Byproducts/ Water proofing Materials
At our own refinery we manufacture bitumen based products which can be used in water proofing. The products include
- Bitubond (a cold applied adhesive for sticking bitufelt)
- Bituplast (a cold applied waterproofing compound)
- Bituminous Black (anti-corrosive, multipurpose black bituminous coating)
- Bitukote (cold applied emulsion for waterproofing and protection of insulation)
- Bituprimer (applied to any concrete, masonry, wooden or metal surface)
- Cable Compound (for cable box jointing)
Bitubond
Bitubond is manufactured from selected grades of bitumen with mineral oils. It is of semi-liquid, creamy consistency and supplied in ready to use containers.
Uses
- As cold applied bitumen binder in place of hot bitumen for sticking of bitufelt on metals, timber, tiles, asbestos, concrete and masonry surfaces
- Waterproofing the roofs of buses, tramcars and railway carriages
- As a mop coat over the existing waterproofing treatment, this will longivate the life of bitufelt.
Bituplast
A ‘Ready to use’ waterproofing compound formulated out of special grade of oxidized bitumen, carefully blended and compounded with fibrous and inert mineral fillers and volatile solvents to keep it plastic.
It remains plastic for a considerable length of time. Although the skin and eventually the interior hardens to some extent after application, a little further change takes place after a certain plastic limit is reached. It is therefore ideal under conditions where a degree of expansion, contraction and vibration is expected.
Bituplast can be applied even by unskilled labour after a little practise. It does not creep or flow when applied on a vertical or sloping surface. it adheres firmly to most surfaces. it is ideal for sealing of cracks, crevices on the roofing decks, walls, window skill and virtually all nooks and corners where accessibility of other standard methods is generally difficult.
Uses
- Stopping leaks and water proofing of porous masonry and cracked concrete
- It serves as a caulking agent for crevices for virtual joints between steel plates, folded sections, wooden joints, precast concrete, cladding, block, etc.
- Waterproofing and caulking in railway coaches
- Protection of buried structures or vessels, such as underground steel tanks, poles, etc.
- Protection of cooling towers and other installations where they require protection from water.
Bitumen Solution : IS-158
This is a multipurpose ready to use Bituminous Black Solution and is Lead free, Acid, Alkali and Heat resistant anti corrosive paint. It is manufactured to a specific formula for protecting the internal and external surfaces of Concrete, Masonary, Pipes and Storage tanks of Metal against corrosion. This can be easily and quickly applied by trowel. It is manufactured from bitumen solution grade obtained from our own refinery, blended with highly volatile solution to make it ready for use and test drying.
Uses
- Protecting the internal surface of fresh water tanks, pipes and fluid containers
- Protecting apparatus, equipment and machinery whcih are likely to be affected by acid fumes, alkali and water vapour
- Coating of steel and concrete water tanks both internally and externally
- Coating of wood work which is likely to be affected with water and humidity
- Coating of steel drums.
Bitukote
Bitukote is a dispersion of selected grades of bitumen in water with inert and fibrous fillers. In original form, it is dark brown in colour and on application, as it sets, turns black. Once it sets, it remains plastic and is able to accommodate movements of pipes or vessels whose thermal insulation it protects.
Bitukote when applied over thermal insulation, protects it and keeps the moisture away and maintains their thermal efficiency. It gives joint-less coating and the coating is impervious to moisture. It possesses plastic qualities and can withstand vibration, temperature fluctuations and accidental shocks.
Uses
- Waterproofing of buildings, particularly vertical surfaces where color(black) overrides the importance of protection against seepage during rainy season
- Protection of insulated surfaces, both for hot and cold pipes, reaction vessels, boilers, etc.
- Protection of buried steel pipes and structures as well as concrete foundations, leaky walls and roofs having numerous cracks for instant sealing in adverse weather conditions
- Anti-corrosive protection of steel, particularly suited for coaches, automobiles, subject to intensive vibration.
Bituprimer : IS-3384
Bitumen Primer is a bitumen based primer for the surface conditioning of concrete and timber substrates prior to the application of heat fused APP and SBS modified bitumen membranes such as UniTorch.
Features
- Versatile bituminous primer for porous and non-porous surfaces
- Used on concrete, metal and timber surfaces
- Economical and easy to apply
Application
Bitumen Primer may be applied with brush or roller. The applied film must be allowed to dry before being overlayed with any waterproofing treatment so as to avoid solvent entrapment.
Surface Preparation
As with all surface coatings, good preparation is of paramount importance to the success and longlife of the system.
- Ensure that the surface to be treated is dry and sound, free of loose, dusting or flaking particles and free from contaminants such as grease and fungus.
- Defects such as cracks, broken mortar joints, etc. are to be repaired prior to primer application.
Cable Compound
Cable jointing boxes and bus bars are to be filled with a suitable insulating material. Bitumen base filling compounds are ideal materials for cable jointing boxes, filling, impregnating and manufacture of insulating tapes.
The compound has highest degree of electrical insulation. When heated it can be poured and once it cools, it forms into a hard mass. The compound has low water vapours permeability, it is insoluble in water and subsoil chemicals. Hence it gives a high performance for electrical application as it offers resistance to weathering and to chemical reactions. The compound remains stable and it neither froths nor emits excessive fumes when heated to a temperature of 80°C above the softening point. Wherever the compound is used, the life is prolonged of metals like copper, brass, iron, lead or aluminium, zinc, galvanized steel and their alloys, because of the protective nature of compound.
Uses
- As insulator for filing cable jointing boxes of both electricity and telecommunication, even if they are operating at high temperatures
- As a protector from moisture, water and other environmental chemicals so as to avoid failure in the system and hazards to human life
- Asimpregnating material for manufacture of insulation tapes. 14
