Deck Casting
Rafael Ocampo brings 20 years of trade practice prior to founding the company in 2016, pouring every pool surround to handle local soil conditions. Rialto sits over dry alluvial gravel and sand that shift when water drains off pool copings. Without an isolated bond beam and deep perimeter edges, ground movement cracks the slab corners within three seasons. We dig footings 12 inches deep along the shell edge to lock the surround firmly into stable subgrade.
Wind through the Cajon Pass strips surface moisture from fresh concrete faster than normal bleed water can rise. According to the Portland Cement Association, rapid surface evaporation exceeding 0.2 pounds per square foot per hour generates plastic shrinkage cracks across open flatwork. In Rialto, afternoon gusts routinely drive evaporation past that threshold. We counter this by applying evaporation retardants and mist barriers during placement.
Operating under CSLB C-8 licensing and maintaining liability insurance on every job, our crews pour 4-inch slabs over a 4-inch base of crushed aggregate compacted to 95 percent density. We place closed cell foam expansion strips between the deck and pool coping to prevent shell shearing. Control joints are cut every 8 to 10 feet within twelve hours of finishing, guiding stress relief before summer heat creates random surface fractures.
Deck Damage
Gaps wider than a quarter inch between your concrete deck and the pool shell reveal subgrade settlement. Splashing water enters these open joints and erodes the sandy soil beneath the bond beam. Left uncorrected, the slab drops and cracks adjoining coping stones within months.
Fine spiderweb surface fractures appear across Rialto decks poured without wind protection. Santa Ana gusts drying wet concrete at 90 degrees pull moisture from the top layer before the cement hydrates. These shallow fissures trap dirt, absorb pool chemicals, and flake off by winter.
Water standing against the pool edge looks like a harmless puddle after swimming, but it points to reverse slope settlement. Puddled water seeps through micro fissures, saturating the alluvial soil underneath. Over two seasons, saturated soil shifts and heaves the surrounding deck.
When one section of deck rises a half inch above another, it creates a direct tripping edge around the water. Shifting wash ground causes uneven subsidence under pool foot traffic. Delaying replacement risks swimmer injuries and forces costly underpinning of adjoining plumbing lines.
Standard Scope
Every pool deck we install around Rialto properties meets rigorous specifications designed to prevent cracking from sandy ground movement, Cajon Pass wind exposure, and intense summer sun.
We break out cracked concrete using hydraulic breakers, keeping rubble away from your pool shell and hauling it off site.
We inspect the cleared ground for soft pockets or voids near pool walls, replacing uncompacted dirt with clean structural fill.
A 4-inch layer of crushed aggregate is vibrated to 95 percent compaction, preventing wash ground from sinking under foot traffic.
We pour 4000 PSI concrete mixed with low water ratios, offering salt resistant additives for chlorine and saltwater pool systems.
Closed cell foam joint material isolates the deck from the pool shell, preventing coping damage during seasonal ground movement.
Number 3 steel rebar is tied in an 18-inch grid on chairs, holding slabs flat and tripling resistance to ground shear stress.
We wash down adjoining hardscape, clean pool filters of construction dust, and magnet sweep lawns for metal ties and fasteners.
Every project includes a written workmanship guarantee against defects in how it was built alongside manufacturer warranties on materials.
Deck Options
Choosing the right surface finish for your Rialto backyard balances heat absorption during 100 degree summer days against the grip needed on wet concrete to keep swimmers safe around the coping.
| Option | Lifespan | Suited Property | Maintenance | Cure to Walk |
|---|---|---|---|---|
| Broom Finish | 30 to 40 years of service life | Active family yards on standard budgets | Power wash every 12 months | 2 to 3 days for foot traffic |
| Kool Deck Coating | 15 to 20 years with maintenance | Sun exposed pools needing cooler surfaces | Reseal topcoat every 3 years | 3 to 4 days for full use |
| Rock Salt Finish | 30+ years on compacted rock base | Rialto ranch homes built in the 1970s | Penetrating sealer every 2 years | 3 days for light walking |
| Stamped Texture | 25 to 35 years when protected | Zero lot line yards with tight access | Wash and acrylic seal every 2 years | 3 to 5 days before pool use |
During the on site visit, we evaluate your pool orientation, shade cover, and foot traffic patterns before recommending the finish that fits your yard.
Rialto Ground
Cajon Pass wind gusts exceeding 40 miles per hour dry wet pool decks prematurely, while summer sun pushes unshaded concrete surface temperatures past 140 degrees.
According to the USDA Web Soil Survey, soils across Rialto consist heavily of Hanford coarse sandy loam and Tujunga wash gravels washed down from the San Gabriel Mountains. These granular deposits drain moisture rapidly but lack cohesive clay particles, meaning pool splash out and irrigation water wash through the subgrade quickly. When wet subgrade dries out under 100 degree heat, the ground settles unevenly beneath rigid concrete pool surrounds.
Pool coping details must absorb this movement independently. In San Bernardino County, where 63.5% of homes are owner occupied and backyards feature pools installed from the 1970s onward, bonding a deck directly to the pool beam causes cracking during seismic tremors or ground settling. We install closed cell polyolefin foam expansion joints with removable pull caps, filling the top half inch with elastomeric silicone sealant that keeps water out of the subgrade.
