Novax pre-stressing grout is a pre-bagged cementitious material used in conjunction with weeping bag systems for the pre-stressing of underground mine support packs.
- Novax provides immediate support between the underground mine support pack and the hanging wall.
- Novax accommodates uneven hanging wall profiles.
- Novax allows immediate dewatering of the pre-stressing system, thereby improving non-shrinkage characteristics.
- Novax is simple to mix, pump and place.

Materials should normally be stored under cover. Reduced shelf life may occur if packaging is exposed to the elements. Packaging materials may deteriorate, allowing moisture ingress into the cementitious binder. This could lead to premature hardening.
Novax products will store for up to 6 months in dry conditions.
