OK, so I am trying to figure out this watering the foundation thing...
I understand the reasoning behind it, but not sure when, how much, how long, etc... I have a sprinkler system, which I currently have coming on on auto once a week, it does a good job of wetting down everything, and I have each zone running for 35 minutes, so it gets a good soak. Should I still run soaker hoses around the house, and fire them up? Or maybe just boost my sprinkler to twice a week? DFW area by the way.... From what I understand over watering can be just as bad as under, so I want to try to hit the good balance.... Thanks much on any advice... |

Curios about this to. I use to level houses years ago when i was just out of high school (20+ years ago). Back then, i remember the owner telling people not to water there slabs because your only getting the outside edge. The ground expands on the outside but not under the slab which just makes it worse by adding more pressure to it. Kinda of like spraying water on your outside ac coils. It seems to work but causes more problems by clogging them up over time. Now it could have been his sales pitch to have that seep pipeing installed under the slab or something but always wondered if it helped or hurt for real.

Our builder (new home, built in 2006...which I've since sold lol), told us as long as the grass was growing around the foundation, no issues. If you have it start dying, ground pulling back, it needs some water.
There was some concern as the years went by, saw some cracks in the corners of the home (drywall), some cracks in tile, couple small cracks in patio/front porch cement. But it's all normal, inspector had no issues. |

We run our sprinklers a couple of times a week and we have no issues. The ground near the slab is moist and not cracked and we have plenty of grass. Running your sprinklers once a week may not be enough in this heat so adding a soaker hose might be in order. If you were to bump up you sprinklers to twice or three times a week you should be good.

I was on a jury back in the '80s. The case was about a slab that had sat unused for 3 years before a house was built on it. One thing I remember from the engineer that testified was that the ground can dry up to 3 feet from the edge of the slab. One way to prevent problems is to use a soaker hose. Another was to put something, sidewalk, gravel flower bed, etc. around the house so it extends the edge 3 feet from the slab. Most people just run a soaker hose around the slab. If the ground gets muddy turn it off until it dries, but it's hard to overwater with a soaker. |

As far as damage to your home, it can make a difference. Some towns building code is adequate to cover your ass, depending on when and where your home was built. The tech available now could support a house on five gallon bucket of superbadassmicrostainless gel. I think Hi-Point
makes it. Either way, I would water a 3 foot space around your foundation to the point where it does not dry out to the point where there is a gap between the dirt, and your slab. That does not guarantee that you won't have slab problems. The clay/soil in Texas is not slab friendly. Good Luck. |

You should have enough water to keep the dirt around the foundation damp and semi soft, but not so much as to make a muddy slurry.

You need to change your settings and water more often. Mine is set to run 8 minutes per zone every other day.

I can certainly water for less time more often.... I know things are good right now, the house was built in 2005...I had a good home inspection done, and the inspector checked the slab, mortar joints and bricks, and all the stuff insidea (cracks in walls, uneven floors, sticking doors, etc, etc...) I have good soil and grass along the exposed parts of the slab, not too much, not too little exposed... I just want to make sure I keep it all in good health.... Thanks for all the advice and suggestions |

You need to water turf heavily on e or twice a week, not lightly more often. The way to check is you want the soil moist 1" deep. The amount of time the zones run depend on what heads you are using. They do not all put out at the same rate and some are much less efficient than others. |

There are 2 different irrigation watering programs outlined for the north Texas soil by TEEX (Texas A&M Engineering Services) and TEES:
1. Irrigation for turf/grass management. Basically it is to water your grass until the soil is wet 6 inches deep. Then let the soil dry out until it stresses the turf (generally 5-10 days in Texas weather) and re-water to a moisture depth of 6 inches. http://publications.tamu.edu/TURF_LANDSCAPE/PUB_turf_Maintaining%20Bermudagrass%20Lawns.pdf 2. Irrigation for foundations. Basically, you don't want to see separation between the foundation and the soil around the foundation. https://dallas.tamu.edu/media/75260/protecting_foundations_under_dry_conditions.pdf To combine both into a singular irrigation plan TEEX said that if your grass is good, and you follow that irrigation regimine that you'll never have a problem with foundation moisture levels as that irrigation guidance is much more restrictive solely to keep catastrophic issues from occurring during a period of extended drought. |

Here's a detail for an irrigation system my firm designed for a friend that built a new house on very expansive soil. We followed the Texas A&M guidelines on foundation watering. We added a separate drip zone using two lines of Netafim Techline drip tubing, just for foundation irrigation, and installed a Baseline S100 soil moisture sensor. Once you dial in the percentage of moisture content in the soil, the system keeps that same percentage the majority of the time. The reason it doesn't keep it the same all the time is during a major rainfall event, the soil moisture percentage spikes.
Here's the detail. This was the soil moisture sensor used. http://www.baselinesystems.com/products.php/watertec-s100 |
