BETEC 343 / 343 SF
| Description |
|---|
BETEC 343/343SF are non- (wet) shrinking repair-drypack mortars of the RAPID type based on Portland cement with microsilica which are applied for constructive repairs and drypack (grouting) manholes edges. For applications that need very shortly high compressive strengts and to undergo high temperatures (for example asphalting), these products can also be delivered with stainless-steel fibres industrially mixed in. |
