommendation based on your flooring or wall finishes
  • Professional, clean installation by trained crews
  • Seamless integration with coating systems or adhesive-based finishes
  • Reliable, documented results backed by industry-standard testing​
Start With a Strong Foundation
If you’re building or renovating over concrete, don't let unseen moisture undermine your investment. Our waterproofing and vapor barrier systems offer a dependable first line of defense—keeping your coatings, adhesives, and surfaces protected for years to come.
