Grand Terrace sits on a bench of old alluvium between Blue Mountain and the Santa Ana River. The ground is firmer and better drained than the floodplain below, and rockier toward the mountain.
The name is the geology. The terrace was laid down by the river long before the river cut down to where it runs now, west of the 215, so the flats along Mount Vernon Avenue and Barton Road are compact sandy soil that carries a slab well. East of Michigan Street the streets climb toward Blue Mountain and the ground turns to decomposed granite on a slope, which drains fast but moves when it is cut and left bare. Two ends of one small town, and they take a different base.
So the first thing we do is find out which end you are on. On the flats we strip to firm material, lay 4 inches of Class 2 base and plate-compact it. Against the mountain we cut to solid decomposed granite and pour on it, and any wall that holds the cut is footed into it and drained behind. Every slab here gets number 3 steel on an 18-inch grid, because this end of the valley is a few miles from the San Jacinto fault and a reinforced slab cracks in a line rather than a map.
Grand Terrace was groves and pasture until the 1970s, and most of its houses went up in the decade either side of incorporation in 1978. Those slabs are near 50 years old, so the work here is replacing them and adding what the yard never had.
A Grand Terrace driveway from the 1970s is a single car wide and was poured thin, so it has been cracking under two cars for years. We cut and haul the old slab, widen the approach with the city's sign-off at the curb, and pour 4 inches on compacted base with steel through it.
Patios here start with the builder's 10 foot slab at the back door, and most tract lots between Barton Road and DeBerry Street have room to double it. We pour 4 inches on compacted base, joint it every 10 feet, and dowel it into the old slab so the two pieces move as one.
Stamped concrete in Grand Terrace is asked for around pools and on the front walk, where an owner wants the look of stone on a slab that can be hosed down. We cast an ashlar or flagstone pattern into a 4 inch slab, color it to the house, and seal it in 2 coats so it holds.
Sidewalks on the Grand Terrace grid are city property to the back of the walk, and the panels along Mount Vernon Avenue have lifted where the parkway trees are 40 years old. We take out the permit, cut roots behind a barrier, and dowel new panels to the old so the joint is flush.
Garage floors in Grand Terrace are the original 1970s pours, dusting and cracked at the door. Where the slab is sound we grind and coat it. Where it has dropped at the apron we break it out, recompact the base and pour a new 4 inch floor over a vapor barrier so the coating holds.
A dark slab in a Grand Terrace back yard is unusable by early afternoon from June to September. We pour a light integral color with a salt or broom finish, which stays cool enough to cross barefoot, and exposed aggregate where a drive needs grip on the slope toward Blue Mountain.
Retaining walls are the job on the east side of Grand Terrace, where the streets climb toward Blue Mountain and a lot steps 3 or 4 feet at the fence. A wall in decomposed granite is footed into firm material, drained with rock and a perforated pipe, and engineered past 4 feet.
Interior slabs in Grand Terrace come with the garage conversions and the backyard units the state now permits on a tract lot. We pour over a 10 mil vapor barrier, trowel the slab flat enough for tile, and cut the joints on a grid that follows the room rather than the crew.
Our Fontana yard is under 10 miles from Grand Terrace, down the 10 and the 215 to the Barton Road exit, so a crew is on site inside half an hour and a return visit costs us nothing to schedule. Plans go to the City of Grand Terrace Building and Safety Division at the civic center on Barton Road, and a small city means a short counter. A job on the south edge along Main Street may fall in Highgrove, which is unincorporated Riverside County, and the county issues that permit instead.
The town is one grid, and the grid tells you the era. The streets between Barton Road and DeBerry Street, off Mount Vernon Avenue and Michigan Street, are the 1970s and 1980s tracts, with single-width driveways and a 10 foot patio slab that the builder poured thin. The Gage Canal still runs across the town from the days it watered the groves, and the older houses along it sit on larger lots with the room for a full pool deck or a drive that turns.
