What is the load carrying capacity of the screws?

 

The screws come in four diameters (76mm, 89mm, 114mm & 140mm) and various lengths. The load bearing capacity of a screw is directly related to the type of soil it is installed in. Our licensed engineer will be able to select the appropriate screw diameter and length once we understand the project requirements.

 

Can I install the screws myself?

 

We do have small screws that can be driven into the ground by hand and these could typically support a beach umbrella or clothes drying line. They can be purchased from us directly but the larger screws must be installed by Krinner trained and certified personnel. 

 

What can the screws be used for?

 

Krinner ground screws can be used to support loads ranging from a beach umbrella to a house. Contact us and we'll be glad to select a screw to suit your project.

 

Can I purchase Krinner Ground Screws at a hardware store?

 

Krinner ground screws can only be purchased from us.

 

Are Krinner Ground Screws recognised by building codes?

 

Krinner ground screws comply with the National Building Code 2010. Please contact us for a copy of our CCMC evaluation report 13577-R.

 

Will a foundation built with Krinner Ground Screws be cheaper than a concrete foundation?

 

We have found that, depending on circumstances, Krinner ground screws can offer substantial cost savings to traditional concrete foundations. Experience has also shown that they offer substantial cost savings in remote locations or in areas where there isn't readily available concrete. The installation process is quick and the ground screws can be loaded immediately after installation which also leads to reducing cost on projects.

 

Can the screws be installed in rock?

 

Typically, the screws work best in soils, clays and gravel. We have developed techniques for working in locations with boulders and rock and this would take more time and preparation but it can be done. Contact us even if you have a difficult site, we look forward to finding a solution that will work.

 

I have a small yard with difficult access and do not want my landscaping damaged, can you work under these constraints?

 

Our machine is only 36" wide and runs on tracks. We can fit into most tight spots without destroying lawns or plants as opposed to conventional methods that typically damage lawns and landscaping.

 

What about frost?

 

Frost will not be a problem if the screw has been installed well below the frost line.
