GRP Storage tanks

From experience we know that every application has its own specific requirements. Polem GRP storage tanks include detail engineering, manufacturing, transportation and installation of all components. Polem offers a wide range of diameters, volumes and accessories. GRP storage tanks from Polem have excellent properties ideal for storing fluids at industrial plants. Due to the application of GRP material, Polem GRP storage tanks are chemical and corrosion resistant, can be designed for high abrasive resistance and be used in highly aggressive environments, operating at temperatures varying from -40°C up to +120°C. Polem designs a ‘chemical barrier layer’ on the inside of the storage tank making the product state of the art in its class.

As an experienced supplier to industrial markets, Polem is able to start up each project including design and engineering for the customer with advanced CAD software and knowledge of all quality standards in these markets. In addition to that, Polem has excellent standards for quality by being a certified partner. The project managers at Polem ensure each individual project will be executed with care.

Why you should choose a Polem storage tank:

  • Excellent chemical resistance
  • Excellent corrosion resistance
  • Excellent abrasion resistance
  • Suitable for extreme temperatures
  • High mechanical strength
  • Certified by national and international organisations
  • Economical benefits, long lasting solution
  • Turn key supply
  • Tailor made solutions
  • Horizontal or vertical storage tanks
  • Underground storage tanks
  • Large diameter storage tanks

Applications for of Polem GRP storage tanks:

  • Storage of chemical fluids (HCl, NaOH, Naocl)
  • Storage of water and waste water (drinking water, cooling water, seawater, sludge, slurry)
  • Storage of petrochemical or organic fuels
  • Storage of liquid fertilizers
  • Storage of oils or food components


Should insulation be required, it is a simple task to equip the silos and tanks with a 50 mm PU foam layer covered by a 5 mm GRP layer. This method of insulation produces a K value of 0.5 W/m2K. If needed the thickness can be adjusted, for example to 100 mm PU foam (0.3 W/m2K).

Benefits include:

  • 100% resistant to any kind of weather
  • Easy to apply at the factory;
  • No additional on-site costs
  • Cost-effective


  • Cage ladders
  • Platforms
  • Guard rails
  • Walkways
  • Heat tracing systems
  • Reinforcement / vacuum rings
  • Platforms or anti slip (or skid) layers
  • Pumps
  • Valves
  • Level indicators
  • Load cells
  • Agitators
  • Agitator bridges
  • Dust filters
  • Double wall construction or constant monitoring on the tank (PDS)

Sustainability and innovation

Life Cycle Analysis* studies have shown that production with composite materials uses less than half the energy when compared with metals, alloys and concrete. Production costs and maintenance prove to be considerably lower in comparison with standard materials.
