Basement Waterproofing

Basement seepage is the most common moisture complaint in Sewickley's older homes. Groundwater pressure from seasonal rains and snowmelt pushes through concrete cracks and porous walls.

We apply interior membrane liners and install sump pumps to redirect water away from living spaces. This protects finished basements and storage areas.

Exterior Waterproofing & Grading

The best waterproofing starts outside. Many Sewickley properties have poor grading or damaged exterior drainage, allowing water to pool near the foundation.

We regrade slopes, install French drains, and apply exterior membrane coatings to stop water before it reaches the foundation wall.

• Exterior grade adjustment and slope correction
• Perimeter French drain installation
• Exterior waterproof coatings and membranes

Foundation Repair & Stabilization

Cracks in basement walls or floors signal foundation stress. In Sewickley, settlement, freeze-thaw cycles, and water pressure all contribute to structural movement.

We repair cracks with injection methods, shore up bowing walls, and stabilize settling foundations to restore structural integrity.

• Wall bracing and bowing wall repair
