One of the most common repairs is the joint between the garage and the driveway. If you’ve experienced this, repaired it, to only have it happen again you’re probably not a happy camper.
Frustrating? A waste of money?
Absolutely. We’d rather you spend money on other pleasures in life than fixing a pavement collapse situation at your garage over and over again.
We’d like to elaborate why this happens and what can be done to permanently fix the issue.
Certainly there are many particulars beyond our scope of expertise, we’ll only expound on what we experience.
Each concrete block contains two large holes. Generally the corner blocks of a structure are filled with concrete but the center ones are left open.
This is where issues can happen years later.
Initially soils and base aggregate for the driveway are moved around and fill these holes (to some extent) but those materials are neither compacted or filled in a way that ensures any permanent stability. So then...
If there’s a place for it to go. It will go.
Once any of the top layers of soil move through those open holes of the concrete block the surface of the driveway will start to collapse. If you have a concrete driveway, you won’t notice as much of a collapse? Why?
Concrete is a rigid pavement and will create a “bridge” over an unsupported area.
We actually have seen some major wash-out under garage floors, up to 6’ deep because of concrete’s amazing bridging abilities.
that as it expands and contracts with swings of temperature the oils in the asphalt will become rejuvenated and self repair where concrete’s rigidity is not as forgiving.
Here’s where the con doesn’t work in our favor.
When the pavement surface of asphalt is unsupported, it begins to collapse, especially in areas where it’s exposed to loads (your car driving over). The adjacent pavement will join in and collapse as well.
Then the driveway joint can be reconstructed with compacting base aggregate and new asphalt.
There! You’re good to go not having to revisit that issue any longer. Now you have the time and energy to focus on all those other household projects!
