 | | REINSTATEMENTSTILL GOING STRONG!

Highway material manufacturers are very good at shouting about how wonderful their materials are and how their use has benefited this and that project. And, it has to be said, in the majority of cases with good cause. Very few, however, take the bother to revisit the installation after a few years to review its performance and to determine whether the material has stood the test of time. But this is not the case with fast growing Tamworth based highways maintenance product manufacturer - the Instarmac Group plc.
Three years after Instarmac's BBA/HAPAS Approved Ultracrete Ironwork Reinstatement System was used in Dublin's extremely busy Parnell Road, representatives from the company returned to assess how the system was performing. They found that in spite of having been extensively trafficked by the City's one million inhabitants, as well as countless visitors, the reinstatement was still going strong with no inkling of failure.
In 2002, Dublin City Council decided to use Instarmac's system to reinstate a number of failed manholes. The Council approached Emtek Ltd, Ireland's highway specialist supplier, who recommended the use of Instarmac's fully comprehensive Ultracrete Ironwork Reinstatement System.
Each area was excavated and loose debris removed before Ultracrete M60, a rapid set bedding mortar was employed to bed a layer of new blockwork within the chamber. Ultracrete PY4, a polyester resin based mortar compliant with the tensile and compressive strength requirements stipulated in the Highways Agency Design Manual for Roads and Bridges HA104/02, was laid on to the blockwork as the bedding material for the manhole ironwork. Ultracrete QC10 was then used to backfill the ironwork and provide abase for Ultracrete Instant Road Repair cold lay surfacing macadam. Before the macadam was applied, however, the joints at the vertical edges of the road surface were sealed with Ultracrete SO to prevent future water ingress.
The Ultracrete Ironwork Reinstatement System has an anticipated service life of five years. By the way it is currently performing in Ireland; it can be expected to last a great deal longer than that.
