Tstrata ISR™
Tstrata ISR™ is a specially formulated, one-part microsilica-modified restoration material with integral corrosion inhibitor designed specifically for the 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.
