Which PipePatch fits the job?
Pick what the camera shows to see the right kit. And when point repair isn’t the answer, we’ll tell you.
Good fit
Crack or fracture
This is what PipePatch is for. Clean the pipe and center the repair on the crack. It cures into a new fiberglass wall that spans the damage.
Good fit
Hole or missing piece
PipePatch can bridge a hole or a missing piece of wall, as long as the pipe still holds its shape around it. Center the repair on the damage.
Good fit
Open or separated joint
A repair centered on the joint seals it.
Good fit, after cutting
Roots
Cut the roots back to the pipe wall and clean the line first. Then repair the joint or crack they came in through. PipePatch seals the opening; it doesn’t remove roots for you.
Good fit
Infiltration
The resin cures in the presence of water, so groundwater coming in doesn’t stop the repair. Patch the joint or crack where it’s getting in.
Check it first
Offset joint
A small offset can be bridged: Long Beach Utilities used two patches to transition an offset and cover a broken section. The packer has to pass the offset and seat the patch on both sides, so check it with a dry run. A severe offset may need a dig.
Use the right kit
Leaking lateral connection
Where a lateral joins the mainline, use TYGERPatch. It seals the tee or wye from inside the mainline, reaching 6″ to 10″ up a 4″ to 6″ lateral, with no digging and no access to the property needed.
Use the right kit
Damage at a bend
Use a PipePatch Elbow kit with an elbow packer, made for repairs at a bend. If the damage is past a bend, there are packers built to get through elbows on the way.
Use the right kit
Damage over a long stretch
PipePatch XTEND kits cover up to 15 feet in one patch in 3″ to 6″ pipe, and longer damage can take more than one repair placed end to end. If the whole run is bad, a full-length liner may cost less than many point repairs.
Not a fit
Sag or belly
A point repair can’t change the grade. Water and solids will still collect in the low spot. Fixing a sag means re-laying the pipe.
Not a fit
Collapsed pipe
The packer needs a pipe that still holds its shape to press the patch against. A collapsed or crushed section needs to be dug and replaced.
One system, 1-1/2″ to 72″
From a small drain to a large culvert, plus lateral connections. The same kit approach, sized to the job.

Add No-Dig repair to the jobs you quote. Show the customer the camera footage before and after. That’s how the job sells.
How a PipePatch repair goes
Eight steps, with the camera at the start and the end.
Step 1 of 8
Inspect
Camera the damaged area and confirm the pipe is structurally sound enough for a point repair.
Step 2 of 8
Clean
Remove all roots, debris and sharp edges, then camera it again. Sharp edges can puncture the packer.
Step 3 of 8
Measure and transfer
Center the camera head on the damage and tape-mark the cable. Transfer that mark to your push rods.
Step 4 of 8
Test and dry run
Inflate the packer in a same-size pipe and add 2 psi to the gauge reading. That’s your pack pressure. Then do a dry run to your mark, without inflating.
Step 5 of 8
Wet out the mat
Mix all the resin and record the start time. Saturate both sides of the mat, then fold it with a 1″ overlap.
Step 6 of 8
Roll onto the packer
Fit a new protective sleeve. Roll the patch tight around the packer, secure it with ties and trim the tails.
Step 7 of 8
Place and inflate
Push to your mark and inflate to your pack pressure. Never exceed the pressure stated on the packer.
Step 8 of 8
Cure and inspect
Hold pressure for the time on the cure chart. Deflate, pull it out with the pull cable, not the push rods, and camera the repair.
These steps are an overview. Always follow the instructions in your kit.

Job log and cure planner
Time, temperature and pressure
On the job, log the pressure from your test run and your times, then email or text the record to yourself. Before the job, plan the cure with the PipePatch cure charts.
°F °C
Check the air in the pipe with a temperature gun if you can. In winter it’s usually warmer than the air above ground.
Cold-weather job
- Keep the resin warm until you mix it: in the heated cab, not the truck bed. It is recommended to mix near 70°F.
- Go by the air in the pipe. It’s usually above 30°F even when it’s colder on the surface.
- Use winter or rapid resin, and plan on more working and cure time.
- Colder than the chart? Hold pressure past the coldest row’s cure time before you deflate.
Hot-weather job
- Wet out in the shade, out of direct sun.
- Keep kits cool until you use them. It is recommended to store the resin in a cool place.
- Use summer resin for the most working time, and stage everything before you pull the clip.
- Hotter than the chart? Working time is shorter than shown. Move fast.
Summer

