Those challenging slopes behind Victorian terraces in Old Coulsdon need more than ordinary retaining solutions. Stone-filled gabion cages blend engineering strength with natural aesthetics, creating features that complement both traditional and contemporary properties across CR5.

Coulsdon's position on the North Downs creates distinctive landscaping challenges – particularly for properties backing onto the chalk escarpment. Gabion technology offers flexibility where traditional concrete walls would crack or shift. The wire mesh cages adapt to ground movement while maintaining structural integrity, making them ideal for properties near Farthing Downs or along Brighton Road's steeper sections. Local limestone or flint fill creates visual harmony with surrounding geology.
Installation begins with precise excavation to stable ground – crucial given CR5's mixture of clay caps over chalk. Galvanised steel cages interconnect using helical spirals, forming a monolithic structure without mortar joints. Each basket fills systematically with angular stone, compacted in layers to prevent settlement. Drainage channels behind the structure manage water pressure, preventing the washout issues common in Coulsdon's winter months when surface water overwhelms standard retaining methods.
Twenty years handling Coulsdon's geological quirks means anticipating problems before they arise. Properties near Kenley Common often encounter unexpected chalk seams requiring adjusted foundation depths. Recent projects include tiered gardens in Woodplace Lane and boundary walls for new developments off Marlpit Lane.




Rated 4.9/5 from over 280 verified reviews
Basic gabion walls start around £180-220 per square metre, though CR5's sloping sites often require additional groundwork bringing totals to £250-300. A typical 15-metre boundary wall averages £4,500-6,000 including foundations and drainage.
Absolutely – from Smitham Bottom to Happy Valley, including all CR5 postcodes. Regular work takes us through Old Coulsdon village, the Caterham bypass estates, and newer developments towards Kenley aerodrome.
Standard residential walls complete within 5-7 working days. Larger terracing projects or those requiring significant excavation in Coulsdon's chalk typically span 2-3 weeks, weather permitting.
Every installation carries decade-long structural coverage. The galvanised cages resist corrosion for 50+ years, while proper stone selection ensures colour stability. Documentation includes maintenance schedules specific to Coulsdon's climate patterns.
Definitely – the open structure allows trailing plants to weave through gaps. Sedum, ivy and alpine species thrive in gabion walls, softening industrial appearance whilst maintaining structural function. Irrigation pipes install during construction for automated watering.
