PrimXCompositeJointless. Stronger. Thinner.

Steel-Fiber Reinforced, No-Shrink Concrete Floors with No Saw Cuts

The first jointless concrete floor with no saw cuts, PrimXComposite is a steel fiber-reinforced, no-shrink concrete flooring system. PrimXComposite contains steel fibers and two types of add mixtures combined with ready-mix concrete to create a composite material. It requires no joints or saw cuts within each pour, eliminating a mile or more of joints per typical large-scale placement.

Concrete Reality

Advancements in composite materials, such as carbon fiber, plastics and polymers create thinner materials with increased strength and performance. While other materials have been improved, concrete has been virtually unchanged since the early 1820s. Traditional concrete:

  • Is strong in compression, but weak in tension
  • Is considered a quasi-brittle material, like ceramic (china)
  • Needs to be cut in anticipation of cracks, sawing joints every 12 to 16 feet (3.64 to 4.87 meters)
  • Requires steel rebar for reinforcement
  • Curls at joints, causing deterioration and reducing productivity
  • Requires regular maintenance and high repair costs
Traditional Concrete

Traditional Concrete: Curling at saw cuts and joint damage.

PrimXComposite Concrete

PrimXComposite: Jointless, stronger and thinner, doesn't curl.

The PrimXComposite Difference

During wet cure, the PrimXComposite system absorbs water, causing a delayed chemical reaction. The additives in PrimXComposite form a micro-scale composite structure, including crystals, that expand and compress the internal concrete matrix. This expansion puts the steel fibers in tension creating a permanent pre-stress compression. The patented application allows for the dramatic thinning of slabs from traditional design.

PrimXComposite Structure

PrimXComposite Floors

  • Are engineered to exceed design load requirements
  • Increase material handling productivity
  • Reduce equipment maintenance costs
  • Allow storage racks to be placed and moved anywhere needed
  • Are virtually maintenance free
  • Have a significantly longer life cycle

PrimXComposite is eligible to earn LEED credit and has many sustainability benefits. It uses less material, eliminates hazardous silica dust from joint sawing, and reduces carbon dioxide emissions by reducing cement content.

Trusted by the most sophisticated companies worldwide, over 60 million square feet of PrimXComposite is in service today. PrimXComposite is the most stable and advanced concrete flooring product on earth.
