An 84" culvert pipe was rusting extensively along the bottom 1 foot invert of the pipe, the rest of culvert still in great condition. Typically this would be a remove and replace but county looking for ways to extend maintenance dollars. They filled in with grout all holes to provide a smooth flow line. The second step was to unroll concrete canvas and anchored to good portions of the pipe for a new flow line and extended culvert life. Entire process took roughly 2 days from start/finish.
Concrete Canvas® - It is a flexible, concrete filled geotextile that hardens on hydration to form a thin, durable and water proof concrete layer. Essentially, it’s Concrete on a Roll (TM).

Concrete Canvas® is part of a revolutionary new class of construction
materials called Geosynthetic Cementitious Composite Mats (GCCMs).
Common applications include:
• Channel Lining - Rapidly unrolled to form a ditch or channel lining. It is significantly faster, easier and less expensive to install than conventional concrete channel lining and requires no special equipment.
• Slope Protection - Protect slopes from surface erosion. Compared to shotcrete it is faster to install, more cost effective, requires less equipment, and eliminates risks associated with rebound and debris.
• Berm Lining - Cost-effective alternative for lining secondary containment berms. It acts as an effective weed suppressant, reducing maintenance costs as well as providing additional levels of impermeability.
• Remediation - Used to rapidly re-line and refurbish existing infrastructure suffering from environmental degradation and cracking
• Culvert Lining - Extend the durability of new culverts and upgrade existing structures, preventing the need for asset replacement.
• Weed Suppression - Effective, durable and long-term weed suppression, reducing devegetation requirements and associated maintenance costs.
