Excavation & site prep

Excavation, grading & site preparation

The part of the job nobody photographs and everything depends on. Removal, excavation to depth, subgrade correction, granular placement and compaction — for our own paving contracts and as a standalone service for builders.

Everything above the base is finish work

A paved surface is only as good as what is under it. Excavate too shallow, leave soft clay in the subgrade, place granular in one thick lift instead of two compacted ones, and the surface will fail on schedule no matter how good the asphalt was.

We excavate to the depth the use requires, correct soft spots rather than paving over them, place and compact granular in lifts, and shoot grades so water leaves the site the way it is supposed to.

We also do site prep as a standalone service for builders and landscape contractors — pad preparation, trenching, drainage, and rough and finish grading.

How the job runs, step by step

01

Survey & grades

Existing elevations shot, drainage paths identified, and design depths set for the intended use.

02

Removal

Existing surfaces broken out and hauled to a recycling facility wherever the material allows it.

03

Subgrade correction

Soft spots dug out and replaced rather than covered. We show you the subgrade before anything goes over it.

04

Granular in lifts

Granular B and A placed and compacted in lifts to the specified depth, with grades checked as we go.

05

Finish grade

Final grade shot and confirmed, drainage cuts formed, and the base photographed before it is covered.

What we get right

Where site prep goes wrong

Book a Site Visit

Excavating too shallow

Saves a few hours and costs the whole surface. Depth is set by the load, not by the schedule.

Paving over soft clay

Clay that pumps under a compactor will pump under traffic. It has to come out.

One thick granular lift

Compaction only reaches so deep. Lifts are what make a base behave like a base.

No grade plan

Drainage designed after paving is not drainage. Grade is decided before base goes down.

Reusing unsuitable material

Old crushed asphalt has a place; wet fill and organics do not go under a paved surface.

Covering the base unphotographed

Once it is paved, nobody can verify it. We document every base we build.

Excavation questions

Do you do excavation without paving?

Yes. We do site prep, pad preparation, trenching and grading as standalone work for builders, landscape contractors and homeowners running their own projects.

How do I know the base was built properly?

Ask for depths and compaction on the quote, and ask to see the base before it is covered. We photograph the prepared base on every job — if a contractor will not show you the base, you are buying on faith.

What happens to the material you remove?

Old asphalt and concrete go to a recycling facility rather than landfill wherever the material allows it. Tipping is charged by the tonne, which is why disposal volume shows up as its own line on your quote.
