Ground Sun were commissioned to install screw pile foundations using handheld machinery for this temporary walkway to allow access over the back garden for a basement excavation and extension for a large house in north London. Screw pile foundations were necessary due to the number of protected trees in the area. Once constructed and works are completed Ground Sun are also contracted to remove the piles by simply unscrewing them and reinstalling them in a new position to provide permanent foundations for decking and recreational use.
