BETEC 322 HOZ
| Description |
|---|
BETEC 322 HOZ is a synthetic modified and strengthened by synthetic fibre repair mortar based on blastfurnace cement. This mortar is also highly suited for manually performed repairs (pcc) as well as for the wet-guniting system. 322 HOZ is aprooved for using in drinkingwaterinstallations see test. Betec 322 HOZ is authorised for drinkwater installations |
