Excavation is completed in controlled phases to maintain soil pressure balance and foundation stability.
We specialize in:
Underpinning extends your existing foundation deeper to create full ceiling height while preserving maximum interior space.
Benefits:
• Full usable floor space
• Increased property value
• Stronger foundation
• Legal basement apartment potential
Work is performed section-by-section to ensure structural safety.
Bench foundation lowers the basement floor without extending the original footing.
A reinforced concrete bench is built along the perimeter to support soil pressure.
Benching is ideal when:
• Budget is a priority
• Slight reduction in floor space is acceptable
• Structural conditions allow
