1. Waterproofing
Waterproofing describe as making an object/ building/
space water tight or water resistant.

2. Bitumen
• Produced from petroleum distillation residue(From
Crude oil).
• Hydro-Carbon.70-80 % carbon 10-20% hydrogen
5% of oxygen, Sulfur and Nitrogen etc.
• Black and brown in colour.
• Plastic qualities (expand in heat but never went to
original state)
• Viscous (Thick and elastic)
• Ages- It ages with time so the properties are (In
contact with atmosphere it oxidized.) and make it
brittle, rough and hard.
• Good adhesive in favorable conditions.
• UV rays fasten the process of decay and convert

4. Asphalt

bitumen.
• Produced for industrial use.
• Sheets of asphalt produced
for waterproofing and other
industrial purpose.
• Increase durability than
bitumen.
• Ignite when expose to spark
or open flame at high
temperature.
• Water repellent.

6. Polyurethane sheets
• Diisocyanates mix with many
chemicals to produced
Polyurethane Compouned.
• Founded by Dr. Proff. Otto
Bayer
• Insulating material
• Weather resistance

7. Marine Board
• Consciously carved material for
using in marine decks other
places where normal Ply board
can’t stand.
• Insulating material
