Chambers

Concrete chambers are used to ‘protect’ and ‘house’, valves and hydrants. Chambers are constructed around the fitting to the required depth in 100mm increments, utilising interlocking sections. Top sections allow for correct positioning and installation of surface boxes. For larger concrete chambers see Rectangular Chamber Sections in Surface Water Drainage section. For large Modular Chambers see Ducting Systems section.

Features & Benefits
  • Strength and rigidity from interlocking construction
  • Easy to handle units
  • Minimal labour skills required
  • Variable depths simply achieved
Applications
