Frequently Asked Questions

Camplas GRP storage tanks are suitable for a wide range of liquids, including liquid fertiliser, AdBlue, de-icing fluid, potable and process water, and bulk industrial chemicals. Standard tanks, available from stock, are rated for corrosive liquids up to a specific gravity of 1.35. For higher-density or more aggressive products, Camplas engineers tanks to a specific gravity of 2.0, with the tank construction specified for the stored liquid. Refer to the Camplas chemical compatibility chart for individual products, or contact our technical team to confirm suitability.

Yes. Camplas manufactures GRP tanks to customer specification as well as to standard designs. Tank capacity and dimensions can be made to suit the available space, with flanged connections positioned to match the site pipework. Options include ladders, platforms and inspection hatches, and tanks are supplied in any RAL colour. Where the application requires it, Camplas also designs bespoke tanks, including insulated, bunded and double-skinned versions. Please see our Customised Tanks and Bespoke Tanks pages for further details, or contact our technical team to discuss your requirements.

GRP storage tanks do not rust. Unlike a steel tank, a GRP tank needs no protective coating, internal lining or cathodic protection, so there is nothing to maintain or renew over its life. GRP is also around a quarter of the weight of steel, which makes tanks easier and less costly to transport and install, and reduces the load on the base. Camplas GRP tanks are designed for a 25 year service life.

For large capacities and demanding duties, GRP outperforms polyethylene on three measurable criteria.

• Capacity. Rotationally moulded polyethylene tanks are typically limited to around 30 cubic metres as a single unit, whereas Camplas manufactures GRP tanks from 10 to 300 cubic metres.
• Strength. Polyethylene tanks are generally rated for specific gravities between 1.0 and 1.9, while Camplas GRP tanks are rated up to 2.0, with the glass reinforcement providing the stiffness required at large capacities.
• Service life. Polyethylene becomes brittle with prolonged UV exposure and is weakened by sustained storage temperatures above 37°C, whereas GRP with a UV-protective finish is highly resistant to UV degradation, and Camplas tanks are designed for a 25 year service life. For smaller capacities and light duties, polyethylene tanks remain a practical choice.

Whether a storage tank requires a bund depends on the liquid stored, the site and the regulations that apply to it. Secondary containment is commonly required for oil, fuel, liquid fertiliser and bulk chemical storage, and is not normally required for clean water. Camplas supplies tanks for installation within a concrete bund, with a fabricated GRP bund, or as self-bunded tanks with an integral 110% bund, so the appropriate arrangement can be specified for each site.
