Channel Lining/Irrigation Canals

ITL Reinforced Concrete Roll®  is making channel lining and repairs far less intesive than conventional cement repairs. After rolling out, securing, and then hydrating, ITL RCR®  can be used within hours.  

ITL Reinforced Concrete Roll®  in either 7mm or 12mm thickness provides a reliable solution for most irrigation canal lining and channel lining projects, particularly with short deadlines and dipping temperatures. It provides unparalleled speed of installation and can be deployed through water. No need for rebar, forms or finshing. Simply roll it out the material following our installation instructions, hydrate and walk away. It’s that easy.

Our laboratory testing shows that very high volumes of water can run over the ITL RCR®  without scouring the base or sides of the canal. The option of building in rapids to reduce the flow is another option as ITL RCR® is a pliable and flexible product prior to hydration. Cutting and fitting ITL RCR®  around bends or penetrations within the canal is easily accomplished with minimal equipment and personnel.

Most canals have limited space for deployment which is another reason to choose ITL RCR® . The rolls can be stockpiled in a central location and deployed with a front end loader, track hoe or all terrain forklift. 

Do I need to prepare the subgrade for an existing canal?

Depends. Once ITL RCR®  is in place and hydrated, the hardened surface will contour the subgrade. You can leave existing concrete in place with larger cracks. Larger voids greater than approximately 6 inches round/square should be filled with sand or soil of some sort to bridge the gap. We do suggest vegetation be removed and larger rocks bigger than one inch be removed to provide a smoother finished surface. 

Can ripples or rapids be added to modify the water flow?

Yes, ITL RCR®  is very moldable and you can easily add rapids to modify the flow.

How difficult is it to go around bends and turns in the canal?

ITL RCR®  can easily be cut and fitted to create pie shaped pieces to smoothly transition around bends and curves. 

How would I attach to inlet or outlet gates, pipes or overflow swales?

Using stainless steel flat bar and stainless-steel anchor bolts every 6 inches, you can easily achieve a leak tight seal to existing concrete gates or pipe penetration aprons. If your canal is soil based, using a small trench also works very well. We can cut and fit smaller pieces around any penetration to create a tight seal to the penetration and main irrigation canal. ITL RCR®  is a perfect application for overflow swales. 

How do I attach ITL RCR®   to other existing liner products?

We can figure out the best method when attaching ITL RCR®  to existing concrete, plastic liners, bituminous liners, soils, etc.
