※ Construction Methods

BAC Double-sided Self Adhesive Bituminous Waterproofing Membrane can use construction methods as below: Wet Application, Hot Application, Dry Application.

1. Wet Application

Wet Application is to use cement paste or cement mortar as bonding material to bond the membrane with the base course. This invention is a huge renovation for the waterproof industry. It not only reduces the requirements for the base course during the construction of waterproof membrane, but also greatly improves the bonding effect.

Description of cement mortar used in wet application:

The water-cement ratio is between 0.35 and 0.4, the thickness of the coating on the base is controlled in 3-5mm. Note that the base surface needs to be wet with water first (wet, no visible water), then scratched cement mortar. During the paving of membrane, we should pay attention to exhaust the air, so that the membrane and cement mortar can be completely bonded with each other.

 

 

2. Hot Application

HOT APPLICATION is composite of rubber asphalt waterproof coating and self-adhesive membrane which is closely bonded with the base layer to form a "skin-type" waterproof system. It is an organic whole with complementary advantages, which can adapt to the deformation and self-healing performance of the base, effectively prevent water channeling and reduce leakage hazards.

Substrate Requirements

1) The firmness and strength of the base layer should meet the design requirements.

2) The surface of the base layer should be clean and smooth, and there should be no quality defects such as powdering, sanding, peeling, voids and pits.

3) Remove sundries, greasy dirt, sand, etc. on the surface of the base layer, and the cleaning work must be carried out at any time during the construction.

4) If there is clear water on the base layer, it needs to be cleaned before construction. If the base surface is relatively damp, it needs to be dried with a blower.

3. Hot Application

If the substrate condition can meet with designed and standard requirements, flat, even, dry and without dirties, after covering the base surface with primer, the membranes can be paved directly. Al l pipe fitting should be pre-covered as designed and standard requirements, and to be seal treated. The internal and external corners of substrate wipe to circular. The min radius of internal corners is 50mm and the max radius of external is 20mm. 

Make sure the moisture content less than 9% (Dry test: pave 1㎡ waterproofing bitumen sheet smoothly on the screed-coat, then check the flat roof self adhesive membrane paved side whether has watermark or not after 3~4 hours, if not, it can be constructed).

※   Storage and Transport

 

1. Different types or specifications of products should be separated, not mixed.

2. Keep it dry and ventilated, protected from the sun or rain.

3. Storage temperature should not be higher than 45 ℃. Pile up the membranes flatwise whose stockpile height should not exceed five layers.

4. Prevent tilt or side pressure during transportation, and cover with felt if necessary.

5. Storage time is at least one year from manufacture date if the product is under normal storage condition.

Self adhesive bituminous waterproofing membrane is a high-performance, cold-applied waterproofing material designed to provide long-lasting protection for building foundations, roofs, basements, tunnels, bridges, and various civil engineering projects. It is composed of a premium bitumen compound modified with high-quality polymers and reinforced with a durable carrier layer, such as cross-laminated polyethylene film, aluminum foil, or polyester. The membrane is covered with a self-adhesive layer that allows easy application without the need for heating or open flames, ensuring safe, efficient, and clean installation in all construction environments.

This waterproofing solution integrates advanced polymer-modified bitumen technology that provides excellent elasticity, adhesion, and resistance to environmental stress. The self-adhesive layer is protected by a silicone release film, which can be easily peeled off during installation, ensuring a secure bond with concrete, metal, or masonry substrates. Its outstanding water resistance, flexibility, and mechanical strength make it ideal for both new construction and renovation projects.

One of the most significant advantages of self adhesive bituminous waterproofing membranes is the simplicity of installation. Unlike traditional torch-applied membranes, it does not require any heating equipment, which eliminates fire hazards and reduces labor time. Workers can simply unroll the membrane, peel away the release liner, and press it onto the prepared surface. This not only accelerates project schedules but also ensures uniform adhesion and seamless waterproofing coverage. Its cold application method makes it especially suitable for confined or flammable environments, such as wooden structures or enclosed basements.

