Challenge:
This project required rapid, repeated predesign revisions to keep pace with shifting site conditions and evolving engineering recommendations.
Achievement:
Titan’s Gladiator Grid® solution significantly reduced subbase and base material requirements across paved and unpaved areas. Therefore delivering measurable cost, time, and environmental savings for the client.
Product Used:
Gladiator Grid®
Location: Springfield, MB
Project Type: Pre-Design and Product Supply
Product Used: Gladiator Grid® 550 and Gladiator Grid® 550C
Challenge
The project demanded an unusually high level of adaptability, as Titan had to navigate multiple rounds of predesign revisions driven by shifting site conditions and evolving engineering recommendations—all under a tight timeline.
The engineering team was working with a very plastic clay subgrade, heavy ESAL loading requirements, and the need to accommodate 90,000‑lb semi‑trailers, which added complexity to the design process. Balancing these technical constraints with the client’s goal of reducing subbase and base thicknesses across both paved and unpaved areas required Titan to continuously refine design assumptions, update calculations, and respond quickly as new information emerged. Despite these pressures, Titan maintained alignment with the engineer and contractor, ensuring the design remained structurally sound, economical, and feasible for construction.
Titan Solution 
Titan proposed a targeted reinforcement strategy using Gladiator Grid® 550C and Gladiator Grid® 550 to stabilize the challenging subgrade and reduce aggregate requirements without compromising performance. For the light‑ and heavy‑duty asphalt areas, Titan recommended installing Gladiator Grid® 550C directly atop the subgrade to provide separation, confinement, and improved load distribution. This allowed for meaningful reductions in both subbase and base thicknesses.
In the heavy‑duty unpaved gravel areas, Titan designed a dual‑layer system with Gladiator Grid® 550C at the subgrade and Gladiator Grid® 550 at the subbase, further enhancing stability and enabling additional material savings. This approach outperformed the initial conventional recommendations by offering a more economical, environmentally responsible, and construction‑efficient solution. With approximately 10,665 m² of Gladiator Grid® 550C and 3,555 m² of Gladiator Grid® 550 installed, the system was engineered to withstand high ESAL values and frequent heavy truck traffic while addressing the challenges posed by the very plastic clay subgrade.
Gladiator Grid® is a high-performance geogrid possessing high radial stiffness at low strains and engineered for soil reinforcement and stabilization in challenging site conditions.
Achievement 
By implementing Gladiator Grid®, the project achieved measurable reductions in aggregate use across all pavement and gravel zones, directly lowering material costs, construction time, and environmental impact. Heavy‑duty asphalt areas saw a 50 mm reduction in both subbase and base layers, while light‑duty asphalt areas achieved a 20 mm subbase reduction and a 50 mm base reduction—representing savings of 10–25% depending on the layer.
The heavy‑duty gravel areas also benefited from significant, though unquantified, reductions in subbase and base materials. These efficiencies not only reduced the project’s carbon footprint but also supported long‑term performance on a site expected to regularly accommodate 90,000‑lb semi‑trailers. Stakeholders reported that installation proceeded smoothly, and the final design delivered the durability, cost savings, and sustainability benefits the client sought.
