Ground Screw Extension 63.5 x 580 mm - Per piece

Are you planning on building a heavy structure? Then you will have to use an extension piece to increase the length of your ground screws. This allows you to bury the ground screw deeper, which increases the load-bearing capacity. Further on, you will find the load-bearing capacity for different lengths of ground screws. The total length of this extension is 580 mm. Note: the added length is 500 mm because 80 mm of the piece will be inserted in the ground screw. The required fasteners are included.

Build your own foundation

Building your own foundation is simple with Wovar's ground screws. You can drive them into the ground manually with the corresponding installation tool. Insert the tool in the ground screw or extension piece, and turn the ground screw. For a step-by-step guide, you can go to the product page of the ground screws.

In the graph below, you can see the load-bearing capacity of a foundation with ground screws in clay ground. The numbers are an approximation. For sand, the load-bearing capacity is slightly higher, but we recommend not going beyond the weights mentioned in the graph. The deeper the ground screws, the higher the load-bearing capacity.

(The values in the mentioned load-bearing capacity are lowered with a safety factor of 35%. Wovar is not liable for damages due to an erroneous choice of ground screws.)

Lifespan ground screws

Wovar's ground screws are maintenance-free and incredibly strong. They are suitable for both temporary and permanent structures. The large lifespan means you do not have to worry about your foundation. Of course, it is important to have a great foundation to start with, so use a large enough number of ground screws at the right depth. This will ensure a solid foundation for years to come. You can even install ground screws in the winter.
