When large trenches are dug in construction sites, it is imperative that the walls of the trench itself do not collapse and close the work site. Bentonite is a mixture of clay and water that due to its physical properties creates a support layer for these trenches avoiding their collapse.

Bentonite is pumped into the trenches to keep the walls firm but as it mixes with the soil, it loses its physical properties and its ability to support the walls.

It is then necessary to keep the bentonite clean and circulating into the trench. The used bentonite is pumped out using one a Dragflow pumps pump into a filter that then returns the clean bentonite into the shaft, providing the required support to the walls.
