While bathrooms are waterproofed presently the conventional practices have several limitations such as : • The PVC pipe inserts do not adhere well with the brickbat coba / cement / concrete used for filling the
area and joints around the pipes
• The polymer waterproof coatings and brickbat coba have limited ability to withstand cracks • Insufficient attention to detail in the corners and joint areas of the bathroom

bathrooms with a life expectancy in excess of 15 years ! The Dr. Fixit Bathseal system ensures a completely watertight bathroom that meets international standards for wet area waterproofing by :

How Bathseal system creates a leak-free bathroom
Key sources of leakage in a bathroom
Conventional methods of treatment Bathseal System
Gaps around pipe inserts
The gaps around the pipe inserts through the masonry walls and concrete floor are filled with ordinary cement which has poor bonding with the pipe materials (PVC). Cement has natural tendency to shrink upon drying leading to development of cracks around the pipes and hence seepage of water.
A unique first of its kind double
sided adhesive, bituminous Dr. Fixit
Bathseal Tape is used to wrap around pipes. The gaps are then filled using
non-shrink, cementitious Dr. Fixit
Bathseal Grout. Gaps around
nahani traps
Conventionally, cement is filled in the gaps around the Nahani traps and pipe inserts in wall & floor. This develops cracks & water seepage over a period of time. Moreover cement has a tendency to shrink on drying.
Filling the gaps with self levelling,
non-shrink, cementitious Dr. Fixit
Bathseal Grout reduces the risk of cracking and seepage.
Waterproofing of sunken portion
Conventionally, brickbat coba is done with or without a coating of latex. The brickbat coba/latex coating is not very flexible & can crack over a period of time allowing water to seep through.
Sunken portion slab is treated with two coats of polymer modified, cementitious, elastomeric waterproof
coating, Dr. Fixit Bathseal WPC.
The coating is 1 mm thick, has high elongation and impermeable to ingress of water
Gaps around sanitary wares
Gaps around sanitary wares are usually filled with white cement, which shrinks & cracks over time. With usage, white cement also attracts stains and has a poor surface finish.
Use Dr. Fixit Bathseal Sealant - An Acrylic Sealant for sealing gaps between sanitary fittings and tiles like wash basin, commode and bath tub.
Wall Slab Junction
Seperation joints in the wall & slab junction can lead to water seepage.
Angle fillet is prepared with Dr. Fixit Pidicrete URP Latex. The wall & slab junction is reinforced with a woven glass fibre mesh between the first &
second coats of Dr. Fixit Bathseal WPC
coating.
Splash zone (Shower area)#
Usually no waterproofing treatment is done on the walls of the splash zone of the bathroom (shower area). Water can seep through the walls through the tile joints & lead to dampness on the walls adjoining the bathroom.
The walls of the splash zone is to be treated with two coats of polymer modified, cementitious, elastomeric
waterproof coating, Dr. Fixit Bathseal
WPC up to height of 1800 mm.
In addition to the above product range, the kit contains
• Open woven glass fibre mesh to sandwich between the first & second coat of Dr. Fixit Bathseal WPC.
• Hand-gloves for safe handling of chemicals
• Application instruction booklet to carry out the waterproofing job scientifically
