Over the years we have been asked about using basalt columns as post bases for a variety of supported structures such as: entryways, porches, pergolas, elevated decks, etc. The problem in using natural columns in such applications is you need a really flat bottom, a bore hole to receive some sort of mechanical attachment piece and a flat spot on top to set your post. Our own project spurred some thought and design and we now offer these in a variety of heights. We think they look REALLY cool!
They can also be used as bubbling column water features!
