PROOF that Pre-Slope Works! - Tile Coach Episode 19

A video demonstration, showing proof that Pre-slope on a shower pan works! Some argue that a pre-slope, or pre-pitch, underneath the waterproofing membrane for tile is unnecessary. This video sets out to prove that the pre-slope is an essential step in ensuring the proper function of a traditional type tile shower pan made with a pvc liner or hot mop. The results were astonishing! when using this method, approximately 99% of the water that entered the pan system, exited out of the weep holes within minutes. Upon further investigation, parts of the mortar were broken away to reveal that only small droplets were left on the pan liner itself. To see how I built my demonstration shower floor for tile, you will need to watch other videos that explain in detail how I did each step.
