The home feature two expansive walls - 15x20' and 25x30' - made of black absolute granite - an expensive material - and travertine stone, neither of which met the designer's conceptual vision. His first thought was to use ARDX grey concrete, but this option was not feasible due to the product's thickness.
Complete demolition was another option, but a costly and time-consuming one, requiring the following:
- Architectural/engineering drawings for permits (estimated time 10 days)
- Check approval (up to 2-3 weeks)
- Stone removal (estimated 2 weeks)
- Stud replacement (estimated 3 weeks) as needed
- Cement board installation (estimated 1 week)
- Waterproof membrane installation (estimated 4 days)
- Stone installation (estimated 2 weeks)
- Inspections, municipal approval, HOA approval (3-5 weeks)
- Constraints of removal of demolition debris due to location of property on narrow winding mountain road.
With a projected demolition timeline of 12-15 weeks, this option was quickly abandoned.
The engineers faced three main challenges with this residential renovation:
Challenge 1: Creating a consistent surface on immense 25 foot walls
Solution: Using a scaffolding with three men on top, three in the middle, and three on the bottom allowed the applicators to apply smooth, even coats of X-Bond.
