Product Description

General Description
CANLON brand Forfens smooth membrane is composed of white polymer sheet (HDPE or TPO), pressure sensitive adhesive, and weather resistant coating layer. This unique coating layer is a developed organic chemical, which can react with the post-cast concrete as it cures so as to form an effective bonding between the membrane and the concrete. Meanwhile, the coating layer is anti-stick as well as effectively protects the pressure sensitive adhesive layer.
The self-adhesive membrane with back-coated selvedge can enhance installation applicability and significantly improve overlapping strength. Effective connections on selvedge overlaps can also be achieved in harsh jobsite conditions(such as rain, water, low temperature, etc.).The installation of membrane adopts the pre-applied method, which can realize full bonding with the post-cast concrete and prevent water migration.

Application
Applied either horizontally to smoothly prepared concrete substrate and compacted earth or crushed stone substrate; or vertically to permanent formwork. Concrete is then cast directly against the adhesive side of the membranes.
Forfens Smooth Membrane is used for the waterproofing of exterior basement walls, foundations, floor plates, etc.The same product is suitable for vertical and horizontal areas. Forfens Membrane is usable against pressurized water.
 

• Waterproofing to basements of industrial and civil engineering.
• Pre-applied waterproofing system for walls, open-cut tunnels and subways.
   

Advantages
1.White sheet with non-recycled HDPE or TPO(pellets) as raw materials --easy to identify whether or not add inferior recycled materials.
2.Pressure sensitive adhesive with excellent physical properties of initial adhesion, cohesive force and peel strength.
3.Resistant to weather conditions--the specially formulated surface coating ensures that self-adhesive properties withstand up to 49 days of UV exposure, rain water, dirt and contaminants, etc.
4.Good dimensional stability-- dimensional variation rate does not exceed 0.5%, with smaller wrinkles comparing to similar products.
5.Resistant against impact and puncture, effectively reduces the possibility of membrane being destroyed during installation.
6.High resistance to chemicals such as acid, alkali and salt, protect the membranes in most areas of alkaline land or acid rain.
7.Membranes unaffected by wet jobsite conditions--effective overlapping can be realized in the water.

 Installation
Substrate preparation
The surface must be sound, even, stable and clean with no protrusions, gaps, joints or voids greater than 10 mm. To prevent movements of penetrations such as pipe penetrations for water and electricity during concrete pour and membrane installation, they have to be fixed and stabilized. Damaged concrete should be renovated with MBP Multi Mortar and sharp edges be removed first.
Material- horizontal application
Forfens Membrane must be placed with weather resistant coating layer facing the concrete pour and the white polymer sheet facing the substrate.
The overlapping between the membranes is 75 mm. Before removing the plastic release liner (on adhesive selvedge) ensure that the membrane's overlapping selvedge is positioned correctly and the underside of the succeeding sheet clean prior to overlapping.
Then start removing of plastic release liner to bond the membranes together. Use a heavy roller to ensure a complete perfect bonding between the membranes. Then go ahead with removing of plastic release liner and press membranes together.
Material-vertical application
Forfens Membrane must be fixed mechanically to the substrate by using fixing tools. These fixings must have a low profile head so that the membrane won't be damaged from the fixings.
The overlapping between the membranes is 75 mm. Before removing the plastic release liner (on adhesive selvedge) ensure that the membrane's overlapping selvedge is positioned correctly and the underside of the succeeding sheet clean prior to overlapping.
Then start removing of plastic release liner to bond the membranes together. Use a heavy roller to ensure a complete perfect bonding between the membranes. Then go ahead with removing of plastic release liner and press membranes together.
Repairs before concrete placement
In case of damaging the Forfens Membrane during installation of formwork and reinforcement steel placement it is necessary to repair prior to the concrete pour.
Pouring of concrete
Ensure that all overlapping areas are sealed and the release liner is removed in that area. Do not damage the membrane during pouring of concrete.
Formwork removal
It is very important not to remove formwork until the concrete has sufficient compressive strength to develop the required adhesion with Forfens Membrane. Too early removal of all formworks can lead to a displacement of Forfens Membrane or concrete damage. A minimum concrete compressive strength of 10 N/mm2 recommended prior to removing formwork.
