Expansive Soil And Foundation Cracks
This column was SO GOOD that I shared with the 31,000 subscribers who read my April 8, 2018 AsktheBuilder Newsletter.
When the soil starts to dry out, the clay soil will contract, creating large cracks in the ground. This can spell big problems for your foundation if you have a shallow foundation on a garage or room addition or if your house is built on a slab. These soil settlement cracks indicate that the soil is extremely dry. This can lead to the cracks in your foundation.
To cure this, the soil down about two feet needs to receive water. The water has to get down to the bottom soil quickly. Use an auger to drill holes 2 feet on center and 2 feet from the house all around the house. This will allow rain or garden hose water to travel down into the soil without getting side tracked by the grass and flowers.
Once the holes are drilled, fill them with grounded small, pea gravel. Fill the hole all the way with the gravel. Use your garden hose to fill the hole with water. You will be amazed at how much water the hole will hold.
These holes and gravel will get the water down into the soil and get it moisture. This reduced the ground shrinkage and helps prevent those foundation cracks.