Blue Mountain sets the east edge and the weather. The slope above the high streets sheds water in a winter storm faster than a level yard can take it, so a patio on that side is graded away from the house and the wall behind it is drained. Summer is the other constraint. This corner of the valley runs past 100 degrees from July into September, so we pour from 6 in the morning and finish before the surface dries ahead of the set. December to March costs a handful of days.
Four stages, one crew, and a written figure from the first visit. Grand Terrace is close enough that Andre Whitfield measures in person, and the crew that measured is the crew that turns up to pour.
Andre Whitfield measures the slab, checks the fall from the house, notes which end of town the ground is on, and writes the figure on the spot.
We file with the City of Grand Terrace Building and Safety Division, or with Riverside County on the Highgrove edge. No counter for you.
The thin 1970s slab is cut and hauled, the ground is cut to firm material, and 4 inches of Class 2 base is laid and plate-compacted.
Two to 3 days on site for most jobs. Joints are cut within 12 hours, you walk on it after 24 hours and park on it after 7 days.
Call or send the form and we will call you back within 1 business day to book the visit. The measure and the written figure are free, and with the yard under 10 miles away we are in Grand Terrace most weeks.
Reviews
Our reviews are left on Google and Facebook by homeowners across the towns we cover from Fontana. Grand Terrace is one of them, and the driveways and patios behind them are the ones described here.
“Our house south of Valley is one of the old steel-town builds and the driveway had never been replaced. They broke out 520 square feet, screened the cobble out of the base and poured 5 inches. Andre cut the joints himself before he left.”
“We are in one of the newer tracts up north and the builder patio was cracked across the middle in three years. Fontana Concrete Pro dug it out, put a proper base under it and poured 320 square feet with joints on a 10-foot grid. No cracks after two summers.”
“The slope at the back of our lot in Jurupa Hills was moving every winter and taking the fence with it. They poured a 40-foot wall on footings to 24 inches with drainage behind it. Two wet seasons on and there is not a crack in it anywhere.”
What Grand Terrace homeowners ask before booking, from what moves the estimate and which counter issues the permit to how the ground differs between the flats and the slope under Blue Mountain.
Area, then what comes out first. Nearly every Grand Terrace job starts with a 1970s slab to cut and haul, and the haul is on the estimate. Access matters next, since a tract side yard here runs about 5 feet and a mixer cannot reach the back, so the concrete is barrowed. Thickness, steel and finish move it after that. Every estimate is measured and written on site, so the figure is measured and not guessed.
Not for a patio, a path or a slab at grade in your own yard. Yes for a retaining wall over 4 feet, a footing that carries a roof or a cover, and any work at the sidewalk or the driveway approach. We apply to the City of Grand Terrace Building and Safety Division, or to Riverside County if your lot sits in Highgrove past the city line, and we meet the inspector.
Yes, on both ends, for different reasons. The flats along Barton Road and Mount Vernon Avenue are old river terrace, compact and well drained, and a slab on 4 inches of compacted base there stays put. The streets up against Blue Mountain sit on decomposed granite, which carries a slab well once it is cut to firm material but slumps if it is left loose on a slope, so a cut there gets a drained wall the same week.
The yard is under 10 miles away by the 10 and the 215, so the drive is inside half an hour and it is not on your estimate. You get the same call-back within 1 business day as any other town we cover, and because it is this close, the person who measures is the person who runs the pour. The work carries a written workmanship guarantee against defects in how it was built.
Roughly 10 days from the first cut to the first car. Tear-out and base take a day, the pour a second, and then the concrete cures 24 hours before foot traffic and 7 days before a vehicle. Patios and walks are done sooner at both ends. From July to September we pour at first light, because a slab finished at 100 degrees dries on top before it sets underneath.
Yes. Colton wraps the north and west of Grand Terrace, Loma Linda is over the ridge to the northeast, and Highgrove lies south across the county line in unincorporated Riverside County. All three are on the same 215 run from Fontana, so a job on any of those streets is booked and run the same way as one on Barton Road.
Grand Terrace shares a line with Colton and Loma Linda in San Bernardino County and with Highgrove and Riverside across the county line, and we cover all of them from the same yard. If your street sits on one of those lines, the page next door will do.
