TREMproof 250GC: Rapid-Cure Polyurethane Membrane for Green Concrete

Revolutionise Your Project Timeline with Immediate Waterproofing

TREMproof 250GC is a groundbreaking, single-component, moisture-curing polyurethane membrane designed to dramatically accelerate construction schedules. Its most significant innovation is the ability to be applied directly to "green" concrete as young as 24 hours old, eliminating the traditional waiting period of weeks or even months for the substrate to dry. This rapid-cure formula allows for backfilling or the application of landscaping within a single day, protecting projects from costly weather delays and keeping critical path activities on track. As a high-solids, low-VOC membrane tested to AS 4654.1, it delivers robust, code-compliant performance without compromising on safety or environmental standards.

Unmatched Versatility for Below-Grade and Buried Applications

TREMproof 250GC is the definitive solution for demanding below-grade and permanently wet environments. It is engineered for high-performance applications such as retaining walls, tunnels, foundation walls, and planter boxes (with an anti-root additive). Its ability to be applied in a single, thick lift of up to 3mm significantly speeds up installation on large vertical and horizontal surfaces. This versatility, combined with its exceptional resistance to hydrostatic pressure, makes it a single-membrane solution for multiple applications across a project, simplifying logistics and ensuring consistent, reliable waterproofing throughout the structure.

Superior Features for Effortless and Accurate Application

The product is designed for ease of use and precision on the job site. Being a single-component system, it requires no on-site mixing, which minimises application errors and ensures consistent quality batch after batch. The high solids content (minimum 85%) allows contractors to easily measure the wet film thickness and accurately achieve the specified dry film thickness, guaranteeing performance. This combination of a user-friendly format and high-build characteristics ensures a durable, seamless, and monolithic membrane is installed correctly the first time, reducing the risk of call-backs and ensuring long-term structural protection.

Trusted Technology for Accelerated and Resilient Construction

As part of the Tremco CPG range, TREMproof 250GC is backed by extensive research and technical support. It represents a paradigm shift in waterproofing, turning concrete curing time from a bottleneck into an opportunity for acceleration. By enabling immediate waterproofing protection, it mitigates risks associated with weather and allows subsequent trades to begin work sooner. For any project where time, resilience, and below-grade performance are critical, TREMproof 250GC provides the certified technology to build faster, smarter, and with greater confidence.

Product Limitations

  • Requires inclusion of an anti-root additive for use in planter box applications.
  • Performance on green concrete is dependent on specific site conditions; consult Tremco for project-specific advice.
  • As a moisture-curing product, application in very cold or dry conditions may slow the cure time.
