After getting my new bench , I had to make an extended area of my fire pit area. I dug out more grass and added a fountain area and when tufa project is dry it can be installed and flow over into holding pond that was made from a child's 5 foot paddle pond and hid under rocks. The tufa is 24 inches so hopefully I made it strong enough when dry, to sit on the pipe base my DH welded up for me.. I guess if unsure it could have a steel plate under to insure it isn't going to break and fall into the pond, Once the rains are on their way out we can sit back and finally enjoy the sounds of water flowing( not from the skies) , a campfire and view of our back yard retreat with a cool one in hand.
