The expansion of the quarry is expected to have an influence on the water management in the area. We have investigated this with a pumping test and an impact study. It is decided to install an underground water retaining wall untill 15 meter deep to prevent the influence on the environment. For this a Mixed-in-Place wall (MIP wall) will be installed.

Wiertsema & Partners will guide the contractor with the installation of the MIP wall. We will install inclinometer tubes in the wall. With these any future deformations can be determined. The activities also include sampling and testing of the MIP material to determine the characteristic parameters. Furthermore we will monitor the groundwater as part of determining the influence of the wall on the environment.
