Pocket PenetrometerThe Use of a Pocket Penetrometer
There are many ways to identify the load bearing capacity of soil. You can take soil samples and send them to a laboratory. You can ask an engineer who has been specially trained in the analysis of soil. Or, you can do a very good job with a tool called a pocket penetrometer. If you follow a few simple directions, you can get a very good idea of the load bearing capacity of soil. And it won't take long.

First, the scale of a pocket penetrometer is graduated in tons per square foot. To use the charts in a factory manual, we'll have to convert that to pounds per square foot, so we'll multiply that by 2,000 pounds. For instance, the number 1 on the pocket penetrometer translates to 2,000 pounds or 1 ton. 1.5 means 3,000 pounds or 1.5 tons, and so on. The charts in most manuals go to 4,000 pounds. Any values you find above that will still be considered 4,000 pounds.


Notice that there is a spring in the handle of the pocket penetrometer and that the body of the mechanism slides into the handle. The tip of the probe has a little grove around it exactly 1/4" up from the bottom. This is the part that is inserted into undisturbed soil that has the same moisture content as the soil under the home. What this means is that you can't test sunbaked soil or loose fill. Never place a home on loose fill. Any fill needed should be compacted to the original density of the soil prior to its being disturbed.

Finding the same moisture content may require that you dig into the ground 6" 8", though in some areas your footings will not be down that deep. In other areas of deep frost you will have to test the soil at the bottom of the footings how ever deep they are. What you are looking for is ground that has not been affected by the sun, just like the ground under the home will be after the home is installed. That's where you should take your readings. Insert the probe to the little grove on the bottom then read the placement of the red ring up the barrel. If you take five readings in the same general area, throw out the high and low readings, average the remaining three readings, this gives you a fairly accurate reading of the load bearing capacity of the soil.

There are a few things to watch out for. Pocket penetrometers do not work on sand or gravel. If you have sand use a 1500 lb. load bearing capacity. If you have a layer of gravel test the soil under the gravel. Don't put the Penetrometer on stones larger than it's tip, this will cause an inaccurate reading.

The time it takes to accomplish this task is certainly less than a couple of minutes and will ensure the success of the rest of the installation. We didn't have to do this 40 years ago in the trailer business, but we're not in that business anymore.
