Conbextra GP is a general purpose shrinkage compensated (Class A) cementitious, flowable or trowellable grout for gap thicknesses from 10 mm up to 100 mm. Conbextra GP has a 28 day compressive strength of 65 MPa when mixed at trowellable consistency.
Typical Applications
- General site grouting where higher compressive strength is required
Advantages
- High ultimate strength and low permeability ensure the durability of the hardened grout
- Gaseous expansion system compensates for shrinkage and settlement in the plastic state
- Can be dry packed, rammed, trowelled, poured and pumped
- Pre-packaged material overcomes potential on-site mixing variations
- Develops high early strength without the use of chlorides
- No metallic iron content to cause staining
- Complies to AS/NZS 4020:2005 Products in Contact with Potable Water
