• Climate Change

Climate Goals & Targets

Environmental Challenges

• Subsidence/heave in shrinkable cohesive soils (shrink–swell) due to changing weather patterns and increased tree/canopy cover.
• Washout-induced damage or settlement due to increased frequency and intensity of storms with high rainfall events.
• Dissolution and anthropogenic hazards in chalk/limestone and evaporites due to increased rainfall.
• Collapse settlements in earthworks and fills due to inundation.
• Reduction in soil strength associated with increases in porewater pressure due to heavy rainfall.

Mitigation Strategies

• Designing foundations for new domestic structures to accommodate climate change resilience (deeper foundations, mini-piles, ground beam foundations).
• Hydraulic modelling of drainage systems and watercourses to accommodate projected flash flood events.
• Comprehensive investigation of sites vulnerable to dissolution or historic workings to inform design and construction.
• Preloading, dynamic compaction, or vibro-compaction to stabilize fills.
• Installing internal drainage systems to remove porewater from fine soils and prevent loss of stability.

Climate-Related Risks & Opportunities

Physical Risks

• Extreme weather patterns (hotter, drier summers; warmer, wetter winters); higher sea levels; increased frequency and intensity of storms.

Opportunities

• Development of innovative foundation designs and construction practices to increase climate resilience.
