A few words from our happy customers

F.A.Q

Have questions about our screw pile foundation solutions? Here are the answers to some commonly asked questions:

What is the GroundPlug® Easy Mounting SystemTM?

The GroundPlug® Easy Mounting SystemTM is a no-dig, no-pour screw pile footing alternative for residential outdoor building projects. The GroundPlug® Easy Mounting SystemTM is based on the GroundPlug® TwisterTM screw pile footings that come in different size variations to suit your project. The screw pile footings are super easy to work with and can be screwed into the ground in minutes with common tools like an impact wrench, or a hand tool with socket wrench if you are just installing a few.

How do I use the GroundPlug® TwisterTM as footing?

Once you have placed and aligned the support beams of your shed, deck, carport, pergola, cabin, garden swing, playhouse, trampoline or whatever construction project project that needs a solid, durable foundation, the GroundPlug® TwisterTM screw pile footings are easily driven into the ground with an impact wrench and mounted to the beams with the supplied bracket, bolt and screws. After this all supports placed for alignment can be removed.

How do I decide which size GroundPlug® TwisterTM footing to use?

The GroundPlug® TwisterTM footings come in 3 different thread diameters: M10, M12 and M16 measuring accordingly: 10 mm, 12 mm and 16 mm in nut dimensions. Each variation comes in a numbers of lengths with respective extender pieces for deeper reach.

Our engineers are on hand to calculate the correct size and quantity for your projects. This service is free of charge. all you need to do is fill in the appropriate form below. Your calculation will be completed within 1-2 business days.

What happens if there is a rock in the ground?

The GroundPlug® TwisterTM screw pile footings are actually much easier to work with in rocky ground than concrete footings. The fact that it only takes 20-30 seconds to install means that you find out much sooner if there is an obstacle in the ground than you would when digging for traditional concrete foundations.

Then you have 3 options:

The easiest solution is to simply move the screw pile placement slightly to one side. Alternatively, if the rock is too large might need to dig it out before installing the GroundPlug® TwisterTM screw pile.

Another option is to drill through the rock if possible. In this case you will need to pour some concrete to support the screw pile footing, as the spiral cannot grip the rock section.

Are the GroundPlug® TwisterTM screw piles affected by frost?

We have many years of experience mounting our steel footings for the railway and highway industry in Scandinavia, working in conditions of hard frost. The design of our products is adapted to cope with tough conditions and the GroundPlug® TwisterTM screw pile footings were developed also for installation in frosty conditions and climates prone to heavy winter frost.

If your structure is sensitive to even minor displacement you should choose a longer screw pile that will reach frost free ground. Needed length will depend on the geographic location.

Do you use the same calculations as for concrete foundations?

The GroundPlug® TwisterTM screw pile footings can handle the same loads as equivalent concrete footings. Just be sure to select the correct  GroundPlug® TwisterTM screwpile footing size for your project and soil conditions.

Is the GroundPlug® Easy Mounting SystemTM a more expensive solution?
