Water tank waterproofing.

 

Before we jump into the topic of water tank waterproofing one must know the different types of water tanks.

There are major two types of water tanks:

  1. Under ground water tanks.
  2. Over-head water tanks.

 

Under ground water tanks:

This are built into the earth’s surface. As per capacity of storage the surface of the earth is dugged and then is coated with slurry of cement and concrete paste. Old traditional storage wells are excellent examples of underground water tanks.

In some cases plastic, fibre, etc based readymade storage containers are installed into the earth’s dugged area.

In most cases underground water tanks are concrete based.

Over-head water tanks:

This are built above the earth’s surface. They are also mostly found on terrace, balcony, etc. There are some huge elevated water tanks which store water in huge capacities.

Concrete and readymade plastic tanks are found in over-head tanks.

 

As per the type of tank the waterproofing methods also varies. We have enlisted down some major water tank waterproofing methods.

Some major water tank waterproofing methods are:

  • Aquamat based waterproofing
  • Aquamat-elastic based waterproofing
  • Membrane sheet based waterproofing

 

Aquamat based waterproofing

This method is only used for under ground water tanks. A slurry of concrete is formed and then injected. The concrete used in this method is a specialized, it has high moisture absorbing capacity. The concrete used in this method withstands the dampness caused by the water and does not allow moles or crack to be formed.

The material is easily available. The overall cost depends upon the quality of the concrete being used.

This is traditional method of waterproofing a water tank, only the grade of concrete changes from time to time.

The durability depends on the material being used.

We recommend this method if you are low on budget.

 

Aquamat-elastic based waterproofing

This method is used for over head water tanks. In this method a mixture of cement concrete slurry and elastic material is mixed then injected or applied on the surface area’s of the tank.

The elastic material helps in contraction and expansion of substratum in case of temperature change. The durability is long and excellent in terms of other traditional waterproofing methods.

The cost is high and requires highly trained professionals for the process.

We highly recommend this method.   

 

Membrane sheet-based waterproofing

This method is majorly used for over head water tanks. In this method a thin sheet of polymer is glued on the inner or outer surface of the tanks.

The membrane sheets are available in the markets. It’s easy and quick method in case of emergency leakages.

The durability is long and everlasting. 

We recommend this method if can’t afford Aqamat-elastic based method and if you require a quick fix.
