Top Gun Manhole to Manhole Lining SystemWe’ve been touting the benefits of trenchless technologies for a long while now. It is a good portion of our business, so we naturally think very highly of it. A quick search on Google shows that other people do too. However, it’s not widely discussed when it wouldn’t make sense—which there are cases out there when it doesn’t. Oftentimes, the benefits are huge and solve a ton of problems. The trenchless part keeps your lawn pretty and the hassle down.

However, those moments when trenchless technology don’t make sense are few, but they’re there. For instance, what if you’ve got a pipe only a few feet below the ground that needs replaced, and that pipe is located out of the way where the trenches wouldn’t get in anyone’s way. These invalidate most of the reasons to use trenchless technologies. Thanks to the minimal excavation and the lack of need for the resin–fiberglass liner, the costs are way down, below the cost of trenchless methods. This is a major case for excavation.

The Cost Difference

Costs can definitely get in the way of trenchless technology. While there is far less digging and labor involved with the process (which is a major advantage), the costs can come closer to excavation than you might be comfortable with. In fact, if the pipe is close to the surface, excavation costs might be so minimal that it becomes the cheaper option. Don’t forget the little details—it might sway your decision in either direction.

The Materials

Also, there is the matter of the pipe. We’d like to think that the ground beneath our feet is solid, but it’s not. Soil and sand shift as things compact and compress, and little movements over a great period of time might allow a pipe to sag and eventually bend. If the problems that you’re having are related to bending pipes or other deformities in the pipe, then lining won’t be your solution—which is a major part of trenchless technology. There’s also the problem of major deformities. For instance, the pipe bursting method won’t work if a portion of the pipe is collapsed—the bursting head won’t be able to make it through the pipe if this happens. Likewise, if the soil surrounding the pipe isn’t solid or there are other pipes around the one you’re replacing, you won’t be able to burst it. And push-in-place pipe replacement won’t work if the pipe is deformed or bent, either.

The Methods Depend On The Situation

Just like everything else in this world, everything is situationally dependent. You might have the perfect (or close to perfect) situation for your pipe to be lined or replaced through trenchless methods, or at the least have it be the cheaper, better option for your situation. Likewise, you might have other issues that make it easier, cheaper, and better for you to excavate the pipes rather than just relining. Be sure to pick the best option for you, and you won’t have to worry.
