Foundation Repair in Grayson County, TX

Around the centre of Grayson County, a sample of 49 points found that 33 of the 47 points with a soil reading sat on soil rated high or very high for shrink-swell, and 14 of those are rated very high. That is the starting fact for anyone searching for foundation repair in Grayson County. Clay in those classes swells with moisture and shrinks as it dries, which lifts and drops whatever rests on it.

The rest of the sample: 1 point fell on water and 1 on urban land with no soil reading. The commonest soil series were Austin at 7 points, with Normangee and Fairlie at 6 points each. The sample covers an area about 21 miles wide around the county's centre, so it cannot speak for a particular town or street. In the same sample, 4 of 48 land points sit inside the 1% annual chance floodplain. A homeowner can look up their own address on FEMA's flood map, because wet ground by a foundation keeps clay swollen.

The median home in Grayson County was built in 1984. Of all homes, 19.5% were built before 1960 and 41.3% in 1990 or later. The census does not record foundation type. As a rule of thumb in Texas, pier and beam shows up more in older houses and slab in newer ones.
