Sand & Aggregate Base Delivery in Texas

Sand and aggregate base are the bedding and sub-base materials that sit beneath pipe, slab, and pavement. Soil Depot delivers cushion sand, concrete sand, and aggregate base in commercial volumes across DFW, Austin, San Antonio, and Houston, sourced to the gradation and plasticity your project requires.

Concrete sand and aggregate base material

Sand & Base, by Use

Cushion sand is the fine bedding material placed around utilities and under slabs to protect pipe and provide an even bearing layer. Concrete sand is the coarser, washed sand used in concrete mixes and as a bedding course. Aggregate base is the compactable crushed-stone or gravel layer that forms the structural sub-base under pavements and slabs.

Specified to gradation and PI

Aggregate base for roadway and pavement work is commonly specified to TxDOT Item 247 “Flexible Base,” which caps Plasticity Index by grade (Grade 1-2: PI ≤ 10, LL ≤ 40) and requires compaction to 100% of maximum dry density. We source base material to the grade your plans call for and sand to the bedding gradation your spec requires.

Sourcing & delivery

We deliver sand and base in bulk and coordinate trucking to your daily cap, with one point of contact for dispatch. For the recycled and road-surface side of base, see crushed concrete & road base.
