Interlock parking areas fail in a very predictable pattern: ruts where wheels track, dips at the entrance where vehicles turn in, and a bin pad that has sunk under something far heavier than a car. All three are base depth rather than surface problems, and all three come back if the rebuild does not account for the real load.
The single most useful piece of information on a parking area quote is what actually drives on it and where.
A passenger vehicle bay wants one base depth, a fire route or a delivery lane wants considerably more, and the pad a waste bin is tipped on takes a concentrated load from a truck with a lifting arm that dwarfs everything else on the site.
Most of the failed interlock parking we look at was built to a single specification across the whole lot, so the bays are fine and the lanes and the bin pad have collapsed. Rebuilding those to the same depth buys about three years.
So the survey comes first: which vehicles, how often, and along which lines. Then the base is specified per zone rather than per lot. See what base repair involves, how sunken driveways rut the same way, and how property management scopes it across sites.
Parking Areas
How It Runs
Four steps to a lot that stops rutting
Survey the traffic
Which vehicles use which lines, and how often. Bays, lanes, fire routes and bin pads are four different specifications.
Open the worst zone
A test lift where the failure is deepest shows what depth exists now and how far short of the real load it falls.
Rebuild per zone
Base depth and compaction specified for the traffic each area takes, rather than a single figure applied across the whole lot.
Stage so the lot works
Sections are sequenced with the property so enough spaces and a route through stay usable for the duration.
Bin Pads
The waste pad is the hardest spot on any lot
A refuse truck sets down enormous concentrated load through a small footprint, and it does it in the same spot every week. A bin pad built to bay specification will always sink.
It needs its own base build, and on many sites it is worth doing in concrete rather than interlock for exactly that reason. We will say so rather than relaying it.
Because the vehicles are not evenly distributed. Lanes, fire routes and the spaces nearest an entrance see far more traffic than the far corner of a lot does.
A refuse truck delivers concentrated load through a small footprint in the same spot weekly. A pad built to bay specification will always sink under that.
No. Work is sequenced with the property so enough spaces and a route through stay usable, and which zone comes first is agreed rather than assumed.
Yes, with the right base. The failures we see are specification failures rather than product failures, and the base is where the specification lives.
Roughly $14 to $25 per square foot depending on the zone and its required depth, with bin pads and fire routes at the upper end of that range.
Anything inside the work area comes up with the pavers and has to be reinstated. The quote says whether we are restoring it or leaving it to your line marking contractor, because doing it twice is a cost nobody planned for.
