GroundPlug® SK/GP
Strong foundation for pylons and masts
GROUNDPLUG® SK/GP IS AN IDEAL SOLUTION FOR FOUNDATIONS WHERE THERE IS BOTH A HIGH TENSILE/COMPRESSIVE LOAD AND DISPLACEMENT.
This foundation, specially designed for masts, pylons and similar structures, is available in two versions: the GroundPlug® SK foundation with anchoring shovel and the GroundPlug® GP foundation without shovel, but with the same design as the SK products. The shovel is used when extra tensile load capacity is required.

STANDARDISED PRODUCTS
GroundPlug® offers 7 standard versions of GroundPlug® SK and GP foundations with torque capacities ranging from 9 kNm to 99 kNm.
Universal Foundation
The universal GroundPlug® SK and GP foundations are suitable for absorbing displacement, torque, and vertical pressure and traction.
Capacity As Needed
We supply nine standard types of GroundPlug® SK and GP foundations with capacities ranging from 9 kNm to 99 kNm. In addition, customised solutions for individual GroundPlug® SK and GP foundations can be supplied with capacities of up to 190 kNm.

Flexible Adaptation
The capacity of the GroundPlug® GP foundation can be increased by installing a shovel system that opens up in the ground once the foundation has been installed. The foundation with the shovel system is called the GroundPlug® SK foundation.
Different Areas of Focus
GroundPlug® SK and GP foundations are primarily used for lighting, street furniture, road signs for the Danish Road Directorate and signs for Banedanmark.
INSTALLATION
Single GroundPlug® SK or GP foundations are mainly used for large signage, commercial signs, lighting installations, flagpoles and street furniture.

DOCUMENTATION
ALL STEEL FOUNDATIONS FROM GROUNDPLUG® ARE BASED ON CALCULATIONS IN ACCORDANCE WITH:
EN 1990, EN 1991-1-1, EN 1991-1-3, EN 1991-1-4,EN 1991-2, EN 1993-1-1, EN 1993-1-3, EN, 1993-1-5, EN 1993-1-8, EN 1993-1-9, EN 1993-5, EN 1997-1,EN 1997-2, EN 1794-1.
ANALYTICAL CALCULATIONS AND PRACTICAL TESTS:
- ASTM Standard Designation (ASTMD1143, ASTM D3689, ASTM D3966) of pressure, tension and horizontal load on single screw foundations. Performed by Applied Foundation Testing (AFT), USA, and CLTTHOMPSON INC, USA.
- NIRAS capacity and soil calculations, verified by LPILE by Ensoft Inc.
Our engineering team can provide design documentation for any structure based on European Design Standards (Eurocodes 0-9) and national annexes. Calculations can also be based on applicable American and Australian Design Standards.
