Revitalizing Glen Garden Drive’s Bar Ditch Using Concrete Canvas
What ditch lining solutions did Ferguson Waterworks provide the City of Fort Worth in order to prevent erosion? We help establish a durable, low-maintenance, and cost-effective approach for ditch revitalization projects in San Antonio, Texas.
Project Overview
The bar ditch lining Glen Garden Drive in the city of Fort Worth, Texas did not account for the additional water drainage from a nearby artillery plant. It is situated on a 4:1 downhill slope and spans roughly 160 LF. Furthermore, the plant’s 6-7’ flume sat near the top of the ditch. Because the ditch design did not account for this additional flow, a long-term drainage solution was necessary to prevent erosion.
The site was overgrown, ungraded, and in disarray. In addition, it was littered with leftover rock and debris from previous erosion control attempts.
Challenge Goals
Ultimately, the goal was to revitalize the bar ditch and ensure it supports significant channel flow from the top of the slope without erosion. In addition, the final result needed to be aesthetically pleasing. Furthermore, the city intended to use this undertaking as a model for future drainage projects in order to reduce costs related to installation, materials, time, and maintenance.
Solution
Firstly, the team removed the existing, unnecessary materials from previous patch jobs. Not only did this provide a clean working surface but also it ensured an aesthetically pleasing finish. Then, in collaboration with Concrete Canvas and the City of Fort Worth, we began installing the concrete fabric ditch lining.
How was the Concrete Canvas installed as ditch lining?
After Ferguson Waterworks delivered the concrete fabric on site, the installation crew overlapped pre-cut sections of it down the channel. The ditch liner followed the flow direction – similar to applying shingles on a roof. Using Elephant Armor, a fiber-reinforced, quick-setting concrete, the Concrete Canvas intimately contacted the existing flume and successfully terminated the system at its entry and exit points. Lastly, the concrete fabric was hydrated
Vegetating bar ditch slopes provides an appealing finish.
After installing the concrete ditch liner, the team applied hydroseed to the side slopes. Then, the seeds were protected with an erosion control blanket until adequate vegetation was achieved.
Results
With great success, the new ditch lining solution passed several heavy water flow events. The City of Fort Worth will continue monitoring this project over the next year. If it continues to perform well, then their stormwater department hopes to implement Concrete Canvas as a standard solution for future repair and maintenance projects throughout the city.
Client Testimonial
“I am really happy with this and can’t believe it stood up to almost 9 inches of rainfall.”

In order to revitalize and meet stormwater codes, the abandoned parking area at the Shoppes at Fashion Square in Orlando, FL, required updates. With a permeable paving system and machine technology, we helped the client achieve their goals, save $1 million, and complete the project in just 10 days.
With solar panels in place and operational, an immediate and effective erosion control solution was imperative. Especially considering the panels were positioned next to channels, drip lines, and spillways.
After failed attempts to stabilize the earth at the Mt. Jackson Solar Farm, they required an immediate, cost-effective erosion control solution. Ferguson Waterworks was brought on board to address their ongoing concerns.
