Application Information
Instructions for use

Substrate Preparation

The surface of the concrete substrate shall be sound, clean, dry or wet, and uncontaminated.

This preparation shall be as such as to leave a sound exposed concrete surface free from dust, laitance and any delirious matter.

The gunite surface must not contain broken aggregates. Any leaks shall be sealed with Murex, a water plug mortar, or with Betocryl 60, a Polyurethane injection resin. The surface of the gunite and fine sprayed concrete must be cleaned (no loose stones, nails, wires, etc.).

Application

LOOSELY LAID PVC SHEET INSTALLATION

  1. Install loosely laid PVC sheets over entire area so the light colour is at the visible side towards the substrate.

A. Horizontal Installation:

  1. Install the Geotextile membrane over the entire horizontal area before the PVC
    membrane in full accordance with manufacturer’s method statement
  2. Accurately align sheets and maintain uniform side and end laps of minimum dimensions required. Stagger end laps.
  3. Install the Geotextile membrane as a protection layer over the entire area above the PVC membrane followed by a minimum of 50mm cementitious screed

B. Vertical Applications:

  1. Install the Geotextile membrane over the entire vertical area in full accordance with manufacturer’s method statements
  2. Accurately align sheets and maintain uniform side and end laps of minimum dimensions required.
  3. Install the protection layer of Geotextile membrane above the PVC membrane over the entire area in full accordance with method statement.
  4. Secure top termination of waterproofing with continuous, PVC coated aluminium strip, and a suitable PU sealant as recommended by waterproofing manufacturer.

C. Seam Installation: Hot air welding and end laps of overlapping sheets according to manufacturer's method statement to ensure a watertight seam installation. Inspect outside edge of seams with pointed metal probe and ensure completed laps lay flat through one of the following methods:

  1. Method 1: All seams of installed waterproofing can be subject to pneumatic test at test pressure of 2.00 bars.
  2. Method 2: Testing the welded joint using a vacuum test machine

D. Any hole, resulting from construction activities, noted in installed membrane shall be repaired in accordance with manufacturer’s method statement.

CORNER JOINT INSTALLATION

A. Install corner details in accordance to waterproofing manufacturer's written instructions.

Use same welding system as specified for membrane.

INJECTION HOSE SYSTEM INSTALLATION

A. General: Comply with manufacturer’s printed instructions. The injection system shall be installed by an experienced specialist applicator authorized in writing by manufacturer.

  1. Coordinate with the work of “Cast-in-Place Concrete” for installation of injection system components through concrete elements in basements similar to raft slab, vertical walls and columns.

B. Injection system shall be placed in 8-12 meter lengths with entry port and vent ends terminated using butterfly plastic shutter connectors and shall offer the user the option of flushing and re- injection.

C. Shutter connectors shall be placed in vertical elements adjacent to the joint.

D. The system shall be injected at least once, with the re-swellable injection resin, after completion of wall construction.

Limitation

Do not directly apply the PVC membrane permanently on bitumen and plastics other than PVC, a separation layer of geotextile is required.
