Root damage can lead to major, minor and microscopic cracks in stormwater and sewage pipes, but the damage caused by tree roots can be difficult to see until contaminated water (or sewage) starts to become apparent due to smell, or toilets, basins, baths and showers start to back up.
Pressure build-up can be caused by an accumulation of waste food, hair or debris, and that may create pressure at joins or even on the internal sides of the pipes. Wastewater and sewage naturally follow the “path of least resistance,” therefore, it attempts to flow through minor cracks when there is no other outlet.
During landscaping, renovation or remodelling projects, it is easy to puncture or crack pipes by accident. Direct digging can crack pipes easily because they are hidden in mounds of sand, dirt or clay. When the plastic, copper or galvanised pipes are cracked, the damage might not be immediately apparent. Always remember, “dial before you dig”.
