What we do

Shower waterproofing, done by people who do nothing else. We leave demolition and tile to the people who do them best.

The pan, in cross-section

What is under your tile

Every hot mop pan is built in the same order. This is what goes in, and what has to be ready before we start.

Cross-section of a hot mop shower pan A side view of a shower pan. Blocking stands behind the wall and a curb closes the front. A cement pre-slope drops toward the drain. Hot tar and felt are mopped over it in layers and turned up the walls and over the curb, with yellow fiberglass mesh in the corners. Water stands in the finished pan for the flood test. 1 2 3 4 5 6 7 BlockingCurbDrainPre-slopeTar and feltMeshFlood test

  1. 1

    Blocking

    Around the walls, typically 2x10 or 2x12. It has to be in before we start.

  2. 2

    Curb

    Also called the dam or threshold. A minimum of two 2x4s; three is recommended.

  3. 3

    Drain

    Set and flushed before we start. It has to be the correct shower drain.

  4. 4

    Cement pre-slope

    Laid so all of the water drains toward the drain.

  5. 5

    Hot tar and felt

    Hot tar mopped on in layers with a fiberglass mop, with perforated felt between the layers.

  6. 6

    Fiberglass mesh

    Yellow mesh in the corners and seams so they hold up longer.

  7. 7

    Flood test

    Water goes in to prove the pan holds. Then your tile setter sets the tile over it.

What has to be ready before we start

  • The drain is set and flushed.
  • Blocking is installed around the walls, typically 2x10 or 2x12.
  • The curb (also called the dam or threshold) is in place: a minimum of two 2x4s, and three is recommended.
  • The shower floor is solid. If it moves or feels like it could give way underfoot, we cannot mop it. Hot mop is heavy.
  • The correct shower drain is installed.
  • Demolition is finished. We do not demo.

What we do not do

Demolition. It is normally done before we are called.

Tile work. Your tile setter sets the tile over our pan.
