M&M Concrete Inc. · Licensed C-8 #1141877 · Inland Empire
Excavation and trenching with our own machines
Footings, pads, pool digs and utility trenches, dug to the string line and hauled off in our own trucks.
M&M Concrete excavates for concrete, construction and landscape projects across the Inland Empire. The same crew that digs the footings is the crew that forms and pours them, so the trench is the right depth the first time and nothing waits on a second company.
We run a Cat 304 and a Kubota U17 mini excavator alongside our track loaders, which covers everything from a footing trench in a 3-foot side yard to a building pad on a commercial lot. Dirt leaves on our own Ram 4500 trucks and dump trailers.
What we handle
- Footing and foundation excavation
- Building pads and over-excavation
- Pool and spa digs
- Trenching for water, sewer, electrical and drainage
- Cut to grade and dirt haul-off
- Site clearing and rough grading
- DigAlert 811 utility locating before we dig
Footings, pads and foundation digs
Continuous footings, pad footings and over-excavation for slabs and ADUs are our everyday work. We dig to the engineer's depth, keep the bottom clean and compact the subgrade so the inspector signs off the first time.
Because we also pour, we know what the concrete crew needs: square corners, the right width for the forms and rebar clearance, and spoils stacked where they will not be in the way of the pump truck.
Trenching for utilities and drainage
We trench for water, sewer, gas sleeves, electrical conduit and storm drain, and we backfill and compact in lifts so the surface above does not settle. On commercial jobs we cut and patch back asphalt or concrete so the finished trench disappears.
We call DigAlert (811) before every dig and hand-dig around marked lines.
Tight access is normal for us
A standard 3 ft 6 in or 4 ft side gate is wide enough for our SCL1000 mini track loader, and the U17 excavator is sized for the same tight spaces. Backyard pools, side-yard trenches and ADU pads behind an existing house are the jobs we are set up for.
Excavating jobs we have done
Questions we get asked
Are you licensed and insured?
Yes. M&M Concrete Inc. holds a California C-8 concrete contractor license, CSLB #1141877, and is registered with the DIR (#2000016629) for prevailing-wage public work. We carry $1M per occurrence and $2M aggregate general liability plus a $2M umbrella, and we can add your project as additional insured before we start. You can check the license yourself on the CSLB website.
Do you call in utility locating before you dig?
Yes, every time. California law requires a DigAlert (811) ticket at least two working days before excavation, and we file it as part of scheduling the job. Public utilities get marked for free. For private lines on your side of the meter, like irrigation, a pool line or a run to a detached garage, we ask you what you know and hand-dig around anything marked.
What size machines do you run, and will they fit my property?
Mini excavators (Cat 304 and Kubota U17), mini track loaders (Kubota SCL1000 and Bobcat MT100), a skid steer (Kubota SSV65) and a full-size track loader (Bobcat T770). The SCL1000 fits through a standard 3 ft 6 in or 4 ft gate. Send us a photo of the narrowest point on the way in and we will tell you which machine it is before we quote.
Do you haul off the dirt, or does it stay on site?
Your choice. If you have a use for it we can stockpile or spread it. If not, it leaves in our own dump trailers and the haul is included in the price. Clean fill and broken concrete go to different places, so we keep them separate on site.
How deep can you dig, and do you shore the trench?
Our mini excavators dig to roughly 10 to 12 feet. Any trench five feet or deeper that a person enters gets shored or sloped per Cal/OSHA, and we plan that into the job rather than improvising on the day. Most footing and utility trenches are shallower than that.
Do I need a permit for excavation or grading?
Often yes, and it depends on how much dirt is moving and whether you are changing drainage. Most Inland Empire cities require a grading permit once you pass a set cubic-yard threshold, cut or fill past a certain depth, or change how water leaves the property. Small trenching for a footing or a utility line usually does not. We know where each city draws the line and will tell you upfront which side of it your job falls on.
