Micropiles

Micropiles are structural elements used in foundations to transfer loads from a superstructure to the underlying soil. They have a smaller diameter than traditional piles, typically between 100 and 400 millimeters, and are particularly useful in situations with limited access or difficult soil conditions.

Micropile Structure

Steel Tube or Reinforcement: Provides tensile and compressive strength.
Grout or Concrete: Fills the hole and surrounds the reinforcement, adding strength and protection against corrosion.
Cement Injection: Often injected at high pressure to enhance adhesion between the micropile and surrounding soil.

Main Types

Foundation Micropiles: Transfer loads to deeper, more stable soil, improving foundation stability.
Soil Stabilization: Used to stabilize soil in areas prone to movement, such as landslides or settlements.
Existing Foundation Consolidation: Reinforce existing foundations showing signs of settlement or needing upgrades for new loads.

Applications

Residential and Commercial Construction: For new buildings or strengthening existing foundations.
Civil and Infrastructure Projects: Applied in bridges, roads, and railways to improve structural stability.
Slope and Embankment Stabilization: Prevent landslides and stabilize unstable soils.
Restoration and Consolidation Projects: Enhance the stability of historic buildings or structures needing reinforcement.

Advantages of Micropiles

Versatility: Installable in confined spaces and hard-to-reach areas.
Adaptability: Usable in various geotechnical and environmental conditions.
Minimal Invasiveness: Installation technique minimizes impact on existing structures and surrounding soil.
Effectiveness: Provides high load-bearing capacity and improves foundation stability with relatively quick interventions.
