Regular inspection and maintenance of slopes and slope protection structures are essential in preventing damage to surrounding properties and injuries. Property owners are responsible for rectifying any slope defects upon detection.

Signs of slope defects

Property owners can identify slope defects when they see by looking out for the following:

When there are tell-tale signs of defects, property owners and management corporations must:

  • Engage a Professional Engineer (PE) in the civil, structural, or geotechnical discipline to inspect, assess and recommend rectification measures.

Safeguarding properties from slope erosion and sliding

To ensure slope safety, owners and management corporations should:

  • Be vigilant for slope defects or damages.

  • Be proactive in regular inspection and maintenance.

  • Rectify defects to prevent soil erosion and water inflow as these can cause slopes and their protection structures to fail due to poor maintenance and deterioration.

  • Install slope protection structures [PDF, 356 KB] where necessary to ensure long-term slope stability.
