Damage Assessment

1. Subsidence

• Ground sinking beneath foundations
• Often caused by clay shrinkage or leaks
• Visible cracks in walls and floors

2. Heave

• Ground swelling, often clay-related
• Pushes foundations and floors upwards
• Common after tree removal or wet seasons

3. Erosion & Washout

• Soil washed away by water flow
• Undermines foundations and retaining walls
• Common near slopes and poor drainage

4. Foundation Failure

• Existing footings cracking or moving
• Walls leaning or stepping cracks appearing
• Doors and windows sticking or misaligned

minor Repairs

• Monitor cracks with telltales
• Improve surface drainage
• Repoint affected brickwork

moderate Repairs

• Localised underpinning of weak sections
• Install French drains or soakaways
• Targeted soil stabilisation

major Repairs

• Full underpinning of foundations
• Resin injection ground stabilisation
• Structural reinforcement and rebuild of damaged walls

When Replacement Is Needed

• Cracks appearing in walls or floors
• Doors or windows no longer closing properly
• After flooding or burst pipes
• Following nearby excavation or tree removal

Installation Steps

1. 1

   Visual Inspection

   • Survey internal and external walls
   • Check floors, ceilings, and openings
   • Photograph and record all defects
2. 2

   Crack Monitoring

   • Fit telltales across active cracks
   • Record movement over weeks or months
   • Identify whether issues are progressive
3. 3

   Ground Investigation

   • Trial pits next to affected foundations
   • Soil samples from key depths
   • Check for leaks from drains or services
4. 4

   Engineering Report & Plan

   • Diagnose root cause of damage
   • Grade severity and risk
   • Specify repair strategy and sequence
