Task

Due to the shrinkage process that takes place during the hydration and drying phase, concrete is subject to a reduction in volume. Therefore, on concretes younger than six months, rigid coverings should not be laid with conventional products. Otherwise, the resulting stresses can result in sustainable composite faults and pavement detachment if occupied too quickly. Depending on the age of the concrete, we recommend different, deformable adhesive mortar systems and/or decoupling, which can safely absorb any changes in shape from the substrate.
