Grout flow meter is necessary for grouting work at various construction sites, especially at foundation work, to guarantee precise construction work and to prevent a shoddy and fault job. It records the status of work and construcyion data in graph and letter each on the recording paper and so no need to calculate injection volume and depth separately.

1) Necessary fields

- Foundation reinforcement and underground water control for civil work and building construction.

- Grouting works gor tunnel, dam and reservoir.

- Foundation reinforcement and water block for subterranean line

- Foundation reinforcement for subway and railroad construction

- Reinforcement of rear side of earth retaining wall.

- Earth anchor installation.

- Stabilization of structure foundation.

2) Reasons to use

- precise construction management. (preven fraudulent work)

- Recored exact flow and pressure. (Secure technical data for design & construction)

- Quality management through reliable work.
