UNI ELAST (SBS)

UNIELAST SBS

DESCRIPTION

UNIELAST is the Ultimate Waterproofing Membrane. The multilayered design consist of non woven polyester core, impregnated and coated on both sides with SBS (Styrene-Butadiene-Styrene ) polymer modified bitumen and finally finished with fusible polyethylene film on both surfaces.SBS modified bituminous waterproofing membrane are product from a blend of special grade thermoplastic polymers and bitumen. This combination gives the proven waterproofing qualities of bitumen plasticity, excellent resistance to heat, ageing   and weathering and ease of application by torch welding. The polyester core gives the membrane high tensile strength, elongation and superior lap joint strength.

Features:

Ø  Total Impermeability for complete waterproofing.

Ø  Good bond ability and seam integrity.

Ø  Stability at high ambient temperature.

Ø  Good performance at broad temperature range.

Ø  Good flexibility.

Ø  Compatible with all roofing and building component.

UNIELAST it could be widely used in all kinds of waterproof engineering project in all fields,

Especially for the following types of engineering projects:

Ø  All kinds of building roof engineering projects, treading, non-treading, planting building surfaces.

Ø  All kinds of underground waterproof of damp roof engineering projects.

Ø  Water spraying pools, swimming pools, penstocks, water pools and similar works.

UNIELAST is available with two finishes

1-with polyethylene film both side (UNIELAST-S)

2- with polyethylene film one side and granular for the other side (UNIELAST-G).

UNIELAST is available (4mm, 3mm).

Surface Preparation:

Ø  Clean the surface smooth and free of moisture and debris or any kind of substance that would prevent the membrane from adhering properly.

Ø  The roof must have a minimum slope of 1 %( 10mm per meter) evenly and continuously towards the drains.

Ø  Surface must be primed with UIB Primer D41 or any other primers under ASTM 41.

Membrane Installation:

Ø  Unroll the membrane. Making sure that the edge (side lap joint) is aligned with the low point of the roof. Re-roll one end to the centre of the roll and apply; then proceed with the opposite half. Proceed up the slope with further rolls.

Ø  The end of the propane torch head should be positioned between 150mm and 300mm from surfaces, depending on the weather conditions. Maximum heat is obtained at the blue end of the flame. The welding procedure will be more if the torch and thus the flame are moved continuously in a rectangular pattern from the roll to the substrate. The movement should be slowed over the joint of the base sheet in order to apply enough heat to soften the bitumen   and to fill possible voids.

Ø  For best results, make sure that there is always a small amount of molten bitumen in front of the roll being heat welded. When in doubt, re-roll and strings of bitumen should appear between the roll and the substrate

Packing:

UNIELAST 23 Roll per pallet.

Storage and Handling:

Ø  Vertically stored the rolls in pallets.

Ø  Store under shaded warehouse.

Ø  Rolls in pallet should not be stored over the other.
