Rheomac 730 

Rheomac 730 is a hydrophobic pore-blocking ingredient (H.P.I) for concrete.  It significantly reduces the water absorption of concrete.

Rheomac 730 is a chloride free organic admixture and is supplied as a brown liquid.  It reacts with the cement hydration process to form a hydrophobic ingredient to reduce capillary suction and prevent the ingress of potentially deleterious soluble material, resulting in concrete with enhanced durability.

Rheomac 730 is suitable for any concrete structure, which requires watertightness, such as:

• basement walls and floors
• tunnels / underpasses
• foundations, piles and pile caps
• water retaining structures, swimming pools, water tanks, reservoirs, water towers
• land drainage, manholes
• reinforced concrete in a marine environment subject to tidal and wet/dry cycles
• waste water treatment and desalination plant
