Crushed Concrete Base Quote Checklist
Compare crushed concrete base quotes by recycled material type, depth, compaction, drainage, contamination risk, delivery, cleanup, and exclusions.
A crushed concrete base quote should define recycled material type, gradation, delivery, depth, compaction, drainage, contamination risk, geotextile if needed, cleanup, warranty, and exclusions before it is placed under concrete.
Use this checklist before reviewing base-prep bids in the Concrete Quote Reviewer. Contractors can turn the accepted recycled-base scope into line items with the Concrete Proposal Kit.
Competitor pages such as ConcreteCalculatorMax's crushed concrete calculator and ConcreteCalculatorMax's gravel cost calculator show demand for recycled base math. The quote gap is material quality, compaction, drainage, and whether recycled material is appropriate for the job.
Quick answer
Compare crushed concrete base quotes with this structure:
crushed concrete base quote =
recycled material type, gradation, depth, delivery, placement, compaction
+ drainage, geotextile, contamination handling, cleanup, and exclusions
Recycled base suitability depends on project, soil, drainage, local rules, and material quality. Confirm use, compaction, and drainage with qualified local professionals.
Crushed concrete base inputs
| Input | Why it matters | What to ask |
|---|---|---|
| Material source | Recycled material quality varies. | Where does the crushed concrete come from? |
| Gradation | Fines, chunks, and size affect compaction. | What size or gradation is included? |
| Contamination | Debris, metal, asphalt, or soil can create issues. | Is the material screened? |
| Base depth | Depth changes tons and labor. | What compacted depth is included? |
| Compaction | Recycled base still needs proper compaction. | What equipment and lifts are included? |
| Drainage | Fines can affect water movement. | How is drainage handled? |
| Geotextile | Weak soil may need separation fabric. | Is fabric included or excluded? |
| Local rules | Some jobs restrict recycled material. | Is crushed concrete allowed for this scope? |
For ordinary stone base planning, compare this with the Gravel Base Contractor Quote Checklist. For disposal and recycling scope, review Concrete Disposal Fee.

Red flags in crushed concrete quotes
| Red flag | Follow-up question |
|---|---|
| No material source | Where does the recycled base come from? |
| No gradation | What size and fines content are included? |
| No contamination language | What happens if debris, metal, asphalt, or soil appears? |
| No compaction method | How is the base compacted and checked? |
| Recycled base substituted silently | Did all bids assume crushed concrete or stone? |
| No local approval note | Is this material allowed for this project? |
FAQ
What should a crushed concrete base quote include?
It should include material source, gradation, depth, delivery, placement, compaction, drainage, geotextile if needed, contamination handling, cleanup, warranty, and exclusions.
Is crushed concrete cheaper than gravel?
It can be, but compare full scope. Material quality, screening, compaction, delivery, drainage, and local acceptance can change the real cost.
Can crushed concrete be used under every slab?
No. Suitability depends on project requirements, soil, drainage, code, local rules, and material quality.
Should the quote mention contamination?
Yes. Recycled material can contain debris if not screened. Ask what happens if unsuitable material is delivered.
Is this engineering advice?
No. Confirm base design, material suitability, drainage, and local requirements with qualified local professionals.
