GEOSYNTHETICS - DRAINAGE - CONCRETE SLAB BEDDING
						Rock-in-Roll
						Rock-in-Roll is a high tensile, low compressibility Void-Maintaining structure, which replaces free-draining aggregate underneath concrete slabs.

Rock-in-Roll is a high tensile, low compressibility Void-Maintaining structure, which replaces free-draining aggregate underneath concrete slabs. Rock-in-Roll is hydraulically equivalent to 4 inches of open-graded/free-drainable base course. It provides a supportive layer underneath the floor slab to bridge soft spots, enabling the slab to perform better by reducing the cracks and tensile stresses resulting from differential settlement. In addition, Rock-in-Roll also provides a capillary break to prevent the water from contacting the floor slabs.
