Weighing in at just 1% the weight of conventional fill, POLYROCK® blocks are super fast and easy to install and virtually eliminate the lateral and vertical movement and complete bearing failure often associated with road construction on poor load bearing soils. There is also minimal settlement or long-term compression of soil layers. This can lead to substantially reduced costs for structures, foundations or ground improvements and on going maintenance costs.
POLYROCK® is suitable for numerous geotechnical applications where a dramatic reduction in vertical and/or lateral loads is required.
After 30 years of international testing and monitoring, we have found many uses for POLYROCK®. Our technical staff can provide you with any international data you need and are ready to discuss POLYROCK® EPS applications for your specific project.
POLYROCK® is a thermoplastic material that under compressive loads acts in a viscoelastic manner. POLYROCK®'s most important characteristic is its very low density. Typically ranging from 15/kgm³ to 28kg/m³, densities can be customised for specific applications.
Despite its low density POLYROCK® absorbs only a limited amount of water.
At ambient temperatures, POLYROCK® is chemically resistant to most substances naturally occurring in the ground and a wide range of other substances such as sea water, dilute acids, alkalines and bleaching agents. In high concentration, substances such as animal fats, diesel fuel, organic solvent, petrol and concentrated acids will affect the surface of POLYROCK® to varying degrees. Although such high concentrations are uncommon, POLYROCK® can be protected from chemical attack as an additional safeguard.
