North Texas just had a pretty intense storm come through over the week-end. If after the storm you noticed wafer standing around the foundation of your residence, it is time to address the problem. Standing water causes the North Texas soil to become over saturated and swell up. Once the dryer climate will start, that same soil will shrink incredibly, causing stress to the foundations of your residence.
Remember the a constant (or as constant as it can be) moisture in the ground is the key to your residence foundation's health. Have your drainage issues addressed soon!
