Bondsure® BAC Double Sided Self Adhesive Bituminous Root Resistant Waterproofing

※  Material Features

1. Root Resistant

It can effectively prevent plant roots from penetrating the coils for a long time, maintain the integrity of the waterproof layer, prevent root puncture, and do not affect the normal growth of plants.

2. Convenient And Reliable

3. High Tensile Strength

BAC Root Resistant Membrane has high tensile strength, large thickness of modified asphalt coating, and strong adaptability to shrinkage deformation and cracking of base.

4. Cold Sticking Construction Method

Cold stick construction, no adverse effect on the lower part of the ordinary waterproof layer.

5. Anti-high and Low Temperature

Excellent resistance to high and low temperature, suitable for both hot and cold areas.

6. Strong Weatherability

Good corrosion resistance, mildew resistance and weather resistance.

※  Scope of Application

※  Root Resistant Tests

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 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.
