WATER PROOFING TREATMENT OF ROOF SLAB [A STEP BY STEP GUIDE]

Suryakanta | May 31, 2022

WATER PROOFING TREATMENT OF ROOF SLAB

In this method polymer modified cementitious slurry coatings are applied over the base concrete. This technique of waterproofing is latest development in the field of waterproofing.
Polymer imparts significant improvement in impermeability.
Polymer modified cementitious slurry has coefficient of expansion very similar to concrete thereby it does not get cracked due to thermal variation of concrete.
Polymer modified cementitious slurry coatings consist of a liquid blend and a dry blend. The liquid blend consists of the polymer, liquid additives, and clean water. Dry blend consists of locally available Portland cement and aggregates.
These blends are mixed in specified ratio generally 2:1 (cement: polymer) by weight and applied by brush on a prepared clean surface.
Generally, two coats are provided. However, manufacturer’s recommendations should be followed in this regard.

To impart more flexibility, it is desirable to use some reinforcement like fibre glass cloth sandwiched between two coats.

This coating should be covered by screed concrete to protect it against physical damage.
This system can be used over new as well as old roofs.
Following steps are involved in application of this system.

I) PREPARATION OF ROOF SURFACE:

The surface shall be cleaned to remove all dust, foreign matters, lose materials or any other deposits of contamination. Cracks and depression shall be filled up by fillers. Prepared surface shall be thoroughly pre wetted for one hour.

II) PREPARATION OF POLYMER MODIFIED CEMENTITIOUS SLURRY:

Dry blend and liquid blend shall be mix into the desired ratio as per recommendation of supplier. The mix shall be stirred thoroughly, until no bubbles remain in the mix. Any lump found in mix shall be removed.

III) APPLICATION OF FIRST COAT:

First coat of polymer modified cementitious slurry shall be applied by brush on wet cleaned surface.

IV) LAYING FIBRE GLASS CLOTH:

Subsequently, fibre glass cloth shall be laid over first coat of polymer modified cementitious slurry.

V) APPLICATION OF SECOND COAT:

Second coat of polymer modified cementitious slurry shall be laid over fibre glass cloth in a criss-cross direction to the previous coat.
The minimum thickness of the dry film of complete application should not be less than as recommended by manufacturer’s specification

VI) APPLICATION OF BRUSH TOPPING:

Polymer modified cementitious brush topping shall be applied over second coat of polymer modified coating.

VII) APPLICATION OF SCREED CONCRETE:

On brush topping, screed concrete, admixed with suitable integral water proofing compound 25 to 40mm thick to a min. slope of 1 in 100 (or as per drawing), with aggregate size down 10mm with maximum water cement ratio 0.45, shall be laid.
Above system may slightly differ from case to case depending upon the instruction of supplier of water proofing system.

VIII) AT JUNCTION OF PARAPET WALL AND ROOF

The fillet (angular or concave, not convex) of adequate size should be provided all along the junction of parapet wall with roof.
Water proofing system should be extended from roof to parapet wall for a minimum height of 150 mm with a chase.

This is what an Igloo looks like when you build a fire inside. The fire inside melts the inner layer of ice, and the cold outside refreezes it adding a layer of insulation that can keep the igloo at 15° C inside while it's -45°C outside.

ભગવાન શ્રીરામજીના
વિવાહ અને રાજ્યાભિષેક
બંને શુભ મુહુર્ત જોઈને જ
નકકી થયેલા, તો પણ ના તો
તેઓનુ વૈવાહિક જીવન, ના તો
રાજ્યાભિષેક સફળ થયા. અને જયારે મુનિ વશિષ્ઠ પાસે જવાબ માંગવામા આવ્યો તો તેમણે સાફ શબ્દોમાં કહી દિધુ ...


सुनहु भरत भावी प्रबल,
बिलखि कहेहूं मुनिनाथ,
लाभ-हानि जीवन-मरण,
यश-अपयश विधि हाथ

અર્થાત: જે વિધીએ નિર્ધારિત
કરેલુ છે તે થઇ ને જ રહેશે.

ના ભગવાન શ્રીરામજી
નુ જીવન બદલી શકાયું, ન
ભગવાન શ્રી કૃષ્ણજીનુ,
ન ભગવાન શિવ સતીના
મૃત્યુ ને ટાળી શકયા. જયારે
મહામૃત્યુંજય મંત્ર એના
વશમાં જ હતો, ન ગુરૂ
અર્જુનદેવ, ન ગુરૂ ટેઞ બહાદુર, ન ગુરૂ ગોવિંદસિંહ પોતાની સાથે થનાર વિધી ને ટાળી શકયા ...

જયારે સૌ સમર્થ હતા..

રામકૃષ્ણ પરમહંસ પોતાના
કેન્સર ને ટાળી શકયા ન તો
રાવણ પોતાના જીવનને
ને બદલી શકયો, સમસ્ત
શક્તિઓ હોવા છતા
વિધીના વિધાન ન ટાળી શકયા.

મનુષ્ય પોતાના જન્મ સાથેજ
જીવન, મરણ, યશ, અપયશ,
લાભ, હાનિ, સ્વાસ્થ્ય, બિમારી, દેહ, રંઞ, પરિવાર, સમાજ, દેશ અને બીજું ઘણું પહેલાજ નિર્ધારિત કરીને જન્મે છે.....

તેથી સરળ રહો સહજ રહો,
મન કર્મ અને વચનથી
સતકર્મમા લિન રહો.
મુહુર્ત ના તો જન્મ લેવાનુ છે
ન તો મરવાનું બસ વિધી
ના વિધાન મુજબ કર્મ જ
આપણા હાથમાં છે
શેષ બધુ અર્થહીન છે.
