Do's and Don'ts of Paver Installation: Step 2 of 3
The recommendation for over preparation is that the base material should extend past the paved edge an equal distance of the base depth. For example, if your patio is 20 feet by 10 feet and you are installing 6 inches of granular material as a base, then you must excavate an area 11 feet (10' + 6" + 6") by 21 feet (20' + 6" + 6").
Driveway Repair and Replacement: Options & Costs
Cost: Crushed stone and gravel costs around $1 per square foot for a 2-in. layer. Recommendations: When a fill coat of pea gravel is necessary to fill in ruts, be sure to redress the entire driveway for consistency since stone size and color can vary depending on the source. For new gravel driveways, use 3/4-minus stone for stability.
