Perm Chip is the perfect choice for permeable paving stone installations, both as a bedding course and as a joint filler. It is a granite aggregate that is an extremely hard material and easily withstands the rigors of freeze/thaw cycles. It will not break down, helping to control runoff for years to come. PermChip is the right choice for both residential and commercial applications, including driveways, patios, walkways and parking lots.
