Castable cement micromortar, for paving in natural stone

Code: GRT.0252

Components: 1

Appearance: Powder

An anti-shrinkage, pourable, self-levelling, super-adhesive micro-mortar, based on high-strength cements, super-pozzolanic fillers, polymeric stabilisers and anti-shrinkage agents. Aggregates with a maximum size of 0.35 mm. Ideal for filling joints (gaps and/or interstices) in urban paving made of porphyry or stone slabs, even of large dimensions. For filling cracks and lesions on concrete and masonry structures.

GROUT FILL achieves fluid and hyperfluid workability even with very low water / cement ratios (<0.4), thus resulting perfectly homogeneous, pourable, self-leveling and without water exudation phenomena. The very fine granulometry of the aggregates allows the perfect filling of spaces and particularly narrow discontinuities (<0.5 cm). The capillary absorption of the applied micro-mortar is very low, allowing great resistance to freeze-thaw cycles and washout. GROUT FILL achieves extremely high mechanical performance and is rich in microsilicates with pozzolanic activity and special additives that make it extremely durable even if positioned in particularly aggressive environments (due to contamination by chlorides, sulphates, marine atmospheres, fuels and automotive oils).


Approximately 1800 kg of GROUT FILL for each cubic metre of volume to be filled.

Use fields

Filling the joints (vanishing points) in urban floorings in porphyry, stone slabs etc., in new installations and in the reinforcement of existing installations. Anchorages and rigid seals in general.

Preparation of supports

Remove the soilings, the crumbling and non-adhering parts and saturate beforehand with water.

Use method

Pour about 2/3 of the required mixture water in the mixer (about 3.5 -4 litres total per bag); gradually add the product and the water still required to get the desired consistency. Continue mixing until you obtain a homogeneous, lump-free mortar. Pour the compound thus obtained in the vanishing points to be filled.

Application methods

- Pour out

Tool cleaning

- Water

Permitted supports

- Asphalt

- Concrete

- Floor screed

- Porphyry and natural stones

Warnings, precautions and Ecology

Do not apply in the presence of stagnant water and direct solar irradiation, in anticipation of atmospheric precipitation and/or sudden drops in temperature.

Treat the hardening and the damp protection fresh mortar placed on site .
