1. Cost-Effective
Manufactured by patented production technology, can be bonded with
unsolidified cement, to completely eliminate water-channeling.
2. Unique Wet-application Technology
Can be applied on wet or uneven substrate surface. No need of
primer, not affected by the weather. Especially during rainy
season, the advantage is more prominent when compared with
hot-applied membrane.3. Reliable Bonding of Overlapping Edges
As the membrane is made of self adhesive bitumen, it's very easy to
do the treatment of overlapping areas.
4. Strong Bonding Strength
The high polymer self adhesive waterproof membrane 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. Safe & Environmental-friendly
During construction, there is no solvent or fuel involved. Avoiding
pollution, fire risks and saving resources as well.
※ Scope of Application
PET Tar Felt Sheet Roll Bitumen Waterproofing is applicable to waterproof and anti- seepage projects in
basement, roof and other parts of industrial and civil buildings.
PET Aluminum Foil Covered Self Adhesive Waterproof Sheet 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. 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.
