Wetcrete

Wetcrete is a pre-bagged wet shotcrete mix for use in underground support, or in structural repair situations.

 

Advantages

  • Wetcrete is available with fibre-reinforced or non-reinforced types and provides excellent pumping characteristics.
  • Wetcrete drastically reduces dust production. No dust produced at the nozzle.
  • Wetcrete can be used with a range of chemical admixtures to modify the shotcrete application quantities without adversely affecting the final support material.
  • Wetcrete can be transported, mixed and placed using conventional or specialised equipment.

Packaging

Outer bag Inner bag
Virgin, woven, pre-printed, polypropylene bag, with stitched polyester seams. Colour coded for easy identification of product. Virgin, low density, polyethylene bag with heat-sealed sides and bottom seams.

 

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
Wetcrete products 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.
