Approximately 21,50 kg/m² of GROUT 6 SFR for every centimetre of thickness to be implemented (approximately 2150 kg per cubic metre).

Use fields

Structural restoration and adjustments, recovery and anchoring of road, motorway, airport joints and critical area joints in general.

Preparation of supports

Application surfaces should be clean, free of soiling, crumbling and non-adhering parts, dust, etc., conveniently saturated with water until they reach the condition "saturated with dry surface".

Use method

Pour about 2/3 of the mixing water into the mixer, add GROUT 6 SFR and the remaining water; continue to mix until a homogeneous lump-free mixture is obtained. The mixing water should be about 13%-15% by weight (3.5-4.5 litres per bag). Adopt casting procedures capable of ensuring the absence of discontinuities and avoid the formation of air pockets.

For high anchoring sections it is appropriate to add GHIAIETTO 6.10 (please refer to the appropriate technical data sheet for more information).
