Foundation Settlement

Foundation settlement can cause structural damage and compromise the safety of the building.

Lateral Soil Movement

Lateral soil movement can exert pressure on the foundation walls, leading to bowing or tilting.

Hydrostatic Pressure

Excessive hydrostatic pressure from waterlogged soil can exert upward force on the foundation.

Weak Soil Conditions

Weak or unstable soil beneath the foundation can compromise its load-bearing capacity.

Underpinning Problem Solutions

Foundation Settlement Solution

Utilize underpinning techniques like helical piers or micro-piles to stabilize and support the foundation, preventing further settlement and ensuring structural integrity.

Lateral Soil Movement Solution

Implement underpinning methods such as tieback anchors or soil nails to counteract lateral forces and reinforce the foundation against movement.

Hydrostatic Pressure Solution

Install drainage systems, such as French drains or waterproof membranes, along with underpinning to alleviate hydrostatic pressure and protect the foundation from water damage.

Weak Soil Conditions Solution

Strengthen the foundation with underpinning techniques like jet grouting or compaction grouting to improve soil stability and support the structure effectively.
