High performance liquid dispersing agent for tunnelling and drilling
Where to use Mapedisp FL is specifically formulated for generating an immediate dispersing effect, preventing the clays or bentonite aggregation due to mineral electrostatic charges. Mapedisp FL is applied in the tunnelling field after mixing with water: it is advised to let the solution in contact with the ground for 6-8 hours.
Dosage Dosages depend either on the application field and/or on the round water consolidation degree. Drilling: 0.1-0.6% in water. Mechanized tunnelling: 5-10 kg per m3 of conditioning ground. Injection mixes: 0.-0.8 % in weight on the weight of cement. Our laboratory is available for assessing the dosage of Mapedrill FL with the soil types met during tunnelling. To make the best use of Mapedrill FL it is recommended to contact our “Underground Technology Team” technical service to verify and improve the characteristics, according to the local application conditions.
