What is a GRP Tank ? Johannesburg - South Africa

With more than 35 years experience in GRP, and we proudly, lay claim to the first GRP Tank in, not only Johannesburg but the whole of the Southern Hemisphere.


This was back in the late 80's day, when we answered a call from the Anglo American Corporation to develop an underground tank that wouldn't rust.


With one of South Africa's only GRP structural designer at the time -


Richard Holmes.


What is a GRP tank




A GRP sectional panel water tank, also known as a Glass Reinforced Plastic sectional panel water tank, is a type of water storage tank that is widely used in various industries and applications. It is a versatile and reliable solution for storing large volumes of water.


GRP sectional panel water tanks are constructed using panels made of composite materials, typically consisting of layers of glass fiber reinforced with polyester resin. These panels are manufactured using a process called compression molding, where the materials are combined and pressed together under high pressure and heat. This results in a strong, durable, and corrosion-resistant tank structure.

The panels used in a GRP sectional panel water tank are typically rectangular or square in shape, and they come in various sizes and dimensions. These panels are designed to be easily assembled on-site, allowing for flexible installation options. The tank's size can be customized to meet specific requirements, making it suitable for a wide range of applications, from small-scale residential use to large-scale commercial and industrial projects.





One of the key advantages of a GRP sectional panel water tank is its modular design. The tank is assembled by connecting the panels using bolts, nuts, and sealing materials. This modular construction allows for easy transportation, even to locations with limited access or tight spaces. It also enables quick installation and future expansion or relocation if needed.


The GRP material used in sectional panel water tanks offers several benefits. Firstly, it is lightweight compared to traditional tank materials like concrete or steel, making it easier and more cost-effective to transport and install. Secondly, GRP is highly resistant to corrosion, which ensures the longevity and durability of the tank, even in harsh environments or when storing water with high salinity or chemical content. Additionally, GRP has excellent mechanical properties, such as high strength-to-weight ratio and dimensional stability, ensuring the tank's structural integrity.

Another important feature of GRP sectional panel water tanks is their versatility in terms of configuration and accessories. The tanks can be designed with different compartments or partitions to store multiple types of liquids or to separate clean water from contaminated water. Various accessories can also be added, including manholes, ladders, level indicators, and overflow pipes, to enhance functionality and ease of maintenance.


GRP sectional panel water tanks are widely used in various industries and applications. In residential settings, they are commonly used for storing potable water in housing complexes, commercial buildings, or remote areas with limited water supply. In industrial sectors, such as agriculture, manufacturing, and construction, these tanks are used for water storage, fire-fighting systems, and wastewater treatment.


In conclusion, a GRP sectional panel water tank is a versatile and reliable solution for water storage. Its modular design, lightweight construction, corrosion resistance, and customizable features make it suitable for a wide range of applications. Whether it's for residential, commercial, or industrial use, GRP sectional panel water tanks offer a durable and efficient way to store and manage large volumes of water.
