About these reports
Percolation and soakaway tests. A percolation test measures how quickly water drains away into the ground on your site.
Contaminated land report. A contaminated land report, usually called a Phase 1 desk study or preliminary risk assessment, checks whether past uses of a site could have left pollution in the ground that might harm future residents.
Topographical survey. A topographical survey measures the exact shape, levels and features of your site, and is usually the first thing an architect or designer needs before drawing up plans, especially on sloping ground or where levels matter to the design.
Asbestos survey. If your home or building was built or last altered before 2000, it may contain asbestos.
Drone survey. A drone survey uses a small unmanned aircraft (a drone, or UAV) to photograph, film or measure a roof, building or site from the air.
