🚧 Muddy Water: The First Warning Sign of Ground Loss & Increases Subsidance Risk ⬆️ 👉 One Major Risk during hydraulic drilling for bored piles, secant piles, diaphragm walls or micropiles for either slope stabilisation, cutoff walls or ground support works is GROUND SUBSIDENCE CAUSED BY GROUND LOSS. The ground detoriates instead of improving. The process is #️⃣As borings creates a vertical cavity, groundwater in permeable soils or jointed rock may flow into this newly created low-resistance zone. #️⃣When the flow carry fines, a piping mechanism can develop and progressively extend with time. #️⃣The loss of fines increases permeability, and allows even more groundwater flow into the cavity #️⃣The ground is weakened and can subside even with a low trigger not than assumed by the designer based on investigation date and lab test.
