Batimix SBWM 131 (EP/180 Sand, 3mm)

Description

BATIMIX SBWM 131 (EP/180 Sand, 3mm) is an SBS (Styrene Butadiene Styrene) modified, bituminous waterproofing membrane produced in 3mm thickness for general waterproofing applications. Its upper surface and subsurface are coated with PE. It is reinforced with Polyester.

Main Purpose

BATIMIX SBWM 131 (EP/180 Sand, 3mm) 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.

Features

BATIMIX SBWM 131 (EP/180 Sand, 3mm) membrane is characterized by the following:

• Used in single or multilayer systems
• Good high-temperature resistant and low-temperature resistant properties
• Good adaptability to extreme climates
• High tensile strength and tear resistance property. High in ductility and good in dimensional stability
• Strong adaptability to base layers prone to deformation
• Corrosion and ultraviolet radiation resistant
• Good in puncture resistance, cannot be broken easily, has a self-healing property, and is good in aging resistance
• Provides a strong lasting bond
• In situ waterproofing - local application exactly where it's needed
• Excellent alternative for areas with many complex details
• Quick and straightforward to apply
• Water cannot find a track under the membrane, enabling any damage to be traced quickly and repaired easily
• Adheres readily to any sound concrete, brickwork, timber or steel, and will effectively cover corners and any minor surface irregularities or protrusions
• Can be applied at temperatures as low as -50C Excellent low-temperature flexibility and adhesion characteristics
• No on-site curing time required
• When used over construction or bridging joints, there is no need for specific detailing as the membrane is flexible enough to accommodate minor structural movements that are likely to occur
• Has been independently assessed to last the lifetime of the structure

Health and Safety

BATIMIX SBWM 131 (EP/180 Sand, 3mm) is not a hazardous material. For additional information, kindly refer to the product’s Material Safety Data Sheet.

Directions for Use

Preparation of Substrate:

Typically concrete surfaces should be thoroughly swiped of all dirt and construction debris and then cleaned with a blower. Do NOT power wash with water.

All concrete surfaces must be left dry, free of voids, laitance or any other matter that may impair the high bond or performance of the membrane and frost-free. 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 lightly roughened to increase the bond achieved by the membrane.

After cleaning and carrying out 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, BATIMIX SBWM 131 (EP/180 Sand, 3mm) is fixed by torch welding the underside. The application should not proceed during inclement weather. Rain soaked surfaces should be thoroughly dry before the first layer is applied.

Membranes should be installed on all vertical surfaces prior to application on horizontal surfaces. Ensure that when applied, the vertical membrane lap ends on the horizontal surface a minimum 15 cm. Using a squeegee apply the first layer of membrane to the main areas of the substrate to a minimum thickness of 3mm. Allow for 75mm overlaps, taking into account the membranes 1m width.

Ensure there are no air pockets or creases. On the same day apply a second coat of BATIMIX SBWM 131 (EP/180 Sand, 3mm) 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 75mm and sealed with BATIMIX SBWM 131 (EP/180 Sand, 3mm). Once installed the waterproofed area can be accessed by operatives to install subsequent coverings.

Storage

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.
