Novax
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.

Advantages 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.

Packaging Outer bag: Virgin, woven, pre-printed, polypropylene bag, with stitched polyester seams. Colour coded for easy identification of product. Storage 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. Shelf Life Novax will store for up to 6 months in dry conditions. Safety

General	The use of eye protection, gloves and dust masks is recommended. Follow the typical precautions as prescribed for handling Portland cement.
Inhalation	Constant exposure over long periods of time to very high concentrations may cause a cough with phlegm.
Skin contact	Prolonged exposure could sensitize skin causing mild irritation. In extreme cases, dermatitis could occur.
Eyes	Use eye protection. However, if eyes become affected, irrigate eyes with copious amounts of clean water. Seek medical attention.
Ingestion	Ingestion of harmful quantities is unlikely to occur. If ingested, drink copious amounts of drinking water and consult a medical practitioner. DO NOT INDUCE VOMITING.
