How many kilograms can a screw foundation support?

That depends on several factors. In the load table you will find the values of the load capacity determined in the semi-solid loam soil type. The values are reduced by a safety factor of 35%. Please note that the values listed are an approximation.

Why do I need to pre-drill?

You give the screw a slight head start here to screw it in the right position.

How long does it take me to install one screw post?

This depends on the type of soil, length of the screw post and your strength. On average, it takes about 15-20 minutes.

How many screw posts do I need?

The number depends on the number of posts, pillars or supports of your application. Also, the span of certain beams and girders should not be too large to avoid cracking and breaking. On our product pages, we advise you on the maximum load per screw post and possible applications.

What is the lifespan of a screw foundation?

Of course, this depends on soil conditions but this can add up to many decades. You can even reuse screw piles.

Can screw piles also be used in weak soil?

Screw foundations are suitable for all soil types. Depending on the soil/soil conditions, we recommend using shorter or longer screw piles. Do you have an application around the house in mind and are unsure about the soil conditions? Feel free to consult our customer service.

How do I install the DIY screw posts?

The Do-It-Yourself series is easy to install yourself to a depth of approximately 1.5 meters. This is done with a manual screw-in spanner. Watch the instruction videos yourself.

For heavier applications, or applications on weaker soil types, we always recommend the PRO-Series. These can also be installed (by professionals) provided you have the right electric screwing machines and adapters. For assembly of our PRO-Series, you can request a no-obligation quote via the foundation guide.

Can I install screw foundations myself, even as a professional, for a large project?

We have several electric machines in stock for installing screw foundations. If you would like to install screw foundations yourself on a regular basis, it is certainly worth purchasing an electric machine. Contact us directly about the possibilities.
