The number people ask first
$4,300 to $7,200 for a typical RV pad

Around Sanger and east Fresno County, reinforced pads install at $9 to $15 per square foot, so a 12-by-40 RV pad usually lands in that range. For heavy rigs or shop equipment, spend the extra on 5 to 6 inches of thickness with rebar rather than the minimum 4.

Drainage first

Water is the enemy: drainage before anything else

Sanger's terrain is flat, the Kings River is close, and between winter rains and season-long irrigation in every direction, the ground here spends real time wet.

Water that ponds against a slab soaks the soil under it, and saturated soil settles unevenly, which is how pads sink and crack. The fix is boring and cheap at pour time: slope the slab roughly a quarter inch per foot away from any structure, and make sure gutters and downspouts discharge beyond the concrete, not onto it. Retrofitting drainage after a slab has settled costs multiples more.

Base prep

Where good and bad pours part ways

1
Compacted base

Two slabs can look identical on day one and age completely differently. The difference is almost always the base underneath.

2
Correct thickness for the load

At least 4 inches for vehicle weight; 5 to 6 inches with rebar for heavy rigs or shop equipment.

3
Curing in the heat

Sanger spends weeks over 100 degrees. Concrete cures, it does not dry, so summer pours want first-light starts and deliberate wet or compound curing.

Hire with confidence

The five-minute license check

  • California requires a CSLB license (typically C-8 Concrete or B General Building) for any job of $500 or more.
  • The free lookup at cslb.ca.gov shows whether a license is active, bonded, and carrying workers' comp, and whether the board has disciplined it.
  • Ask what goes under the concrete and how thick the pour is; a price that seems too good usually thinned exactly what you never see.
  • Get grading and drainage in writing so water runs off the finished slab.

It is the single highest-value step in hiring, and it costs nothing.

Straight answers

Common questions

How much does an RV pad or shop slab cost in Sanger?
In the Sanger and east Fresno County area, a reinforced RV pad or shop slab typically installs for $9 to $15 per square foot, so a 12-by-40 RV pad usually lands between $4,300 and $7,200. Pads carrying vehicle weight should be at least 4 inches, and 5 to 6 inches with rebar for heavy rigs.
Why does drainage matter so much for concrete in Sanger?
Sanger sits near the Kings River with flat terrain and seasonal irrigation all around, so water that cannot drain away from a slab soaks the soil underneath. Saturated ground settles unevenly and lets slabs sink and crack. A proper pour is sloped about a quarter inch per foot away from structures.
What should a concrete bid in California include?
A complete bid names the CSLB license number (required for any job of $500 or more, verifiable free at cslb.ca.gov), pour thickness, base preparation, reinforcement, control joint layout, curing method, and demolition and haul-away if applicable.

Preguntas frecuentes

Cuanto cuesta una losa para RV o taller en Sanger?

Las losas reforzadas generalmente cuestan entre $9 y $15 por pie cuadrado instaladas. Una plataforma de 12 por 40 pies para RV suele costar entre $4,300 y $7,200. Para vehiculos pesados, vale la pena pagar 5 a 6 pulgadas de grosor con varilla.

Por que importa tanto el drenaje?

El agua que se acumula junto a una losa satura el suelo debajo, y el suelo saturado se asienta de forma desigual, lo que hunde y agrieta el concreto. La losa debe inclinarse un cuarto de pulgada por pie, alejandose de la casa.
