Best Manhole Bedding Mortar 2022

27 FEBRUARY, 2022

Whether you are a utility contractor, surfacing contractor or any highway maintenance organisation, it's essential that you choose a high quality reliable rapid setting manhole bedding mortar.

There are a number of key things to consider when choosing the most appropriate manhole bedding mortar.

Timescales

Depending on the application and circumstances of the project you are working on can choose;

MBM30
30 Minute Mortar

30 minute mortar, reaching 20 MPa within 30 minutes

60 minute mortar, reach 20 MPa after 60 minutes

90 minutes mortar, reaching 20 MPa after 90 minutes

Shelf Life

It's important to select a bedding mortar which has a minimum of a 6 month shelf life. This means the product will remain workable and to the highest quality 6 months after the manufacture date.

Coverage

A 25kg bag of a good quality bedding mortar should provide 1m2 of coverage at 12.5mm thick.

Rapid setting mortar should not be used in layer thicknesses of greater than 75mm.

Working Time

When working with repaid setting mortar, its important to remember that due to the high content of cement within the mix, the period in which the product remains workable after adding water can be quite small.

MBM 30 will remain workable for 10 minutes before setting

MBM60
60 Minute Mortar


MBM 60 will remain workable for 15 minutes before setting

MBM 90 will remain workable for 15 minutes before setting

MBM 104 will remain workable for 20 minutes before setting

Cost

To attain the most cost effective pricing for rapid setting mortar, it is important to purchase in pallet quantities, minimising the impact of the ever increasing cost of transport and logistics per bag.
