Question 1

Do I need a permit to repave my driveway or replace my sidewalk in Livingston?

Accepted Answer

For repaving an existing driveway within your own property, Livingston Township generally does not require a permit. However, any work that involves a curb cut, changes to the driveway apron, or construction within the public right-of-way requires a Road Opening Permit from the Township Engineering Office, along with a surety bond and proof of insurance. Sidewalk construction or alteration within the right-of-way requires a separate Sidewalk Permit. Roca handles both applications and builds aprons and sidewalks to township code standards — typically a minimum 4-inch-thick sidewalk slab with a 6-inch-thick apron section where the driveway crosses the walk.

Question 2

My Livingston driveway has a lot of cracks and low spots — does it need full replacement or can it be overlaid?

Accepted Answer

It depends on the base. If the cracking is surface-level oxidation or minor fatigue cracking without significant low spots, settlement, or edge failure, an overlay over a sound base can add 10 to 15 years of life. But if you have alligatoring across large areas, spots where the surface moves underfoot, or persistent low spots that collect water — all common on driveways in Livingston's clay soil where the base was never properly prepared — those are signs the base has failed. Overlaying a bad base just delays the problem by a few years. We assess the existing base on-site and give you a straight answer before any work starts.

Question 3

How do retaining walls fail in Livingston, and what does proper construction look like?

Accepted Answer

The two main causes of retaining wall failure in Livingston are hydrostatic pressure and frost. Clay soil holds water, and water pressing against the back of a wall that has no drainage path will push the wall outward over time — you'll see bowing, leaning, or full collapse. Frost adds a second mechanism: water in the soil freezes and expands, ratcheting the wall outward each winter. A properly built retaining wall includes gravel backfill directly behind the wall face, a perforated drain pipe at the footing to carry water away, and weep holes through the face. Walls taller than 3 to 4 feet typically require engineering drawings and a Livingston Township permit. Roca manages that process.

Question 4

What is the best time of year to pave or do concrete work in Livingston?

Accepted Answer

Late spring through early fall is the ideal window — roughly May through October — when pavement and air temperatures stay comfortably above 50 degrees Fahrenheit. Asphalt laid in cold weather doesn't compact properly, and fresh concrete poured below 40 degrees requires cold-weather precautions that add cost and risk. For sealcoating specifically, the pavement surface needs to be above 50 degrees and the weather forecast needs to be dry for at least 24 hours after application. One important note: never sealcoat fresh asphalt. New pavement needs 6 to 12 months to cure before sealer goes down, so a driveway installed this fall should wait until next summer or fall for its first coat.
