Hot Tar Crack Sealing: The First Line of Defense for Your Asphalt
Cracks in asphalt may not look urgent at first, but they’re often the starting point for much bigger pavement problems. Once a crack opens, water can move below the surface and reach the base layer that supports the asphalt. When that base becomes soft or unstable, the pavement above it starts to shift, sink, and break apart.
Why cracks get worse in Oklahoma
Oklahoma weather can be tough on parking lots. Heat, sun, rain, and sudden temperature changes all put pressure on asphalt. During cooler months, water that gets into cracks can expand and contract as temperatures change, which forces the crack to widen over time. During warmer months, heavy traffic and UV exposure can dry out the surface and make existing cracks spread even faster.
That’s why timing matters. Crack sealing works best when the damage is addressed early, before water has had time to weaken the base below the asphalt.
How hot tar crack sealing works
Hot tar crack sealing is designed to fill and seal open cracks with a flexible material that helps keep water out. The area is cleaned first so the sealant can bond properly. Then heated rubberized material is applied into the crack, creating a seal that can move with the pavement as temperatures change.
This is different from simply covering the crack. The goal is to protect the structure of the pavement and slow the spread of damage. For commercial parking lots, drive lanes, and high traffic areas, that protection can make a noticeable difference in how long the asphalt lasts.
A small service that protects a large investment
For Oklahoma businesses, crack sealing is one of the most practical ways to protect a parking lot without jumping straight to major repairs. It helps preserve the base, reduce water damage, and delay larger failures that cost more to fix.
If your lot has visible cracks, don’t wait until they become potholes. HCI Paving Solutions can inspect your asphalt, identify areas that need attention, and recommend a crack sealing plan that helps protect your pavement before small problems grow.
