SteinTec tuffbed® 2-pack is a high performance, naturally pure hydraulically bonding mortar. Bedding depths of between 20 mm to 70 mm may be placed in a single layer. Greater depths may be accommodated by placing successive layers of SteinTec tuffbed® 2-pack as a screed bed.
SteinTec tuffbed® 2-pack is shrinkage compensated, reducing the risks of failure associated with building permanent stress into new pavement structures, the inevitable result of excessive shrinkage.
The Elastic Modulus of SteinTec tuffbed® 2-pack is optimised to provide the correct supporting stiffness whilst continually absorbing the thermal and dynamic stresses inherent in all pavement structures. tuffbed® 2-pack complies with or exceeds the performance requirements of BS7533-7 & BS7533-12.
