Application Information

Instructions for use

Application

PVC FLEECE BACK SHEET INSTALLATION (FULLY BONDED SYSTEM)

A. General: Install Fleece back sheets over entire area in full accordance with manufacturer's method statement.

Install membrane so that the PVC is at the visible side and the fleece back is towards the substrate.

B. Horizontal Installation:

Adhere the fleece back PVC membrane (fully bonded) using Neofil S10 adhesive to the entire horizontal area
Accurately align sheets and maintain uniform side and end laps of minimum dimensions required. Stagger end laps.
Install the Geotextile membrane as a protection layer over the entire area above the fleece back PVC membrane followed by a minimum of 50mm cementitious screed

C. Vertical Applications:

Adhere the fleece back PVC membrane (fully bonded) using Neofil S10 adhesive to the entire vertical area
Accurately align sheets and maintain uniform side and end laps of minimum dimensions required. Stagger end laps.
Install the protection layer of Geotextile membrane above the PVC membrane over the entire vertical area in full accordance with manufacturer’s method statement
Secure top termination of waterproofing with continuous, PVC coated aluminium strip, and a suitable PU sealant from Colmef’s joint sealant product range.

C. Seam Installation: Hot air welding and end laps of overlapping sheets according to manufacturer's method statement to ensure a watertight seam installatio Inspect outside edge of seams with pointed metal probe and ensure completed laps lay flat and are free of voids, fish mouths, or wrinkles using one of the following methods:

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

E. 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 according to waterproofing manufacturer's written instructions.

Use the same welding technique as specified for membr

Surface 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 granite 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 granite and fine sprayed concrete must be cleaned (no loose stones, nails, wires, etc.).

Limitation

Do not directly apply the PVC membrane permanently on bitumen and plastics other than PVC, a separation layer of geotextile is required.
The PVC membrane can be exposed to temporary UV light for a period of 6 months
Insuwrap 2000 TNL-FB can be exposed temporary to ground water or polluted water with temperature up to 50°C for 3 months.
