Types of Water proofing: 

Types of Water proofing Tar felt water proofing Bitumen Membrane Brick bat Coba Waterproof (wp) coating Cementitious water proofing Crystalline water proofing Integral Waterproofing Compounds Acrylic Based polymer coatings Protective and Decorative Coatings Injection grouts

Tar felt water proofing: 

Tar felt water proofing Very old system Not a permanent solution Cracks and fails over years Difficult to apply Not compatible with cement sand over layment Expansion and contarction of tar leads to cracking

Bitumen membrane : 

Bitumen membrane Comes in roll form Need flame to install Installation is very tedious and slow Cutting and welding has to be precise work Resists negative hydrostatic pressure Suitable for Concrete surface

Brickbat Coba: 

Brickbat Coba Conventional system Done by unskilled labor No data on performance Fails in 2-3years Costly :increases the load on structure Requires marble mosaic on it

Waterproofing Coating: 

Waterproofing Coating Is the simple bursh coating as per specification in tenders Results not known Applied in covered areas Used in toilets and bathroom Purpose no dampness to be seen on underneath of the slab/floor Not a full proof system

Cementitious water proofing: 

Cementitious water proofing Mostly polymer modified Thickness ranges from 1-2mm It is basically a surface barrier and not actually a true water proof membrane It has no elasticity and tends to crack over a period of time Does not seal shrinkage cracks It will crack as concrete develops shrinkage cracks Not suitable for heavy traffic areas Not suitable for exposure to chemicals Suitable for concrete and masonry surfaces only

Crystalline water proofing: 

Crystalline water proofing Consists of cement, silica sand and chemicals When mixed with water it causes a chemical reaction which results in crystalline formation in pores of concrete Closes all pores thereby reducing bonding for further mortar or adhesive laying Can be applied to concrete only Cannot be applied to smooth mortar surface Requires open pore surface for reaction Highly suitable for negative hydrostatic pressure and for applications such as Reservoirs, Manholes, Basements etc Not suitable for applications such as swimming pool or water bodies where tiling is to be done


Contd Due to chemical reaction between free lime and iron oxide in concrete it may cause efflorescence Not suitable for exposure to chemicals Will crack if the concrete cracks Requires curing for a min of 3 days Rich mixes have very less pores

Integral waterproofing : 

Integral waterproofing Used extensively in last decade It is additive to the concrete are either, pore fillers or water repellants Concrete slabs develop minute cracks due expansion and contraction hence they fail Only useful in case of damp condition

Arcylic based polymer coating: 

Arcylic based polymer coating Advance system used in coating Unbreathable Cracks develop in the system Not for old concrete Data on ablilty to take pressure not known not for ponded water Costly

Decorative and protective Coatings : 

Decorative and protective Coatings They are water repellants used on cladding Not a waterproofing material Not to used on flat surfaces

Injection Grouts : 

Injection Grouts Cheap method Results are not known No guarantee Can spoil the building due to ingress Time consuming

Kerakoll water proofing: 

Kerakoll water proofing Tailor made solution for client Part of a complete Kerakoll system Resists positive and negative pressure Resistance to anaerobic and acid aggression Thin, load bearing and high rated adhesion on the substrates Job proven for over 38 years Liquid, cold applied self curing membrane Requires no water curing Contains no solvents and flammables


Contd Suitable for Drinking water containment Suitable for application on various substrates such as Concrete, masonry and absorbent and non absorbent Tile/Stone can be directly fixed on the membrane Tiling can be carried out in 4-6 hours at 30deg c Flexible and hence does not crack Suitable for continuous water immersion Good chemical resistance Suitable for Industrial applications Easy to apply and clean, saves on labour
