THE EFFICIENT ROCKSHIELD
ROCKARMOUR™ IS THE LATEST OFFERING IN ROCKSHIELD TECHNOLOGY FOR PIPELINE PROTECTION.
PROTECTION EFFICIENCY
ROCKARMOUR™ PRO – EXCELLING IN PIPELINE PROTECTION AND IMPACT RESISTANCE.
​
​
ROCKARMOUR™ PRO is made of a perforated low-density polyethylene liner. It composes of a multilayer polyethylene liner that is perforated on 1” centers.
It protects coated pipe from damage from stones during backfill operations, and it allows cathodic protection current to flow protecting the pipe from corrosion.

INSTALLATION EFFICIENCY
NO TAPE REQUIRED
ROCKARMOUR™ PRO for pipe diameters ≥ 24” comes in lengths up to 340 feet and with enough material to overlap approximately 6” on the bottom with a “cigarette” style wrap around the pipe. The width of each roll varies according to the pipeline’s diameter, eliminating the need to cut on site.
EASY INSTALLATION
ROCKARMOUR™ PRO has definite cost efficiency advantages in comparison with other products. For pipe diameters ≥ 24”, rolls are placed on a special telescoping spreader bar designed to allow the rock shield to be easily applied directly over the pipe with on-site construction equipment, minimizing handling time and job site labor.
SAVE ON LABOR COSTS
With ROCKARMOUR™ PRO contractors may save as much as 75% in labor costs and maintain or exceed the run rate required to stay ahead in the field, giving you more miles for less.

ROCKARMOUR™ PRO for pipes ≤ 20” diameters, come in standard shorter lengths of 30 ft., 40 ft., and 50 ft.
Custom lengths and widths are available upon request
​
Pipe Diameter ≤ 20 inches: Rolls are typically 30 - 50 ft. in length but custom lengths can be delivered on request.
INSTALLATION FOR
PIPE WIDTH ≤ 20"
​
-
Place roll of ROCKARMOUR™ PRO on to top of pipe.
-
Unroll the ROCKARMOUR™ PRO parallel onto the pipe.
-
Wrap the ROCKARMOUR™ PRO around the pipe over lapping the edges.
-
Begin inserting connector heads on the support ties.
-
Position the ties on top of the pipe and begin tightening the ROCKARMOUR™ PRO onto the pipe.
​
Pipe Diameter ≥ 24 inches: Rolls are typically 340 ft. in length but custom lengths can be delivered on request. These longer rolls are installed using a special assembly that allows the roll to be installed on the center of the roll. This results in a reduced labor process and faster installation.
INSTALLATION FOR
PIPE WIDTH ≥ 24"
​
-
Place roll of ROCKARMOUR™ PRO on to roll assembly to prepare for installation.
-
Unroll the ROCKARMOUR™ PRO parallel onto the pipe.
-
Wrap the ROCKARMOUR™ PRO around the pipe over lapping the edges.
-
Begin inserting connector heads on the support ties.
-
Position the ties on top of the pipe and begin tightening the ROCKARMOUR™ PRO onto the pipe.
TECHNICAL DATA
*Rocks of varying size were combined to create an impact force of 50 and 75 ft. lbs. of force drops from a distance of 6 ft. The pipe coupons were coated with 0.02” thick bonded coating and were covered with one wrap of 80 mil ROCKARMOUR™ PRO protective wrap.
