Stone Base Foundations and Pads

Stone base foundation with corner retaining wall

In most cases, it’s recommended that a wood floor structure rest’s on a stone base pad. However, if you’re looking for concrete to be your floor, check out our concrete foundation options. Then choose from Basic, Standard, or Signature stone foundation designs; each with better containment and longevity options. In some cases a retaining wall may be needed to extend or to level your site.

Stone Base Foundation Options

Signature Stone Base Foundation

The Signature stone base foundation pad has a border of 6” X 6” pressure-treated wood secured with ½” X 24” steel rebar and 3/8” x 10” stainless steel structural screws. They create a distinct perimeter around your structure. Geotextile fabric within the border stabilizes the stone and prevents weed growth. Stainless steel corner braces ensure that the foundation remains square and that the timbers do not pull apart over time. The Signature is our best and most durable option and has a 10-year guarantee.

Basic Stone Base Foundation
