Tstrata ISR Sulfate Resistant Concrete

Tstrata ISR™ – Infuseable Sulfate Resistant Restoration Material

Tstrata ISR™ is a specially formulated, one part microsilica modified restoration material with integral corrosion inhibitor designed specifically for restoration of sulfur pits. It is a premixed, dry packaged concrete material that contains pea gravel suitable for interior and exterior “form and pour” and “form and pump” installation. Requiring only the addition of water – Tstrata ISR™ is a high strength material with extended working time for ease of placement. It is handled like ordinary high slump concrete.

  • Excellent sulfate resistance
  • Microsilica modified for high strength
