Our reinforced concrete roll product provides a cost-effective and time-saving solution for canal and ditch lining installation and repair. ITL Reinforced Concrete Roll® (RCR®) is an excellent option for most canal and ditch irrigation applications, particularly those with short installation deadlines, cold-weather conditions, and limited space for deployment.
RCR® is available in a ~16' 4" width, which is extremely beneficial when used for canal and ditch lining applications. Wide rolls reduce installation time and waste in these projects.
Ease of Installation
RCR® provides unparalleled speed of installation. After being unrolled, secured, and hydrated, the RCR® can be used within hours. There is no need for rebar, forms, or finishing. Simply unroll the material according to the provided installation instructions and hydrate. Installation can be accomplished with minimal equipment and personnel.
A secure and high-strength product, RCR® can withstand very high volumes of rain or snowmelt without becoming damaged. With proper anchoring, RCR® has the strength and pliability to provide erosion protection for extreme slope conditions.
Less-Intensive Repair,
Long-Term Quality
RCR can be used as an initial canal or ditch lining, but also as a quality option for repairing existing canals. Repairing an established ditch or canal using RCR may require less intensive site preparation, out-of-use time, and be less expensive than traditional concrete repair.
Configuration Options
Pliable and flexible prior to hydration, RCR® can be cut and formed around bends or penetrations within a canal or ditch. We have installed RCR® to reduce velocity; however, we would need to know more about your project and specific needs to determine if the application would be suitable for this purpose.
Handling of Water
Our laboratory testing shows that RCR® can handle very high water velocity and shear without measurable soil loss.
Deployment
Most canals have limited space for deployment, which is another reason to choose RCR®. The concrete rolls can be stockpiled in a central location and deployed with a front-end loader, track hoe, or all-terrain forklift.
Composite concrete liners for canals and ditches are available from Inland Tarp & Liner. Trust us for efficient solutions, whether for new installations or repairs.
Overcoming Installation and Timeframe Challenges in California
An RCR®-lined canal was installed to connect a newly placed underground pipe to an existing open-style canal. The irrigation system serves a California farming community near the Mexico border.
Project Goal
Tie a new canal to an existing structure in five days or less.
Why RCR® for the Job
Given a shorter section with two curves, using traditional concrete would have been more costly and time-intensive than deploying RCR®, which would have delayed the canal's return to use. Also, compared to RCR®, other geomembrane options would have been more susceptible to vandalism and animal damage.
Aspects of the Installation
For this installation, RCR® application was from the upstream side of the canal, an approach that differs from typical canal applications and that gave seam security extra attention.
RCR® was configured to negotiate difficult angles in the transition to an existing concrete vault.
Completion
Completing the RCR® application took three days; hydration in the highly dry conditions took a fourth day.

Do I need to prepare the subgrade of an existing canal before RCR® is installed?
Once RCR® is in place and hydrated, the hardened surface will contour to the subgrade.
The subgrade will need to be well compacted. You may leave existing concrete with larger cracks in place. Voids greater than approximately 2 inches around / square should be filled (with sand, soil, etc.) to bridge the gap. We suggest removing vegetation and rocks larger than 1 inch to provide a smoother finished surface.
How difficult is it for RCR® to go around bends and turns in a canal or ditch?
RCR® can easily be cut and fitted for a smooth transition around bends and curves.
Can RCR® be attached to existing liner products?
Yes. Our team can consult about the best method for attaching RCR® to existing concrete, plastic liners, bituminous liners, soils, etc.
How does constant water flow affect RCR®?
Most water applications have little to no effect on RCR®.
