for the industry professional on its 

campus. 

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on conventional and outdated 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 -

For horizontal application, the new concrete 

layer must be smooth and level and to be left 

to mature for at least 72 hours. Before laying 

the waterproofing membrane, the surface 

must be cleaned of any waste. 

All surface imperfections, protrusions, 

structurally unsound and loose concrete 

must be removed and repaired with polymer 

modified mortar using Dr. Fixit Pidicrete URP. 

Where the separate concrete layers are poured 

at different levels, the gaps must be filled and 

smoothed, in order to obtain a comparatively 

smooth surface. When cleaning the substrate, 

any pollutants, such as chemicals, curing 

agents etc., which may affect the membrane 

adhesion, must be removed. 

Installation of Dr. Fixit Flexshield 

membrane 

Whenever Dr. Fixit Flexshield membrane is 

being installed, it is highly recommended that 

the membrane shall be laid at the position 

and allowed to relax for at least 45 minutes. 

This will help releasing the tensions in the 

membrane. 

Always use geotextile 250 gsm for protection 

of the waterproofing membrane, loose laid on 

the concrete substrate. 

On the horizontal sections the Dr. Fixit 

Flexshield membrane is loose laid between 

two layers of geotextile 120 gsm. The adjoining 

membrane sheets are seemed using a splice 

tape, as the overlapping must be at least

150 mm wide. A 50 mm protective cementsand 

screed is laid on the installed horizontal 

sections of waterproofing system. 

Its purpose is to protect the waterproofing 

system from damages, during the installation 

of the supporting structure (reinforcing, 

concrete casting, vibrations etc.) 

In the vertical sections, the membrane may 

be fully adhered or loose laid using mechanical 

fastening at the upper end. The walls must 

be dry and smooth, without any lumps, sharp 

edges and protruding reinforcement. 

Aluminum flashings should be used for the 

mechanical fastening, sealed with Dr. Fixit 

Silicon Sealant at the upper end. In case 

of full bonding the membrane to vertical 

surfaces, these must be clean and dry. The 

bonding adhesive is applied both to the 

membrane and to the substrate in uniform and 

smooth films; so that a continuous coverage 

of both surfaces can be obtained (membrane 

and substrate). The adhesive is left to cure, and 

then the membrane with the applied adhesive 

is rolled onto the adhesive covered substrate, 

avoiding the formation of folds and creases. 

The adjoining membrane sheets must overlap 

by approximately 150 mm. 

The underground waterproofing system is 

finished at 500 mm above the level of the high 

soil waters. 

The protective layer of geotextile 500 gsm 

is spot-adhered to the vertical Dr. Fixit

steel screws for fixing to avoid rusting. After 

drilling holes and before fixing the screws fix 

Dr. Fixit Bathseal Tape on bottom as well 

as top side of the batten. This will ensure a 

perfect seal around the screwed area. The 

battens must have enough number of grooves 

depending upon the length of the roof, for 

efficient drainage of water in case there is 

breakage of tiles.

Methodology 









Light fitting casings, pipes, insert, etc., provided 

in the concrete raft floor and walls are to 

be grouted with a non-shrink grout, Dr. Fixit 

Bathseal Grout. The inserts shall be wrapped 

around with Dr. Fixit Bathseal Tape to ensure 

a water-tight fitting. 

Priming 



Application 

Spray apply Dr. Fixit Extensa to achieve 

minimum thickness of 2.0 mm 

Dr. Fixit Extensa is applied through designated 

equipment only. It cannot be sprayed through 

any other type of commonly available sprayers. 

Extend the Dr. Fixit Extensa coating up to 

the top and covering the overflow concrete 

channels all around the periphery of the pool. 

As per the plans drawn up by the structural 

engineer, lay the steel cage accordingly. 

System Life 

Expectancy 

of 10 years 

Reinforcing steel must be installed after the 

plumbing is complete. The steel is installed 

in a grid pattern following the requirements 

of the engineering calculations. Steel bar size 

can range from 3/8” diameter to 3/4” diameter 

depending on the requirements. 

Concrete spacers ensure the steel is not 

against the wall or the floor of the pool. 

This system allows shotcrete to be evenly 

distributed under and above the steel. 

a rule of thumb to remember when designing 

swimming pools is to minimize the number of 

separation joints between concrete sections 

in the pool! 

