Timeline depends on repair extent. Simple drainage improvements take 2-3 days. Shotcrete applications for spalling repairs take 3-5 days. Major structural stabilization with ground anchors or soil nails may take 2-4 weeks. We provide detailed schedules after initial structural assessment and geotechnical review.

Yes, properly executed shoring wall repairs are permanent. Shotcrete applications bond permanently to existing concrete. Ground anchors and soil nails provide permanent load transfer to stable soil. We provide 5-10 year warranties depending on repair extent and ongoing maintenance requirements.

Common failure causes include drainage failure (water pressure buildup), reinforcement corrosion weakening load capacity, inadequate anchor maintenance, soil movement from adjacent excavation, and aging concrete deterioration. We conduct geotechnical assessment including soil testing and drainage analysis to identify root causes before designing repairs.

Costs vary significantly. Simple drainage upgrades cost $3,000-8,000. Shotcrete repair of 50 sqm spalling costs $8,000-15,000. Major structural repairs with new anchors or soil nails range $30,000-100,000 depending on wall height and soil conditions. Geotechnical assessment required for accurate quoting.

Minor drainage repairs and shotcrete patching allow normal property use with temporary fencing for safety. Major anchor or soil nail installation typically requires restricted access to the work area but doesn't necessitate full property evacuation. We minimize disruption through careful work sequencing and scheduling.

Yes, we recommend geotechnical assessment for all shoring wall repairs exceeding simple maintenance. Assessment identifies underlying soil conditions, bearing capacity, drainage patterns, and appropriate repair methods. Certified geotechnical reports are required for major repairs and ensure long-term stability.
