Crack Sealing

Crack Sealing is the process of sealing cracks in sealed roads with a hot polymer/rubberised bitumen sealant.

The main purpose of cracking sealing is to prevent moisture finding its way into a road pavement.
It is also used to seal cracks prior to an asphalt overlay in order to prevent reflective cracking.

Crack sealing has traditionally been a manual process, but in recent years there have been a number of attempts to design robotic crack sealing solutions.(2)(8)

Crack sealing is not an appropriate treatment for crocodile cracking.

Preparation

To ensure a good result, cracks should be cleared of weeds and debris prior to being sealed.

The most common method for cleaning cracks is the use of a compressed air jet, but sometime a mechanical device such as a wire brush may be necessary.

Where vegetation is present in a crack (above) it may need to be treated with herbicide prior to being jetted or brushed.
