Platon Foundation Wrap Installation

• How to Install

  Note: Platon Foundation Waterproofing must be used in conjunction with a foundation footing drain.
  
  
  1. Break off all ties and projections on the wall and clear stone and debris from the footing. Seal tie rod holes with mastic. ICF walls do not need any surface preparation. Parge block walls.
  2. Chalk a line at finished grade around the entire foundation and run a generous bead of caulking 25mm (1") below the line.
  3. Working from left to right, unroll the membrane along the foundation, dimples toward the wall, smooth tab at the top, following the chalk line. Keep the smooth tab tight to the wall. Platon must wrap the foundation from a point directly touching the top of the footing up to finished grade or ground level. If the height of the roll permits, Platon can be creased sharply at the foundation/footing joint and brought out over the footing.
  4. Fasten with Speedclips along the top of the membrane. The Speedclip dimples mesh with the top 2 rows of Platon dimples and the Speedclip offset presses the smooth tab tight to the wall. Nail (or screw on ICFs) through the small centre hole between dimples. ALTERNATIVELY, fasten with Platon Plugs and nails in the second and third row of dimples, spaced 20cm to 30cm (8" to 12") apart. Secure the smooth tab with nails and Platon Moulding strips along the top of the tab. Note: Clay soil requires additional Plugs in the fifth row of dimples (not required with Speedclips).

• Corners

  Bend and crease the membrane to provide the best fit. If extending Platon over the footing, make a small cut at the bottom corner, to facilitate a good fit.

• Joints

  For vertical joints between rolls, overlap a minimum of 51cm (20"). Any water that gets into the joint will flow to the footing drain before it gets to the wall. Horizontal joints, if required, should be overlapped by 5 dimples, with the upper course over the lower one.

• Windows

  Cut the Platon membrane flush with the side and 8cm (3") lower than the window opening. If using Speedclips, move the cutout piece down to seal the open horizontal cut, mesh the dimples and fasten with Speedclips. If using Platon Plugs, continue the nailing pattern below the window opening and seal the open horizontal cut with Platon moulding. The window well is installed over the membrane, which can then be trimmed and caulked.

• Sloped Grades

  For a gradual slope, measure the grade change chalk line length, add 51cm (20") for joint overlap and cut that length of Platon. Install with the smooth tab following the chalk line, fasten with Speedclips or Platon Plugs and Moulding, and trim along the edge of the footing. For a steep slope, cut the membrane to match finished grade and seal the open edge with caulk and Platon Moulding. Tip: Install Platon on the lowest elevation first, then the sloped grade, then the higher elevations.

• Backfilling

  Clear stone must be placed over the footing drain and extended over the footing against the base of the Platon in accordance with local building codes. Backfill carefully. Do not permit machinery, large rocks or frozen clumps to impact the Platon.

• Tear Repair

  Caulk around the tear. Apply a 24" wide patch of Platon over the tear, meshing the dimples, and fasten with Speedclips or Platon Plugs.

• Pipe Projections

  The pipe must be sealed to the foundation with hydraulic cement before Platon is installed. Split Platon vertically from the pipe to either top or bottom. Cut Platon snug around the pipe. Caulk around the pipe and both sides of the split. Apply a 24" wide patch of Platon over the split and fasten with Speedclips or Plugs.

• Flood Boot

  Must be installed prior to installing Platon when: (1) a high water table is encountered, (2) footing drain is placed on top of the footing, (3) floor slab is level with, rather than on top of, the footing, or (4) on any horizontal below grade step in the foundation such as a buried brick ledge. Apply a “peel and stick” or rubberized liquid waterproofing to cover the footing (or brick ledge) and wall to a point 12" higher than the anticipated water table.

• What You Need

  Platon Membrane	One roll for every 19m (62 lineal feet) of foundation (allows for joint overlap). Membrane can be overlapped horizontally by 15cm (6") for deep foundations.
  Platon Speedclips OR Platon Plugs and Moulding	65 Speedclips per roll of membrane (Speedclips secure the membrane AND press the smooth tab tight to the wall). OR 1 bag of Platon Plugs per 3 rolls of membrane and 10 strips of Platon Moulding per roll.
  Platon Moulding Strips	At least 4 strips per job PLUS 1 strip per window well.
  Caulking	Minimum 2 tubes per roll. For concrete or wood foundations, use butyl rubber or asphalt-based roof cement. For insulated concrete forms (ICF), use PL300 foam panel adhesive. DO NOT USE SILICONE, LATEX OR POLYURETHANE.
  Fasteners	For concrete, use 32mm (1-1/4") concrete nails. Power nail gun for block or poured walls. For ICF or wood foundations, use 38mm (1-1/2") drywall or corrosion-resistant deck screws.
