Superior Excavating Services

Near the Meramec, low spots can hold water while the hills above are rocky. We look at both before laying out a house pad or driveway, so the finished site works with the land instead of against it.

Reliable Septic System Services

Most Robertsville homes rely on private septic. We install new systems and replace failing ones, working through the Franklin County permit and soil testing that come first.

Excavation and Septic Work in Robertsville, MO

Robertsville is an unincorporated community in eastern Franklin County near the Meramec River, home to Robertsville State Park. Properties here tend to be rural and wooded, and many rely on private septic systems and wells.

Ground conditions around Robertsville

Land near the Meramec ranges from river bottoms that can flood and hold water to wooded, rocky hillsides above them. Low ground near the river needs extra care with drainage and septic placement, while upland lots often have cherty clay and shallow rock. We look at where a home, driveway or drain field can actually go before recommending a plan.

Permits and planning in Franklin County

Since Robertsville is unincorporated, Franklin County handles permits. New and replacement septic systems need a county sewer permit, which typically begins with soil or percolation testing. Properties close to the river may have additional floodplain considerations, which we help customers check before work starts. We request Missouri 811 utility marking ahead of every Robertsville excavation.

Robertsville, MO Excavation FAQs

Do you install septic systems for rural homes in Robertsville?

Yes. We install and replace septic systems and handle the excavation for drain fields, after the required Franklin County permit and soil testing.

Is building near the Meramec River different?

Low ground near the river can flood or hold water, which affects where a house, driveway or drain field should go. We factor that into the site plan.

Can you clear a wooded lot in Robertsville?

Yes. We clear trees and brush, grade the site and prepare a pad for building.

Do you repair broken water lines?

Yes. We dig up and repair leaking or broken water lines and restore the ground afterward.
