Uses

Conbextra HES is used for free flow grouting in a wide range of applications where rapid strength gain is a prerequisite.

Description

Conbextra HES, rapid set high strength cementitious precision grout, is supplied as a ready to use powder. The

addition of a controlled amount of clean water produces a free-flowing grout for gap thicknesses of 15 – 150 mm. In addition the low water requirement ensures high early strength and long term durability. Conbextra HES is a blend of cements, graded aggregates and additives which impart controlled expansion in hardened state. The aggregate grading minimises segregation and bleeding over a wide range of application consistencies.

Maximum aggregate size is 5.0 mm.
