Concrete Form Liners

Concrete formliners are molding tools used to imprint a concrete surface with textures and patterns. Once the concrete sets, the liner is stripped, and the exposed, hardened surface reflects the desired pattern. Formliner patterns can look like anything, from real rock to detailed graphics, or even photographs. They make concrete walls more attractive near highways, neighborhoods, parks, and more. Different types of materials exist to produce formliners of various shapes and sizes. Choosing a formliner material will depend on your expected number of uses, desired finish, and project size.

For single-use, high impact polystyrene plastic is a simple solution.
For multi-use, when 2 to 10 pulls are needed, ABS plastic is a more durable option. ABS is a thermoplastic material that typically uses pure stone as a master.
For multi-reuse, when 10 or more pulls are needed, polyurethane rubber is a high-end option. Urethane outperforms most other materials due to its durability and machinability.

Polyurethane provides you with advanced options for creating a high-quality formliner. When poured, urethane is very versatile in the deep patterns and details it can generate. It copies extreme detail from a master and transfers it onto the concrete where detailed shapes, contours, or curves are desired. Polyurethane will cure in place without heat or expensive equipment, while plastic typically requires an oven and vacuum machine to pull it onto a form. Pouring polyurethane also gives you control to change the thickness of the liner. It becomes more durable or less depending on thickness, which can also affect the final cost.

VFI manufactures MDI and TDI urethane rubbers for large or small-scale formliner projects, whether cast-in-place, tilt-up, or precast. TDI rubber is an industry-standard for formliners, offering premium properties and low moisture sensitivity. Our TDI rubbers with hardnesses ranging from 50A–70A are great when advanced detail is required on the concrete. Our 70A-90A TDIs are also great for form lining if simple detail is needed. These formliners can be durable when poured thick at a lower hardness or tough when poured thin at a higher hardness. Another option is our cost-effective 70A and 80A MDI rubbers with similar properties, but they must be used in a controlled, high-production environment.
