Noticed in a few threads over the last week that some of you are going through a drought in areas that don't usually experience it.

This PSA applies to you if you live in a home with a slab foundation in clay/expansive soils. Pay special attention if you see cracks in the soil in your yard like so.

View attachment 24706

When the clay dries out, it shrinks. Horizontally we see cracks, vertically it just collapses on itself and is no longer supporting anything above it, like a slab foundation.

Simple fix/preventive maintenance. The most boring yet valuable video in history below if you are at risk of drought related foundation damage.

This is real deal stuff with these drought conditions. We moved to Texas from Mississippi in ‘92. We moved into our new house in September. I didn’t understand anything about the soil or the climate but I learned a lot about it before the end of that first year. I met a bunch of guys in those first few months and we all met in the mornings at this little place where we drank coffee and talked about just about everything. One guy was a Captain on the Waco Fire Department, one was a Texas Ranger, one of them owned a gun shop, a couple were pretty well-known building contractors in town and a couple others owned construction companies. All of them grew up and lived in central Texas and had lived most of their lives in the area. One morning in late May that first year, my wife brings to the fact that several doors in our house were not opening/closing like they had been moving in. Our garage we detached from the main house and connected to the house via a covered sidewalk. I noticed that the door from the garage to the sidewalk was getting very hard to open/close. I had built houses back in Mississippi and knew that issues like these are an indicator of foundation problems. I was devastated thinking that I had purchased a home with foundation problems. The house was 4 years old when we bought it. Well, I walked into the coffee shop one morning and told my buddies what was going on at my house. These guys all knew the neighborhood where I lived and most of them knew the guys who built my house. They all started laughing at my story-I couldn’t believe they found humor in hearing my problem. One of them said, say, ya’ll don’t have clay soils in Mississippi? Yeah, we certainly have plenty of clay soils but where I had lived it was more of a sandy loam. I jumped into the truck with one of the contractors and we got out and walked around the house. He told me to look at how far away from my foundation the soil was-there was about a 4” gap between the soil and the edge of my slab. He told me to go buy enough soaker hoses to lay all the way around my house and to turn them on at dark and let them run all night-turn them off during the day and back on the next evening and let them run until the soil was back against the foundation all the way around the house. Took 3 nights to close the gap all the way around, but after the first 2 nights my doors were all working like new again. We lived there for 12 years and I never had another problem-if I saw the soil retreating away from the slab an inch or so I just ran the soakers for a night. I had a friend who was a rancher who sent a Mexican who worked for him to the store to buy a 125’ of heavy chain with hooks on each end. They opened the tailgate on his truck and pulled the chain out onto the tailgate. Somehow one end of that chain started sliding over the edge of the tailgate and just happened to find one of those cracks in his field-by the time they realized what had happened the entire chain had completely disappeared down that crack and was never seen again.

Thankfully, I've yet to see anything that drastic in my yard, but I definitely check the boxes on drought-like conditions and clay soil. I tend to always notice more cracking in grassless areas like the circle of dirt on the underside of our trampoline, but I'm not seeing anything too bad right now in the grassy areas around the house. Completely uneducated guess here, but in addition to providing some shielding against the direct sun, I wonder if bermuda grass has a tendency to hold the soil together a little better than in other areas since it's so damn strong.

Who knows, but I'm gonna continue to keep an eye out. I have legit not seen anything like this dry spell in all my 40 years

Put up with the soil crap for 40 years in the Dallas area until we moved to Ridgeland this January. Back at our house in Texas the soil would retract from the street curb by 6 inches or more and that was watering 3 - 4 times a week with the sprinkler system. Soil cracks were everywhere. Had to have piers installed under the slab to keep it level, and even with that I was constantly repairing cracks in our sheetrock. Here in Ridgeland it's all green and I haven't turned the sprinkler system on yet.

I've been dealing with cracks in my yard like that for thirty years. The only way to mitigate that is to float the slab on sand and even that won't stop it all. Ram Jack will fix everything else.
