Surfacing Cost Guides: What Rubber, Turf, Epoxy and Concrete Cost

• Poured in place rubber: $15 to $25 per square foot.
• Artificial grass: $8 to $18 per square foot.
• Epoxy floor coatings: $5 to $12 per square foot.
• Polished concrete and grinding: $4 to $10 per square foot.
• Caulking and sealants: $4 to $10 per linear foot.

Each guide explains the factors for that surface.

1. Area. Larger areas cost less per square foot. Small areas carry fixed setup and edge costs.
2. What is underneath. Base preparation, drainage, slab repair, moisture treatment and removal of old surfacing are often the largest variables.
3. Materials and finish. Product lines, colors, patterns, thickness and the number of layers or coats change material cost.
4. Access and site conditions. Slopes, gates, stairs, distance from the work area to equipment and working around people all add time.
5. Schedule. Phased work, evening or weekend hours and tight deadlines can add cost.

A planning range is the span in which most installed projects of that type land. The low end usually means a larger, simple area with good access and a sound base. The high end usually means a smaller area, more preparation, tighter access or a more complex design. Your project may fall outside the range if it has unusual conditions, such as a very steep slope, a badly damaged slab or a site that equipment cannot reach.

Use the range to decide whether a project is feasible and how much to set aside. Then use a site walk and a written scope to replace the range with a real number. If a quote lands far below the range, ask what has been left out. If it lands far above, ask what is driving it.

Measure the area, pick the surface, then multiply by the planning range to get a low and high figure. Add allowances for the things under and around the surface: demolition, grading, drainage, repairs and access. If you are replacing lawn, compare the whole picture, including water use, upkeep and your water provider's and HOA's rules. The Metropolitan Water District's SoCalWaterSmart program states that no synthetic turf is allowed, so rebates generally do not apply to artificial grass.

For public agencies, school districts and HOAs, a written scope that lists the same items from every bidder makes proposals comparable and easier to approve. Associations also need to keep reserve plans current, and Title 22, section 101238.2 requires cushioning under and around climbing equipment at licensed child care centers.

The most common mistake is budgeting only for the surface. Demolition, hauling, grading, drainage, repairs and access are often a large share of a project, and they are the items most likely to be missing from a low bid. The second mistake is comparing bids that do not cover the same work. A turf bid that includes a compacted base is not the same as one that lays turf over existing soil. A floor bid that includes grinding and moisture testing is not the same as one that skips them.

A third mistake is forgetting about approvals. HOA boards, school districts and public agencies have meeting calendars, and those calendars can shift installation dates. Finally, do not forget upkeep. Wood fiber costs less up front than rubber, and a natural lawn costs less than turf, but each has recurring costs that belong in a fair comparison.
