Structural Fill Dirt

$18.95 per ton

Class 1 Structural Fill Dirt - is a 1/4 inch minus material that is guaranteed to be non expansive. That means when it gets wet, that it will not expand and damage anything installed over it. For example: pavers, concrete, asphalt, garage, garden shed, shipping containers, etc.

Class 1 Structural Fill dirt is a great multiple use material. It works great behind and under retaining walls, under artificial turf, under new concrete or asphalt, under pavers and flagstone and much more.


Class 1 Structural Fill - Overall the most versatile, best performing and least expensive material available. It is clay free. That means it's non-expansive. When it gets wet it doesn't get mucky and slimy. It dries out fast and will last a long time under, behind or around your building foundation, retaining wall, horse pens, stalls and paddocks, under poured concrete and asphalt pavement. We have many customers use it either as a base for driveway and parking areas or the driveway itself. The Class 6 Roadbases are probably better overall for that use.

You do not need to install landscaping fabric under compactable materials. Compactable materials compact to form a solid, flat surface, so weeds cannot get light and moisture to grow (germinate). Examples; any type of roadbase, (recycled asphalt, class 6 granite or recycled concrete), class 1 structural fill dirt, granite or river rock crusher fines. If you want to spend the time and money to install the fabric and pins, it doesn't hurt anything.
