Box Culvert Embankment Reinforcement/Retention System

Industry

Construction

Challenge:

The primary challenge was reconstructing the 3:1 soil slope adjacent to the box culvert to resist erosion and flooding without relying on costly and time-consuming cast-in-place concrete methods.

Achievement:

Titan successfully delivered a cost-effective and durable embankment reinforcement solution significantly improving the structural integrity of a flood-prone box culvert in Western Manitoba.

Product Used:

Titan Earth Grid®, Pyramid Grid®

Location:  Cartwright, Manitoba 

Project Type: Product Supply & Installation

Product Used: Pyramid Grid™

Challenge

Flooding, seasonal or other, takes a toll on local infrastructure and the environment. In Western Manitoba common valley flooding has, over time, weakened embankments adjacent to many concrete box culverts in the region. This had compromised the structural integrity and performance of a large concrete box culvert in the Rural Municipality of Cartwright

The challenge with this project was to reconstruct the 3:1 soil slope strata along the sides of the box culvert to withstand the elements and slow down or stop potential scour of the culvert surface.


Titan Solution

Titan designed a more cost-effective engineered earth system to mechanically stabilize the earth. This system included Pyramid Grid™, Use of Titan Earth Grid™, and TE-C32 coconut erosion control blanket with twisted wire gabion baskets.

The base was reinforced with Use of Titan Earth Grid™. Once that was completed the side slop embankment was constructed in compacted soil lift layers incorporating Pyramid Grid™ high tenacity uniaxial geogrid. This geogrid has high cross directional tensile strength and exhibits low creep. It also has high PH to take into consideration sub-standard compacted soil strata ensuring long-term performance of the structure.

The surface treatment was done with TE-C32 coconut erosion control blanket which worked as a system once vegetation germinated. We also supplied gabion baskets, TE-6 non-woven geotextile and silt fence.

Pyramid Grid™ is a high-strength uniaxial polyester geogrid engineered for soil reinforcement, offering exceptional tensile capacity, durability, and stability in demanding construction environments.

Achievement

Titan successfully implemented a cost-effective and environmentally resilient embankment reinforcement system. This enhanced slope stability, reducing erosion, and minimizing long-term maintenance costs for flood-prone infrastructure.
