Product performance

* Active and structural concrete together, bonded firmly, permanently effective.

* Active healing aperture below 2mm damage, super self-healing ability, showing excellent water tightness of nail rod.

* Actively lock leakage point, eliminate the root of water channeling, convenient maintenance.

* Active absorption and solution of structural stress, resistance to structural deformation and cracking ensure the permanent effectiveness of waterproof layer.

* Active self-protection, strong cross-laminated film and durable reactive self-adhesive sealant protect each other from damage.

Classification and specification

* According to the adhesive surface is divided into single-side bonding(S), double-side bonding(D)

* According to the physical properties are divided into type I and type II

* The nominal width of the coil is: 1000mm

* The nominal thickness of the coil is: 1.2mm, 1.5mm, 2.0mm

* The nominal area of the coil is：25㎡，20㎡， 15㎡.

The specifications are as follows：

Construction technology

* Base treatment: the base should be strong, dry, clean (no dust, no oil), protruding parts and cracks should be leveled with polymer cement mortar

* Brush base treatment agent: containers containing the treatment agent should be stirred after opening the barrel. Brush should be used to brush around the base node, corner and so on, and then brush or spray construction. Keep the surface clean after drying. If any pollution the surface becomes dirty, brush it again. After drying, adhesive the coiled material in time.

* Node treatment: for gutters, deformed joints, waterfall openings, outstretched roof pipes, roof entrance should be treated in accordance with “the provisions of the roof engineering technical code”(GB50345-2004), and the parts need with reinforced or additional layers should be arranged in accordance with the regulations.

* The coils laying:

1. Horizontal laying: first, a baseline should be played on the base level, and then be paved from low to high.. At the same time unfold the coil, uncover the isolation paper, lay it along the baseline, and the width of the coil lap is ≥ 50 mm (full adhesive), ≥ 60mm((empty laying, sticky). After paving, the roller should be compacted with rubber roll immediately.

  2. Vertical head: vertical surface is paved from low to high, unfold and uncover the isolation paper. The width of the lap edge is the same as before, and be compacted with the rubber roll after laying.

  3. Coil head: the head should be sealed with sealant and then pressed with metal strips. The fixed screw and top seam should be sealed.

* Construction inspection: check whether all the self- adhesive coils are tearing, damaged, bubbles, and curled edges. If there is any defect, it should be cut at the defect, remove the bubble and restore it, and expand the area on the top, stick it together and compress it tightly.

* Protection of waterproofing layer: protection should be made according to “the provisions of the roof engineering technical code”.

Executive Standard

<< Pre-laying/ wet laying waterproof membrane >>GB/T23457-2009P

 Matters need attention

* During construction, attention should be paid to protecting the lap edges of coil materials from being polluted and maintaining the cohesiveness.

* When the wet laying method is used, it is necessary to ensure that the air between the material and the mortar is completely eliminated, and the pressure roller is rolled to make the reaction full of adhesive and cement. After construction, it is strictly forbidden to tread on the waterproof layer and other physical damage. Protective layer need to be made after acceptance.

* When the dry laying method is used, the base is required to be dry and smooth, and the base treatment is carried out with a special base treatment agent.

* Base treatment agent and sealing paste for head collection are special materials for self adhesive coil.

 Application Range

* Basement and roof waterproofing for industrial and civil buildings.

* Planting greening and waterproofing of basement roof and roof.

* Subway, tunnel engineering, pool.

* Waterproofing works with corrosion and large deformed parts of structure.

* Works that require high moisture-proof and waterproofing, such as sugar storage, grain depot, electronics factory, pharmacy workshop or warehouse, etc.

Transport and storage

* The coil should be stored in a dry and ventilated environment, and protective measures should be taken to avoid sun and rain.

* During transportation, products of different types and specifications should be stacked in categories and can’t be mixed up; far from heat sources, no contact with acid, alkali, oil and organic solvents.

* During transport, it should be placed horizontal or vertical to prevent tilt, pressure and if necessary, cover with felt cloth.

* Storage temperature not exceeding 45℃, height of amplifier not exceeding 5 layers.

* Under normal storage and transportation conditions, the storage period is 12 months from the date of production. Once exceed the storage period, the products can also be used normally after passing the inspection.
