MasterInject 222 is a premixed, cement-free, pozzolanic lime grout with a very fine grain size (less than 12 μm), with high fluidity and excellent maintenance of workability.
It is also expansive in the plastic phase, to ensure that even the smallest gaps are filled. It guarantees a compressive strength> 10 MPa and is therefore classifiable as an M10 type masonry mortar according to the European standard UNI EN 998/2.
BENEFITS:
- Cement free
- Can be used in environments under sulphate attacks
- It doesn’t react with original building materials either physically, nor chemically
- The superior hydraulic nature of the binder enables the injection mortar to penetrate into the building deeply
- With the assistance of the medium elasticity modulus, it is ideal in the filling of small and large voids even in bearing problems due to the high moisture content of the original building material
- Does not affect the vapour and moisture permeability of the existing building
- It shows limited expansion that does not cause any additional internal stresses in the masonry elements
- Does not bleed
- Easy to inject even under low pressures
- Water-born salts (alkalis, sulphates, chlorides or nitrates), are limited
