Leak investigations around a working building
A leaking supply can affect staff facilities, tenant spaces, kitchens and heating before water appears on the surface. Facilities teams need to know which pipe is losing water, where access is needed and which repairs will restore the supply.
Commercial Leak Detection brings ADI’s services together for building managers and business owners. The office discusses access and operating hours before the survey, with risk assessments and method statements supplied for commercial work.
