- 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

Would love a video on how to build a basement in a clay rich yard. E.g. multilayer drains, gravel barrier, fabric protection and soil compaction.
So, what did we accomplish with this
Looking forward to future videos on this subject matter. Living in Mississippi, we too have a high clay content in our soil. Thanks again for another great video.
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.
I can't wait to see the next videos on this.
So where is the next video? It’s been 7 years ago
Engineer was not involved in 90% of homes in Houston homes. Cookie cutter homes, streamlined inspections, homie/favor/fast building contracts.
Thank you. Your videos are a great service to all architects, contractors, and the high performance home building industry in particular. I know several team members on the certifications team at Earth Advantage watch your videos.
Matt I'm surprised you dont have your own tv show yet! Seriously, you are an outstanding presenter, highly knowledgeable, with top notch advice. All the best. -Cheers
That’s why they’ve come out with the new tella firma foundations in Texas. Or you can excavate it out & bring clean fill dirt
Zero building tips. Zero.
OOOOOOOOOOOOOOOH I CAM"T WAIT UNTIL THE NEXT EPISODE COMES OUT!
Matt, what's the link to the sequel for this one on expansive clay soil? I looked at your posted videos, but you have so many, all of which are worth watching. : D
What kind of foundation recomended for this soil.!!!
Put it in a kiln to make a ceramic cover then bury the tiles at an angle away from the foundation
Matt, we're plagued by the same soils here in Jackson, Mississippi. I'm a home builder/licensed home inspector. I've measured dozens of homes here, some 9 inches out of level. It's important to know what's under your foundation. I too recommend soil tests and GEO engineer reports.
This is a really helpful video. Seeing the clay like that makes sense versus the black soil that breaks apart.
Is expansive foundation sub-grade the same as reactive?
I just want to do a small pole frame lean to on my place for animals. Our clay is largely glacial lake left overs from when the lower Puget sound/Chehailis river was a melt water channel surrounded by lakes, and the tip of a giant Puget lobe ice sheet to the north. This clay we have is soft and squishy/stickey durring the wet winter months, and hard as a rock durring the summer...
for sticky clay soil, down to 8' ( dug trenchs to find that out ) at what level would you recomend ( I will get it engineered by a professional ) could rock be put down? In other words, how deep into the clay?
