Product Description

Bondsure™ Membrane Series

Bondsure® S-CLF Super Cross Laminated Film Self-adhesive Bituminous Waterproofing Membrane is a kind of self-adhesive waterproof rolling material composed of imported super cross-laminated film, self-adhesive rubber asphalt adhesive material with high performance formula, anti-adhesive layer & isolation film, with stronger tensile strength, elongation and tear resistance, and has excellent UV resistance and stability.

Types:

1) Pre-applied Type: YC Type(Pre-laid with sand surface)

2) Self-adhesive Type: NS Type(Single Side Self-adhesive), ND Type(Double Side Self-adhesive)

For this article, we only talk about NS Type and ND Type.

Please refer to S-CLF II Super Tensile Strength Pre-applied Waterproof Membrane (Code: CHINA RED) for more information about YC Type of S-CLF Membrane.

 

※   Material Features

1. Excellent Physical Properties

S-CLF reinforced bitumen membrane has excellent physical properties and high tensile properties, which is 2~3 times of that of the traditional non-tire self-adhesive coils.

2. High Thermal Stability

Excellent thermal stability, grayish white surface, can effectively reflect light.

3. Excellent Elongation & Dimensional Stability

S-CLF self adhesive bitumen membrane is composed of super cross laminated film imported from Valeron, with good dimensional stability, can effectively reduce the fold, warping and other conditions; with excellent elongation, can adapt to the deformation of the base.

4. Strong Bonding Strength

The bitumen membrane sheet can be bonded tightly to the substrate, if there is local failure on the membrane, water would be confined in a limited area without fluid-channeling, which makes it much easier to repair.

5. Simple Construction Method

Under the same physical performance conditions, the coil is lighter and thinner. Thus, more convenient and faster for the application.

6. Skin-type Waterproofing

For Pre-applied S-CLF Membrane, the upper surface is an anti-sticking layer, which can effectively prevent workers from sticking feet and has a certain puncture resistance effect. In the construction of the basement floor, it can be reverse bonded with the post-cast concrete to achieve the "skin type" waterproof effect, and the bond is firm, even still inseparable with the concrete after long-term immersion.

 

※   Scope of Application

S-CLF polymer bitumen membrane is applicable to waterproof and anti-seepage projects in basement, roof, and other parts of industrial and civil buildings.

 

※ Construction Methods

S-CLF Super Tensile Strength Self Adhesive Bituminous Waterproofing Membrane (NS & ND Type) 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 peel and stick roofing underlayment 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. Dry 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 self adhesive rolled roofing 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㎡asphalt waterproofing smoothly on the screed-coat, then check the 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 self adhesive roofing underlayment 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.
