2-Ton Rock Bag
Most-specified sizeThe 2-Ton Texas Tuff Rock Bag — roughly 1.13 m³ of rock in a 1.9 m sphere — is the size specified most often across our projects: heavy enough for real erosion control, light enough to place with everyday equipment.
The most-specified size for a reason
The 2-Ton is the size we ship most. It handles the broad middle of erosion-control work — streambank stabilization, light bridge and culvert scour, and shoreline revetment where wave and current energy is real but not severe — and it resists grouped currents to around 15.4 ft/s while staying placeable with the mid-range excavators most civil and marine crews already run.
That balance of performance, placement speed, and cost is why it's the most-specified unit in the lineup: heavy enough to hold a bank or shoreline through storms and boat wake, light enough to deploy without mobilizing heavy plant. When pier scour or port-toe loading climbs into higher-energy territory, step up to the 4-Ton.

Virgin polyester mesh
Raschel-weave virgin polymer — not recycled — for high UV and strong abrasion resistance in fresh and saline water, and a mesh that won't unravel if a strand is cut.
Single-point lift
Reinforced rope at a single lifting point gives operators highly controlled, precise placement — by excavator or crane, on land or in the wet.
Conforms to the bed
Filled on-site with local or supplied rock, the bag settles and conforms to scour and bed change instead of cracking like rigid concrete.

2-Ton — common questions
Why is the 2-Ton the most-specified size?
It balances armor performance against placement practicality — heavy enough for streambanks, shoreline revetment, and light-to-moderate scour, yet placeable with the mid-size equipment most crews already run. That combination makes it the volume size across our projects. For higher-energy bridge, port, and offshore work, the 4-Ton and 8-Ton step up.
How does the 2-Ton compare to the 4-Ton for streambanks?
The 2-Ton suits lighter-to-moderate flow; the 4-Ton is specified where velocities, depths, or scour potential are higher — for example bridge piers and port toes. The sizing calculator matches velocity and depth to the right unit.
Can the 2-Ton be placed underwater?
Yes. Like every Texas Tuff Rock Bag it can be filled and placed in flowing water or fully submerged, which removes the need for coffer dams and water diversion on many jobs.