- Cure time
Winter

Times are from the PipePatch winter, summer and rapid resin cure charts, by ambient temperature, and start when the resin is mixed. Between chart rows, the planner takes working time from the warmer row and cure time from the colder row. Outside the chart, it shows the nearest row as a limit. Always follow the instructions and safety data sheet in the kit, and confirm the repair with your camera before you put the line back in service.
FAQ
Common questions
What is PipePatch?
PipePatch is a No-Dig, trenchless cured-in-place (CIPP) point repair system. It repairs a damaged section of pipe from the inside: a resin-saturated fiberglass mat cures in place into a structural repair within the host pipe.
What types of damage can PipePatch repair?
Localized damage in pipe that’s otherwise sound: cracks, holes, joint separation, root intrusion, corrosion and infiltration. It isn’t the fix for sags, collapsed pipe or badly out-of-round pipe. Check your damage.
Is PipePatch a permanent repair?
It’s a structural repair, not a temporary patch, and it’s backed by a 50-year guarantee: if a repair fails, the kit is replaced, as long as the installer was factory trained, used genuine PipePatch tools and components, followed the kit instructions, kept records of the job, and sends in a written report. There’s also a 1-year limited warranty against defects. Ask us for the full warranty terms.
Can PipePatch be installed indoors?
Yes. The resin contains no VOCs or styrene and is non-flammable, so there’s no styrene odor in the building. It’s still a chemical product: wear the gloves in the kit and read the safety data sheet before you start.
What pipe sizes can PipePatch repair?
1-1/2″ through 72″ across the kit line, depending on the repair system. The ICC-ES listing covers 2″ to 72″, and NSF evaluated 3″ to 60″. See the kit lineup for each kit’s range.
Can PipePatch be used with full-length lining?
Yes. Point repair and full-length lining can be used on the same line; ask us about sequencing. When the camera shows damage along the whole run, a full-length liner is usually the better buy. Sags, collapsed pipe and bad grade need a dig either way.
Can I repair a pipe with water in it?
Yes. The resin cures in the presence of water, so infiltration and standing water don’t stop the repair. Flow-through packer options let the line keep flowing during the cure. Clean the pipe first: debris under the patch keeps it from bonding to the wall.
Do I need to be certified?
Yes. PipePatch’s ICC-ES listing requires installers who are factory trained and certified on site, and the 50-year guarantee requires factory training. Buyers of the system are certified for free. Get certified.
What’s in the box?
Each Standard kit has pre-measured resin, a pre-cut fiberglass mat, a ground sheet, a resin spreader, gloves, two packer sleeves (one for the dry run, one for the repair), wire or cable ties and tape.
What equipment do I need?
A packer and regulator assembly for the pipe size, push rods, a flex adapter, pull cable, a sewer cleaner, a sewer camera, an air compressor and air hose, a tape measure, wire cutters and safety glasses. A temperature gun is recommended. You also need a short piece of pipe the same size as the repair, to test the packer. PipePatch ONE puts a disposable packer and push hose in the box with the fiberglass and resin. PipePatch offers packers sized to the pipe and the repair length, with options for bends, long repairs, large pipe and lines that need to keep flowing during the cure. Most are reusable from repair to repair. Not sure which fits your work? Ask us.
PipePatch offers packers sized to the pipe and the repair length, with options for bends, long repairs, large pipe and lines that need to keep flowing during the cure. Most are reusable from repair to repair. Not sure which fits your work? Ask us.
Will roots grow back through it?
The repair seals the joint or crack the roots came in through. Cut the roots back to the pipe wall and clean the line first. There’s no published root-resistance test, so we don’t make a claim beyond that.
How long does a repair take?
Most of it is the cure. At about 68°F, rapid resin cures in 25 to 30 minutes and winter resin in 75 to 100. Add the camera work, cleaning, a dry run and wet-out. Long Beach Utilities had its lateral repaired in under half a day.
What about longer damage?
For damage that runs for feet in 3″ to 6″ pipe, PipePatch XTEND repairs up to 15 feet at once. Longer runs can take more than one repair placed end to end; ask us how. If the whole line is bad, a full-length liner may be the better buy.
Does it work in cast iron, clay, concrete and plastic?
Yes. NSF evaluated PipePatch in cast iron, clay, concrete and plastic pipe.
