Mining and Mineral Processing

RCR® for Water Management,
Erosion Protection,
Containment, and More

 

Inland Tarp & Liner’s Reinforced Concrete Roll® (RCR®) is a versatile geosynthetic cementitious composite mat (GCCM) product with multiple applications for mining and mineral processing operations. After being unrolled, RCR® is anchored and hydrated. Installation saves cost and time when compared to traditional concrete pours, and once cured, RCR® is set as a durable, long-term surface.

RCR® can be installed for
these and other uses:

Mining Operations

Water management

Erosion protection

Containment

Infrastructure repair

Mineral Processing

Channels and ditch lining

Pipe underlayment

Secondary containment

Slope erosion protection

For Mining Operations

There are multiple use cases for Reinforced Concrete Roll® in the mining industry.

Water Management

A primary GCCM use case for mining operations is water management as clean water is directed for use and contaminated water is addressed. Water flow has little effect on RCR®, and the product has application as a liner for culverts, drainage channels, swales, and more.

Erosion Protection

RCR® can guard surfaces against rain, moving water, and runoff scour. Whether used as a ditch or channel liner, on basin slopes or embankments, under piping, or in other ways, RCR® is a durable, cementitious erosion protection solution. According to our laboratory testing, RCR® can handle high levels of water velocity and shear without measurable soil loss.

Containment

Reinforced Concrete Roll® can be applied for both freshwater and mining waste containment. Uses for freshwater containment include lining ponds, holding basins, dams, and berms. 

RCR® is a sturdy and low-permeability product, and in many cases can act as the containment lining, providing armor and erosion protection. For hazardous material containment that requires complete seepage control, RCR® can work alongside a geomembrane lining, providing protection for the liner and against erosion.  

Waste containment uses of RCR® include confining mining process fluids, drainage, and tailings. To help prevent water and oxygen from contacting contained waste, RCR® can be used to cap ponds or impoundments.

Infrastructure Repair

As a cementitious product that unrolls, RCR® can be installed on existing concrete to provide stabilization at a lower cost than employing a traditional concrete-pour approach.

 

For mining infrastructure repair, RCR® can be used for resurfacing ditches, spillways, outfalls, culverts, channel embankments, and for repairing containment structures and storage tank bases.

For Mineral Processing

In addition to uses for mining operations, RCR® can be installed for mineral processing applications.

Lining Channels and Ditches

Applied to channels or ditches, RCR® provides a sturdy, erosion-resistant liner for mineral processing purposes. RCR® installs faster than traditional concrete pours and can be conformed to curves in channel and ditch profiles. It can also help with weed suppression.

Pipe Underlayment

As an underlayment, RCR® can help prevent pipe joint failure and sagging by holding soil in place and stopping erosion from pipe leaks or storm runoff. Also, RCR® unrolls in large sections, aiding in quick installation.

Secondary Containment

RCR® provides a sturdy barrier for overflow, leak, and spill containment, and can be deployed as a protective armour for geomembrane liners. A sturdy and flexible cementitious product, RCR® deploys without forms and can be fit around differing contours.

Slope Erosion Protection

For mining and mineral processing operations, RCR® provides a sturdy and versatile slope erosion solution. RCR® can be installed on slopes that run gradually or at a steep angle, providing armoring that is resistant to ultraviolet rays, fire, cold temperatures, and adverse weather conditions.

Why RCR® for Mining and
Mineral Processing

Ease of installation, durability, and water and chemical resistance are all reasons for choosing RCR® for mining and mineral processing jobs.

Ease of Installation

RCR® installation does not require cement trucks, mixing, use of forms, or rebar. The product unrolls from a central beam and can be installed with less time and money than with conventional cement pour installations.

 

 

Durability

Unlike other erosion-protection products, RCR® does not need to be regularly replaced.

RCR® has a 30-year pro-rated warranty, requires little to no upkeep, and can handle high-volume rain and snowmelt.

 

 

Water and Chemical Resistance

RCR® has high resistance to water and many chemicals. Please contact our team for information on RCR® applications.


About Reinforced Concrete Roll®

A cementitious composite product, RCR® has a top geotextile layer, a center layer of dry concrete powder, and a bottom geotextile layer. 

There is a 7mm thick RCR® product (RCR-7®) and a 12 mm thick RCR® product (RCR-12®). Both are offered in a standard roll size of 5m wide x 20m long, which is about 16 ft. 4 in. x 65 ft. 7 in. Ask our team about custom sizes.


A standard roll of RCR-7® weighs 1,700 lbs., and a standard roll of RCR-12® weighs 2,800 lbs.

Mining Application/Erosion
Control Case Study

RCR® as a Pipe Underlayment at a Florida Phosphate Mine

Overview

RCR-12® was used for erosion protection under large-diameter casing pipe installed on sloped areas of a phosphate mine.

Project Goal

Implement a slope conveyance system to handle phosphate mine water flows and prevent soil erosion under large-diameter casing pipe.

Why RCR® for the Job

Various erosion control options were considered for this job. After assessment of the site’s conditions and requirements for installation, RCR-12® was selected.

Aspects of the Installation

Workers deployed RCR-12® with an excavator. The installation required product overlaps and anchoring, which were conducted without heavy equipment operators, specialized training, or complex tools. Installation occurred on soft, sandy subgrade.

Completion

The RCR-12® underlayment was successfully installed, with the unrolling format requiring less labor than would have been required with other installation approaches.

Additional Case Studies

RCR-7® was used as a tailings pond liner at an Arizona mine site. Select the link below for the case study.

Erosion Control Q&A

No. The non-woven geotextile that holds the cement in place will eventually degrade under constant UV exposure, but the concrete will last for many years. We offer a 30-year pro-rated warranty.

Yes. Hairline cracks, which cannot be seen due to fibers covering the concrete, will occur. RCR® will not develop large cracks because the fibers keep the concrete from separating.

RCR® can be applied on virtually any slope, even for almost vertical installation. The top anchoring can be designed based on the slope and subgrade. Consult with our team concerning specific slope applications.
