Project pipeline is the leading indicator
Pull the backlog and forward commitments. Concrete is project-based: a healthy contractor has 3–6 months of committed work in writing (signed contracts, accepted bids, or work orders) plus more work in the bidding phase. A company with zero backlog at sale isn't broken — concrete is seasonal in most markets and slow periods happen — but a long pattern of light backlog signals customer relationship problems. Verify backlog with copies of contracts and ask about the seller's win rate on bids.
