Underground Chamber Sections

These tough, lightweight stackable chamber sections by Ultima offer significant weight and toughness advantages over traditional concrete sections. They are so easy to use that you can build any depth of chamber you want in just a few simple steps.

Available in a standard 1200 x 1200mm chamber size, the 150mm high sections are easily stacked to the desired chamber depth. They utilise a tri-wall construction for lightness and strength and are made in glass reinforced polyester for long term corrosion and chemical resistance.
