Webster Bros. Concrete

We’ve verified Webster Bros. Concrete has used the following mixes meeting our Stronger Standard.

Foundation Mix

3500 PSI @ 28 days; 4” Slump; .55 W/C

Reviews

Scott M. (developer) Pleased that it exceeded spec on the foundation.

  • A Fortified mix should always result in strength that exceeds the PSI specified by the engineer.

  • Traditional Portland cement requires significantly more energy and cost to manufacture than pozzolans. Therefore, cost savings are usually found when choosing low carbon concrete mixes, although premiums are possible depending on market supply & demand and admixtures.

  • To qualify as low carbon concrete on Fortify Fleet, a mix must rank within the top 25% percentile of mixes with the same PSI within a 25-mile radius, as listed in the University of Washington's EC3 nonprofit carbon accounting database.

  • Pozzolan, crucial for the durability of Roman concrete, is required for Fortify Fleet and involves materials like fly ash, slag, calcined clay, and more that react with calcium hydroxide. This reaction boosts impermeability, curbs ASR expansion, and strengthens concrete by filling pores and creating durability enhancing silicate and aluminate hydrates.

  • This complies with the local Santa Monica low carbon concrete code and the national General Service Administration (GSA) low carbon concrete code.

Pool Mix

4500 PSI @ 28 days; 2” Slump; .45 W/C

FAQs

  • We gather certain documents from the subcontractor in order to verify they have successfully used low carbon concrete mixes. Then an anonymized summary of the mix design is published for 5 categories: PSI, Cost, Carbon Footprint, Pozzolonic Reaction and Coast to Coast Code Compliance. 

  • Fortified™ subcontractors can help you build on-time and on-budget because we’ve verified they have a successful track record using novel, low carbon materials.

  • Fortified™ subcontractors can submit competitive bids because they use concrete mixes that replace expensive Portland cement with more affordable, strength-enhancing materials like pozzolans.

  • The cost is often equal to or less than conventional concrete. At bid submission, Fortify Fleet will verify there is no cost premium compared to conventional concrete and we will also verify that the mix complies with low-carbon requirements. We will provide you a summary of these results in our Mix Cost Verification Sheet.
