For most San Jose driveways and patios, reinforced concrete on a compacted rock base is the long-life choice. Asphalt and pavers each win in certain spots. The comparison prices are national HomeGuide figures for 2026 and are not our quotes.
Concrete or asphalt for a driveway?
Concrete lasts longer and needs less upkeep. Asphalt costs less at the start. Nationally asphalt is $5 to $12 or more per square foot against $6 to $15 for concrete. Asphalt softens in valley heat, needs resealing and is rare on home driveways here. It suits long rural drives in the south county where budget per foot matters most.
Poured concrete or pavers?
Pavers cost more and can be lifted and relaid. Poured concrete costs less and has no joints to weed. Nationally a paver patio is $10 to $17 per square foot. On expansive clay or beside a large tree, pavers have a real advantage because a lifted area can be reset. A slab is the better choice for clean lines, heavy loads and low upkeep.
| Surface | National installed cost (HomeGuide, 2026) |
|---|---|
| Concrete driveway | $6 to $15 per sq ft |
| Asphalt driveway | $5 to $12+ per sq ft |
| Plain concrete patio | $4 to $12 per sq ft |
| Paver patio | $10 to $17 per sq ft |
| Stamped concrete | $8 to $19 per sq ft |
How thick should a concrete driveway be?
A concrete driveway for cars should be at least 4 inches thick, and 5 to 6 inches where an RV, a work truck or a delivery vehicle will park. Edges and the section by the street are often thickened. On clay, the rock base under the slab matters as much as the thickness.
Do I need rebar or wire mesh?
On San Jose clay, yes. Rebar or wire mesh does not stop cracks, but it holds the pieces tight and level when the soil moves. Rebar on supports is the stronger choice for driveways. Mesh works in patios and walks if it is held up in the middle of the slab and not left on the dirt.
What PSI concrete do I need?
Most home flatwork is ordered in the 2,500 to 3,500 PSI range, with driveways at the upper end and higher strengths for heavy loads. Structural footings and slabs use the PSI on the engineer's plans. A stronger mix does not make up for a poor base or added water on site.
Is stamped concrete worth it?
Stamped concrete is worth it when looks matter and you accept the upkeep. It costs $8 to $19 per square foot nationally, needs resealing every few years, and repairs are hard to hide. For a front walk or a patio you see daily it adds a lot. For a side yard, plain broom finish is the better spend.
Should I seal my new concrete, when, and how often after that?
Sealing plain concrete here is optional, since there is no freezing or road salt to protect against. If you want to seal new concrete to resist oil and stains, wait until it has cured, commonly about a month, and follow the product label. Stamped and colored concrete should be sealed. Sealing costs $1 to $3 per square foot nationally.
How often depends on sun and traffic. Decorative concrete in full valley sun is commonly resealed every two to three years. Plain driveways can go much longer or stay unsealed. When water stops beading and soaks in darker, it is time.
Broom finish or smooth finish, and what works on a steep driveway?
Use a broom finish outdoors. It grips when wet and hides wear. A smooth steel-trowel finish is for garages and interiors and is slick in the rain. Sand finish and exposed aggregate sit between the two and suit modern homes.
A steep driveway needs a heavy broom finish across the slope, and on the steepest ones, grooves cut or tooled across the surface. Hillside streets in Almaden, Evergreen and the east foothills call for this. Smooth or sealed stamped finishes are unsafe on a slope in the wet season.
What does a hot tub pad need?
A hot tub pad needs to be flat, at least 4 inches thick and often 6, reinforced, and on a compacted base, because a filled tub with people weighs several thousand pounds. Check the maker's pad requirements. The electrical supply needs a permit and should be planned before the pour.
I want a shop slab for a vehicle lift or heavy equipment. What changes?
A slab for a vehicle lift or heavy equipment needs the thickness and concrete strength the lift maker specifies under the posts, plus rebar and good base. Tell us the lift model before the pour. Anchoring a lift into a thin slab is dangerous. No control joint should run under a post.
Do I need gravel under a slab, and do I need a vapor barrier?
Yes, on clay you need gravel under a slab. A compacted layer of crushed rock gives even support and a buffer between the concrete and soil that swells. Skipping it is the most common shortcut on low quotes here.
You need a vapor barrier under any slab that will be indoor space or receive flooring or a coating, including garage conversions and ADUs. It stops ground moisture from rising through the concrete. Outdoor patios and driveways do not need one.
My pad has to take delivery trucks. How is it built?
A pad for a delivery truck or refuse truck is built thicker, commonly 6 inches or more, with rebar, a stronger mix and a deeper base. Joints are placed and sometimes dowelled so wheels do not break the edges. The design depends on the truck weight, so give us the details.
My pool deck is worn. Resurface, pavers or new poured concrete?
Resurface a pool deck that is sound and level. National resurfacing figures for a pool deck are $3 to $6 per square foot. Replace panels that have sunk or tilted. Pavers are a good option around older pools where the backfill is still settling, since they can be relaid. Pick a light, textured finish in any case.
The patio is poured against the house. What goes between them?
An isolation joint, sometimes called an expansion joint. It is a strip of compressible material between the patio and the foundation so each can move without pushing on the other. It matters here because clay and earthquakes both move slabs. The top is sealed to keep water out.
