Everything You Need to Know About Drain Rock
Size and Grading

- Washed to remove fines and dust
- Type
- Rounded or angular varieties
An exposed drainage feature can remain part of an Arkansas landscape instead of disappearing under backfill. Rounded Drain Rock has a natural stone look suited to that type of visible work, while still providing open spaces for water to pass. In the Delta, where gumbo clay can retain water, those clear spaces matter around a drainage run that needs to move water away from saturated ground.
For work behind a retaining wall or below soil backfill in the Ozarks or Ouachita Mountains, angular Drain Rock has a practical advantage. The pieces interlock and retain their open drainage paths when material bears down from above. Drain Rock is cleaned by washing, leaving out dust and fine material that could fill the passageways needed for flow in a French drain or septic leach field.

Common Uses
French Drain Installation
French drains need open aggregate to move water through the trench. Drain rock's clean, open spaces carry water away from footings, basements, and low spots, helping limit water-related property damage.
Septic & Leach Field Construction
Wastewater infiltration systems, including septic drain fields, rely on drain rock as the drainage layer. The uniform, clean stone supports the health department specifications used for these installations.
Backfill for Retaining Walls
Water trapped behind a retaining wall builds hydrostatic pressure and can lead to failure. Drain rock lets water pass through the backfill so the wall can remain structurally sound.
Drainage at Foundations
Placing drain rock beside building foundations routes groundwater away from footings and basement walls. Perimeter drainage helps reduce moisture entry and the pressure that can contribute to cracks and structural damage.
Why Choose Drain Rock
Open Flow for Water
With fines and dust washed away, drain rock has open voids for water movement. That available space supports drainage throughout the system.
Lasting Flow Capacity
Rounded aggregate can settle and tighten under load, restricting the open paths water needs. The angular form of drain rock helps retain those spaces for drainage over time.
Washed & Graded Material
Drainage work calls for stone that has been washed and sorted by size. This material fits with perforated pipe, drainage fabric, and the remaining components of the system.
Structural Protection
Water buildup creates hydrostatic pressure and moisture-related damage. Drain rock moves water away from retaining walls, foundations, and other structures to help limit the repairs those conditions can cause.
