Podcast Episode 135: Rotunda, Revisited
Scary rotunda framing job, preferred shower waterproofing systems, and widening a concrete stoop to support a roof
Justin, Matt, and Patrick field a follow-up question on a particularly frightening rotunda framing job and discuss options for building a round structure from straight joists. Other topics include preferred shower waterproofing systems and strategies for widening a concrete stoop to support the columns of a new portico roof.
Question 1: Rotunda, part 2
Vincent writes: Just following up on the project I had where I needed to re-secure an existing intermittent second-floor exterior deck level to two-story wood stave columns.
So here’s the next issue with the same project. How to reframe the curved edges of the deck of the existing rotunda/gazebo. The existing curved edge of the decking is composed of layer upon layer of what appears to be wood scraps to generate the radius. The problem is that these wood scraps are also what the structural columns rest on, and now everything is slowly sliding off the deck. I’m attaching my engineered solution, basically a ladder with a curved edge laid on the flat, which will combat the overturning moment that the curved edge would naturally want to do. The main beams will be resting on the existing peanut stone columns with these ladder edges attached to either side to recreate the radius. The temporary lally column underneath the deck will be removed once all the new structure is in place. I wanted to get your take as builders if I am overthinking things.
Question 2: Waterproofing a shower
George writes: I am planning to update my bathroom shower from a Bathfitters retrofit to curbless tile with a linear drain at the entrance to the shower. Are Schluter Systems and Kerdi-Board simple enough for a handy homeowner to use for such a project? Can I learn enough from their online tutorials to get the job done, or should I ask my tile supplier to get me into one of their installation seminars?

I am looking to get a portico installed over my front entry. The stoop is 6 ft. wide by 4 ft. deep. I don’t plan on using it as a porch since we have a nice big back deck, but I have a feeling that it may not be wide enough, causing the portico to possibly look too small for the house. The portico posts may also be sitting directly in front of the sidelites as well. I’m thinking that the stoop may need to be widened by 2 ft. (1 ft. on each side).
The stoop is of the precast type sitting on a footer that is tied into the house footer. Also, there are granite treads lying on two of the steps in addition to two additional poured-concrete steps. Removing the old stoop would require a complete rework of the steps.
What options are there to widening it without removing and replacing the stoop entirely?
