Jurupa Valley Concrete Pro draws a lot around the heaviest axle that crosses it rather than the number of stalls painted on it, and pours the trailer bays and dock approaches to match.

Who calls us
A parking lot is sized by weight, not by area. A car does nothing measurable to concrete; one loaded five-axle rig turning in off Limonite Avenue does more in a single movement than a year of commuters. So the work starts with a count of what arrives loaded and where it stops, and the stalls are fitted around the answer rather than the answer around the stalls.
Jurupa Valley Concrete Pro was founded in 2025 by Daniel Reyes, who spent 12 years on Inland Empire crews before it, and he sets the depths on every lot himself. Commercial ground in this city means two things: the distribution corridor through Mira Loma, where the tenant is a carrier or a freight operator, and the smaller frontage lots on Limonite and Van Buren serving markets, clinics and churches.
Lots go in under a CSLB C-8 concrete license with liability insurance on every job. A new or reconfigured one is a building permit at the Building and Safety Department, filed with a grading and drainage sheet and an accessible parking layout, and this city has only issued its own since it incorporated in 2011, anything older than that was signed off by the county. Every lot carries a written workmanship guarantee against defects in how it was built.
Warning signs
Water squeezed out of a joint as a wheel passes, drying to a gray fan across the surface, is base being pumped up through the slab. Under the flats that base is river sand, and every axle carries a little more of it away. Sealing the joint traps the fault underneath.
Run a boot across a lane joint and feel a step: the two panels have stopped carrying the wheel together. With no dowel through the joint the leading edge takes the whole axle and drops while the far side stays put, and each crossing after that breaks the lip back further.
Set a level across an accessible stall or the aisle beside it and any reading past 2 percent is a finding waiting to be written. Settlement causes it and so does an old overlay, and neither is answered with paint, because the surface itself has to come out and go back to grade.
Concrete crumbling along the outside of a bay where trailers swing wide is an edge with nothing under it. The sand shoulder beside the slab washes out first, the edge is then holding weight over air, and it snaps away in lengths instead of cracking in a line.
On every lot
Eight things every commercial lot here gets, none of them held back to be priced later. Each answers what this ground does to concrete: sand that travels once it is wet, axles that stop in the same square yard daily, and a plan check that reads the route in.
We count what arrives loaded across a working week, and the lanes and standing bays are drawn to the heaviest of it.
Stalls at 5 inches, drive lanes at 6, dock approaches and trailer bays at 8, all of it in a 4,000 psi commercial mix.
River sand is moisture conditioned and rolled, and any pocket that pumps under a loaded truck is dug out and replaced.
Caltrans Class 2 aggregate laid and compacted in layers, with the density tested and recorded before a form goes down.
Smooth steel dowels through every construction joint on a driving line, so both panels take the axle and not one edge.
Contraction joints sawn within 12 hours in panels kept near square, set out to land between two stalls and never through one.
Van and car accessible stalls, the access aisle and the route to your door formed to slope and checked with a level.
The surface meets your inlets at the elevations the drainage review approved, and every panel is checked before we leave.
Choosing a surface
Four ways to cover a commercial lot in this city, set against the traffic each takes, how long it stands here, what it asks of you afterward and how long the area is shut. What picks the row is the heaviest vehicle that stops on it, never the size of the site.
| Option | Traffic it takes | Years here | What it asks | Shut for |
|---|---|---|---|---|
| Asphalt paving | Staff and visitor cars, no delivery route | 12 to 15 years in this heat | Seal at 3 years, overlay at 12 | 2 days, cars back the same week |
| Concrete at 5 inches | Car stalls and the aisles between them | 20 to 30 years | Reseal the joints every 5 years | 1 to 2 days, then 7 to cure |
| Concrete at 6 inches | Drive lanes, fire lane, refuse approach | 25 to 35 years | Reseal joints, sweep the grid yearly | 2 days a section, then 7 to cure |
| Concrete at 8 inches | Dock approaches and trailer standing bays | 30 to 40 years | Check the doweled joints once a year | A weekend a section, 28 before rigs |
Depth and dowels are the two things no one can add afterward. Asphalt opens soonest and moves first where a rig stands still through a July afternoon.
On this ground
Two things decide a lot in this city: which corridor it stands in, and a subgrade of river sand that has to be proved before anything is poured on it.
Mira Loma is the commercial half of Jurupa Valley. Warehousing spread across it from the 1990s onward, and the sites either side of Etiwanda and Limonite are distribution buildings first, so what we are asked for is a truck apron, a dock approach or a trailer standing bay far more often than a shopper car park. That decides the drawing: the lanes and the bays are laid out to a wheel load, given 8 inches with dowels where the rigs stop and turn, and the stalls go in around them.
The paperwork is the other half. A good many yards here were surfaced while this was unincorporated county land, before there was a city to review them, so an old lot brought back for a permit usually comes back marked on the accessible stalls, the access aisle and the marked route in to the office door. That work lands on the same sheet as the paving and the drainage, which is why we draw all three together rather than treating the striping as a job for afterward.
Five stages
One crew, and the same person at the traffic count and at the pour. The permit and the drainage sheet are filed by us, and the order the sections close in is agreed with whoever runs the site before a saw touches the surface.
Daniel Reyes walks the lot during a working shift, counts what arrives loaded and marks where trailers stop, stand and turn.
Lanes, bays, stalls and the accessible route are drawn with a depth on each, then filed for plan check and drainage review.
