What is Resin Rock?
Resin Rock is a purpose made substrate engineered exclusively for the application of microcement finishes. It solves the common issues found with traditional materials like foam boards, plastic shower trays, and timber, including movement, delamination and poor adhesion.
Whether you're a microcement applicator, interior designer, contractor or homeowner, Resin Rock delivers a stable, high strength, pre primed base that ensures your finish performs as beautifully as it looks.
Industry-leading benefits
Outperforms traditional materials
XPS foam boards, plastic shower trays, and timber are prone to moving, delaminating, or losing adhesion and collapsing over time. Engineered exclusively for microcement coatings, Resin Rock doesn’t face these issues, avoiding a one-size-fits-all approach.
Saves time on installation
Resin Rock products are pre-primed, with a finish that bonds to microcement straightaway. No extra prep needed.
Applying the microcement coating onsite gives you the stunning colour you see on our shower trays, sinks, and all our microcement-ready products.
High durability and compatibility
With high compressive strength, you can rest assured you’re getting a stable, durable base, tested with leading UK and European microcement coating brands for full system compatibility.
Purpose-made, not repurposed
Leave behind absorbent, retrofitted materials. Not adapted from foam, wood or glass-reinforced plastic, Resin Rock is a raw material developed specifically for microcement - and is 100% waterproof.

Main applications
Resin Rock is suited for both commercial and residential use. Whether you’re designing a wetroom, giving a commercial kitchen sink a lift, or installing spa loungers for a group of hotels, products made with Resin Rock deliver a level of quality you won’t find elsewhere.
The raw material comes ready to go and is single-cast, meaning there’s only one element for the microcement to be applied to, making it less vulnerable during installation.
We also produce items to bespoke sizes, specifications, and drainage options. Simply contact us to request a customised system.
