Any asphalt surface is only as good as its sub-base. When the sub-base breaks down your asphalt will follow quickly. These repairs are often the most expensive but, can be avoided with proper installation and maintenance of your asphalt. In some cases drain tile may be needed to divert existing underground water from running under your parking and destroying your sub-base.
Signs that you need a Full Depth Repair
You have mud pumping through your pavement.
Your asphalt appears wavy and weak.
Causes of Sub-base Damage
Something that weighs more than your lot was designed to hold drives on pavement.
Water is somehow getting to your sub-base and compromising its stability.
