A Stronger Standard
You can trust that when vetting subcontractors, we go above and beyond.
Our Standards
To meet Fortify Fleet’s standard, a subcontractor must submit a previously used concrete mix that:
Exceeded the engineer’s specified strengths when fully cured
Had a carbon footprint in the lowest 25th percentile
Included a pozzolanic material
Complied with the nearest low-carbon concrete code
Costs equal to or less than conventional concrete
We also prioritize companies that use USA-sourced and manufactured pozzolanic materials, ensuring sustainable and high-quality solutions. We’ll review mix designs, laboratory compression reports, quotes and building codes to verify suboncontractors have had successful experience using pozzolan-enhanced concrete before we list them on Fortify Fleet.
