"Clean, professional, and personable. Not at all what I was expecting from a plumber. Customer for life. The best part of the experience was how informative George was at each step and how interactive the project was (I was more than happy to lend a hand/hand tools). His pricing is right in line with the value you receive!!! Thank you, Olympic!!"

"We got multiple bids for this job and besides being the most economical they did an incredible job in a very timely manner. I highly recommend them if you need to have an underground oil tank removed. I was always kept aware of the progress of our project and Roseanne who I dealt with could not have been more professional, straight forward, and courteous."

FAQs for excavation projects in Lake Hiawatha, 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.
