As GroundPlug^® Twister^TM Foundations come in many different lengths, they are very suitable for installing multi-level decks in a fast and easy way. This is also what homeowner Peter took advantage of when he added a deck to how newly built home. His 753 ft.² large deck project is built in multiple levels, including several steps. Even though Peter’s home is located in an area that can be affected by heavy winds, he feels very safe using GroundPlug^® Twister^TM Screw Piles as a foundation for his deck – and he even used our GroundPlug^® heavy duty anchor kit for the kid´s trampoline as well.
