Millimetre accuracy for concrete paving
July 30, 2019
Concrete paving is now benefiting from the use of sophisticated machine control tools to deliver accuracy and high-quality surfaces Heavy use of concrete roads and runways over time will reveal any flaws in workmanship, the invasion of water, or the wear from use. Discolouration, scaling, crazing, cracking, or curling will sometimes occur due to a poor ready-mix batch, inadequate curing procedure, subgrade settlement, or improper bonding of the finish layer. Concrete surfaces are generally very durab
