Drain pipe installation: trenchless vs. excavation


Drainpipe installation happens to be an integral component of building or even renovating buildings. Typically there are usually two kinds of methods that contractors utilize in such operations, and this article is geared to make a short review of them.

To begin with, there is the age old technique of excavation which entails the digging of trenches to lay drain pipes that shoot off building into a either a septic tank or municipality sewer lines. After the installation has been done these trenches are then refilled with earth. On the other hand, there is the relatively new trenchless method that is characterized by very minimal digging up of the ground to lay the drainpipes in either new installation or even replacement of old piping.


As would be expected the first alternative normally presents quite a number of challenges; and some of the most notable include:

  • The excavation process of installing drain pipes can wreck a lot of havoc to a property, especially on landscaping, walkways, driveways and so on.
  • There is a possibility of damaging underground utilities that the owner of the property may not be aware exist.
  • This technique usually gives rise to other unnecessary expenses in effectual site restoration.


  • Trenchless technology on its part necessitates, especially for pipe replacement, only minimum digging at the start and end points, and everything in between is left untouched. Which undoubtedly causes lesser damage than the former alternative.
  • Drain pipe installation contractors utilize soft, high-density materials such as polyethylene that aren’t prone to corrode, break, burst or get intruded by tree roots. This is stark contrast to the materials that are usually used for the excavation method. Which for the most part are concrete, cement or clay that are all susceptible to the above-mentioned challenges.

All in all, the trenchless technique is by far a much better solution as it leads to lesser damage to properties and is also less prone to necessitating constant repairs. However, one vital thing to take note of when opting for this drain installation method is that it requires a lot of expertise as well as experience to be able to execute it properly. Hence it is highly recommended not to try to conduct it on your own using DIY methods, but rather enlist the services of a skilled and experienced contractor.
