Paving movement can cause costly damage to sewer pipes.
Learn why paving movement is causing damage to sewer pipes.
Anything incorporated within paving can be damaged from its movement. Usually sewer or plumbing pipes. This can be rectified by creating enough clearance between pipes and concrete. This will allow further movement without causing damage to pipes below the surface.
Aleviating public misconceptions and fears of paving movement.
I am often asked: The paving has moved significantly, will it affect the house?
People often confuse movement of paving with structural damage of a building. They are independent of each other, therefore can move separately without affecting either.
Causes of paving movement and should I be concerned?
Movement of paving is a common occurrence, usually caused by loose soil being placed after digging foundations of a building without compacting the soil before the concrete paving was laid. The degree of movement (usually dependent on the type of soil) can be severe and scary to a lay person.
When you should be concerned about movement of paving.
If it moves to such a degree that it causes safety issues of tripping. When it causes damage to plumbing pipes below the surface and leaking of the pipes. This can cause foundations of buildings to move if not rectified.

Paving movement !
- Generally the only time movement of paving becomes a problem is when a sewer fitting is incorporated within the concrete (without appropriate clearance to allow for movement) this may cause damage to the PVC pipes (below the surface).
- This can be costly to rectify as the concrete would have to be removed and damaged section of the pipes repaired or replaced.
- This can usually be alleviated by creating a gap around the item/structure that is incorporated within the concrete, this allows either to move independently without causing damage.
