"A simple drain pipe replacement under a bathroom floor turned into a replacement of three lengths of drain pipe. In addition, when the finish up work in the basement was done, the waste lines going into that pipe were reconfigured so the washing machine and utility sink now drain directly into the pipe. Which let us take out the sump pump. Then, the plan to fit a pvc shield around the sewer pipe to the town sewer turned into a major excavation of a trench through an eight foot bed of shale because the incoming water line is 1/4 inch from the outgoing sewer line. And had a hole in it so it had to be replaced after all. The crew did a great job, they were pleasant throughout and I would recommend them to anyone."

FAQs for excavation projects in Mahwah, NJ

Depth depends on the type of installation and the regulations in your area. Water supply lines typically require 24 inches, while drainage pipes are often installed 36 inches below grade. For most general projects, a depth of 12 to 24 inches and a width of about eight inches is sufficient. Sticking to these specs keeps your utilities safe, code-compliant, and easier to maintain later.

When you need to run utilities underground, you’ve got two main options: boring or trenching. Boring employs directional drilling to install utilities without exposing a continuous channel, while trenching requires excavating an open channel to place utilities securely. Directional drilling preserves landscape integrity, whereas trenching provides direct access for installation, albeit with greater surface disruption. This clear comparison helps you select the method best suited to your project.

Plan on 12 hours to dig 100 linear feet when the soil is cooperative and you can work continuously. This timeframe applies when work is performed consistently and methodically. Factors such as rocky soil, tree roots, obstructions, and frozen ground increase the overall duration, demanding extra planning and effort. Comprehensive operational planning ensures that every challenge is managed efficiently and the project is completed on schedule.

If you want your yard to look untouched, laying fresh sod over the trench is the quickest fix. New sod needs 30 to 45 days to root and blend with the rest of your lawn. A local sod pro can provide you with a firm timeline and tips to ensure the grass takes hold and maintains your curb appeal.
