Where to use
SLURRY SHIELDS
Mapedrill Bio L is a high viscosity product; it can effectively replace bentonite, thus enabling the preparation of fluids with no solids content.
Fluids prepared with Mapedrill Bio L have a high lubricating and cooling effect and can be used even in highly contaminated grounds. Mapedrill Bio L has a lubricating effect for mechanized tunnelling, significantly reducing torque (especially in presence of fine particles) and enhancing TBM performance.

EPB
The use of Mapedrill Bio L gives more stability to the foam produced with foaming agents, also inhibiting clay swelling.
Mapedrill Bio L acts on the foam bubbles, gluing them together, improving foam density before, and during, the injection. Moreover, during mucking operations, Mapedrill Bio L improves the stability of the spoil, inhibiting the settling of excavated solids.
Mapedrill Bio L lubricates the EPBM, reducing torque, cutter wear and accelerating process.
Mapedrill Bio L, due to its formulation and as well the liquid form, do not require any specific mixing equipment (such as high shear mixer).

Consumption
A slurry for Hydroshield: from 0.2 to 2.0%.
As foaming stabilizer from 0.3 to 1%.
As polymer for brattice stabilizing mud from 0.2 to 2.0 kg/m3.
Our technical laboratory is at the customer complete disposal for optimising the right Mapedrill Bio L dosage according to the drilling soil characteristics. Please contact our “Underground Technology Team” technical service for assistance in product optimisation.

Packaging
Mapedrill Bio L is available in 25 kg plastic kegs, 200 kg plastic drums, 1000 kg plastic mega drum.
