Sanderstead's hillside gardens demand careful groundwork preparation. Whether tackling waterlogged lawns near Hamsey Green or preparing foundations for that long-awaited summer house, proper excavation makes all the difference.
Response within 24 hours
Those Victorian properties along Limpsfield Road know the struggle - gardens built on chalk slopes that turn into muddy rivers each winter. Smart groundworks solve these drainage nightmares permanently. From French drains threading beneath established borders to complete garden re-grading projects, the right foundation work transforms unusable spaces into year-round havens.
Ground preparation involves more than just shifting soil. Compaction testing ensures patios won't sink after installation. Precise gradient calculations direct water away from structures. Subbase materials get selected based on specific soil conditions - particularly important given Sanderstead's mix of clay pockets and chalk deposits. Every excavation considers existing tree roots, buried services, and future landscaping plans.
Twenty years tackling Sanderstead's unique terrain brings invaluable insight. Local knowledge means anticipating where underground springs might surface, understanding which areas need extra reinforcement, and knowing exactly how deep to dig through varying soil layers.
