The products have been used for a number of manhole reinstatements across West Malaysia. Indah Water Konsortium (IWK) is a national sewerage company in Malaysia. Government owned, IWK is responsible for developing and maintaining a modern and efficient sewerage system for West Malaysia.
In Malaysia, the current system for installing ironwork involves a manhole cover precast in a concrete block positioned on to the repair site, a costly and time-consuming method. Doing the job this way means that heavy equipment is needed to set the concrete block in place.
One of the biggest disadvantages of using this method is the concrete block remains rigid and does not move with the surrounding road surface, causing the repair to crack and break out. Not only does this require costly repeat visits to site but it also causes a dangerous safety hazard to motorists, a major concern for IWK and a key factor for the firm sourcing an alternative method for reinstating manhole covers.
Protasco Trading recommended the use of UltraCrete Envirobed HA104 high-performance bedding mortar, QC10 F rapid set flowable concrete and Instant Road Repair cold lay asphalt for all future reinstatements.
UltraCrete offers products that are proven, trusted and provide a first time permanent repair in all climates and weathers. Part of UltraCrete’s Manhole Installation System, Envirobed HA104, QC10 F and Instant Road Repair have each been tested and had their capabilities proven by an independent laboratory stating that this system will have a minimum five year service life. As no large machinery is required, the installation process is easier and quicker than existing methods.
Manholes reinstated with UltraCrete’s system can be trafficked instantly, allowing costly traffic management to be removed quickly with minimal disruption to motorists.
The repairs were carried out earlier this year in temperatures as high as 29ºC. High temperatures like these can pose a number of challenges for contractors as products often set very quickly but thanks to the expert formulation of UltraCrete materials this was not the case and the repairs were completed successfully.
