- Separation between the wall and floor tiles causes the concrete under the floor tiles to become saturated with water, rotting older pans and forcing water to leak out
- Grout missing around the drain.
- A poorly constructed pan that has no pre-slope to the drain before it is put in place. Usually the weep holes to the drain are clogged.
- Loose floor tiles inside the shower.
- Inside the upper portion of the drainpipe, excessive hair in the drain can cause water to backup into certain parts of the drain. Water flows through where the drain sandwiches the pan and gives the appearance as if the pipe were leaking.
- Similar to #5 (without the hair.) The pan disintegrates where the drain sandwiches the pan due to excessive water buildup in the concrete under the tile floor. It's also possible on newer showers that the pan is not properly adhered where the drain sandwiches the pan.
- If the shower walls are constructed out of Sheetrock or concrete backer board, and the floor is built with traditional wire lath and cement, a setup like this usually cannot handle the stress of movement. Joints will crack and water will saturate the concrete under the tile floor.
- Normal building movement, even the vibration of opening and closing doors can cause cracking problems.
My BIO made simple:
I started my original business doing tile repair and restoration. This meant devoting many years to regrouting and restoration. I also became an expert working with silicone, urethanes and epoxy. Examine how I was able to fill extemely large gaps between the tile and the bathtub with silicone making the joints perfectly flush. BATHTUB PICTURES
As time evolved I reverse engineered problems relating to why shower pans leaked. I spent many years perfecting my techniques. I discovered how crucial it is for showers to have expansion joints and yet it's always overlooked. My web site is loaded with lots of useful information. ENJOY!
