2. WATER PROOFING
• Waterproofing is the process by which a substance is applied to a surface, be it
concrete, leather , clothing or sporting goods, that renders the surface impermeable
to water.
• It creates a barrier that makes it impossible for water to pass through the material.
• This property prevents flooding and dampness in buildings.
• It helps reduce humidity inside the house and there by protects things inside our
house from damage caused due to humidity or water exposure.
WATER PROOFING COMPOUNDS
• These are the various materials that used for water proofing.
• These compounds are available in the form of the sheet, tape, liquid compounds ,
etc.
2

3. THE VARIOUS WATER PROOFING COMPOUND ARE:-
• NEOPRENE.
• BUTYL.
• E.P.D.M.
• P.V.C.
• POLYURETHANE.
NEOPRENE-
Neoprene (CR) , also called Polychloroprene or chloroprene
rubber, synthetic rubber.
Produced by the polymerization of chloroprene. A good
general purpose rubber, neoprene is valued for its high
tensile strength, resilience, oil and flame resistance, and
resistance to degradation by oxygen and ozone; however ,
its high cost limits its use to special properties application.

BUTYL:-
• Isobutylene was discovered by Michael Faraday in 1825.
• It was later developed into butyl rubber in 1937, by researchers William J. Sparks
and Robert M. Thomas, at Standard Oil of New Jersey's Linden, N.J., laboratory.
• Today, the majority of the global supply of butyl rubber is produced by just two
companies, ExxonMobil, the successor to Standard Oil, and Polymer Corporation,
a Canadian federal crown corporation established in 1942 to produce artificial
rubber to substitute for overseas supply cut off by World War II.

6. • It was renamed polysar in 1976 and the rubber Component became a subsidiary,
polysar rubber corp.
• The company was privatized in 1988 with its sale to NOVA corp which, in turn,
sold polysar rubber in 1990 To Bayer AG of Germany.
• In 2005 Bayer ag spun off chemical divisions, including most of the Sarnia site,
creating LANXESS AG, also of Germany.
PERMA WATER PROOFING BUTYL:-

7. • Perma waterproofing butyl tape sf-50 is used for joint sealing of the metallic and
non metallic roofing such as aluminum, zinc asbestos sheeting. Penna butyl tape
can be use for sealing all joints in timber framed houses.
• This tape is used for covering the insulated air conditioning ducts.
• It is used for sealing all the comer joints and the joints between the horizontal and
vertical rcc surfaces of the sunken slabs of to nets and bathroom after water
proofing. It is also used for covering of all cutouts and pipe joints in the walls.

Process :-
• Make sure that the surface is clean and dry .
• Unfold the membrane
• Allow membrane to relax for 30 minutes to remove wrinkles .
• Open bonding adhesive ( voc based , volatile organic compound or solvent based)
and stir until color is uniform .
• Apply adhesive to the exposed deck and to the back of the membrane .
• Allow adhesive to dry until it is tacky .
• Roll the adhesive coated membrane back onto the deck where adhesive has also
been applied .
• Work slowly and evenly to reduce wrinkles .
• Use a push broom to sweep over the membrane .
• Repeat this procedure until all the membrane is secure .

• Polyurethanes are found just about everywhere
in modern life, and chair you are sitting on ,
the bed you sleep in, the house you live in, the
car you drive – all these , plus innumerable

FAILURE OF WATERPROOFING :-
• Water proofing makes up b/w 1% and 2% of the total cost of the construction .
• But accounts for up to 80% of the complaints .
• The biggest cause of waterproofing failure is workmanship .
• Poor surface preparation .
• Adhesion Failure (due to moisture content) .
PRECAUTIONS
• Adhesives used are highly flammable . Hence catch fire .
• So , keep away from fire , sparks , source of fire .
• Turn off electronic gadgets , stoves , heaters , until all vapours dispersed .
• Do not smoke .
• Close container after use .
• Keep away from eyes and use chemical resistant gloves and glasses .
• Read safety instructions on the product .
