Problem Evident At Base Of Stairs
The problems with this stone wall were clear at the base of the stairs. Stones were falling from the wall and soil was entering the basement. In many parts of the basement, the walls had been covered with plastic as an added layer of protection but in this exposed area, we can see just how severe the issue is.
Strategic Approach Needed
With stone walls, we not only need a unique approach since the wall can't just be patched with a new block, but existing fixtures like plumping and electrical in the basement create an added level of difficulty in repairing the structure.
Walls Are Exposed
The first step towards preparing the walls was taking the plastic covering off to fully expose the rock walls.
Before the walls are sprayed, framing is constructed at the top of the walls to contain the concrete within the desire area.
Electrical Protected Before Shotcrete
Before we can apply Shotcrete on the wall, electrical panels needed to be moved or protected. We carefully prepared the space so that we could spray around the panel without damaging it or restricting access to it.
Plumbing Pipe Covered
The plumbing pipes were covered with corrugated drainage pipe to protect them from the spray. The drain pipe can be removed easily after the application.
The area at the base of the stairs was crumbling and had stones falling out from the base of it. Now its a strong and smooth surface that provides great support for the home above.
Finished Walls Are More Reliable
The completed product is a strong smooth wall that will reliable support the home for many years to come.
Protective Coverings Removed
The protective coverings over the plumbing pipe were removed. The original pvc is clean and unharmed by the spray.
Electrical Units Unharmed
The electrical units on the wall stayed unharmed during the spray. After the Shotcrete application, we removed the protective covering so that the switches and panels could be easily accessed and maintained once again.
