How far can you video inspect?

Thuro has access to a wide variety of pipe inspection equipment including small push rods for residential services and electrical conduit lines to robotic video crawlers for inspecting sewer and storm mains. A quick rule is anything less than 500m in length is not a problem but things can get more complicated when there are several bends in the line. We definitely do not mind the tricky stuff.

Why can’t my regular plumber just fix this for me?

Many of the sewer and water problems that Thuro solve require very specific tools and equipment that most plumbers don’t have access to. In fact, many of the permanent fixes to sewer and water problems are completed by…

Thuro provides written quotes in simple, easy to understand English with set, fixed pricing.

Are trenchless sewer repairs permanent?

Yes, Thuro specifically designs our sewer repairs to be trouble free when installed. Once we are finished the work, there is no maintenance required.

How long does will it take to fix my sewer?

Repair times vary depending on how severe the problems are and what method is used to fix it. Simple drain issues can be repaired in minutes but most projects, such as liners or pipe bursts, will be started and finished in 1-2 days.

Is trenchless better than digging?

Trenchless is better than digging because it saves our clients’ money. Lining and Pipe Bursting solutions are completed quickly. They offer minimal disruption to your landscaping, time, and life. There are also other benefits when compared to excavation such as repairing and replacing underground lines running underneath large trees, garages, or concrete patios and decks. However, there are times where full excavation is needed like when a pipe is completely collapsed or crushed. Thuro Inc. offers all methods of repair and replacement. We will customize a solution based on your problems. We assess your pipe by video to see all the problems and find the best option for you. So, is trenchless better than digging? Call us for a video inspection today to find out if a trenchless solution is right for you!

There are two main methods of trenchless repair. Pipe Bursting and Pipe Lining, also known as CIPP (Cure In Place Pipe). Thuro offers both methods as well as full excavation so we know know the pros and cons of all three. Lining is a low cost option for pipe in overall good condition but with ongoing maintenance issues such as root blockages. Pipe Bursting can fix many more sever issues 80% collapses or severe displaced joints. Excavation can also be a low cost option if the damaged area of pipe is small. The best way to find out what method is best for you is a video inspection. Having a video inspection done is relatively low cost and can save you thousands of dollars by getting the right information to make an informed decision.

What is a pipe burst?

Pipe bursting is feeding a steel cable down your line along with a specially designed tool, attaching a brand new sewer pipe on the other side, and winching the special tool and pipe through the existing pipe. This destroys the existing pipe but leaves behind a completely smooth, jointless, new pipe. Both water lines and sewer lines can be repaired this way. 

How long do liners last for?

Manufacturers are expecting over 50 years for a liners life… and part of the reason is there hasn’t been enough time passed to actually see when these will start degrading. They will last for a very, very long time.

What is a liner?

A liner is a seamless pipe sleeve that is installed inside of an existing pipe. The sleeve is made of felt with a plastic coating on one side. The felt portion of the liner is saturated with an epoxy resin. The liner is then inverted into the existing pipe (if you can picture unrolling a pair of socks) so that the plastic coating is in the inside of the pipe and resin is on the outside against the existing pipe wall. A calibration tube is then inverted (like a long balloon) and inflated to hold the liner open against the existing pipe. Steam is used to cure the resin. The end product is a hardened pipe moulded to the inside of the existing pipe.

The liner is about 3.5mm thick so in total it reduces the inside size of the pipe by about 7mm. This reduction in size will not have a negative affect on the flow. As the new liner is smooth and seamless (no joints) it will instead increase the flow rate. A four inch service pipe is oversized for regular residential use so there will be no issues caused by the minor reduction to the inside diameter (Pipe ID).

Thuro is a Perma-Liner Certified installer and we have installed hundreds of liners in Calgary and Southern Alberta. A CIPP liner is a permanent repair. It will extend the life of the existing pipe by at least a full lifetime. Current third-party testing through ASTM shows a life expectancy of 50 + years, however this number grows each year. Lining was first invented in 1971, and Thuro was actually the first company in Calgary to utilize this trenchless technology. We have been installing liners for 25 years and none of our liners have failed following a successful installation.
