Two frequent questions I get from houseowners:
My driveway sounds hollow… is that bad?
Sand runs out the end of my drive after it rains… is that bad?
In case you have significant voids or house between the concrete and sub grade or if your drive is on a steep grade, this can certainly be “bad”. Does your drive make a thumping noise when you drive in on it? Possibly it rocks once you drive over it. Can you see between the joints? Are there seen cracks? Does it look like your driveway concrete is sliding away? Perhaps the drive has even sunken down inflicting journey hazards. These are all signs or symptoms that you could be be lacking some sub grade underneath your concrete, which is quite vital to the integrity of your drive.
Four to 6 inches of sand is positioned and compacted, providing base and support for concrete when it is poured. The sand sub grade can settle if uncovered to water repeatedly, inflicting a small area or void between the underside of the slab and the sand. Other causes could also be incorrect compaction, organic soils or lack of sand. Driveways which are on a grade are more vulnerable to water erosion and settling because water runs downhill by means of joints and cracks. These of you who’ve this problem know precisely what I mean.
How can I fix this problem in my driveway?
Drill and fill the voids underneath the concrete (commonly referred to as mud-jacking).
Caulk all joints and cracks with a good quality concrete caulk.
Re direct downspouts and water that might wash out underneath.
How can I forestall this from taking place to my drive?
Caulk all cracks and joints with a very good quality concrete caulk; this keeps water running over the top preventing it from getting underneath.
Ensure that water drains away out of your drive, stopping it from traveling under the slab.
Direct downspouts away from your concrete.
In case you are installing a new drive, ensure the contractor properly compacts the correct amount of sand on your base.
