Larsen Highways MBC 10 is a HAPAS-approved rapid strength concrete specifically developed for highway reinstatement works, carriageway ironwork backfilling and haunching applications. Manufactured from a controlled blend of specially selected cements, additives and aggregates, MBC 10 delivers exceptional early compressive and flexural strength, making it ideal for projects requiring rapid return to service.
Designed for use around manhole covers, access chambers and highway ironwork, MBC 10 provides a reliable and durable backfill solution that meets the demanding requirements of road maintenance and infrastructure projects. Its fast-setting formulation achieves initial set in approximately 15 minutes, significantly reducing installation times and minimising disruption to traffic and site operations.
In addition to highway reinstatement works, MBC 10 is highly versatile and can be used for post fixing, sign installation, fence erection, barrier installations and general concrete repair applications. The product can also be mixed to a trowelable consistency for bedding and patch repair work where a high-strength rapid-setting concrete is required.
