    All our GRP Sectional tanks are for delivery by customer offload. This entails the customer to acquire the right manpower and/or machinery to help unload the tank/s from the delivery vehicle.

    Assembly Zones

    On Site assembly by a nationwide network of highly trained engineers, enabling us to get to you no matter where you are. Hand-picked by the manufacturers of the GRP Tanks themselves.

    Having your Sectional tank assembled on site saves all the hassle of piecing the tank together, being cost-effective and also validating the warrantee.

    Another process to save time and worry is to have your new sectional tank cleaned once installed. This process is normally put on the back burner, however once an engineer has entered the tank, drilled holes, set the tank up, the tank has contaminants within it which can harbour harmful bacteria, so it's a good code of practice to get the tank cleaned once assembled on site. You can select this option above, or you can contact us for a quote.