How We Pour
From our initial elevation layout to final joint sealing, every step protects your pool coping and prevents premature cracking caused by Rialto winds and shifting alluvial subgrades.
We measure slopes, test drainage away from the pool coping, and check existing soil stability. Every estimate is measured and written on site
You select your finish while we file permit plans with the Rialto Building Division, locking in your pour date once plans clear.
We break out old slabs, inspect the coping bond beam, compact fresh rock base, and haul broken concrete to a local recycling yard.
Steel rebar is placed on chairs, isolation foam is fitted at the coping, and a 4000 PSI mix is poured, supervised directly by Rafael Ocampo.
We tool expansion joints, seal coping perimeters with silicone, wash adjacent areas clean, and present the completed project paperwork.
Cost Drivers
Every backyard pool deck in Rialto presents distinct physical conditions, from narrow side gate access to shifting alluvial wash soil, that determine the crew hours and reinforcement needed.
Square footage, total linear footage of pool coping, and thickness requirements for patio furniture dictate basic material volume.
Alluvial wash ground requiring deep excavation and extra crushed aggregate base to prevent settlement moves the site preparation total.
Access paths under 48 inches wide require motorized buggies or concrete line pumps instead of direct truck chutes, adding labor hours.
Applied Kool Deck coatings, acid wash textures, or multi-step stamp patterns require specific surface timing evaluated on site.
We inspect your yard access, measure pool dimensions, and test subgrade stability on site before delivering a firm, itemized proposal. (909) 341-1928 or send us a message.

Client Reviews
Read direct feedback from Rialto property owners who hired our crew to pour, reinforce, and finish concrete pool surrounds across the Inland Empire.
“Our 800 square foot pool deck had sunk two inches away from the bond beam. The crew tore out the old broken slab, laid 4 inches of crushed rock, and poured a broom finish surround in four days. The new expansion joints around the coping look clean and tight.”
“We have an older 1974 ranch home with only 38 inches of side gate clearance. They used buggies to haul out 450 square feet of cracked aggregate deck without damaging our stucco, then poured a rock salt finish that stays cool under the afternoon Rialto sun.”
“Rafael Ocampo walked the entire 650 square foot deck with us to check slope drainage and verify the silicone seal along the pool tile. Having a written workmanship guarantee against defects in how it was built gave us real confidence, and the yard was left spotless.”
Common Queries
Clear answers to the structural and permitting questions homeowners ask before demolishing and replacing a concrete pool deck in Rialto.
Total square footage, coping edge detail, and subgrade preparation move your estimate most. Excavating unstable wash dirt and adding a 4-inch compacted aggregate base increases site preparation labor, while tight side yards under 48 inches require pumping equipment. Chosen decorative textures like salt finishes or Kool Deck coatings also adjust material time.
A standard pool deck installation takes 3 to 5 working days from demolition to final clean. Narrow yard access, extensive coping repairs, or high Cajon Pass winds that halt pouring can stretch that schedule. You can walk on the fresh concrete after 48 hours, but we advise waiting 7 full days before returning heavy patio furniture and reopening pool access.
Every pool deck includes demolition, 4 inches of compacted base rock, steel rebar reinforcement, and coping isolation joints. We include pool filter cover protection and subgrade soil compaction as standard line items on your estimate rather than charging them as surprise extras. The crew also washes down adjoining flatwork and hauls away all construction rubble.
Yes, replacement pool decks adjacent to pool coping require a building permit filed with the City of Rialto Building Division. We handle permit paperwork and schedule the required pre pour inspection to verify rebar clearances and base compaction before concrete arrives. Work that involves pool barrier modifications or retaining walls over 4 feet is also coordinated.
Early spring and late autumn provide the most stable conditions for pool deck pours in Rialto. Daytime temperatures between 65 and 75 degrees allow concrete to cure slowly without excessive water loss. Pouring during summer heat waves exceeding 100 degrees requires continuous misting barriers and early morning starts, adding curing supervision time to the project.
Your installation comes with a written workmanship guarantee against defects in how it was built and standard manufacturer warranties on concrete mixes. This coverage protects against structural installation failures and bonding issues. Neither warranty covers hairline surface crazing caused by natural ground movement or normal surface wear from foot traffic and prolonged sun exposure over decades of backyard use.
We pour 4000 PSI commercial mixes sourced from CEMEX and CalPortland, reinforced with grade 60 steel rebar. For expansion joints along the pool bond beam, we install Deck-O-Foam closed cell foam and Sonneborn Sonolastic SL1 elastomeric sealant. For sites needing heat relief, we apply genuine Kool Deck coatings to lower surface temperatures under direct summer sun.
No, you do not need to remain on site during demolition or concrete placement. Before the crew arrives, please clear side gates, keep pets indoors, and turn off pool pump timers. You should stay off the fresh concrete for 48 hours after we finish. If questions arise while work is underway, you can reach Rafael Ocampo directly by phone for an update.
