Meet the Equipment | HAMM H 10i Vibratory Compactor

You can't build on soft ground — and that's exactly where this machine steps in.

Our HAMM H 10i is a single-drum vibratory soil compactor, and it plays a critical role on every project we touch. After our dozers spread a lift of fill material, this machine rolls over it with massive vibratory force, compacting soil to the density required by the geotechnical engineer.

Why does compaction matter?
Prevents settling and structural failure of buildings, roads, and parking lots
Required by geotechnical engineers — tested and inspected on every project
Ensures underground utility pipes are surrounded by stable, dense backfill
Without proper compaction: roads crack, slabs settle, pipes shift — not on our watch

Its articulated frame handles tight turns, and its vibratory drum delivers the force to meet compaction specs lift by lift. We build from the ground up, the right way. 🏗

From 500 feet up, the chaos makes sense.

What looks like a dirt maze from the sky is actually a full-scale underground utilities installation in progress. Here's what you're looking at:

Multiple excavators working simultaneously, cutting deep trenches for underground utility lines Green conduit & pipe staged and ready for installation — those utilities have to go somewhere! Crushed stone bedding is being placed in the trench — because proper pipe bedding isn't optional, it's the difference between a 50-year system and a 5-year headache Heavy equipment grading and moving earth across the entire site — every track mark tells a story

This is what it looks like when a site goes from raw dirt to ready for the future. Underground utilities aren't glamorous... until you see the scale from a drone.
We move dirt. We lay pipe. We build the infrastructure that everything else depends on.

Meet the Equipment | Komatsu D51EXi Dozer

Smaller footprint. Same smart technology. All the hustle.

Our Komatsu D51EXi is the mid-size dozer in our fleet, and like its bigger brother the D71, it runs Intelligent Machine Control with GPS grade guidance. This machine shines when we need precision in tighter areas or on smaller developments.

We put this machine to work on:
Residential lot grading and site preparation
Fine grading of subgrade before aggregate placement
Sloping and shaping roadside ditches and drainage swales
Jobs where a larger dozer would simply be too much machine

Don't let the size fool you — the D51EXi is a production machine that delivers real results. GPS guidance means fewer re-work passes and more accuracy on every cut.

Our Volvo SD-105DX soil compactor is one of the most important machines on any site.

That large padfoot drum up front uses thousands of pounds of force and vibration to compress soil, clay, and fill material into a dense, stable base. Without proper compaction, buildings settle, pavements crack, and utilities fail. This machine makes sure that doesn't happen.

Before any slab pours or road base goes down, our Volvo is rolling over every lift, pass by pass, making the ground rock solid. It's not glamorous — it's essential.

Our Doosan DA30 articulated dump truck is the backbone of earthmoving on the job. With a 30-ton payload capacity and six massive tires, this beast hauls dirt, rock, and fill material across rough terrain that would stop a standard truck in its tracks.

The articulated frame means it bends in the middle, giving it incredible maneuverability on tight, uneven ground. Whether we're cutting and filling a new pad, clearing a site, or managing stormwater grading, the DA30 keeps material moving fast and keeps the schedule on track.

Bigger loads. Fewer passes. More progress. That's how we work.
