This consists of soil mix walls. Soil mix is a vibration-free deep foundation technique that utilizes the existing soil as a raw material for creating the deep foundation elements. Ultimately, this forms a closed, continuous, and water-resistant layer up to 16 meters below ground level.   <\/p><p>To achieve this, a Report of Subdivision was first realized for OVAM to carry out the works. For this purpose, an on-site measurement was performed, and research was conducted into the history of the parcel boundaries, among other things. <\/p><p>Once this was achieved, the staking out of the soil mix walls could begin.<\/p><p>These were staked out in various phases with a fixed offset as agreed upon with the site manager.<\/p><p>Using RTK drones, the contractor performed a complete drone survey which was verified using traditional methods for confirmation and, naturally, was found to be accurate.<\/p><p>Once the containment was completed, we were commissioned by OVAM to capture it using a suitable drone.<\/p><p>In the coming weeks, we plan to stake out the remaining soil mix walls for the execution of the next phase.<\/p><h2>Questions about our services?<\/h2><p>info@topo4d.be
