General Description
"CANLON" Forfens Smooth is polymer pre-applied waterproof membrane, comprised of white polymer sheet (HDPE or TPO), pressure sensitive adhesive, and weather resistant coating layer. The backside factory lap can enhance the installation and significantly improve the overlapping strength. In the more extreme jobsite condition (such as rains, water, low temperature, etc.).
It can also achieve effective connection on factory laps.The installation of the membrane adopts the pre-applied method, which can realize a full bonding with the casted concrete and avoid the 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. MBP Membrane is usable against pressurized water.
- Waterproofing to basements of industrial and civil engineering.
- Pre-applied waterproofing system for walls, tunnels and subways.

Installation
Application-Preparation of the surface
The surface must be sound, even, stable and clean. The substrate to be coated should not have protrusions, gaps, joints or voids greater than 10 mm. To prevent movements of penetrations such as pipe penetrations for water and electricity during concrete and membrane installation, they have to be fixed and stabilized. Damaged concrete should be renovated with MBP Multi Mortar first. Sharp edges have to be removed first.
Material- horizontal application
ForfensMembrane must be placed with the granular adhesive coating layer upwards and the white layer facing the substrate.
The overlapping between the membranes is 75 mm. Before removing the silicone foil(of the overlapping area) ensure that the membranes overlapping edge is positioned correctly. Ensure the back side of each subsequent roll s clean prior to overlapping.
Then start removing of plastic film 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 film 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 film (on the overlapping area)ensure that the membranes overlapping edge is positioned correctly. Ensure the back side of each subsequent roll is clean prior to overlapping.
Then start removing of plastic film 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 film 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 pouring of concrete.
Pouring of concrete
Ensure that all overlapping areas are sealed and the foil 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 and or concrete damage. A minimum concrete compressive strength of 10 N/mm2 recommended prior removing formwork.
