Well reinforcement

Unstable borehole walls or damaged casing may require a reinforcement solution adapted to the ground.

Soft ground, swelling clay or changing groundwater levels can cause movement around older wells and threaten their casing. Reinforcement is planned to stabilise the borehole walls and protect the existing well structure.

Where the assessment and design call for it, reinforcing elements or piles around the borehole can take ground loads and limit deformation. The solution is sized for the specific soil, depth and condition of the well, aiming to keep the intervention limited while providing lasting structural support.

• Borehole-wall reinforcement
• Solutions adapted to weak ground
• Protection of existing casing
• Dimensions selected for each project
• Limited intervention with planned structural support
