What Our Concrete Partners Say

“From what we saw in the field, it handled really well. It was easier to finish, had a noticeably brighter color, and didn’t disrupt our normal operations. What stood out most was the Fortera team, they know their material, and their guidance on mixing and placement made the whole process smooth.”

Elijah MosleySuperintendent at South Bay Construction

“Fortera’s ReAct performed really great, it goes almost unnoticed once mixed. The product proved to be practitioner friendly, easy homogeneous finish and great strength results.”

Dr. Somayeh NassiriAssociate Professor in Civil & Environmental Engineering at UC Davis

“The footing concrete poured just like our traditional mix designs. For slab-on-grade, placement and finishing were very similar to mixes containing fly ash. Saw cut control joints held an edge better than typical fly ash mixes, and we’ve observed no abnormal cracking to date.”

Brian KamiskyPresident of SK Construction / Wards Concrete

“It was great working on the Simpson University project with the crew from Fortera and I look forward to the next project. With concrete being the most widely used construction material in the world, I believe Fortera is moving our industry in the right direction.”

Shawn SteeleShasta Redi Mix Manager of J.F. Shea Construction, Inc.

“The concrete with ReAct finished more easily. There was noticeably less cracking in the mix with Fortera compared to without. The consistency in color and surface would make me excited to use ReAct in decorative or architectural concrete.”

Luis MaciasOwner of LCM Concrete Construction Company

“In my experience I can say that the concrete mix with ReAct material cleared out 200 linear feet of hose without delay, as with regular concrete mix there is an 80% chance we have an issue … NO DRY PACK as a pump operator this makes our job a lot easier. The product looks amazing when it’s all finished and cured.”

Alfredo CisnerosOwner of Freddy’s Concrete Pumping

“The 56-day results from the UC Berkeley Substation #8 are impressive and speak to the strength of Fortera’s ReAct product. It performed as promised, and we’re encouraged by what this
means for future applications.”

David BischoffSenior Project Manager of Webcor Concrete Group

“The fresh-state properties of the concrete containing 12% Fortera ReAct Blend demonstrated impressive workability, was easy to both place and finish and performed very well at the Berkeley Substation 8 Project. It looks excellent in its hardened, finished state too, having a very light albedo.”
