An innovative new product by Gresser Co. — the world’s first jointless concrete – was recently implemented at the recently-completed 43,000 s.f. MicroSource fertilizer warehouse project in Shakopee, MN.

Strong, Durable and Economical PrīmXComposite

Known as PrīmXComposite, the product provides concrete floors that are strong and durable as well as virtually crack free. The strong concrete allows for thinner floor designs with reduced life cycle costs, making it economical to construct and maintain. Its qualities make the product ideal for a number of applications, including warehouses, retail stores, industrial factories and manufacturing facilities.

“The big advantage is no rebar,” said KA project manager Doug Jaeger. “It uses steel fiber instead and absorbent mats under the cement pour. The concrete swells as it cures instead of shrinking.”

Jointless Concrete Advantages MicroSource fertilizer warehouse

The steel fiber-reinforced, non-shrink concrete flooring system eliminates the joints in concrete, and consequently, post-installation issues.

Jointless floor systems provide multiple benefits, including:

  • No joints in concrete on daily pours
  • Superior for robotic driverless forklifts with no disturbance
  • Increased productivity (no slow moving)
  • No detrimental effect of shrinkage, curling is eliminated
  • Reduced long-term floor maintenance costs
  • No requirements to fill or maintain saw-cut joints

The new product also elevates the sustainability of concrete, which is responsible for 5 percent of global CO2 emissions. PrīmXComposite is up to 30% thinner than traditional concrete floors and produces up to 50 percent less CO2 than normal. The jointless process also eliminates silica dust, which is created from saw cutting.

“We are coming up on a year of hard use of our new warehouse,” said Kipp Smallwood, general manager/COO of MicroSource.  “The floor is 100% crack free and has exceeded our expectations! One more benefit is the shine it gives off. It looks like it would be slippery but it’s not. I think this system will revolutionize concrete floors as it becomes more widely understood,” Smallwood said.
