Failure types are common across the board for carparks and are usually related to “crocodile cracking,” where the pavement suffers from structural failure related to heavy loads. Betta Asphalt works with commercial clients across the Melbourne Metropolitan area and Macedon Ranges Shire to service carpark repairs for body corporate and facility management companies.
The Betta Asphalt Approach
Betta Asphalt takes a holistic view to carpark repairs, with considerations around traffic volume, the age of the asphalt and degree of damage:
• Crocodile cracks are fixed by removing the existing failed asphalt
• The sub base is then stabilised and if necessary excavated further down to enable additional thickness in the new asphalt surface
Why does asphalt fail in carparks?
Crocodile cracks often form as a result of:
• Weak areas in sub base
• Asphalt thickness not considered for actual traffic passing over it
