Drain Faults

Defect: fractured pipe
Cause: Pressure above ground
Consequences: Cracks or fractures in drains leak water which destabilizes the surrounding soil. This will result in further damage to the drain and even subsidence to buildings near by

Defect: collapsed drain
Cause: Several possible causes
Consequences: Drain becomes unusable with high likelihood of frequent blockages, environmental damage, and building subsidence.

Defect: tree roots
Cause: Roots seeking moisture
Consequences: Materials flowing through the drain will snag on the roots causing continual blockages. Roots dislodge or crack the drain resulting in leakage and further damage.
