Dynamic Exteriors is a preferred choice as a highly credentialed and experienced roofer. Most common for use in residential flat applications are two-ply, modified bitumen membrane systems.
Dynamic Exteriors is a certified installer of IKO modified bitumen membrane systems which provides homeowners with a superior standard of installation quality. For commercial and industrial flat roof applications both modified bitumen, and Built up hot Tar and Gravel (BUR) Systems represent the most commonly applied water-proofing assemblies. TPO and EPDM (Single ply membrane systems) are alternative systems for application in the commercial arena.
One of the basic items during the design and construction of a facility is moisture protection, which must be done well in order to obtain a facility that will last for many years. With good protection from moisture, the building will be resistant to damage for many years.
The impact of water from the atmosphere can have negative consequences on the walls, floors and roof of the building itself through condensation. This negative effect of atmospheric water condensation often appears as wetting of the walls, slight damage to the inner decorative layer in the rooms, falling off of plaster, wetting of the walls, appearance of mold, appearance of protrusions and inflating, and even falling off of facades. With the roof leaking, water is inside the building and yellow stains can often be seen on the ceiling.
All these damages negatively affect the aesthetics of the space itself, that is, the building, making it old and dilapidated.
Bitumen is protection against moisture and protection against the effects of water from the atmosphere.
Bitumen is one of the older materials for protection against moisture and water penetration. Bitumen was used in ancient times when the Babylonians and Hindus used it to insulate the walls of the temple. Later, the ancient Romans also used bitumen to insulate pools and reservoirs. Today, bitumen is used for waterproofing in the form of sediment left over from oil refining or bitumen obtained by refining petroleum products.
Bitumen is a thick sticky black resin with high oil. Bitumen is one of the basic waterproofing of office buildings, commercial buildings, residential buildings. Bitumen is widely used for traffic infrastructure.
Bitumen can be obtained from nature in two ways:
- The first way is exploitation from earth deposits where it is found as bituminous sand.
- The second way is in bituminous lakes (bituminous lakes are quantitatively and geographically limited,
they are located in Trinidad and Tobago and represent a natural phenomenon.)
Bitumen is also obtained by industrial processing of crude oil, refining.
Bitumen is often said to be tar, and even asphalt, because it is an indispensable part of the asphalt base in combination with sand and gravel, bitumen serves as a binder.
What is modified bitumen roofing?
Modified bitumen is bitumen that contains some additives. Modified bitumen is used for the production of tapes intended for waterproofing various surfaces, protection from moisture, atmospheric water, groundwater. Most often, modified bitumen is used for waterproofing flat roofs. The characteristic of modified bitumen is that it melts at 120 degrees and does not crack when it is cold at -10 degrees.
The modified bitumen roof (MB) is intended for buildings with flat weeds or commercial buildings with a small slope. Modified bitumen roof is waterproof. This roof is most associated with Built-up-Roof (BUR)
Bitumen is widely used in the construction of roads, runways, bridges, waterproofing foundations, waterproofing walls and roofs, especially for waterproofing flat roofs, it is also used for the production of varnishes and paints, for watering batteries and cables, for protection against corrosion-induced industrial bitumen.
Bitumen as a waterproofing is a product that is produced as hot bitumen and cold bituminous coating.
Hot bitumen is in a solid state, in order to be used it needs to be heated to 356 degrees Fahrenheit (1800C) to turn it into a resin that can be coated on surfaces.
Hot bitumen is used as a means of waterproofing both for underground works (to ensure waterproofing and waterproofing of foundations, basement walls, floors) and for aboveground works (waterproofing of flat roofs, terraces)
Hot bitumen is packed in buckets of 20 to as much as 200 kg. As it is flammable, it needs to be transported and stored in places that are protected from sparks or open flames. Shelf life is unlimited if stored in the original packaging which is also used for heating.
Bitumen is heated to a temperature of 180 0C, it is necessary to stir during heating so that it does not burn. The temperature must not exceed 180 degrees to avoid burns. Therefore, leave the roof waterproofing to a professional DE team that has many years of experience in performing roof insulation.
Before you place the bitumen on your flat roof, it is necessary to prepare the roof itself, clean it, then apply the bitulite base on a clean and dry roof, and then spread the bitulite with smooth straighteners and spatulas.
We often get questions
How much bitumen goes per square meter?
The average consumption of bitumen per square meter is 2 kg for a 2 mm application.
Can two coats of bitumen be applied?
Yes, two bituminous spreads can be applied, but only when the first coat is completely dry.
Cold bitumen is used as a factory-prepared coating that differs in the type of polymer. The first is polyhembitol, a bituminous multilayer coating reinforced with polymer resin and cellulose fibers. This bituminous multilayer coating is applied in places where larger dilatations of the substrate can occur, serves to repair dilapidated waterproofing and can serve as a good support for waterproofing.
The second is polyazbitol, which is a bituminous paste that contains organic solvents suitable for roof waterproofing, in addition to marking and repairing water. This bituminous paste is used for anti-corrosion protection of metal surfaces, especially in places where water can penetrate around gutters and protrusions for ventilation on the roof.
How is cold bitumen laid?
Cold bitumen is placed on a substrate that must be well cleaned of dust and grease. The basis for laying cold bitumen is bitulite or bitulin, which serve as a primer. The advantage of cold bitumen is that after opening, the coating only needs to be stirred and is ready for use. Cold bitumen is a liquid state, unlike warm bitumen, which is a solid state and needs to be heated to become liquid.
How much cold bitumen is applied?
Cold bitumen is applied two to three times, but it takes at least 48 hours from the previous application of the next layer of bitumen. When applying cold bitumen, the glass mesh is pressed while the bitumen is wet. It takes about 48 hours for the bitumen to harden.
When working with cold bitumen from the inside, it is necessary to ensure ventilation of the room, ie the flow of fresh air. If you work with cold bitumen on cold days, it is necessary to ensure the storage of the same bitumen in a closed room the day before installation, because when it is cold, the bitumen hardens quickly.
Which bitumen is used on flat roofs?
On flat roofs, polymer modified bitumen is used, which is also used to make a bearing or wearing layer in all types of traffic.
What is the price of laying bitumen on a flat roof?
The cost of installing bitumen depends on whether it is necessary to vacuum the roof beforehand, whether there is gravel, whether there is dust on the roof, whether there are cracks that need to be filled before pouring the bitumen. The price also depends on the surface of the flat roof as well as the folds and protrusions that need to be covered. The price of bitumen on a flat roof also depends on the agreement on how many times the bitumen will
be applied, whether it is a final layer or serves as a waterproofing.
