For basement uplift, base-slab cracking and beam or slab damage associated with rising groundwater or inadequate anti-flotation resistance, we coordinate investigation, assessment, design, construction and monitoring. Depending on the project, measures may combine anti-flotation anchors, tension piles, ballast and drainage or pressure relief. The approach addresses uplift deformation, structural safety, waterproofing and the continued operation of underground space.
The method and implementation conditions are determined through investigation, design and the project-specific engineering scheme.
What to establish before discussing a project
Describe the existing condition, the problem to be resolved, intended use and construction constraints. Drawings, investigation results and site information then inform the engineering approach. Scope, implementation conditions and deliverables are defined in the project agreement.
Information to prepare
- Ground investigation and groundwater records
- Basement structural drawings
- Crack, deformation and leakage records
Project pathway
