Wondercap Kit Installation Steps (Pre Concrete Puddle Flange)

  1. Cut drainage riser so that the Wondercap flange (1) is 10mm below the desired slab level – allow for a positive fall to shower and floor wastes. Note: Allow 60mm below the top of the Wondercap flange (1) to the pipe riser.
  2. Clean, prime and solvent weld the flange tail to the drainage pipe.
  3. Ensure the foam ring is around base (2) and set in the flange (1) prior to concrete slab pour. Step 3. PRO TIP! - The Wondercap Kit can be used as a reference point / gradient for trowelling to suit the grade required in wet areas.
  4. Pour concrete slab and screed a smooth fall to the Wondercap.
  5. Clean the top of the flange (1) with a damp sponge for waterproofing membrane adherence.
  6. Clean and prepare the surface ready for waterproofing and remove the base (2) and foam ring from the flange (1) and set aside
  7. Apply the waterproofing membrane as per manufacturer’s instructions and requirements
  8. Clean and prepare the surface ready for waterproofing and remove the base (2) and foam ring from the flange (1) and set aside. Step 8. WARNING: DO NOT APPLY WATERPROOFING MEMBRANE DOWN DRAINAGE PIPE.
  9. Reinsert the base (2) into position once the waterproofing has been completed.
  10. Raise the base to the desired tile height and secure into position with bedding mix.
  11. Screed and tile using the Wondercap base (2) as a reference point / gradient. Simply screed up to base (2).
  12. Apply grout and remove the cap (3) from the base 2). PRO TIP! – if you have not allowed for the tile thickness, continue tiling to the floor waste. The tiles will finish 10mm above the top of the base & cap. Remove the cap and simply cut the internal edge of the cap to the height required and insert the spacer ring into the base to support the tile grate and finish flush with the tiles.
  13. Install the grate and secure with grout.
Retro Kit

Retro Kit Installation Steps

  1. Grind a 3mm deep x 50mm wide recess around the drainage pipe for best results.
  2. Cut the drainage pipe to slab level.
  3. Clean, prime and solvent weld the flange (1) tail into the drainage pipe.
  4. If required, the retro flange (1) can be screwed into place with green plugs and counter-sunk screws.
  5. Clean and prepare the surface ready for waterproofing and remove base (2) from flange (1) and set aside.
  6. Apply the waterproofing membrane as per manufacturer’s instructions and requirements.
  7. Apply the waterproofing membrane to as required to wet areas. Finish the waterproofing membrane up to the dotted line indicated on the flange (1). WARNING: DO NOT APPLY THE WATERPROOFING MEMBRANE DOWN DRAINAGE PIPE
  8. Reinsert the base (2) into position once the waterproofing has been completed.
  9. Raise the base to the desired tile height and secure into position with bedding mix.
  10. Screed and tile using the Wondercap base (2) as a reference point / gradient. Simply screed up to base (2)
  11. Apply grout and remove the cap (3) from the base (2). Step 12. PRO TIP! – if you have not allowed for the tile thickness, continue tiling to the floor waste. The tiles will finish 10mm above the top of the base & cap. Remove the cap and simply cut the internal edge of the cap to the height required and insert the spacer ring into the base to support the tile grate and finish flush with the tiles.
  12. Install the grate and secure with grout
Balcony Kit

Quick Install

Balcony Kit Installation Steps

  1. Cut drainage pipe so that the Wondercap flange is 10mm below the desired level of the floor waste.
  2. Clean, prime and solvent weld the 50mm balcony flange tail to outlet pipe as required.
  3. Ensure the foam ring is around base and set in the flange prior to concrete slab pour.
  4. Tie off the balcony outlet to rebars using any of the available attachment points. The outlet has been designed to fit between two layers of engineered balcony steel reinforced bars. It will sit 25mm above the rebar.
  5. The balcony outlet can be connected to either the internal plumbing (stormwater / downpipe) or an external 50mm frog-mouth.
  6. Pour concrete slab and screed a smooth fall to the Wondercap.
  7. Clean the top of the flange with a damp sponge for waterproofing membrane adherence.
  8. Clean and prepare the surface ready for waterproofing and remove the base and foam ring from the flange and set aside.
  9. Apply the waterproofing membrane as per manufacturer’s instructions and requirements
  10. Apply the waterproofing membrane as required to wet areas. Finish the waterproofing membrane over the lip of the flange (1) and into the recess.
  11. Insert and raise the base to the desired tile height and secure into position with bedding mix to support the underside lip of the base.
  12. Screed and tile using the Wondercap base as a reference point / gradient. Simply screed up to base.

  13. Apply grout and remove the cap from the base.

    PRO TIP! – The Wondercap lid/cap can be used in multiple ways to assist you in your tiling.

    The cap can be used as a template for cutting tiles for round grates.The cap can be used as a spacer ring to support the grate to the height of the tiles by simply cutting off the internal ring of the cap to suit.The cap can be used to cap off the 100mm pipe rider if required.
