Permeable Driveway Day 4Posted on August 7th, 2015 by John Foegley
The last steps for our Permeable brick driveway increase the stability of the brick surface. After the pavers are laid, perimeter edging is installed. During installation we used crushed concrete at the edges where edging would be needed so the drive has a firm foundation that the edging could be staked into. After edging installation the all dirt and chips are blown off the drive and the bricks are set into the bedding chips with a compactor. This compactor has a pad on it to protect the surface from being scratched.
Sand is not used to fill the gaps for permeable pavement because it will settle into the coarser bedding layer. Fine limestone chips were swept into the drainage gaps between the pavers to provide additional horizontal stability. After the initial sweep, the drive was blown off and the pavement compacted to settle the chips. Chips were swept into the gaps a second time to fill gaps where the chips settled. Our last step was to sweep and wash the drive and clean up the job site.
The new drive provides a unique, personalized entrance to this lake side property in Cass County Michigan.
