Challenge:
The Reinland Drain is a municipal drainage channel in southeastern Manitoba that holds and drains intermittent water flow from regional spring melt/breakup and peak discharge events. Failing rip rap rock from heavy run-off flows had been causing reoccurring erosion of the channel slopes—an ongoing problem spanning 75 years.
Achievement:
To address severe erosion along the Reinland Drain, the RM of Stanley engaged Stantec and implemented Titan’s ARMORMAX® system—an advanced, long-term solution combining HPTRMs, earth anchors, and gabion baskets—successfully installed in winter conditions and later hydroseeded to promote soil stabilization and vegetation.
Product Used:
ARMORMAX®
Location: Southeastern Manitoba
Project Type: Product Supply & Installation
Product Used: ARMORMAX® with Gabion Baskets
Challenge
The Reinland Drain is a municipal drainage channel in southeastern Manitoba that holds and drains intermittent water flow from regional spring melt/breakup and peak discharge events. Failing rip rap rock from heavy run-off flows had been causing reoccurring erosion of the channel slopes—an ongoing problem spanning 75 years.
Titan Solution
The RM of Stanley was looking for a superior longer-term erosion control solution and engaged Stantec’s engineering services. After a series of consultations with Stantec, Titan proposed the ARMORMAX® Engineered Earth Armoring System which is an advanced flexible armoring solution designed specifically for severe erosion challenges.
Proven to provide up to 75 years of design life ARMORMAX® consists of PYRAMAT®, woven three-dimensional High-Performance Turf Reinforcement Mats (HPTRM) with X3® fiber technology, and Engineered Earth Anchors (EEAs). In this application gabion baskets filled with rock were placed on the base floor of the channel, and a total of 38,000 m² of ARMORMAX® was installed on the channel slopes.
Being a winter installation, the extreme cold conditions made it challenging to penetrate the frozen ground with the system’s B1 Anchors and 5mm 18” spikes. Our installation crew quickly adapted and switched to 10mm- 12” pins which were within the acceptable specification range and allowed for a successful installation. The channel was later hydro seeded by another contractor to ensure vegetative growth through the matts—critical to helping lock soil in place and protect against hydraulic stresses.
ARMORMAX® Engineered Earth Armoring Solution is the most advanced flexible armoring technology available for severe erosion and surficial slope stability challenges.
Achievement
After nearly one year, outstanding vegetation growth was observed, and the site continues to be monitore
d. As vegetation increases and deeper root structures develop, the system is expected to solidify and perform at its peak. Four years later, the ARMORMAX® system has proven its durability, withstanding several harsh Manitoba winters. Notably, during the heavy snow and ice melt of winter 2021/2022, which caused significant spring flooding and high water flow, the channel section reinforced with ARMORMAX® performed exceptionally well. The gabion mats on the channel floor functioned as intended, and sedimentation has supported further vegetation growth. In contrast, failure was observed in sections of the channel where ARMORMAX® was not installed.
