  • Tough, water-permeable paver
    Patent number: 9068299
    Abstract: A tough water-permeable paver block includes a mass of adherent coated granules with intervening contiguous channels. A method for making pavers includes selecting a gravel, heating, then evenly coating every granule with a non-rigid thermoplastics material typically at about 75 g/kg gravel, placing the hot material into a form, then cooling, optionally under imposed pressure. In one option the paver is formed from loose granules at its final resting place. The material may be provided as a coated, non-adherent gravel for heating into a coherent mass in situ. Applications include footpaths, roads and drain covers.
