Precast Concrete Seating Rings are available as either a single-piece or two-piece manhole riser. These standard, reinforced seating rings are 65mm deep and serve as alternatives to engineering bricks, adjusting ductile or cast-iron covers and frames to the correct level. They are certified to BS EN1917:2002/BS5911-3:2010 standards.
Features & Benefits:
- Quick and easy installation by semi-skilled labor, contributing to budget-friendly project management.
- Fewer joints minimize the risk of infiltration.
- One-piece units reduce the chances of onsite damage or theft.
- Each part of the two-piece unit weighs under 25kg, meeting manual handling requirements for a one-man lift.
- Single-piece and two-piece units are faster to install than traditional brickwork, eliminating the need for bricklayers, which saves time and reduces costs.
