Top Waterproof Subfloors: Why Platon & DELTA®-FL Lead for Basements

Posted by Spycor Building on May 14th 2025

                                                   

Basements are notorious for moisture issues. Water seeping through concrete slabs can lead to warped flooring, mold growth, musty odors, and even structural damage. Without proper moisture management, your beautiful new floors could be ruined in no time. A high-quality subfloor system acts as a protective barrier, creating a ventilated air gap that:

  • Prevents moisture damage: Keeps water vapor from reaching your flooring.
  • Insulates against cold: Makes your basement warmer and more energy-efficient.
  • Extends flooring lifespan: Protects hardwood, laminate, vinyl, or carpet from wear.
  • Improves air quality: Reduces mold and mildew for a healthier home.

Spycor Building's Platon and DELTA®-FL subfloor systems are designed to address these challenges, making them ideal for basements in flood-prone areas, rainy regions, or any home with a concrete slab.

CertainTeed Platon: The Ultimate Waterproofing Solution

                                   

The CertainTeed Platon Plastic Concrete Subfloor is a game-changer for basement renovations. Made from durable, high-density polyethylene (HDPE), this 24-mil thick membrane features a unique dimpled design that creates an air gap between the concrete and your finished floor. Here’s why it’s a top choice:

  • Superior moisture protection: The air gap equalizes vapor pressure, allowing concrete to dry while keeping flooring safe.
  • Versatile compatibility: Works with hardwood, laminate, vinyl, carpet, and even radiant heat systems.
  • Easy installation: Lightweight and DIY-friendly, saving you time and labor costs.
  • Durable and long-lasting: Built to withstand heavy foot traffic and resist damage.

With Platon, you can install flooring on fresh concrete as soon as it’s walkable, speeding up your renovation timeline. It’s the perfect solution for homeowners looking to create a dry, comfortable basement without breaking the bank.
