Laying the Groundwork for Lasting Results

Why does professional excavation matters?

Excavation is more than just moving dirt. It is the foundation of every successful construction project, and when done right, it prevents structural issues, drainage problems, and costly delays down the line.

Whether you are breaking ground on a new build, prepping for utilities, or managing a contaminated site, you need a team that works precisely and safely. We use modern equipment, trench safety systems, and proven processes to ensure every job is done right the first time.

1

Prevent costly delays

Accurate excavation eliminates rework and keeps your project on schedule.

2

Protect structural integrity

Proper grading and soil prep create a stable foundation that lasts.

3

Ensure safety & compliance

We follow OSHA trench safety standards and use the right equipment for every site.

A Process Built on Precision, Safety & Preparation

What to expect from an excavation project

Every excavation project comes with its own unique set of conditions: soil composition, site access, and structural goals all play a role. At Hellem Construction Group, we take a meticulous, step-by-step approach to ensure your site is prepared properly and safely for what comes next.

Our Standard Excavation Process:

Preparation & Utility Mark-Outs

We coordinate with Dig Safe (811) and assess subsurface conditions to identify and avoid buried utilities and potential hazards.

Staking & Layout

Using detailed plans and precise measurements, we mark out digging areas, depth targets, and grade elevations for accurate excavation.

Mobilization & Equipment Delivery

We deploy the right-sized equipment based on the job’s scope - mini-excavators, trench boxes, loaders, and compaction tools.

Excavation & Soil Testing

Our team begins excavation while testing and monitoring soil conditions to ensure structural stability and proper compaction throughout.

Cleanup & Site Readiness

After excavation, we perform final grading, import clean fill if needed, and prep the site for construction or utility installation.
