Solution for damaged curb boxes
Argonics’ Speedy Sleeve polyurethane sleeve is specifically designed to repair damaged curb boxes. Engineered for ease of installation, access and maintenance, the sleeves are 6 to 18 inches in length with two small fins. The top opening is sealed with a screw-on cap. To install, cut off the top of the old pipe and then slip on the sleeve. To get a snug fit at an appropriate level - above or below ground - dig out around the pipe and then tap down with a hammer. The fins stabilize the device in the soil so that it won’t twist or move due to frost heaving.
