7. OPTEK HBT OPT-TEK HB-T is a high build thixotropic synthetic fibre reinforced cement based rheoplastic and non-segregating high strength mortar. OPT-TEK HB-T is a chemical resistant compound with Migrating Corrosion Inhibitor designed to protect embedded steel reinforcement and repair damaged or spalling concrete surfaces. USES OPT-TEK HB-T is used for the structural repair of concrete including: Water treatment and sewage facilities Marine structures Bridges Tunnels pipes outfalls and all below ground structures especially in harsh ground conditions Walls, cooling towers chimneys and other concrete repair applications

8. HBT Benefits BENEFITS Can be applied 5mm-50mm in a single layer thickness even in an overhead application Overhead, vertical and horizontal applicable in enclosed or open environments, wet or dry conditions. Excellent workability Sulphate resistance Shrinkage compensated High early and ultimate strengths Waterproof, highly impermeable Sprayable No added chlorides Excellent abrasion resistance and durability High Freeze/thaw, carbonation and sulphate resistance. Product, when correctly applied, has a life greater than 10 years

9. OPTEK PLUG Opt-Tek Plug is a one-component, rapid hardening plug composition for permanent stopping of water seepage and pressure leaks through cracks and construction joints in concrete, rock, wooden and masonry structures Opt-Tek Plug is a chloride free, ready for use grey powder based on Portland cement with special additives.

10. OPTEK PLUG USES Opt-Tek Plug can be applied to vertical, horizontal and overhead applications: static cracks and holes water storage tanks basements building foundations retaining walls sewers below ground car parks mines anchoring vertical bolts

11. OPTEK PLUG Benefits mixed just with water or can be used as a dry powder stop water flow fast setting with rapid strength development permanent durable repair can be installed underwater high water-stopping power and hydraulic resistance good adhesion to repaired material non-toxic easy application

12. OPTEK RF OPTEK R-F is a unique brushable penetrative fine cementitious coating specially designed for waterproofing and protection of old and new concrete against positive and negative water pressure. OPTEK R-F prevents the penetration of water and other liquids into the concrete by causing reactions that produce non-soluble cementitious formations within the pores and capillaries of concrete. These formations grow in the presence of water, blocking pores, capillaries and minor shrinkage cracks, thus waterproofing concrete. OPTEK R-F contains a Migrating Corrosion Inhibitor which significantly increases the corrosion protection of steel reinforcement in concrete.

13. OPTEK RF USES Concrete water towers and reservoirs Water treatment and sewage plants Swimming pools Roof decks Underground tunnels Basements and foundations Chemical and fertilizer plants Bridge pylons, beams and decks Marine structures Below ground car parks

14. OPTEK RF BENEFITS When correctly applied as a coating OPTEKR-F: Forms an indivisible body with the base concrete Significantly increases impermeability of concrete Resists extreme hydrostatic pressure from either positive or negative surface of the concrete slab Can be applied to the positive and negative side of the concrete surface Can seal hairline cracks up to 0.5 mm Enhances the properties of concrete against reinforcement corrosion Significantly reduces chloride penetration Allows concrete to breath Does not require a dry surface Has a life greater than 10 years.
