Those greens that had low profile channels need to ensure the difference in levels of green and bank conform to the Law of bowls. This specially profiled, steel grid reinforced concrete slab fits over most known units. Attached with “concrete super glue” which adheres with a stronger bond than the original concrete. Rear face protection required and recommended to cover joint of the two units. Benefits are: no loss of playing time, fitted any time of year and of course, the Green is not disturbed. Unit weight 35kg. Priced per standard 39m sq. Our carriage price is £POA as is dependant on location.
