How it works

From request to report in four steps

A clear, repeatable process that keeps your project moving and your asset records defensible.

01

Request an Inspection

Send us an email or give us a call. We can match the right crew and equipment tailored to each job.

02

On Site CCTV Inspection

Crawler or push rod cameras capture high resolution footage and capture condition and defects.

03

Coding

Defects are coded and graded to the 4th edition gravity pipe inspection manual.

04

Reporting

You receive a clear, detailed report outlining any defects to support maintenance and planning decisions.

Grounded & responsible

Doing the right thing, on every site

Our values stem from family ownership — "because it's the right thing to do." We recover sands, aggregates and water for reuse, choose non-destructive digging methods that protect live services, and leave sites safer than we found them.

Safety – first

Health and safety is at the core of everything we do. This commitment allows us to provide safer operations and higher-quality outcomes.

Sustainable

Recovering sands, aggregates and water for reuse — improving your project's sustainability performance.

Flexible & Responsive

Known for our can-do approach, we work collaboratively with clients to adapt to changing requirements and deliver the support needed to keep projects moving.

Community & Environment

Committed to doing things the right way, we consider the impact of our work on the environment, our clients, and the communities where we operate.
