Tree Root Intrusion Can Cause Recurring Blocked Drains in Brisbane
Brisbane's subtropical climate supports vigorous tree growth, particularly during the warmer, wetter months. Tree roots respond to moisture gradients in the surrounding soil, a process called hydrotropism . When older earthenware drainage pipes develop cracks and deteriorated joints, fine feeder roots can enter through these openings and access the moisture and nutrients inside. Once inside, roots branch and thicken, reducing the pipe's internal diameter and trapping wastewater solids. This can lead to recurring blockages, slow drainage and sewage backups, particularly in older Brisbane properties with ageing underground pipework. Plumbers at S&J Plumbing & Gasfitting use CCTV drain inspections to identify root intrusion and assess pipe damage and fix blocked drains in Brisbane homes .