The bituminous layer of the membrane is formulated using SBS (Styrene-Butadiene-Styrene) or APP (Atactic Polypropylene) modified bitumen, offering outstanding flexibility at low temperatures and excellent flow resistance at high temperatures. This ensures reliable performance across a wide range of climates, from cold northern regions to hot and humid tropical areas. The polymer modification also enhances UV resistance, aging resistance, and mechanical stability, ensuring a long service life of up to 20 years or more when properly installed and maintained.

In addition to waterproofing performance, the membrane provides excellent self-sealing capability. When punctured by nails or minor mechanical damage, the bituminous material can flow slightly to close the hole, preventing leakage. This self-healing characteristic makes it particularly effective for complex construction details such as corners, joints, and pipe penetrations.

Self adhesive bituminous waterproofing membranes are available in a variety of thicknesses, typically ranging from 1.2 mm to 4.0 mm, depending on the project requirements. They can be supplied with different surface finishes — such as sand, polyethylene film, or aluminum foil — to suit various applications. For example, aluminum foil-faced membranes are ideal for exposed roofing systems due to their high reflectivity and UV protection, while polyethylene film-faced types are commonly used for underground structures, retaining walls, and foundations.

The membrane’s adhesion performance is one of its key advantages. The specially formulated self-adhesive layer ensures strong bonding with substrates even on slightly damp surfaces. However, for best results, surfaces should be clean, smooth, and free of dust, oil, or loose materials. A compatible primer can be applied to improve adhesion on porous or uneven substrates. The membrane overlaps should typically be between 50 to 100 mm, depending on project specifications, ensuring continuous and watertight protection.

In terms of mechanical strength, the reinforced carrier layer provides excellent tensile strength, tear resistance, and dimensional stability. This allows the membrane to withstand ground movements, settlement, or thermal expansion without cracking or delamination. The combination of strength and flexibility makes it an ideal choice for structures exposed to mechanical stress or vibration, such as bridges, tunnels, and underground parking structures.

Another key benefit of self adhesive bituminous waterproofing membrane is its environmental friendliness. The cold-applied installation process produces no smoke, odor, or fire hazard, reducing pollution and improving worker safety. Many manufacturers also offer solvent-free or low-VOC formulations that comply with modern green building standards. This makes the product suitable for projects requiring sustainable construction materials and eco-friendly practices.

When used on roofs, the membrane offers outstanding weathering resistance. Its bituminous composition provides long-term durability against rain, snow, and ultraviolet exposure. The top surface can also be overlaid with protective materials such as gravel, tiles, or green roofing systems for enhanced performance and aesthetic appeal. For below-grade applications, the membrane effectively prevents groundwater infiltration, protecting structural integrity and preventing issues such as mold, corrosion, or concrete deterioration.

Maintenance of self adhesive bituminous waterproofing membranes is minimal. Once installed, the system provides continuous protection with little need for repairs. In case of localized damage, repair can be done easily by cleaning the affected area, applying primer if necessary, and patching with a new piece of membrane. The compatibility between old and new membranes ensures seamless integration and restored waterproofing performance.

From a cost-performance perspective, this product provides an excellent balance between affordability and durability. Compared with liquid-applied membranes or torch-on systems, it offers lower installation costs, faster application speed, and reduced risk of installation errors. The long service life and minimal maintenance further reduce total lifecycle costs, making it a preferred solution for contractors, engineers, and project owners worldwide.

In modern construction, self adhesive bituminous waterproofing membrane is widely used in:

• Roofing systems — both flat and sloped roofs for residential, commercial, and industrial buildings.

• Basements and foundations — preventing water ingress and dampness in underground structures.

• Tunnels and subways — providing durable waterproof protection under continuous hydrostatic pressure.

• Bridges and viaducts — protecting concrete decks from water, salt, and chemical corrosion.

• Bathrooms, kitchens, and balconies — offering an effective barrier in wet areas of buildings.

In conclusion, the self adhesive bituminous waterproofing membrane is a modern, high-performance waterproofing material that combines the best properties of polymer-modified bitumen with advanced self-adhesive technology. Its ease of application, superior adhesion, flexibility, and environmental safety make it a reliable choice for a wide range of waterproofing needs. Whether for new construction or renovation, above-ground or below-grade, this membrane ensures long-term durability, watertight integrity, and peace of mind for builders and property owners alike.
