2. ď‚š 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.
ď‚š It creates a barrier that makes it impossible for water to
pass through the material.
ď‚š This property prevents flooding and dampness in
buildings.
ď‚š It helps reduce humidity inside the house and thereby
protects things inside our house from damage caused
due to humidity or water exposure
3. WATER PROOFING COMPOUNDS
• These are the various materials that used for water
proofing .
• These compounds are available in the form of sheet ,
tape , liquid compounds , etc.

DISADVANTAGES OF NEOPRENE
8. BUTYL
ď‚š Isobutylene was discovered by Michael Faraday in 1825.
ď‚š 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.
ď‚š 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.
ď‚š It was renamed Polysar in 1976 and the rubber
component became a subsidiary, Polysar Rubber Corp.
ď‚š 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.
ď‚š In 2005 Bayer AG spun off chemical divisions, including
most of the Sarnia site, creating LANXESS AG, also of
Germany.
9. PERMA WATERPROOFING BUTYL
ď‚š Perma Butyl tape SF 50 is a single sided butyl rubber adhesive tape
which is used for waterproofing all joints in construction industry,
during construction and post construction.
Primary Uses
ď‚š Perma Waterproofing Butyl Tape Sf-50 Is Used For Covering All
Cracks, Construction Joints, Bends And Corner And Joints Of Non
Homogeneous Materials Before Applicatioin Of Waterproofing
Membranes Such As Penna Guard Or Penna Eazee Coat.
ď‚š Perma waterproofing butyle tape sf-50 is used for joint sealing of
the metallic and non matellic roofing such as aluminum, zinc
asbestos sheeting. Penna butyl tape can be use for sealing all joints
in timber framed houses.
ď‚š This tape is used for covering the insulated air conditioning ducts.
ď‚š 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.

weatherproof water proofing membrane .
It has an exceptional elasticity and will not split or crack
under normal building movement .
E.P.D.M. exhibits satisfactory protection from heat ,
water , alkalis , acids , oils , weather protection ,
electrical protection , etc.
ETHYLE PROPYLENE DIENE MONOMER
13. ITEMS REQUIRED :-
E.P.D.M. membrane
Bonding adhesive
Roller
Knife or scissor
Push broom
Gloves and protections
14. 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 colour 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 .
16. Quick and easy to install .
Extremely flexible .
Excellent water resistance .
Contain no dangerous
substance .
Superior elongation .
Highly resistance to tearing
and impact .
Versatile , last for 40 years
and more .
Works at low temperature of
-50â—¦C and maximum of 150â—¦C
Low maintenance
E.P.D.M. comes mainly in a black
roll , which easily absorbs heat and
can lead to superheating of the
structure below .
It comes in light colour also , to
help reflect heat in summer climate
, but this adds about 30% more to
the cost of the material per square
foot .
If a workman wearing the wrong
type of boot could tear a hole in the
roof covering membrane i.e.
E.P.D.M.
DISADVANTAGES
18. PVC (PolyVinyl Chloride)
• PVC waterproofing membrane is a
modern roofing material, which is
made of high quality flexible
(plasticized) polyvinylchloride.
• Manufacturers of PVC membranes
offer diverse width and length of
the material.
• The width of the material ranges
from 3 to 7 ft.
• The rolls can be between 60 and
75 ft in length. The thickness of
the PVC membrane is 1.2 mm.
19. Features of PVC membrane
• PVC membrane is used mainly for waterproofing of buildings and
roofs.
• Since this material is quite easy to install, strong enough (is
of great tensile strength), has long service life,
• Due to its structure, the PVC
membrane is very strong and
simultaneously flexible material
which is resistant to precipitation,
ultra-violet radiation, capable to
withstand heavy surface and tensile
loads

26. POLYURETHANE
• We use polyurethane in one form or another every
day at home in our office and cars, for sport and
leisure activities and on holiday.
• Polyurethane are versatile, modern and safe.
• They are used in a wide variety of applications to
create all manner of consumer and industrial
products.
• Polyurethane is a plastic material.
History
• Otto Bayer and his coworkers at ig farben in leverkusen ,
germany, first made Polyurethane in 1937.
• The new polymers had some advantages over existing plastic .
• Early work focused on the production of fibers and flexible foams.
• Polyisocyanates became commercially available in 1952,and
production of flexible polyurethane foam began in 1954 using
toluene diisocyanate (TDI) and polyester polyols.
27. Uses of polyurethanes
• 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 other items you use every day
probably contain polyurethanes.
• It shows how versatile they are and also how they help
to protect the environment by conserving energy.
Common polyurethane applications
• Building insulation
• Refrigerators and freezers
• Furniture and bedding
• Footwear
• Automotive
• Coatings and adhesives
• Other applications
28. FAILURE OF WATERPROOFING
• Water proofing makes up b/w 1% and 2% of the total
cost of the construction .
• But accounts for upto 80% of the complaints .
• The biggest cause of waterproofing failure is
workmanship .
• Poor surface preparation .
• Adhesion Failure (due to moisture content) .
29. 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
vapors 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 .
