What is perma edge?
Perma Edge is forumulated to be stronger than concrete but flexible enough to withstand frost heaves and moisture. It’s over 700% more flexible than standard concrete and 40% more permeable. Perma Edge uses non-porous aggregates. Water and moisture cannot get into the base of the product.
Why do you need gravel under pavers?
Gravel allows moisture to drain, and it also absorbs ground tension. This will provide excellent support and help to hold the pavers in place without sinking in.
How far apart should pavers be?
The recommended space between the pavers is 3 mm (⅛”). I don’t expect you to measure the gap but just set them beside one another. You should stop every 4 feet and pull a string line along the laying face, with a screwdriver, adjust that face to the string line.
