Culvert Pipe Replacement in Olney, MD
When the pipe under your driveway fails, the driveway follows. We handle both.
Olney Culvert Replacement and Driveway Repair, Permitted and Inspected
Olney sits at the northeastern edge of Montgomery County, where the county’s older residential neighborhoods give way to larger lots and more open land along Route 108. The drainage infrastructure underneath Olney driveways reflects the age of those neighborhoods — pipes that were put in the ground when the homes were built in the 1960s, 1970s, and 1980s, many of them now past the end of their service life. When those pipes fail, the driveway above them sinks or collapses, and no surface repair holds until the pipe underneath has been replaced.
Culvert pipe replacement in Montgomery County requires a permit, county inspector oversight throughout the job, and compliance with the county’s right-of-way standards. The repair isn’t just about the pipe — it’s about restoring the public right-of-way to county specifications before the inspector signs off. Most paving companies don’t do this work. We do it regularly.
Culvert Pipe Replacement for McIntyre on Mount Olney Lane
Olney Mill, Olney, MD
What We Found
The McIntyre property on Mount Olney Lane in Olney Mill had a failed culvert pipe under the driveway apron at the public right-of-way. The old pipe had given out — the area needed to be opened up, the failed pipe excavated and removed, and a new county-approved pipe installed before the driveway surface could be restored. The work fell within the Montgomery County right-of-way, which meant it required a permit, a DPS ROW Inspector on site, and full restoration of the right-of-way to Montgomery County standards upon completion.
What We Did
We saw-cut the asphalt in the affected area — a 5×13 section — and removed it. We excavated down to the failed pipe and hauled it away. We installed a new Montgomery County approved 13×17 squash pipe, 24 feet long, to county specification. We filled the area above the pipe with CR-6 stone and compacted with a 3- to 5-ton roller. We laid 4 inches of base asphalt — the county-required depth over a culvert pipe — and power rolled. We applied tack coating so the two layers would bond as one structure. We machine-laid 2 inches of topping asphalt and power rolled to a smooth finish. We restored the right-of-way to Montgomery County MC-301.03 driveway standards, in compliance with the Public Right-of-Way Accessibility Guidelines (PROWAG). DPS ROW Inspector Brian Sotero oversaw the work and signed off on completion.
The Result
A properly repaired driveway apron on a new pipe, built and restored to Montgomery County standards with county inspector sign-off — done right from the pipe up.

Why Culvert Work Requires a Specialist
Replacing a culvert pipe in Montgomery County isn’t a repair any paving company can take on. It requires a county permit, compliance with the Public Right-of-Way Accessibility Guidelines, coordination with a DPS ROW Inspector throughout the job, and full restoration of the right-of-way to county MC-301.03 standards before the inspector signs off. When the work is inside the public right-of-way, a tree protection plan may also be required before any excavation begins.
We handle the full job — excavation, pipe, stone base, asphalt base, topping, and right-of-way restoration — and we’ve done it regularly enough that the county process isn’t a reason to avoid the work.
