Common Paving Installation Problems

Most paving installation problems have a ripple effect in that a problem is a consequence of another problem, which leads to a chain of endless issues and eventually it could lead to irreparable failure of a paved site.

The installation of paving is technical. We therefore recommend that you consult our simple guide to selecting a good contractor. These are merely guidelines highlighting practical questions that one should ask before hiring an installer.

We encourage you to take note of the most common paving installation problems below:

Earthworks

Poor Earthwork Preparation For Paving

Paving problems are mainly caused by inferior earthworks. When paving sites sub base has failed due to incorrect earthworks the result will be disastrous and irreparable.

Compaction

Poor Compaction Of Paving

Inadequate compaction of sub base will cause pavers to sag which will result in water ponding.

Drainage

Water Ponding On Paving Due To Poor Drainage

Incorrect drainage will cause ponding and will infiltrate the sub base which will cause it to fail.

Edge Restraints

Paving Edge Restraint Failure

Inadequate or inferior edge restraints will lead to movement and subsequent loss of jointing sand.


Bedding Sand

Paving Failure Due To Insufficient Bedding Sand

Inferior or insufficient bedding sand might cause pavers to move and break.

Careful Handling

Poor Handling Of Paving Blocks

Careless and indiscriminate handling of paving will cause chipping and breaking.

Cutting
