Base Sections
Concrete base sections for manhole rings
Built to the highest standards.
AG concrete base sections for manhole rings are manufactured to comply with British Standards.
Units are equipped with six special ‘knock-out sections’ that cater for inlets at various angles. We keep standard 1200mm diameter base sections in stock.
Each base unit has a 150mm thick base which allows the customer to create their own benching with the use of the various knock-outs.
Availability
More Information
AG operates a Quality Assurance Scheme to these standards to cover all aspects of production.
All units are supplied with suitable lifting points.
A precast concrete manhole is a strong, durable structure with its own inherent strength and does not require a concrete surround at standard depths.
All units are manufactured and tested in accordance with BS EN 1917: 2002 and BS 5911-3: 2002 which, in addition to specifying dimensional tolerances, etc., clearly defines all the performance tests necessary to ensure that the product will perform satisfactorily in service.
Minimum order quantities are required for certain products and sizes. Before placing an order, please speak to one of our sales teams – they’ll be happy to advise on this and any other product questions you may have. You can reach them on 0121 747 0202 in UK and on +44 (0)28 8778 8112 in Ireland.
