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.
