Modular Mini-Packer Systems (MMPS) are mainly used for hydrogeological characterisation of excavation damaged zones around a tunnel or along a shaft.

Features of the Modular Mini-Packer System (MMPS)

• for boreholes with 50 - 56 mm diameter
• up to 6 borehole sections
• the minimum interval length is 15 cm
• pressure measurement in all intervals
• flow lines for pneumatic or hydraulic permeability tests
