Yes. RCR® is very capable of withstanding water flow, even constant water flow.
RCR® has excellent performance in most water applications and is PN EN 12467:2016-8 5.4.5-6 standard compliant.

Spillway and Outfall Protection
A sturdy, protective solution for spillways and outfalls
Reinforced Concrete Roll (RCR®) from Inland Tarp & Liner is a strong and versatile solution for protecting both spillways and outfalls. RCR® is a geosynthetic cementitious composite mat (GCCM) that unrolls and, when hydrated and cured, forms a strong protective barrier.
Spillways and Outfalls
Spillways and outfalls are used in situations involving stored water (including ponds and reservoirs), stormwater management, flood control, and water discharge, such as disbursement of wastewater.
Multiple sectors have use cases for spillways and outfalls as they perform their roles in discharge regulation and flood control/overflow diversion.
Why RCR® for Spillways and Outfalls
Reasons to select RCR® for spillways and outfalls include durability, versatility, erosion protection, vegetation control, and ease of installation.
Durability
RCR® is a durable GCCM resistant to the erosion effects of water flow, hot and cold temperatures, and adverse weather conditions.
Versatility
A versatile product, RCR® can be installed around corners, on slopes, and fit to curves, following the outline of even complex spillway and outfall arrangements.
Erosion Protection
As water flow is concentrated at spillways and outflows, erosion can become a primary concern at those points of a water system. RCR® forms a strong barrier to protect against soil erosion.
Vegetation Control
One benefit of our unrolled concrete is the suppression of vegetation growth at the point of channel discharge.
Ease of Installation
Off-loaded with straps, RCR® is applied with a spreader bar that has a pipe through the center. No rebar or forms are needed. A blade can be used to cut the product to fit the project, and pieces of RCR® can be securely connected by torch welding.
RCR® Application Across Industries
RCR® is a cementitious product that can be applied to protect spillways and outfalls used for multiple reasons in various sectors, some of which are presented in the following chart.

Drainage Ditch Erosion Case Study
RCR-12® for a Long-term Solution in Louisiana
Overview
During a five-year period, Pointe Coupee Parish in Louisiana tried multiple ways to solve an erosion issue affecting a wide-mouth drainage ditch, including the application of riprap and erosion-control blankets. Inland Tarp & Liner teamed with infrastructure support company QSM to address this problem.
Project Goal
Stop the widening of a drainage ditch causing termination pond damage and property damage and loss with a permanent and cost-effective solution that would protect the channel and outfall.
Why RCR® for the Job
This project and RCR-12® aligned due to the product’s ability to handle water flow efficiently and control erosion effectively.
RCR-12® was selected as a long-lasting solution that was more affordable than the considered alternatives of articulated concrete block, traditional concrete, and fabric-formed concrete.
Aspects of the Installation
The municipality was able to install RCR-12® for this project instead of outsourcing the installation, representing one way that selecting RCR® can lead to savings for municipal projects.
Quick product deployment helped to reduce the installation timeline.
Completion
The installation of 5,400 square feet was completed in three days, including time to prepare the site. After RCR-12® was installed, a sprinkler system was used to hydrate the material.
RCR® Product Q&A
Can RCR® withstand water flow?
In what types of climates can RCR® be installed?
RCR® can be applied in and performs well in both cold and hot climates. Humidity, temperature, and sunlight can impact curing times, however. Installation of RCR® is not recommended in below-freezing conditions, and additional water may be required for proper product curing if installed in extreme heat.
After installation, RCR® is resistant to both heat and cold.
Can pieces of RCR® be connected?
Yes. Two pieces of RCR® can be connected. We recommend overlapping the pieces about 6 inches (150mm) and welding the pieces using a torch.
The cost for RCR® depends on project scope. Contact us for a quote customized to your job.
