Highways MBM 104

Larsen Highways MBM 104 is a HAPAS approved two component, rapid setting cementitious mortar for the bedding of street and highway ironwork conforming.


It is manufactured from a controlled blend of specially selected aggregates, cements, additives and special polymers to produce a high quality bedding layer with exceptionally high early compressive, flexural and tensile strengths compliant with Department of Transport DMRB HA104/09.

MBM 104 provides all the benefits of a resin based mortar with the ease of use and disposal of a cement based mortar. It is ideal for the rapid installation of Highway and residential manhole cover frames and similar ironwork drainage components.
