Southside 1 ½″ Round Rock
Southside 1 ½″ Round Rock is harvested from a deposit created by the combined ancestral flow of the San Benito River and the Tres Pinos Creek. It is processed through a Coarse Material Washer (scrubber) in order to remove clay and silt. The material is then conveyed to a final wash screen where undersize aggregates are removed. The final product is stockpiled, air dried, and ready for shipment.
Application: Southside 1 ½″ Round Rock has a wide variety of uses. It is well suited for septic leach fields, backfill for retaining walls, and drainage blankets. In special Portland cement concrete mixes it can be used as a coarse aggregate ingredient. Southside 1 ½″ drain rock is also utilized in landscaping applications as a decorative aggregate and as an ingredient of the Graniterock Stream Spawning Cobble blend. The aggregate color is typically light tan/gray, with spots of red, pink and purple.
