What is water proofing?
Water proofing is processes by which any structure of construction can be make water resistance. By cause of which the structure durable for long period and it is much more long life. Today’s life we can able to see that 8 out of 10 buildings are affected by water proofing causes. In case of renovation we are able to see that most of cases, damp in the wall, leakage from the roof or even the paint is uprooted from the wall etc.
The main reason is that waterproofing is not done in proper way or the materials is used is not the upgraded quality. Now the main question arises “Why we should be so careful about waterproofing”?
In old time when building is constructed there is no conciseness about water proofing. The material quality was so high and the structure was not so big is stated of today’s construction that water proofing may concern in secondarily or we can say lack of concern about waterproofing in that period.

Though in old cold construction some traditional water proofing done like roof IPS waterproofing, brick bat coba waterproofing etc. But this process is not long lasting and as time goes crack develops in it. In sated of that the labors are not so technically sound to execute this process so carefully. Thus create much more damage in long run and huge cost involved to uplift the portion and it is also create damage the existing construction part of the building also.
In care case damp proofing of external wall we think exterior color is the only option. But we don’t know that paint coating is 30-50 microns thick, which does not protect the wall from strong wind blow and also from the rains. For that the cracks developed in the external paint quoting and ultimately are damages badly. After wards damp seepages and damp patches can be found in many places in the construction.
Now a days there are different types new water proofing products has been introduce in the market which are elastic, lick free and much more thicker than the traditional products. This can make construction near about 100% water proof in long time.
In this regards
Dr. Fixit Roofseal Top Coat is single component, insulating elastomeric waterproof coating for roofs that offer a seal against water and heat. Dr. Fixit Roofseal Top Coat is based on PU - Acrylic hybrid emulsion technology reinforced with nano fibres. It combines the benefits of waterproofing as well as heat reduction in a single product.
Standard Compliance / Specification
Meet the ASTM D6083 - Type II standard specification
Areas of Application Over existing building Flat/ Slope roof surface like;
Brick-Bat Coba finish surface
Cement mortar screed
China mosaic tile roofs.
Method of Application
SURFACE PREPARATION
Surface preparation is generally limited to cleaning by broom brush or compressed air. All surfaces to be applied must be free from dust, loose material, oil, or any other material which may impair adhesion of the material. All surface cracks up to 5 mm wide should be filled up with the same material and pre-striped prior to application of the material. All joints of vertical up stand should have 50 x 50 mm angle fillets prepared with sand -cement mortar; mixed with Dr. Fixit Pidicrete URP.
PRIMING
Primer is required only for high absorbent surface such as light weight concrete. Primer recommended to be used is Dr. Fixit Torchshield Primer, when the surface is completely dry.
APPLICATION
· Apply a coat of Dr. Fixit Roofseal over an angle fillet as a reinforcing strip all around the parapet wall and allow drying. Apply on all vertical up stand at an average girth of 200 mm. Apply 2 coats Dr. Fixit Roofseal at 0.75 ltrs / m2/ coat, at an interval of 12 hrs between the coats and allow drying completely.
Water ponding test:
· After full drying of second coat for at least 72 hrs, a water ponding test can be performed by filling water on the terrace by carefully blocking all the down take drain outlets without damaging the coating. The test shall be carried out for 48 hrs by filling water up to 50 mm level. Observe for leakages if any and then remove the water and allow the coating to dry completely for about 24 hrs before proceeding further.
· Spread 100 gr m/m2 geo textile over, before a concrete screed is laid. Protect the coating with a concrete screed in M 20 grade. The protective screed should be of minimum 50 mm thickness maintaining an average slope of 1:100 towards the drain outlets for effective and efficient draining of water. After the application of screed, provide control joints along the length and breadth of entire screed area. The joint can be provided by using a saw cutting machine attached with a 3 mm blade. The joints will be 12 mm wide and 12 mm deep. 28-30 days later, these joints can be filled with a suitable elastomeric sealant.

Which are the places
essential for water proofing treatment?
These are
1. Foundation
2. Roof/ Terrace
3. Exterior Wall
4. Kitchen
5. Water tank
6. Swimming Pool
7. Balcony Area
What
are the effect we have to face if we not to go for waterproofing treatment of
the structure?
Mainly we face two types of problems.
1. Structural Stability related problem.
2. Health regarding Problem.
In case of structural stability related issues already discussed those cases of seepage from floor and create damp on wall, Create damp by internal waterline leakage in the toile of surroundings, or water seepage in concrete and create the reinforcement steel bear and open and continuous water contact water leakage inside the house and may create dangerous structural problem like collapse of structure.
Incase case of health related problem, it affect the mental and physical health of the habitant of the damp effected building. I create fungus and various types of bacteria which causes the allergies and respiratory related daises. This may case of life threatening daises. WHO (World health organization) is also concern about this. They declared that damp construction can create more than 50 types of daises.
So water proofing is very essential in today’s life.
