About these reports
Percolation and soakaway tests. A percolation test measures how quickly water drains away into the ground on your site.
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.
