GRP (Glass Reinforced Plastic) cold water storage tanks are widely used across commercial buildings due to their durability and corrosion resistance. However, ageing components, poor maintenance and changing regulations mean many systems now require professional attention.

At Express Water Tanks, we specialise in GRP cold water tank repair and replacement for commercial and public sector buildings nationwide.

Why GRP Tanks Still Require Maintenance

Although GRP tanks are long-lasting, key components such as seals, panels and access hatches can degrade over time.

Common GRP Tank Issues

  • Leaking sectional joints
  • Cracked or damaged panels
  • Failed or poorly sealed access hatches
  • Inadequate insulation or screening
  • Contamination risks

We provide:

  • Chlorination of tanks and pipework
  • Byelaw upgrades
  • Cross-flow installations
  • Full compliance support
