Protect Your Investment Below the Surface
A pool vapor barrier helps control moisture migration, protects concrete and surrounding structures, and improves the long-term performance of your pool—indoors or out. When installing a pool, the focus is often on finishes like tile or lighting—but what’s beneath the surface matters just as much.
Why Install a Vapor Barrier Around a Pool?
Whether it’s an indoor pool or an outdoor inground pool, moisture control is critical. Vapor barriers:
-
Prevent moisture seepage into concrete and surrounding soil
-
Reduce humidity that leads to mold, mildew, and structural damage
-
Help meet code requirements in commercial settings
-
Extend the life of insulation, drywall, and structural materials
-
Minimize costly repairs related to water damage
What to Look for in a Quality Pool Vapor Barrier
-
Low permeability (≤ 0.1 perms) to block water vapor migration
-
Puncture resistance to withstand concrete pours or backfilling
-
Reinforced construction for added durability and tear resistance
-
UV resistance for outdoor use during extended construction timelines
-
Fire retardance for indoor or public facility compliance
-
Flexible installation to adapt to curved or custom layouts
Vapor Barriers for Indoor Pool Installations
Indoor pools create high-humidity environments that can compromise framing, drywall, and insulation. A vapor barrier under the slab and behind wall finishes adds a crucial layer of protection.
Recommended Products:
-
Pro Crawl Anti-Mold Vapor Barrier with MPT™
An excellent choice for under-slab or behind-the-wall protection, this vapor barrier is engineered with Mold Prevention Technology for humid environments. -
Dura Skrim® 10 Mil Fire Retardant Reinforced Plastic Sheeting
This option combines strength and fire retardance, making it ideal for meeting indoor safety codes in commercial or residential pools.
Vapor Barriers for Outdoor Inground Pool Installations
Outdoor pool foundations are exposed to groundwater, rain runoff, and changing soil conditions. Installing a durable under-slab vapor barrier helps maintain pool integrity and protects from below-grade moisture intrusion.
Recommended Products:
-
Dura-Skrim® 20 Mil Reinforced Plastic Sheeting
A heavy-duty vapor barrier with string reinforcement for added strength and puncture resistance—ideal for challenging soil conditions and long-term performance under inground pools. -
Vapor Barrier Yellow – 10 Mil
High-performance under-slab moisture protection designed to meet ASTM E1745 standards. Offers excellent durability and moisture blocking without unnecessary bulk. -
VaporBlock® Vapor Barrier – 10 to 20 Mil Options
An advanced multi-layer plastic barrier engineered to block moisture, soil gas, and radon—ideal for pool projects where extra protection is a priority.