The lot is split into sections that can each be shut on their own, and the order and the dates are set in writing around your deliveries.
Old surface out and hauled, subgrade proved with a loaded truck, base compacted in layers, dowels set at each section joint.
Placed at first light, joints sawn within 12 hours, cured 7 days before cars go back on it and 28 before a loaded rig crosses.
Where the number comes from
Square footage sets the floor and the traffic sets everything above it. A site with six dock doors and a site with none can measure the same and still be a fortnight apart in work. Every estimate is measured and written on site.
Deep concrete with dowels under the truck route, 5 inches under staff stalls. That split moves the figure further than area does.
One closed fortnight is a single mobilisation. Keeping every dock live means small sections, weekend pours and more joints to dowel.
River sand rolls up well. A pocket that pumps under a loaded truck comes out and is replaced, and that is settled in the open cut.
Resetting inlets, regrading to a reviewed sheet and bringing stalls and the path of travel to slope are work the area never shows.
No figure is taken off a satellite image of your roof line. The walk costs nothing, the number is written on your own lot, and we call back within 1 business day. (951) 903-5460 or send us a message.
Send the form or call the yard on Limonite Avenue, and someone rings you back within 1 business day to book the walk. We count the loaded traffic, measure the lot and write the figure while we are standing on it, and none of that is charged for.
Site owners
Left on Google and Facebook by the people who signed off the closure dates and had to keep their gates working while we poured. All three are commercial lots rather than driveways.
“Our trailer bays off Etiwanda had rutted so deep the yard hostler was bouncing through them. They took the standing area out, proved the sand under it with a loaded truck and poured 8 inches doweled back into the lane. Two peak seasons on and it is still flat.”
“A tenant complaint put our accessible stalls in question and it grew into a repour of the whole frontage. Daniel drew it, filed it with the city and met the inspector, and we passed first time. The work ran across two Sundays so the store never lost a trading day.”
“We could not shut the dock for a week, so they split the approach into three and took one each weekend. Every section was doweled into the last and you cannot feel a joint under a wheel now. They swept the yard clean each Monday before our trucks came back in.”
FAQ
Depths, dowels, permits, phasing and what the guarantee actually covers, answered for a commercial lot in this city rather than for paving in general.
Area sets the floor, then the share of it that carries trucks. Eight inches with dowels under a dock approach is a different build from 5 inches under staff stalls, so two lots the same size can be a fortnight apart in labor. What lies under the old surface comes next, and after that how much of the site has to keep working while we are on it. Every estimate is measured and written on site.
Five inches under car stalls, 6 through the drive lanes, the fire lane and the refuse approach, and 8 where dock approaches and trailer bays take turning rigs and standing landing gear. Depth follows the heaviest thing that stops on each area, because one loaded axle asks more of a slab than a year of commuter traffic does. Which depth lands where is drawn on the plan you sign.
Yes. A new or reconfigured commercial lot is a building permit at the Jurupa Valley Building and Safety Department, filed with a grading and drainage sheet and an accessible parking layout. Anything touching the driveway approach or the public right of way takes an encroachment permit from Public Works alongside it. We prepare both, file them and meet the inspector.
Yes, by splitting it into sections small enough that your remaining lanes still route. Each one is broken out, based and poured inside its own closure, and the joint back into the slab beside it carries smooth dowels so a wheel crosses the pair as one. Cars go back on after 7 days and a loaded rig waits 28. The order and the dates are agreed before the price is fixed.
Santa Ana River sand with rounded cobble through it. It drains fast and compacts well, which is part of why the flats carry warehousing at all, but the top of it is loose and it keeps consolidating under weight that stands in one place. So it is moisture conditioned, rolled and then proved with a loaded truck, and anything that pumps under the wheels is dug out before base is ordered.
The count comes off the total number of stalls on the approved plan, with at least one of them van accessible, and the stall, its access aisle, the slopes and the marked route to your door each have set dimensions. A lot striped before this city began reviewing its own plans in 2011 rarely still meets them, so an old lot redrawn on paper usually gains stalls on the ground.
Wherever something heavy stops, yes. Afternoons here reach the mid-90s through July and August, asphalt binder softens at that point, and a rig standing on it presses in while the turns shove into waves. Concrete carries the same rig at the same temperature without moving. For a lot that sees nothing heavier than a delivery van, asphalt is still the cheaper cover, and that is the honest answer.
You get a written workmanship guarantee against defects in how it was built, and its terms sit on the estimate you sign. What it covers is our work in and below the slab: the ground we proved, the compaction we recorded, the thickness under each part, the steel and the dowels, and the sawn joints. Wear, staining, a section driven on before its cure was up and plant heavier than the lot was drawn for are not.
Where we pour
Sites in the eight towns nearest the yard on Limonite Avenue, with the straight-line distance beside each. Every lot is walked before a figure is written.
Four jobs measured on the same walk as the lot and, where they meet the paving, poured inside the same closure by the same crew rather than booked as a second visit.
Bases for light columns, the bollards at your doors and refuse enclosure walls.
The public walk over your frontage, and the marked route from stall to door.
The floor the dock doors open onto, jointed around the racking that stands on it.
Cutting one bay out of a working lot, or a trench for a new drainage inlet.
One call starts the count. Someone rings back within 1 business day to arrange a walk while your gate is working, and by the time we leave you have a written figure, a depth for each part of the lot and dates that fit around your deliveries.
