Do you have a building, a house or a garage to demolish? Avoid delays and entrust your project to us.
Are you seeing cracks in your concrete slab or heaving of the floor? Gesco Construction carries out careful excavation of the material under existing slabs in order to remove pyrite, replace contaminated or inadequate backfill, and prepare your ground for new structures.
Our specialized equipment and controlled techniques allow us to work efficiently inside your residential, commercial and industrial buildings while preserving the integrity of the overall structure.
Pyrite and swelling backfill removal: Complete extraction of the contaminated materials pressing on the structure.
Rebuilding under-slab plumbing: Clearing the ground to repair, replace or modernize the water and drainage lines.
Correcting a cracked or sunken slab: Replacement of the unstable granular base with compliant material (DB).
Ground preparation for renovations: Excavation required to lower a basement or install a new waterproofing system.
Excavation work under an existing slab calls for maximum precision. Our crews ensure rigorous dust control, protection of adjacent areas and efficient removal of the extracted material to authorized disposal centres.
