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. Before placing an order, please speak to someone in our Civils sales team – they’ll be happy to advise on this and any other product questions you may have.
