Polyester reinforced atactic polypropylene (APP) modified waterproofing membrane (180 g/m²) in 4 mm thickness with polyethylene film on top.
BATIMIX ABWM 122 (P/180 Plain, 4mm) is ideal for general use in single or multi-layer systems. It is used for waterproofing any concrete or cemented flat surface. It is also used for waterproofing low slope concrete roofs, balconies, car parks, sewage canals, and subgrade structures.

BATIMIX ABWM 122 (P/180 Plain, 4mm) membrane is characterized by the following:
BATIMIX ABWM 122 (P/180 Plain, 4mm) is not a hazardous material. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Preparation of Substrate:
Typically, the cleaning of a concrete surface will start with a thorough sweep of all dirt and construction debris and then cleaning with a blower. Do NOT power wash with water.
All concrete surfaces must be left dry, frost-free, free of voids, laitance, or any other matter that may impair the high bond or performance of the membrane. Contact Holderchem for advice on the effective removal of more difficult contaminants such as form-release agents or curing compounds.
The resultant surface should be uniform and slightly roughened to increase the bond achieved by the membrane.
After cleaning and any necessary repair work the concrete substrate should be primed with a high penetration primer, spray or roller applied. Allow the primer to dry thoroughly. Metal, plywood, and wood boarding need not be primed
Application Method:
After the concrete substrate has been primed, heat the blocks of BATIMIX ABWM 122 (P/180 Plain, 4mm) in a double-lined oil or air type melter and mix slowly. The application should not proceed during inclement weather and rain-soaked surfaces should be thoroughly dry before the first layer is applied.
The membrane should be installed on all the vertical surfaces prior to application of the horizontal surfaces. Ensure that when applied the material is returned onto the flat by a minimum of 150mm. Using a squeegee apply the first layer of membrane to the main areas of the substrate to a minimum thickness of 3mm. Work to a bay size of approximately 1m wide but allow to extend this to accommodate the 75mm overlap. Ensure there are no air pockets or creases.
On the same day apply a second coat of BATIMIX ABWM 122 (P/180 Plain, 4mm) to a minimum thickness of 3mm fully encapsulating the fabric reinforcement within the membrane.
A protection sheet should then be brush-rolled into the membrane surface as quickly as possible while it is still tacky and warm. All protection sheet edges should overlap by a minimum of 75mm and be sealed with BATIMIX ABWM 122 (P/180 Plain, 4mm). Once installed the waterproofed area can be accessed by operatives to install the subsequent coverings.

Storage Guidelines: Store in a dry, cool environment in a shaded, well-ventilated area. Avoid direct sunlight and high temperatures to prevent deformation or premature aging. Store rolls vertically on end to prevent flattening or deformation. Avoid stacking rolls horizontally.
Keep materials covered and protected from rain, snow, and UV rays. Store in enclosed spaces if outdoor storage is necessary. The ideal storage temperature is typically between 5°C and 30°C (41°F – 86°F).
Avoid storing below freezing temperatures, especially if membranes have self-adhesive layers. Do not stack heavy objects on top of the rolls. Ensure the surface is flat and stable to prevent tipping or damage.
Handling Guidelines: Use Caution When Lifting. Use proper lifting techniques or mechanical equipment. Bituminous rolls can be heavy and awkward to carry.
Inspect Before Use: Check for damage, deformation, or contamination before application. Damaged rolls should not be used and must be reported or replaced.
Protect the Edges: Handle rolls carefully to avoid damaging the edges, critical for overlap and sealing.
Avoid Contaminants: Keep membranes away from oils, solvents, and chemicals that could degrade the bitumen. Use older stock first to avoid aging or expiry of materials.
Safety Notes: Follow PPE guidelines (gloves, safety boots, etc.). If using torched membranes, handle with fire safety precautions in place. Be cautious of fumes when heating bituminous products.
