Gravel-Lok Porous Stone Paving is the ultimate solution for creating french drainage systems. The bonded stone surface is decorative and functional, eliminating loose messy stones. Using Cell-Tek's Load Support Grid confines open graded aggregates adding strength to the Gravel-Lok surface. The surface has a porosity which can handle up to 20 gallons per square foot every minute. Create natural stone riverbeds which function as a drainage system.
