The subgrade material is the key to any good project. Without a solid foundation to build up on, things may not last as long as they should. 

When building a driveway, parking lot, patio, shed pad, or a structure, we need to have a solid foundation. You may have just excavated material and are preparing to build your long awaited project. 

Have you wondered how your subgrade and is it sound enough to not settle down the road?

If you excavated a sod or grass area, likely the subgrade is topsoil or clay material and you should start by installing and compacting a well graded material such as Roadbase or Paverbase. These materials contain various rock sizes with a maximum size of either 1 1/2" or 3/4" depending on which material you select and contain aggregate sizes all the way down to the 100 and 200's fine particles.  The materials may meet either APWA or UDOT State Specs and will be listed properly if they are spec materials. Paperwork can be provided for your inspector or engineer if necessary. 

If you build on poorly graded soil such as topsoil or clay without installing a solid base material, your driveway, patio, or walking area could face settling as the poorly graded soil settles down the road causing all your hard work to break apart and become unlevel. 

Typically a 4" - 6" layer of roadbase is recommended for the subgrade. Other projects may require thicker layers of base to meet the needs of the inspector, designer, or engineer.
