Why is GRP Better for Water Storage?

GRP or Glass Reinforced Plastic is also commonly known as fibre glass. This material has a lot of advantages over other traditional materials that are used in the manufacture of water storage tanks. For the installation of a modern cold water storage tank there is no better choice than GRP. Here we explore why this is the superior material to choose.


Resistant to Corrosion

Steel has commonly been used as a material for water storage but the big downside to this material is that it will corrode and requires galvanising to prevent this. GRP, on the other hand, is corrosion resistant and can even withstand exposure to chemicals, wastewater and sewage if required.

High Strength Factor

Despite its light weight, GRP is also extremely strong. GRP outperforms traditional materials including aluminium in strength tests, making this material perfect for longevity.

Long Life

GRP one piece water storage tank will have a lifespan of 25 years, which is far greater than alternative materials. In this time the GRP will not need to be treated in order to maintain it so you won’t need to worry about coating or repainting it during its lifespan.


GRP is a very light material which has a range of benefits. Installation on roofs will require less reinforcement because of the lighter weight and heavy lifting equipment will not be required for installation. This can help to significantly lower the installation costs and can make it more practical to install a cold water storage tank in a wider range of properties without the need for crane access.

When compared to other materials used in the manufacture of water storage tanks, GRP is the clear choice to make. This lightweight, corrosion resistant and tough material out-performs other traditional materials in every test and will last for longer too. If you are considering installing a sectional water tank on your home then you should look no further than GRP tanks. To find out more or to request a quote, contact us today.
