Grouting Pump Application

In general terms, the definition of grouting is: an injection under pressure of fluid material into fractures and cavities in rock, soil or artificial structures.

Grouting in construction basically has three different main purposes: stabilization, strengthening, sealing.

Stabilization grouting is making a skeleton of grout in weak parts or areas of the ground and to avoid sliding in cracks, fissures or bedding planes. It can also be done as spot grouting at selected location.

Strengthening grouting is when the grouted ground is connected together by the grout and acts as one body. Joins, fissures, shear faults and other voids in the rock are filled with grout.

Sealing is strengthening grouting developed to almost water tightness, when a tunnel is dry or the seepage underneath a dam negligible.
