How does a SIP system work?

A screw injection pile is a steel pipe pile with a diameter of, for example, 88.9 mm and a pile tip with a diameter of 250 mm. The drill tip has an opening. During drilling, a mixture of water and cement (cement grout) is injected through the SIP. The cement grout acts as a lubricant for drilling, and it hardens around the pile. Ultimately, this results in a pile foundation of cement-soil mixture with a steel cylindrical core and strong rigidity.

The screw injection piles provided by Solines have conical internal and external threads at the ends. They can be therefore be screwed together quickly and drilled to great depths. The screw injection piles of 106 cm have 6 cm of thread. When these pipes are screwed together, the effective length is therefore one metre per pipe. In the Netherlands, only a few foundation companies have the expertise to apply foundations with screw injection piles. Solines keeps the most commonly used diameters of SIP pipes in stock as standard. This allows us to deliver within one day.

Custom drilling points

You can also order your screw injection piles including drill points. Solines has expert welders who produce the drilling tips with blade widths of 250, 300 or 350 mm in our own workshop. It is also possible to order drill points according to your own specification. Solines can also assist you with the purchase/delivery of a coupler. This is the connection between the foundation machine and the steel pipe with which the SIP pipes can be drilled away.
