The most common and secure way to attach a bottom plate to a concrete slab is with concrete screws or a powder-actuated nailer. If drilling is truly not an option, a high-strength polyurethane construction adhesive can be used for *non-load-bearing* walls, but this is less common and offers less stability. The bigger issue here is often building code compliance; many jurisdictions require mechanical fasteners for structural integrity and seismic resistance. Skipping these could lead to an unsafe structure or require costly rework. Always check with your local building department first.

Once the water source is fixed, the affected drywall and insulation must be removed, the cavity dried, and any mold treated before reinsulating and replacing. This investigation and repair often needs a licensed plumber, roofer, or a foundation specialist, followed by a general contractor for proper remediation and rebuild.
