Why Choose Our Commercial Flatwork
Legacy General Services handles commercial concrete flatwork projects from small retail sidewalks to large warehouse floors. We work from engineered drawings, coordinate with general contractors, and meet commercial specifications.
Commercial flatwork demands higher-strength concrete, heavier reinforcement, and more precise joint layout than residential work. We engineer every pour for the specific loads and traffic it will carry.
We understand commercial timelines and coordinate large-scale pours with ready-mix batch plants, pump trucks, and finishing crews to keep your project on schedule.
All commercial work meets ADA requirements for accessibility and is installed to local building code specifications.
Signs You Need Commercial Flatwork
1. Parking lot deterioration
Extensive cracking, spalling, or settlement in parking lots creates liability exposure and a poor first impression for your business.
2. Warehouse floor damage
Cracked, uneven, or dusting warehouse floors slow operations, damage equipment, and create safety hazards for workers.
3. New commercial construction
New buildings require properly engineered flatwork for parking, pedestrian circulation, loading areas, and outdoor spaces.
4. ADA compliance issues
Sidewalks and entrances that don't meet ADA slope and surface requirements need replacement to avoid legal liability.

FAQs About Commercial Flatwork
How thick should commercial concrete be?
Commercial parking lots typically require 6-8 inches of concrete with wire mesh or rebar reinforcement. Warehouse floors range from 5-8 inches depending on rack loads and forklift traffic. Engineering specifications should always be followed.
How long does a commercial parking lot last?
A properly designed and installed concrete parking lot lasts 25-30+ years with routine maintenance. Concrete significantly outlasts asphalt (10-15 years) and requires less maintenance over its life.
Can you pour concrete in phases to keep the business open?
Yes. We regularly phase commercial pours to maintain access for customers and deliveries. Phased pours require proper joint detailing between phases but allow businesses to continue operating.
