Technology
The PolySto hygienic walls, ceilings and wall protection allows you to bring your food production facility to the highest food safety level. Thanks to the PolySto prefab system, the installation process can be shortened and run more efficiently.
Our modular and durable products can be used for renovations and new constructions with key-technologies such as CleanRock kerbs, HygiSeal joints and FRP walls and ceilings.
All PolySto products are food safe and compliant with HACCP, USDA, FDA and BRC.

CleanRock
CleanRock is the patented core material used in PolySto kerbs. The composition has been developed based on more than 30 years of experience in the food processing industry. Prefabricated CleanRock kerbs are composed of a mixture of polyester resins, quartz granulates and additives. The unique composition allows to prevent contaminations such as Salmonella and Listeria.
Advantages:
- High impact resistance
- Easy to clean, smooth and non-porous surface
- Chemical resistant, against aggressive cleaning agents and chemicals like salt, acids, blood, starch and lactic acid
- Water-resistant
- No hollow spaces
- Monolithic composition
- Repairable on-site
- Fast installation
- High bonding strength with wall panels by the use of a flexible, water resistant MS polymer glue

HygiSeal
HygiSeal is the new product for chemical welding of joints with a 1-component hybrid sealant. The HygiSeal joints between the PolySto components and the connection with floor and wall ensure a durable, seamless and fungus repellent connection that is resistant to intensive high pressure cleaning. Due to the hard and smooth surface of HygiSeal joints there is less bacterial adhesion compared to classical food safe silicones.

Hygienic FRP walls and ceilings
Fibreglass Reinforced Polyester (FRP) is a composite material consisting of polymer that is supported with glass fibers for added strength. FRP is used to build and protect structures that require additional resistance to prevent deformation and corrosion.
Our walls and ceilings from FRP offer unique features for both renovation and new construction projects.
