Flexamat - The Best Permanent Erosion Solution

Levee Armoring with Flexamat Plus. The site was located off the Intracoastal Waterway, and the material was delivered and installed by the contractor's barges. Flexamat Plus was specified because of the high clay soil content and the crane grass that grows along the levees. The Flexamat Plus has a Curlex wood fiber blanket to provide soil moisture along with a Permanent Turf Reinforcement Blanket to provide permanent erosion control. These underlayments are flexible enough to work with Flexamat and will allow the larger crane grass sprouts to grow between the blocks.

The design team for a substation expansion needed a solution for slope erosion around a substation in a desert area. The engineers required a product that could withstand the arid environment and stop slope erosion during heavy rain events. Erosion on the slopes surrounding the substation would lead to sediment deposition within the transformers, a risk that had to be permanently mitigated. The concrete block mat, Flexamat 10-NW, was selected to armor the slopes surrounding the substation. Motz Enterprises, Inc. supplied 310 custom length rolls. The tied concrete block mat rolls were pre-cut in custom lengths at the manufacturing plant. The concrete mat lengths matched the slope lengths onsite. Each roll was marked with it's designated number and roll size. Motz Enterprises coordinated the deliveries with the contractor so that the concrete mats arrived in the sequence of installation.

This wastewater treatment plant (WWTP) was originally designed with a flexible membrane liner (FML). However, this design did not meet NPDES discharge limits set by the Department of Health and Environment. It was determined that vegetated soil side slopes would improve water quality. Flexamat Plus was selected by the design team to permanently armor the soil side slopes while allowing vegetation growth. 94,000 square feet of Flexamat Plus was installed over five days to armor the retention basins at waste water treatment facility including - 187 - 16’ x 18’ rolls & 125 - 16’ x 20’ rolls The City Engineer was impressed with the quick vegetation establishment within the concrete block mat. The City Maintenance Department was pleased to discover that wildlife could now safely exit basins without becoming trapped. No longer did maintenance teams need to remove carcasses of trapped wildlife. The Flexamat armored side slopes are maintained with the department's commercial mowing equipment.

In order to facilitate future development within an existing floodplain, the City worked with the Flood Control District to develop a comprehensive Area Drainage Master Plan Report. The study area was approximately 85 square miles located within the Mohave Desert. The results of the study were used as a planning tool and as input to the design of potential future drainage infrastructure and flood mitigation measures that are appropriate for the physical environment for both existing and future development. Based upon this data, a plan was developed to create a flood control channel to open flood plain land for future development. This required a 4800' long channel to be constructed. The Flood District engineers needed permanent erosion control for the channel and sought an alternative to rock rip rap. The engineers did not view rock rip rap as a permanent solution, knowing that the rock would often displace after large rain events and be an ongoing maintenance issue for the Flood District. The project location in the Mojave Desert created unique design challenges, this area is known as one of the harshest climates in the world. Due to the extreme climate, Flood District engineers needed a product that would withstand these tough conditions. A cellular confinement system was specified to armor the flood channel from future erosion, also known as geocells. Typical cellular confinement systems are geosynthetics made with ultrasonically welded high-density polyethylene (HDPE) strips or novel polymeric alloy (NPA)—and expanded on-site to form a honeycomb-like structure—and filled with sand, soil, rock, gravel or concrete. The Flood District engineers specified Flexamat 10-NW as an alternative to the cellular confinement/geocell. Flexamat 10-NW is a tied concrete block erosion control mat. This concrete erosion mat includes a 10-ounce non-woven geotextile underlayment. The low bidding contractor for this project determined Flexamat 10-NW would be a significant labor and time savings compared to installing the cellular confinement/geocell system. The Flexamat concrete erosion mat was manufactured on the project site, greatly reducing transportation cost.

These are 8'x50' Flexamat rolls installed on a 2:1 channel slope. Recyclex TRM was installed as an underlayment at the toe, and an Curlex ECB was installed as the normal slope underlayment for seed and rill protection.
