Drilling & Plugging Method Explained

This method can be applied to the cracks that appear in straight lines. A hole is drilled near the crack and filled with grout in this method. This grout forms the key to lock the crack, preventing further propagation. The grout precludes leakages and loss of soil. This is why this method is cost-effective and consumes less time.

Another way to close the drilled hole is to fill the drilled with an epoxy mortar or epoxy formulation with reinforcing bars. The rods used have lengths and sizes, so they sew across the crack.

In this procedure, a hole diameter of 50-75 mm is drilled. It Depends on the width of the crack after the crack location. The hole should be large enough to cut the entire length of the crack and provide sufficient repair material to accommodate the structural load on the key. Assume that water tightness is an essential requirement for structural load transfer. In this case, the drilled hole can be filled with a low modulus elastic material. If both properties are required, the first hole is filled with mortar, and the second hole is filled with flexible material.
