Pipe Repair Matrix - Hugger Bands

Repair Couplings and Bands External repairs for larger damaged areas in PVC pipes are typically performed by cutting out the entire damaged section of pipe and splicing in a new pipe section. In doing this, the damaged section must be cut out squarely and a near identical length of new pipe put in its place.
To properly make an external repair, the bedding beneath the pipe at the points the damaged pipe will be cut, needs to be removed for a distance of a foot or so on each side of the cut. This aids cutting the damaged section out, and also leaves working room to install a suitable joint between the old and new pipe sections. Once the entire repair to the pipe is made, this bedding material needs to be replaced and compacted to assure line and grade control.
Because the FL DOT requires watertight joints, any of the following repair couplings or bands involves using gaskets from the pipe supplier placed and lubricated (per the manufacturers instructions) in the first and second corrugation valleys on both sides of each pipe cut prior to the final positioning of the coupling or band.
The pipe manufacturers and supporting industry offer several types of repair couplings including:
Sleeve couplings that can be worked over the connection by sliding them completely onto the repair section before it is placed and then slid back and centered over the joint after placement.
Rubber or flexible thermoplastic couplings (or boots) are offered by Fernco and others. These can be placed on the ends of the repair section, rolled back during placement and then rolled over the joint after the repair pipe is placed. They are tightened in place with the stainless steel bands and included hardware at each end of the coupling.
Flat or partially corrugated (Hugger type) bands are available from corrugated metal pipe suppliers. These are centered under the cut pipe ends and tightened after the repair section is placed. They are used with an additional 12-inch wide flat gasket. Metal bands shall be made of Aluminized type 2 steel or aluminum, meeting any alternative metal pipe option on the project.