Finish the shotcrete area with wooden float. 

After curing and drying make angle fillets if 

necessary, all around the periphery of the pool 

wall with polymer modified mortar prepared 

with Dr. Fixit Pidicrete URP. 

Now the shell of the swimming pool is ready to 

receive further waterproofing system. 

Apply 1st coat of Dr. Fixit Fastflex maintaining 

the saturated surface dry condition. 

While the coat is still wet embed a glass fibre 

mesh of 2.5 mm x 2.5 mm of 50 gsm over the 

angle fillets and allow it to soak completely. 

Immediately apply one additional coat to 

sandwich this glass fibre mesh between the 

Dr. Fixit Fastflex coatings.

After the 2nd coat is completely dry apply 3rd coat of Dr. Fixit Fastflex and sprinkle coarse 

sand while it is still wet. This will provide the 

key for subsequent tile adhesive materials. 

Dr. Fixit Fastflex should be liberally applied 

around the inserts, pipes and the around the 

light fitting casings, sandwiched with an open 

woven mesh as an extra precaution about 

these points. 

Now, start the application of tile adhesives 

from ROFF range depending upon whether 

they glass mosaics, or ceramics and fill the 

grooves / tile joints with epoxy based RTM 

coloured tile grouts.

Methodology 

Preliminary Preparation 

Assess the problem area & suitably mark the 

spots for drilling grouting holes. If the intensity 

of running water is high & cannot be controlled, 

then divert the flow of water using a PVC pipe 

at the spot of leak. 

For heavy dripping, mark the spots in a grid 

pattern 150 mm centre-centre or in case of 

spot dripping drill at the point of leakage at an 

angle of 45o to the plane of grouting. 

Drill diameter for a hole should be 

corresponding to the packers in use (generally 

16 mm - 20 mm) & depth of the hole drilled 

to be 100 mm deep or generally half the 

thickness of the substrate. 

Fix alloy packers (non-return type) of 

dimension 14 mm x 80 mm with a suitable 

putty. Allow the putty to cure for 24 hrs prior 

to commencing the injection grouting process. 

Application 

Mix base & hardener in the specified 

proportions: 

Dr. Fixit PU Foam Injection - 10 parts of 

base : 1 part of hardener 

The mixing to be carried out in a completely 

dry container using a stirrer. 

After rinsing the pump using a PU Cleaner, fill 

the PU mixture into the pumping container & 

initiate pumping on a low pressure & gradually 

build up the pumping pressure suitably 

Stop pumping if back pressure is sensed or if 

the grout has oozed out of the adjoining hole. 

PU foam injection oozes out of the grouting 

hole & hardens primarily in 10-15 minutes. 

Complete curing of the PU foam will happen 

over a period of 24 hrs. 

Mix base & hardener in the specified 

proportions: 

Dr. Fixit PU Plain Injection - (2 parts of base: 1 

part of hardener) 

Dr. Fixit PU Plain Injection, resin injection 

to be pumped once the PU foam has set in a 

similar manner as that of foam. 

This will act as a secondary injection thus 

completely sealing the leaking cavity. 

Cut off the extended portion of the packer & 

seal the surface with suitable putty. 

Choice of PU injection grout, Foam/Plain 

depends on the condition of the substrate & 

severity of leakage 

Injection grouting for dampness using 

Pagel ZS 10 

Drill grouting holes at an angle of 45° on 

the wall adjacent to the area of leakage at a 

spacing of 500 mm centre to centre or less in 

a grid pattern. 

Fix PVC or MS nozzles (packers) in the grouting 

holes using Dr. Fixit Instant Leak Plug or 

epoxy putty. Allow the nozzle to set for 24 hrs. 

Add water at a ratio of 0.34-0.45 to prepacked 

cementitious grout Pagel ZS 10 mix to 

a uniform consistency using a mixing paddle. 

Using a grouting pump, inject Pagel ZS 10 

through the nozzle at required pressure. 

Grouting should commence from the lowest 

possible level & proceed upwards along the 

grid with the pumping pressure increased 

gradually. 

Continue pumping until the grout flows out 

from adjacent nozzle. Detach the pump & 

nozzle and seal the grouting hole with Dr. Fixit 

Instant Leak Plug.
