APP MODIFIED BITUMEN PLASTOMERIC WATERPROOFING MEMBRANE REINFORCED WITH SPUNBOND NON WOVEN POLYESTER
What is ELASTOSEAL ?
Produced by the Modern Waterproofing Company, Betagum is a line of polymer-modified bitumen waterproofing membrane ofthe highest quality.
Betagum is modified by APP and APAO, thus guaranteeing superior performance under various conditions.
Elastoseal is reinforced with Spunbond Non-woven Polyester (P) which provideshigh mechanical properties.
Elastoseal is a general purpose membrane, can be applied virtually anywhere where torch applied modified bitumen membranes subject to light to moderate mechanical stresses are specified, and normal low temperature performance is required.
Elastoseal can be applied in:
• Single layer roofing system for normal use.
• Double layer roofing system combined with Elastoseal fiberglass reinforced.
• Waterproofing of toilets & wet area inside buildings.
• Slab on grade.
Elastoseal with Mineral Slated Finish is recommended for exposed roofing system (Unprotected) for Non-accessible roofs or roofs subject to low traffic conditions.
Elastoseal has been designed with special regard to providing clients with an excellent and versatile product line.
Advantages of Elastoseal include:
• Easy to apply (by torch).
• High mechanical properties.
• Absolute impermeability to water pressure.
• Flexibility at low temperature up to -2co
• Excellent high temperature performance.
• Excellent adhesion on any surface.
• High dimensional stability.
• Environmentally friendly.
The Modern Waterproofing Company is ISO 9001 certified. It applies a stringent quality control system utilizing its in-house laboratory.
Occasional samples are analyzed by independent laboratories to ensure continued adherence to the highest standards (ASTM, EN, etc.).
Each roll of Elastoseal is individually coded with a label containing all necessary information about the roll. This is intended to ensure traceability in accordance with ISO control standards.
Standard thickness available includes 3mm and 4mm. Some types could be available by weight 3kg/m2 and 4kg/m2.
Bottom surface finish is normally Polyethylene Film (PE).
Upper surface finish choices include:
- Polyethylene Film (PE)
- Fine Sand (S)
- Mineral Slated Grey (GY)
- Mineral Slated Green (GRN)
- Mineral slated White (WT)
- Mineral slated Red (RD)
Slated rolls are available in 4kg, 4.5kg and 5kg per square meter.
The nominal length of each roll is 10 meters and the nominal width is one meter.
Special specification can be designed based on client’s needs.
- Above results are based on 4mm membrane
- Tolerance within 20% of the above results for mechanical characteristics complies with the tolerance specification of (ASTM , EN)
- Due to constant product improvements, MODERN company reserves the right to change above values without advance notice
- Elastoseal membranes should be stored vertically in well covered and ventilated place not subject to direct sunlight
• Elastoseal membranes are installed by propane torch welding method, loose laid or fully bonded to the substrate depending on system requirements.
• While unloading from truck the rolls shall by no means allowed to fall or be thrown down from the truck.
• To avoid applying the membrane to corners with 90 ° angle, sand cement cant strip 5×5 cm should be executed at horizontal – vertical intersections.
• Surface to be waterproofed should be clean, dry, free from dust and smooth, in case of irregular surface a sand cement screed is recommended.
• Before laying Elastoseal membranes, surface should be primed with cold applied bituminous primer (NIROL – S) or (NIROL – W).
• Membrane is unrolled and placed in aligned position.
• Each roll should overlap the next by 10cm side laps and 15cm staggered end laps.
• Then, membrane should be re-rolled about half of its length without changing its orientation.
• Using a propane gas torch the membrane is un-rolled again slowly while applying the flame to the entire exposed lower face (For fully bonded system) – until the plastic cover film burns off and the bituminous mass starts melting, thus creating a heat weld between the membrane and the substrate.
• Then, torching of the seams takes place by heating the contact line at side and end laps by torch from above, pressing the upper membrane on to the lower one using a trowel, the torch has to be carefully used avoiding to keep the flame on the same point for too long.
• For sloping roofs start laying the membrane from the lower edge with longitudinal direction of rolls perpendicular to slope direction, side lap of next roll to be placed above the first one, etc…
