The Parkdecor gravel surface should only be compacted using a roller weighing between approximately 50 kg (a garden roller filled with water) and 750 kg (with the vibration function switched off), depending on the size, purpose and requirements of the project. Vibrating plates or vibratory rammers must not be used. In areas inaccessible to a roller (corners, next to building walls and low walls, under benches, etc.), the layer must be compacted using, for example, a plank, a beam, a brick, etc.
