Driveway Extensions & Widening in Westland, MI
Driveway Extensions
Room for one more car, without the patchwork look.
Most Metro Detroit homes were built with a single-car driveway, and most families now have two or three cars. We widen and extend driveways so the new section sits level with the old, drains the same direction, and looks like it was always there.

Key considerations
What goes into it

- 05HOA width rules where they apply
Because Michigan weather is hard on concrete, we put the most care into the parts you can’t see: proper sub-base, reinforcement, and curing that make your concrete last.
What’s under the surface
A Michigan driveway, in cross-section
Not to scale · slope exaggerated
1Wet clay freezes and heaves in winter, then softens and settles in spring, moving whatever sits on top of it.
2Soft clay comes out and compacted 21AA aggregate goes in, so the slab sits on something that stays put.
3Rebar on chairs at mid-depth keeps any cracks that do form tight and level.
4An air-entrained mix survives freeze-thaw, and control joints decide where the slab cracks.
5The slab slopes away from the house, with an isolation joint where it meets the foundation.

Finish options
Straightforward or decorative
Broom finish
Fine ridges for traction on snow and ice. The standard for driveways.
Stamped
Patterned and colored to look like stone, slate or brick.
Exposed aggregate
The surface washed back to show the stone. Grippy and hides wear well.
Integral color
Color mixed through the whole slab, so chips don’t show grey.
Decorative borders
A contrasting band that frames a driveway or patio.
Sealed
Sealer before the first winter to resist water and road salt.
Where you live changes the job
A driveway extension on lake-plain clay is a different job than one on sandy outwash
Metro Detroit sits on three kinds of ground, and each one changes how we prepare the base, reinforce the slab and handle water. Your community page has the specifics.
Lake-plain clay
Dig out the soft clay, replace it with compacted 21AA aggregate base, and set the slope so water runs off the slab and away from the house.
Rolling glacial till
Proof-roll the subgrade to find soft spots, replace them, build a thicker compacted base, and plan the grade so runoff is carried around the slab.
Sandy outwash
Compaction done in lifts, a full-depth aggregate base, and a thicker section anywhere a truck, trailer or RV will park.
Questions and answers
Driveway Extensions: what people ask us
About the same per square foot as a new driveway, $12–$15 per square foot, so a 10 by 20 foot widening for one more car is typically $2,400–$3,000. Small add-ons cost more per foot because the crew and the truck cost the same, and an RV or trailer pad poured six inches thick runs $13–$17 per square foot. Widening the approach at the street adds a right-of-way permit.
The finish, the height and the slope will: the new section is set level with the old, drains the same way and gets the same texture. The color won’t match exactly at first, because new concrete starts out different and the old slab has years of weather and wear on it. If that matters to you, a contrasting border along the joint makes the difference look intentional.
Steel dowels are drilled into the edge of the existing slab and cast into the new one, so the two sections move together and stay level. The new part gets the same excavation and compacted base as a new driveway, because a widening poured on soft soil settles away from the old edge.
It depends on the city and the road. Canton Township caps a driveway on a Wayne County road at 26 feet wide at the sidewalk and limits paving to half the front yard, the Road Commission for Oakland County allows 10 to 25 feet at the property line on a county road, and Livonia needs prior approval for a curb cut over 25 feet. HOAs often set their own limits, so we check before we lay it out.
Long enough for the RV or trailer plus room to walk around it, and wide enough to open doors and set up; 12 by 40 feet fits many rigs. Pour it six inches thick on a compacted base, since a loaded trailer puts a lot of weight on a few small tires, and check your city’s rules on where an RV can be parked before you build.
Yes. We lay out the extra width, dig and base it like a full driveway and tie it into the existing slab. Chris will check the layout against your city's width and setback rules.
A turnaround pad off the side of the driveway works well on many lots. It needs enough room for the car to swing in and pull forward. We'll mark it out at the estimate so you can picture it.
A strip a few feet wide along one side often solves it and gives you room to open doors. It's built on the same kind of base as the rest of the drive. Small extensions like this are a common request.
The base does the work. We dig to firm soil, compact 21AA in lifts and reinforce the slab for the load. A thicker pad may make sense for a heavy trailer.
We plan the slope of the new section so it drains along with the existing driveway and away from the house. Sometimes that means pitching it toward the lawn on the far side. We'll show you the fall before we pour.
Typical prices for every kind of project are in the Metro Detroit concrete cost guide, and general questions are on the FAQ page.
