Before we get started, you must do the ground tracing process and lay down the center lines. Once it’s marked on the ground, you will stretch a string between wooden pegs. Ground tracing is where we lay down the excavation lines and center lines etc.; this is done before the excavation is started. For example, the centerline of the longest outer wall of the building is marked on the ground by stretching a string between 2 pegs. This setting out process gives us the proper guidelines for the project.

Some of the services that we offer:

Sitework

Marblehead Dredging & Marina Services offer industrial, commercial, and residential site development. Our experience with the site development and construction is ideal for businesses, homeowners, and land developers looking to build a new project.

Large Excavations

We have a wealth of knowledge on all types of soil conditions and procedures to perform largely
excavation projects throughout the Lake Erie Islands area.

​

Services Include:

• Site Clearing

• Lot Leveling

• Grading Contractor Services

• Backfill

• Basement Excavation

• Sewer & Water

• Foundation Work

• Erosion Control

​

Another important part of the construction process is backfilling. This begins right after the
excavation process when the soil is compressed back into the trench. This supports roadways,
foundations, walkways, and other structures related to using a mixture of soil.

​

The process of backfilling is putting the soil back into a foundation or trench once excavation has
been completed. The process of backfilling requires heavy equipment and skills, soil conditions,
and an understanding of the specifications.

​

When placing or compacting backfill, the crew must take care to prevent impact loading of any
pipeline, cabling, shaft, structure, or other buried components. There are a few techniques of
backfilling and compacting the soil. It takes special considerations for compacting and filling
trenches for utility lines.

​

To prevent safety issues, you need the proper sequence of backfilling and excavation. The essential parts of the construction process are the excavation and backfilling of soil, and responsibility must be taken from a safety perspective to ensure the job is done right.

​

During excavation, you may encounter different soil layers, and dewatering may sometimes be needed.
These skills must practice these methods to take fundamental action during backfilling and excavation. In addition, you must take the correct measurements because the excavation cost is a huge part of the foundation construction.

​

Backfilling Quality Check

• Record the ground level

• Make sure the sample is approved for backfilling

• If necessary to create reference points are settled for the final level of backfilling

• Backfilling is being carried out in layers to 15cm to 20cm

• Watering is required, compaction is now completed

• The density that is required is accomplished
