GEOTRANS
ASPHALT PASSABLE MEMBRANE WITH GEO-TEXTILE COATING
Characteristics
Membrane manufactured with Megaflex Plastic Asphalt, with Geo-textile (Polyester) coating of continuous threads called wooden no wooden and with resins which increase the properties of adhesion to the asphalt layer.
It has central assembly of high density polyethylene and double asphalt layer. It is ideal for waterproofing that requires high mechanical strength and/or it is passable with and excellent aesthetic ending obtaining a durable and efficient waterproofing. In waterproofing exposed, once the membrane is applied, the surface has to be painted with Geotrans Paint or Geotrans Coating.

It is the solution for waterproofing surfaces where the membrane is exposed to the elements, inclusive when it is submitted to a high traffic. Also, in under floor waterproofing giving a high security if there are possible tears and puncturing caused by the work itself. Some waterproofing examples with this product are:
Concrete flat surfaces, easy reach terraces, building terraces, retaining walls, in flower beds, baths, swimming pools, gutters, balconies, cellars, watercourses, underground tunnels, under tiles or under carpets, etc.
Advantages:
- Specified for passable tile floors.
- Better strenght to dynamic puncturing.
- Better strength to abrasion
- Highest security in waterproofing systems
- Excellent aesthetic ending. Different colours coatings.
- Higher dura
- bility and strength to ageing and meteorological conditions.
- The efficiency of its coating is kept facing different circumstances of use:
- Solar radiation.
- Hail
- Frequent pedestrian traffic.
- Blows, punches, etc.
Warnings and Precautions
Rolls should be stored in interior places where they are not exposed to sun rays, rain or temperatures of less than 5ºC or above 35ºC. They should be taken only in the moment of using them.
The rolls will be stocked horizontally (in a pyramid way) up to a height of 5 rolls.
Ideally these products should be located on site at least two hours before their application, so as to ensure a balance with the ambient temperature and humidity. At room temperature about 5ºC special care will be taken when laying the roll, unrolled it slowly to avoid cracks, tears or other damages.
It is not advisable the applying of the membranes when the ambient temperature is less than 5ºC (41ºF).
The work must not be made with rainy weather and it will not be renewed until the surface is completely dry.
It is advisable to have carbon gas or chemical dust fire extinguishers to countateract possible fire focus which could be produced during the application step.
Packing
In rolls of 10,6 m2 (1,06 width per 10 m length). It has a Welding Strip of 6 cm width protected by an anti-adherent film, making easier the overlap between membranes.
The GEOTRANS membranes are introduced in the following range:
- GEOTRANS 4mm – Passable Membrane of 43 Kg.
- GEOTRANS 3mm – Passable Membrane of 33 Kg.
Application Method-(Standard IRAM 12627):
To ensure a correct waterproofing it is essential to follow the steps of application which are detailed below:
- SURFACE PREPARATION: The surface where the membrane will be applied must be dry, clean, flat, stable, even, smooth and must have the necessary ways to drain the water it will receive.
-
PRIMING: Before applying the membrane the surface will be primed so as to improve the crub with the substrate. Megaflex Asphalt Primer (solvent base), Megaflex Asphalt Emulsion (watery base) or Oxidised Asphalt in cakes of application in heat, according to the characteristic of the work could be used.
The priming product is to be applied in an uniform way over the entire surface, including all extensions such as chimneys, airing elements, drainages and flashings. Allow to dry and check also for the cleanliness before applying the membrane
- APPLICATION: The rolls will be applied continuously from the lowest side (drainage) to the highest side of the surface, applying the rolls in perpendicular direction to the slope of the surface. Start by applying the first roll in perpendicular direction, ‘the roll display’ will be made, checking its position on the area to be waterproofed, then it will be rolled again to start the bond.
-
BONDING: Heat the surface of the membrane to be welded (anti-adherent) with welding torch, melting completely the anti-adherent and superficially the asphalt. Bond to the substrate by pushing softly.
- OVERLAPS: The following membranes’ layers will be applied superimposed up the direction of the overlapped slope, with an overlap no less than 8cm (3,2’’) in longitudinal sense. Roll endings must be overlapped 15cm (6’’).
-
MAKING FLASHINGS: At last the making of flashings on the perimeters walls will be finished with double membrane around the wall and floor joints.
- ENDING: Once the applying of the rolls is over, it must be applied (in two coats) GEOTRANS PAINT all over the surface (approximate efficiency 0,5kg/m2).
This coating achieves a better waterproofing efficiency and a high strength to abrasion, it means the wear because of the traffic. Besides, it protects the geo-textile coating form the sun rays and gives a nice aesthetic ending.
