Bondsure® S-CLF Self Adhesive Bituminous Waterproofing Membrane Super Tensile

※  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

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.

1. Wet Application

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. 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 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 ㎡ membrane 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 waterproofing bitumen membrane 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 S-CLF waterproof self adhesive membrane is under normal storage condition.
