Licensed Concrete & Masonry in Pacoima, CA

Concrete reaches initial set in 24 to 48 hours, can support foot traffic in 24 to 48 hours, vehicle traffic in 7 days, and reaches its design strength (typically 4,000 PSI) at 28 days. Full curing continues for months. Proper curing procedures during the first 7 days are critical for achieving maximum strength and durability.

Residential driveways should be a minimum of 4 inches thick for passenger vehicles. Heavy vehicle areas should be 5 to 6 inches. Commercial drives typically require 6 to 8 inches. Proper base preparation (4 to 8 inches of compacted gravel) is equally important as concrete thickness.

Concrete cracks from shrinkage during curing, settlement of the base material, freeze-thaw cycles, excessive load, inadequate thickness, improper control joint placement, poor mix design, insufficient reinforcement, or tree root pressure. Some hairline shrinkage cracking is normal and expected.

Stamped concrete is decorative concrete that is imprinted with patterns while still wet to resemble brick, natural stone, slate, tile, or wood. It is more affordable than natural materials, requires less maintenance, and offers a wide range of color and pattern combinations. It should be sealed every 2 to 3 years to maintain its appearance.

A basic broom-finished concrete driveway typically costs $6 to $12 per square foot installed. Stamped concrete ranges from $12 to $20 per square foot. Exposed aggregate runs $10 to $18 per square foot. Costs vary based on thickness, site preparation, reinforcement, finish type, and regional labor rates.
