Ironwork reinstatement

Rapid setting bedding mortars from Weber have been used very sucessfully for the last 30 years.


Road ironwork such as manhole covers, road gullies and duct covers need to be bedded with a resilient mortar to prevent the unit rocking or breaking up under traffic loading. Often the reinstatement of ironwork is done within traffic possessions under temporary roadworks and the time to reinstate is a critical factor.

1. Loose ironwork

Cracks in the pavement and movement of the manhole frame can result in the frame becoming loose. This results in the cover and frame ‘rocking’ and causing road noise as the unit is trafficked. The pavement begins to rapidly break up, causing failure.

2. Failure in the sand/cement bedding mortar

Site-mixed sand/cement bedding mortar cracks and crumbles under traffic loads, resulting in premature failure of the cover and frame.

3. Collapsed brickwork

Old brick chambers can collapse under traffic loads or become dislodged during reinststement works.


Use pre-bagged design mix bedding mortars

A detailed inspection of the ironwork needs to be done to understand the cause of the defect before reinstatement. Use pre-bagged special design mix bedding mortars for the reinstatement using fast and rapidsetting mortars.
