CANLON brand MBP Pro Pre-applied Waterproofing Membrane, composed of white polymer sheet (HDPE or TPO), pressure-sensitive adhesive, and weather-resistant granular layer on the upper surface, is specifically developed to elevate the construction and application performance of below-grade waterproofing. Designed with an adhesive selvage on one side, and a layer of back-coated selvage on the other side, it realizes an adhesive-to-adhesive bond on selvage overlaps, which enhances the installation applicability and significantly improves the overlapping strength. Even in harsh job site conditions (such as rain, water, low temperature, etc.), it still achieves effective connection between membranes.
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.
MBP Pro Pre-applied Waterproofing Membrane is used for the waterproofing of exterior basement walls, foundations, floor plates, etc. The same product is suitable for vertical and horizontal areas and usable against pressurized water.
·White sheet with non-recycled HDPE or TPO(pellets) as raw materials --easy to identify whether or not to add inferior recycled materials.
·Resistant to weather conditions--the specially formulated surface coating ensures that self-adhesive properties withstand up to 49 days of UV exposure, rainwater, dirt contaminants, etc.
·Good dimensional stability-- dimensional variation rate does not exceed 0.5%, with smaller wrinkles compared to similar products.
·Resistant against impact and puncture, effectively reduces the possibility of membrane being destroyed during construction.
·High resistance to chemicals such as acid, alkali, and salt, protect the membranes in most areas of alkaline land or acid rain.
·MBP Pro Pre-applied Waterproofing Membranes unaffected by wet jobsite conditions--effective overlapping can be realized in the water.
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
MBP-Pro Pre-applied Waterproofing Membrane must be placed with weather 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 selvage) ensure that the membrane's overlapping selvage is positioned correctly and the underside of the succeeding sheet is clean before 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
MBP-Pro Pre-applied Waterproofing 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 selvage) ensure that the membrane's overlapping selvage is positioned correctly and the underside of the succeeding sheet is clean before 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.
End laps overlapping
For the butt joint of end laps, apply MST Detail Strip centered over the center of the butt joint with the adhesive surface facing up and rolling firmly. For overlapping the end laps, apply MST Double Side Tape centered over the edge of the overlap and ensure the tape is rolled firmly.
Repairs before concrete placement
If the MBP-Pro membrane is damaged during the installation of formwork and reinforcement steel placement, repair damage can be done by applying the MST sanded tape centered over the damaged area before the concrete pour. Apply PUS Polyurethane Sealant for sealing around penetrations, and joint processing such as expansion joints.
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 the pouring of concrete.
Formwork removal
It is essential not to remove formwork until the concrete has sufficient compressive strength to develop the required adhesion with MBP-Pro Membrane. Too early removal of all formworks can lead to a displacement of MBP Pro Pre-applied Waterproofing Membrane or concrete damage. A minimum concrete compressive strength of 10N/mm2 is recommended prior to removing the formwork.
