Drainage Services Across Surrey

Surrey's drainage sits on three contrasting geologies: London Clay in the north around Kingston, Epsom and Woking, the chalk of the North Downs through Guildford and Dorking, and the Bagshot and greensand sands of the south-west heaths.

London Clay shrink-swell is the biggest single cause of cracked and displaced older drains in Surrey, made worse by the county's exceptional tree cover — mature oaks and limes both dry the clay and push roots into every open joint. On the chalk, winter groundwater rise causes heavy infiltration and, in wet years, genuine groundwater flooding along the Mole and Wey valleys. On the sands around Camberley, Farnham and the Surrey Heath, a leaking pipe washes out its own bedding, creating voids and sudden driveway collapses. Large detached properties often have long private drain runs, pumped basements and multiple soakaways that no one has inspected in decades.

We survey and reline rather than excavate wherever we can, which protects the mature gardens and hard landscaping these properties are built around.
