Waterproof and Water Resistance Explained

In commercial environments, flooring must perform as well as it looks. GH Commercial offers a range of hard flooring solutions engineered with varying levels of water resistance and waterproof technology, designed to support durability, hygiene and long-term performance across demanding applications. From protection against everyday moisture exposure to advanced systems developed for high-risk wet areas, our solutions provide confidence in specification without compromising on design intent, aesthetic quality or project requirements.



Selected GH Commercial hybrid flooring ranges are Codemark certified for use in internal wet areas, supporting specification in environments where moisture management and compliance are critical. This independent certification is underpinned by rigorous laboratory testing and third-party assessment, verifying that both the product construction and installation system meet the requirements for waterproof performance in appropriate commercial applications.*

UNICLIC® LOCKING SYSTEM
Uniclic® is a precision-engineered, watertight installation system that allows hybrid flooring to be installed without adhesive. The advanced tongue-and-groove profile enables planks to securely click together, forming tight, reliable joints designed to resist moisture penetration and support efficient installation across commercial projects.

WATERPROOF SURFACE
A factory-applied waterproof coating creates a sealed surface layer, forming an effective barrier against moisture. This protective layer helps prevent water penetration and supports resistance to spills, stains and routine surface moisture exposure commonly encountered in commercial environments.

WATERPROOF CORE
The waterproof core is constructed from a dense, non-porous material engineered to resist moisture absorption. This stable core structure acts as a robust barrier against water, reducing the risk of swelling or structural degradation and supporting consistent performance in moisture-prone areas over the life of the floor.

*Please refer to the Installation Instructions available on our website for full details of the requirements for installation of Metropol hybrid flooring in wet areas. Codemark certification relates to the certification of a ‘performance solution’ for the purposes of the Building Code of Australia comprising both hybrid flooring and perimeter sealing products as detailed in the Installation Instructions. Please note that GH Commercial Metropol hybrid flooring is not suitable for installation in wet areas with floor wastes or falls to waste


    Engineered with an advanced waterproof core, GH Commercial waterproof flooring solutions are designed to go beyond standard spill protection, helping to prevent moisture ingress and support reliable performance in demanding commercial applications. This construction provides added confidence in spaces subject to routine surface moisture, spills and cleaning regimes.

    UNICLIC® LOCKING SYSTEM
    Uniclic® is a precision-engineered installation system that enables hybrid and laminate flooring to be installed without adhesive. The watertight locking profile is designed to form tight, secure joints, helping to limit moisture penetration at plank connections while supporting efficient installation across commercial projects.

    WATERPROOF SURFACE
    A factory-applied waterproof coating creates a sealed surface layer that acts as a protective barrier against moisture. This surface treatment helps resist water penetration while supporting protection against spills, stains and everyday surface moisture commonly encountered in commercial environments.

    WATERPROOF CORE
    The waterproof core is constructed from a dense, non-porous material engineered to resist moisture absorption. This stable core structure provides a dependable barrier against water, helping to minimise the risk of damage from spills or humidity and supporting long-term performance and dimensional stability in moisture-prone areas.


      GH Commercial water-resistant flooring solutions are designed to manage incidental moisture and everyday spills in low-risk commercial environments. Suitable for areas where occasional liquid exposure may occur, this level of protection supports practical performance while maintaining design flexibility across a range of commercial applications.

      UNICLIC® LOCKING SYSTEM
      Uniclic® is a precision-engineered installation system that allows hybrid and laminate flooring to be installed without adhesive. The accurately machined tongue-and-groove profile enables planks to click together securely, helping to reduce the risk of moisture penetration at joints when exposed to minor, incidental spills.

      WATER-RESISTANT SURFACE
      A factory-applied surface coating provides resistance to light moisture exposure by forming a protective barrier over the product. This surface treatment helps manage minor spills and everyday surface moisture, supporting durability in appropriate low-exposure commercial settings.
