Fosroc Conbextra Gp2 Non Shrink Grouting Powder
Conbextra GP2
page 1 of 4
Free fl ow, high strength, non-shrink,
cementitious precision grout
Uses
Conbextra GP2 is used for precision grouting where it is essential
to withstand static and dynamic loads. Typical applications would
be the grouting of base plates of turbines, compressors, boiler
feed pumps etc., It can also be used for anchoring a wide range
of fi xings. These include masts, anchor bolts and fence posts.
Advantages
Gaseous expansion system compensates for shrinkage
and settlement in the plastic state
No metallic iron content to cause staining
Pre-packed material overcomes onsite batching variations
Develops high early strength without the use of chlorides
High ultimate strength ensure the durability of the hardened
grout
Free fl ow ensures high level of contact with load bearing
area
Description
Conbextra GP2 is supplied as a ready to use dry powder. The
addition of a controlled amount of clean water produces a free
fl owing, non-shrink grout for gap thicknesses up to 100mm.
Conbextra GP2 is a blend of Portland cement, graded fi llers
and chemical additives which impart controlled expansion in the
plastic state whilst minimising water demand. The low water
demand ensures high early strength. The graded fi llers are
designed to assist uniform mixing and produce a consistent
grout.
