Whether you need a new garage slab, a patio floor, or a replacement for a surface that has cracked and settled for years - proper base prep is what separates a floor that holds from one that fails.

Concrete floor installation in Chino starts with the ground beneath the slab - removing old material, grading the soil, compacting a gravel base - then pouring and finishing the surface before it sets. Most residential projects are completed in one to three days on-site, though the concrete needs about 28 days to reach full strength. PSB Chino Concrete Works handles demolition, base work, the pour, finishing, and City of Chino permit paperwork as part of every project.
The floors that fail in Chino almost always trace back to shortcuts in base preparation. Chino's clay soils shift with the seasons, and a slab poured over inadequately compacted ground will settle and crack no matter how good the concrete is. If your project involves converting a garage or adding a pool-side area, our garage floor concrete service covers those specific applications in detail.
Small hairline cracks are common and often harmless. But cracks wider than a quarter-inch, cracks where one edge sits higher than the other, or cracks that reopen after patching are signs the slab is moving from below. In Chino, this usually means the clay soil has been shifting with seasonal moisture changes - a problem that patching the surface will not fix.
If you hear a hollow sound when you tap the floor, or if certain areas feel like they flex underfoot, the ground beneath has settled or washed away. This is more common in older Chino homes where original base prep did not account for local soil conditions. An uneven floor is also a tripping hazard that tends to get worse over time.
When the top layer peels in thin flakes, develops small pits, or leaves a residue on your shoes, the surface has started to break down. This happens when concrete was finished poorly, never sealed, or has been through years of moisture and heat cycles - all common in Chino's climate. Once surface deterioration starts, it accelerates and patching rarely holds.
Water pooling on a concrete floor rather than draining away - or a floor that stays damp after dry weather - points to a drainage slope problem or a slab that has settled unevenly. In Chino, where summer irrigation is heavy and clay soils hold moisture, poor drainage around a slab can cause the ground beneath to shift over time.
Every project starts with a free on-site assessment and a written quote that separates demolition, base preparation, materials, and permit fees. We handle the City of Chino permit process and coordinate the city inspection so you have a record that the work was done to code. Surface finish options run from a standard broom texture to a smooth trowel finish, exposed aggregate, or stamped patterns for areas where appearance matters. For outdoor areas connected to a pool or deck, our concrete pool decks service covers the specific slope and slip-resistance requirements for those surfaces.
We also handle full demolition and replacement of existing floors that have failed. Removing old concrete, correcting drainage issues, and starting fresh with a properly prepared base is often more cost-effective than repeated patching - and it produces a floor that actually stays flat. Slab thickness is specified in your written quote. Standard residential garage floors are typically four inches; floors supporting heavy equipment or intended for ADU use may go five or six inches.
For areas with no existing concrete - garages, patios, walkways, and interior rooms being added or converted.
Full demolition and fresh pour for floors that have cracked, settled, or deteriorated past the point of repair.
For Chino homeowners converting a garage to a living space - leveled, properly sloped, and built to residential standards.
Stamped, exposed aggregate, or polished finishes for garages, patios, and covered outdoor rooms where the look matters.
Much of Chino was developed on former agricultural land, and the clay-heavy soils throughout the city expand and contract with every wet and dry season. A concrete slab poured directly onto unprepared clay is set up for premature cracking from the first wet winter. Good base prep - compacted soil, gravel sub-base, sometimes a moisture barrier - is what gives a slab stable ground to rest on through Chino's seasonal cycles. The Portland Cement Association covers the technical standards for slab-on-grade construction, including the base preparation steps that are non-negotiable for durable results.
Summer scheduling matters too. Chino regularly sees temperatures above 95 degrees from June through September, and concrete poured in peak afternoon heat loses moisture too fast during curing - producing a surface that feels solid but develops fine cracks within the first season. We schedule pours for early morning during hot months and use curing compounds to slow moisture loss. We work throughout Chino and regularly handle floor projects in Ontario and Fontana, where the same soil and heat conditions apply.
We respond within 1 business day. We ask a few quick questions, then schedule a free on-site estimate - a price based only on a description is rarely accurate once we see the actual site conditions.
We measure the area, check the existing surface or soil, and note anything that could affect cost - tree roots, poor drainage, old slab that needs to come out first. You receive an itemized written quote before we do anything.
For most Chino floor projects, we apply for the city building permit before work begins. Once approved - typically a few business days to a couple of weeks - we schedule your start date and you clear the area and move any vehicles or stored items.
Day one: demolition and compacted base preparation. Day two or three: the pour, finish, and protection of the fresh surface. The city inspector visits during this window. You can walk on it in 24 to 48 hours - we walk you through the full curing timeline before we leave.
We respond within 1 business day - no obligation, no pressure. You will receive a written, itemized quote before any work is scheduled.
(840) 200-1378We excavate, compact the soil, and lay a gravel sub-base on every project before a single yard of concrete is ordered. That prep work is the step most contractors rush - it is also the step that determines whether your floor stays flat for 30 years or starts cracking in the second wet season.
We apply for every required building permit through the city and coordinate the inspection so you have a record that the work was done to code. An unpermitted slab can create real problems when you sell your home or try to finalize an ADU conversion - we make sure your project is fully above board.
Garage-to-ADU conversions are one of the most common concrete floor projects in Chino right now, and we have handled them throughout the city. We know what the residential slab standards require and how to assess whether your existing floor can be used or needs to come out. We cover 12 cities across the western Inland Empire.
Your quote separates labor, materials, demolition, and permit fees. If something unexpected comes up during site prep - an old slab that is thicker than expected, a drainage issue beneath the surface - we talk to you before we do anything that changes the price. No surprises halfway through the job.
The American Concrete Institute sets the professional standards we follow for mix design, reinforcement, and finishing - the same standards a city inspector is checking for. When both the contractor and the inspector are working from the same baseline, projects go smoother and the finished floor reflects it.
Pool-side surfaces need specific slope, texture, and slip resistance - different requirements from a standard floor pour.
