Ultracrete’s QC10 F flowable concrete has been used to carry out track repairs to a section of the LUAS tram line in Dublin.  

The Luas is a state of the art Light Rail transport system in Dublin, providing passengers with a high-capacity service that is fast, frequent and reliable. It opened in 2004 and currently has 54 stations covering 23.7 miles of track, carrying approximately 30 million passengers a year.  

A section of embedded track concrete shoulder, adjacent to the road surface, was under stress because the installation material had failed. Ultracrete recommended the use of its QC10 F flowable, fast set, rapid strength concrete to resolve the issue.  

It is specifically formulated for back filling around ironwork (and composite), including gullies and manhole frames and can also be used for surface repairs. It requires only the addition of water on-site to form a high strength concrete, achieving a compressive strength of 20N/mm² after just 90 minutes! It sets in 10-20 minutes and is suitable for applications from 30-250mm in one pass.  

In this instance it was used as a surface repair and was installed by maintenance contractor Civic Group Ltd, who carried out the reinstatement overnight during a tight time frame of just four hours, to ensure minimal disruption to the tram and its commuters. Existing material was broken out, before QC10 F was poured into the void around the girder rails. The site was re opened within the allotted window thanks to the material’s rapid setting properties.  

QC10 F is HAPAS approved by the BBA as part of Ultracrete’s manhole reinstatement system which is independently tested by a UKAS accredited laboratory to verify its performance. The system comprises of a range of bedding mortars, back fill concrete, cold lay asphalt and a bitumen spray.  All components offer, where appropriate, impressive tensile and compressive strengths thus prolonging the service life of the repair.
