An ultra-high strength grout specially formulated using a Portland cement powder mix. The mix design consists of a blend of fine and ultra-fine cements, high quality graded sands and a set of synergistic admixtures. The mix design includes special shrinkage compensating components, which give a non-shrink grout in both the plastic and hardened states. Powerful plasticizing agents produce a highly flowing grout at low water content. The material readily mixes with water to produce the ultra-high strength grout that is easily placed to give exceptional structural support and vibration resistance.

Teknodure HS is chloride free and can be safely used in contact with reinforcing steel and structural steel elements. The specialized mix design enables placement at low water content leading to good freeze-thaw stability, low water absorption plus resistance to oil, sea water and mild alkali attack. The product exhibits highly anti-washout properties and is ideal for underwater applications.
