Concrete seating rings are reinforced 65mm deep units which can be used in place of engineering bricks to adjust the ductile or cast iron covers and frames to the required level. Manhole seating rings are also often a much cheaper and more convenient choice.
They can be quickly and easily installed by semi-skilled labour and there are fewer joints which reduce the likelihood of infiltration. Our multi-part adjusting units offer the advantage of light weight sections enabling one man to handle the units.
