The LEAH Ground Screw works on earth compression. In similar fashion to a wood screw, the LEAH Ground Screw screws into the ground allowing the earth to compress around it. the Ground Screw embeds itself in the earth creating the secure foundation.

Yes. The LEAH Ground Screw has been installed all over the world and continues to be a foundation solution in extreme conditions.

You can choose the professional equipment to install ground screw. You can find from our web. http://..........com/otherbar1686368.htmIf u need ,pls contact us.

No.Just like any product, the LEAH Ground Screw may not be the right product for every project.However, the applications ranges are so numerous, that we know it is just a matter of time before you have a use for them!

Contact us and we can discuss your project and decide what screws are right for you.The more information we have the easier we can make the right decision.Factors such as soil type climate,application and required load are just a few of the factors we use to determine the proper screw you need for your project.

The LEAH Ground Screw is comprised of steel that has been double, hot dip galvanized. Galvanized steel "is the most recycled material in the world with approximately 90% of steel and 80% of available zinc recycled" (American Galvanizers Association).In addition to that, the LEAH Ground Screw requires no concrete or digging and has a minimal physical footpr...

When you first drill the initial hole down about 600mm, the soil is typically soft enough that calibration is easiest at that point. From the 600mm depth until it wedges tight is the critical time. In the majority of cases thus far, the softer the soil is, the more easier the calibration is .Should there be rock or realdense soil, the use of water to soften the soil is especially helpful in calibr...

Keep in mind that load can be either mutative weight or static. For example, a flag is measured in static weight because, depending on the size of the flag, how much wind load it can catch and how it is mounted with tension lines or directly to the pole, rigid. How big in size more so than how much it weighs contributes greatly to what load it effects. Also, the density of th...

The soil conditions issue is conditional on how large the rocks are as compared to the soil composition.In the situation of there being more rock than dirt, an alternate method of installing the ground screw should be evaluated.

Always wear protective eyewear and protective sheathing for hands when working with equipmentor tools that require such protective wear. Carefully evaluate or ask the properauthoritiesassociated with the location you estimate working in, what dangers could exist should youdrill to penetrate the soil in that location. Use caution, anticipating possible resolve for conditionsthat might arise from gr...
