Only a minimal layer (around 1%u20132 mm per side) is removed in the process to regenerate the surface. The board%u2019s geometry and dimensional accuracy are preserved, allowing it to function nearly as if it were new.Benefits for producers:%u2022 Cost-efficiency: No need for reinvestment for nearly 30 years%u2022 Product quality: Consistently high standards in masonry blocks and more%u2022 Sustainability: Lower material usage and CO2 emissions%u2022 Availability: No delays due to procurement or logistics%u2022 Environmental impact: Resource conservation and contribution to the circular economy%u2022 Productivity: No downtime from replacement proceduresHow the Wasa Grinding process worksBefore grinding begins, WAsa examines sample boards to assess:%u2022 Surface condition%u2022 Potential material removal%u2022 Board thickness and deflection%u2022 Condition of chamfers and profilesBased on this analysis, the grinding process is customized. Once approved by the customer, grinding can take place either at Wasa%u2019s facility in Germany or on-site using a mobile unit %u2013 a major advantage for internationally operating or high-capacity companies like BIA Beton.Sample boardsCost-effective and sustainable: Wasa%u2019s mobile grinding units bring the process directly to the customer.In use since 1996: The Uniplast board at BIA Beton stands out for its precision and longevity.
