Pro Tip: Building on Expansive Clay Soil

In this Pro Tip episode I'll give you a way to know if the soil under your property has a high Clay content, and I'll talk about why expansive clay can wreck havoc on your concrete foundation. For more tips on building & remodeling visit my blog at www.MattRisinger.com

    Few notes: Not all clay is expansive!! It's dependant on the type of mineral that makes the clay such as illite, killite, montmorillonite, etc. Search local geographic reports or geotechnical reports on the clay in your area. Moreover, the play doh move is considered a plasticity test, where you want to be able to roll a soil to approx. 1/8" thick, but this is dependent on the moisture and indicates the point at which a soil behaves plastically. To actually determine the amount of clay in a soil you'd want to carry out a hydrometer test which will determine the % of clay on the samples. If you have expansive soils in your area, manage moisture; trees near your house can also affect the foundations. For foundations, essentially more reinforcing is required for structural elements and in some cases pile foundations maybe a more practical option than footings. There are soils expansive tests to determine the amount of pressure the soil may exert on a surface. For slabs on grade, or grade beams typically you may add a 4" thick piece of styrofoam such that the styrofoam displaces rather than the concrete.

Gosh, so glad i did.....again the builder wanted to do the interior walls with gyprock and i totally refused, the movement my pure clay soil has would have cracked the gyprock in no time....don't they build elevated houses down your area? would avoid many troubles.

To make matters worst, I dug a trench around the house, and groundwater started to fill up the trench. Now I have an active pond. With that, I have no choice but to wait until everything dries out. What can I do besides waiting until everything dries?

    In Russia, it is the most common loam soil. The easiest is the foundation of reinforced concrete pillars below the freezing depth. If the groundwater is close, it is necessary to drill below. A more expensive and the most common variant in Russia is a concrete ribbon below the freezing depth. Sorry for English, Google translator.
