BAD DRAINAGE WORK COSTS MORE THAN GOOD WORK EVER WOULD
Drainage installations and repairs go wrong in predictable ways — wrong gradient on a new run, badly bedded pipework that sags, incompatible jointing systems, undersized capacity for the connected flows, soakaways that flood after every rain. Most of these problems don’t show up until 18 months after the install, when the original contractor is long gone.
EcoGas’s drainage installations are done properly from the survey onward. Correct gradient calculation, proper bedding, the right pipe diameter for the connected flow, WRAS-compliant jointing, full CCTV survey on completion. We use no-dig methods where viable to save time and reduce disruption, but we don’t cut corners on the work that has to be done properly.

WHAT PERTH SAYS ABOUT OUR DRAINAGE WORK
Quentin H. — Perth
Section of clay drainage under our drive had collapsed. EcoGas surveyed properly, recommended a no-dig lining rather than digging up the whole drive. Done in two days, no driveway damage, full CCTV confirmation afterwards.
Rosalind J. — Perth
New drainage run installed for our kitchen extension. EcoGas handled the design, council notifications, full install and final building control sign-off. One contractor for the whole job.
Sebastian P. — Perth
Repeated drainage problems from old terracotta pipework — EcoGas surveyed, quoted both no-dig relining and excavation options honestly, and we went with relining. Two years on, no problems.
Trudy A. — Perth
Surface water flooding from poor garden drainage every winter. EcoGas designed and installed a proper soakaway, re-routed the rainwater pipes. Garden is dry through the worst weather now.
