Our Product

Our POWERSET™

Our product of conventional or Alkali Free Shotcrete Accelerant can be used in both dense and thin flow processes for wet spray or dry sprayed concrete. Our POWERSET™ Shotcrete Accelerant are designed to achieve your desired concrete early strength development for construction needs.

Our POWERSET™ Product Benefit:

  • Provide excellent shotcrete early strength
  • Alkaline free, thus providing better early strength results and low toxicity to tunneling operators
  • Available in liquid form & powder form
  • Compatible with any retarders & superplasticizers formulations

POWERPLAST™

Our various chemicals for superplasticizers, from Naphthalene, Melamine, to Polycarboxylate chemistry, are designed to help your sprayed concrete achieve a desired workability and consistency for easier use in your sprayed concrete application.

Our POWERPLAST™ Product Benefit:

  • Compatible with various shotcrete accelerant formulations
  • Provide very low water content in the final set concrete sprayed
  • Lowers water requirement for hydration

POWERTARD™

Our Retarder admixtures can be used in the batching plant before the concrete is delivered to the construction site. It allows the setting time to be delayed and preserve both consistency and workability.

Our POWERTARD™ Product Benefit:

  • Provide flexibility for longer duration of retardation
  • Excellent workability for shotcrete application
  • Compatible with various shotcrete accelerant formulations

POWERFLOC™

Our Polymer solutions are designed to help smoothen the slurry removal and water circulation processes in Tunnel Boring Machine activities.

Our POWERFLOC™ Product Benefit:

  • Provide faster settling rate for sediment removal
  • Provide faster recirculation of cutting removal
