Bituminous membranes are a popular choice for waterproofing buildings, including roofs, basements, and bridges. Made from bitumen, a by-product of crude oil refining, these membranes are highly durable and flexible. Their exceptional waterproofing capabilities and energy efficiency make them an ideal choice for a range of construction projects.

1- Bituminous Membranes That Are Laid Down with the Assistance of a Torch

After being laid down, bituminous membranes give off the appearance of a minuscule layer of watertight material that is completely affixed to the surface they are protecting. It is a flexible system that is capable of retaining its capacity to be waterproof while preventing cracks from appearing in the process.

– Main Uses

  • Rooftops that are level and covered with ballast for further protection
  • Balconies and terraces under tiles
  • Soggy locations
  • Basements, retaining walls, and other below-ground structures and walls
  • Underground garages
  • Bridges
  • Slabs for the raft and foundations
  • Protects a wide range of substrates in a diverse array of applications

– Advantages

  • Method that has all of its ties entirely secured
  • Resistance to the most severe climatic conditions
  • Ease of maintenance and repair
  • Excellent mechanical characteristics
  • A very high degree of resistance to mechanical damage and punctures

2- Bituminous membranes that have their own inherent adhesiveness

During the application procedure, the release liner that is on top of bituminous membranes that attach to themselves is peeled off. This allows the membranes to adhere to themselves.

– Main Uses

  • surfaces made of wood
  • potential sources of ignition
  • areas with little space, terrain that is steep, or points of interest that are difficult to access
  • Below-ground constructions such as basements, retaining walls, and other buildings and structures

– Advantages

  • It is not necessary to have a torch.
  • An installation process that is not only more secure but also more expedient.
  • Excellent adhesion even when the temperature is low; this product does not need any additional equipment.

3- Additional Bitumen-Related Technologies and Their Related Applications

– Bitumen Liquid-Applied Membrane

When it comes to generating smooth, entirely adherent, and risk-free systems, bitumen liquid-applied membranes are the best option. Due to the fact that they do not catch fire, these polymer modified bitumen emulsions may be applied without the need of a torch or flame. It is possible to utilize either coatings based on water or coatings based on solvents with them.

– Bituminous Tapes That Have the Capability to Adhere to Themselves

Sealing tapes made of polymer-modified bituminous material, with a self-adhesive adhesive; the top side of the tape is laminated with aluminum foil; the tape does not contain reinforcement.

– Hot Melt Bitumen

A polymer-modified type of bitumen (For production, bitumen 60/70 is used.) That is either elastomeric or plastomeric and is packed in a solid block is what’s referred to as “bitumen hot melt,” and this state goes by the name “bitumen hot melt.” In order to apply the block, it must first be heated, and then it must be put onto the substrate. This causes the production of a layer of waterproofing that is permanently bonded. In order to apply the block, the first step is to heat the block.
