Water Tank Waterproofing / Water Reservoirs:
Waterproofing is a State of Art. Waterproofing is not
difficult if you the Solution for the problem. The difficult
task of Waterproofing is to find the Source of the
Problem. Varieties of sources are present in the market
for the problem if the sources are known for illness, but
where doctors fails is to find the source and to fix it.

Water Tank/Reservoirs can be classified in to following ways:
Water
Tank/Reservoir
Open
Reservoir
Man Made:
Dams
Swimming
Pools
Nature Made:
Lakes
Ponds
Closed
Reservoir
Elevated Water
Tank
Over Head
Water Tank
Underground
Water Tank

As said earlier Waterproofing is state of Art. We have to choose the systems as per the requirements.
These waterproofing could be done in two Ways:
• During Construction Phase
• After construction
We don’t need to tell you; which is good way, RIGHT!!
Waterproofing during construction eliminates the scope of error and strengthens the structure. Providing the
great benefits and overview.
Never the less also, increases the life of Waterproofing and Structure both.
Post Construction Waterproofing is said as Rehabilitation in other word a REPAIR. Which is effective but not
as much as DC phase. Post Construction Waterproofing has its own limitation of Accessibility, Cost, Aesthetic and
Pragmatic; on the top it is a protection shield and not the original structure.
Here, we would discuss the Waterproofing of Over Head Waterproofing, Underground Waterproofing and
Elevated Tank Waterproofing. In earlier conversation we already talked about Waterproofing a Swimming Pools.
Depending on the condition of your Site you can choose the System:

1.During Construction Phase Waterproofing:
(A) Over Head Water Tank / Elevated Water Tank:
i.Surface Treatment before Casting:
- Finish the surface with smoothening tools to the mother slab with 1:4:1 Cement to Sand mortar to RajaCreteAP
mixed well.
- Post finish apply Raja BaseCoat (Acrylic Polymer based highly flexible waterproof coating) to DFT of 2mm to 4mm
for SLAB only.
ii.Casting:
-Add Raja CreteAD (An integreal Waterproofing Compound) which reduces the void and makes concrete
impermeable. (It is to be added to 1Litre to 100Kgs of Cement by weight)
Raja CreteAD makes any concrete impermeable if thickness of concrete is maintained at 6 inches with prescribed
dosage.
-If thickness is maintained at less than 6 inches; additional waterproofing is required.
iii.Treatment after Casting Slab & Retaining Walls:
- Applying Two Coats of Raja ChemCoat (Hybrid of PU and Acrylic polymer, highly flexible, Impervious and Elastic with
High Bonding strength even in constant contact of Potable Water) in a DFT of 2mm per coat.

(B) Underground Water Tank:
i.Surface Treatment before Casting:
- Surface has to be sound enough, in case bleeding surface use Raja Plug and seal off the bleeding surface and
in case of porus surface use Raja PorSeal to seal off the porus surface.
- In case of Deeper Tank, Use Shabad stoned Box Waterproofing to lower / break the negative water pressure.
Raja TripleAction in filling the slurry in the joints.
- Finish the surface with smoothening tools.
ii.Casting:
- Add Raja CreteAD (An integreal Waterproofing Compound) which reduces the void and makes concrete
impermeable. (It is to be added to 1Litre to 100Kgs of Cement by weight)
Raja CreteAD makes any concrete impermeable if thickness of concrete is maintained at 6 inches with
prescribed dosage.
- If thickness is maintained at less than 6 inches; additional waterproofing is required.
iii.Treatment after Casting Slab & Retaining Walls:
- Applying Two Coats of Raja CrMi (an intergral Crystalline based Waterproofing to resist the negative water
pressure up to 10 bars).

2.After Construction Waterproofing (Rehabilitation):
(A) Over Head Water Tank / Elevated Water Tank:
i.Cleaning The surface:
- Clean the surface thoroughly for loose portion, grece or any debris.
- Surface coating of the Primer is recommended to ensure better adhesion of the Waterproofing Coating to the
parent structure.
ii.Waterproofing:
- Applying Two Coats of Raja ChemCoat (Hybrid of PU and Acrylic polymer, highly flexible, Impervious and
Elastic with High Bonding strength even in constant contact of Potable Water) in a DFT of 2mm per coat.
(B) Underground Water Tank:
i.Cleaning The surface:
- Clean the surface thoroughly for loose portion, grece or any debris.
- Surface coating of the Primer is recommended to ensure better adhesion of the Waterproofing Coating to the
parent structure.

ii.Waterproofing:
- Depending on intensity, nature of leakage various methods could be chosen:
i.Injection Grouting
ii.Laying Shabad Stoned Box Waterproofing
iii.Crystalline Coating based Waterproofing.
iii.Soil Stabilization: Some time due to location of our underground water tank, the backfilled material or poured
concrete gets washed off, and could lead to water ingress, Use of Soil stabilized material could help in arresting the
leakage problem.
