Waterproofing is a process that is designed to prevent water from penetrating a structure. Typically
waterproofing is done in various layers and stages to create multiple barriers so that water cannot penetrate
the structure. A combination of such stages is referred to as creating a “Building Envelope”.
However, often not enough importance is given to this very crucial area while constructing new structures.
Over reliance on conventional and outdated systems, low awareness about modern waterproofing systems
and lack of trained expertise for application are some of the reasons for the same. Here’s where Dr. Fixit
can help you to get the best waterproofing solutions for your new constructions. Dr. Fixit is India’s leading
brand in Waterproofing with a wide variety of products and solutions to meet all your waterproofing needs
- from foundations to walls to roofs. With access to the latest global technologies through its international
subsidiaries and R&D centres,
Dr. Fixit constantly brings innovative waterproofing solutions. Dr. Fixit also offers full technical support with
large pool of trained applicators.
Call us now to benefit from our state-of-the-art waterproofing systems for your new constructions.
Roofs are exposed to severe weather conditions throughout the year. If
not waterproofed, it leads to damp patches on ceilings, resulting in water
seepage, thus impacting the durability of the structure.
Conventional method of waterproofing like Brickbat coba has its
limitations. It is an excellent system for slope, but not for waterproofing.
Brickbat coba is inelastic and hence cracks due to thermal stress. It
stores water and allows water seepage into interiors. Contrary to the
popular belief it has very low insulating properties and rather proves to
be dead weight on roofs.

SURFACE PREPARATION
Clean the surface thoroughly to get rid of all contaminants. Remove all
surface imperfections and repair with a polymer modified mortar using
Dr. Fixit Pidicrete URP.
APPLICATION
1. Prime the surface using Dr. Fixit Torchshield Primer.
2. Lay Dr. Fixit Torchshield AP 4160, an APP based polyester reinforced
membrane, by providing an overlap of at least 100 mm.
3. Place a geotextile fabric of 150 gsm over the membrane before
laying the concrete screed M20 grade with a minimum slope of 1:100.
4. For extensive roof gardens, prime the screed using Dr. Fixit
Torchshield Primer.
5. Torch-apply Dr. Fixit Torchshield AR (anti-root membrane) on the
screed.
6. Place a drainage board as specified over the concrete screed.
