UltraCrete Envirobed HA104 bedding mortar and UltraCrete QC10 F rapid set flowable concrete have been used to reinstate three failed manhole covers and frames at Weeze Airport in Germany.
Weeze Airport, formerly known as Flughafen Dusseldorf-Niederrhein Airport, is located in the Lower Rhine region of Germany. A former military airbase, Weeze Airport began operations as a civil airport in 2003 and regularly sees 2 million passengers using its services each year.
A number of manhole covers and frames had become damaged on one of the airport’s platforms and required urgent attention. Instarmac’s partner in the Netherlands, Poltec, provided the products for the repairs.
As the a leading manhole reinstatement specialists in the Netherlands, Poltec’s contracting division, PST van den Broek, carried out the repairs efficiently thanks to the high performance and rapid setting nature of the UltraCrete materials.
UltraCrete Envirobed HA104 is an environmentally friendly alternative to resin-based mortars and has been specifically formulated for the bedding of all access covers. It boasts superior compressive, tensile and flexural strengths, which make it ideal for use in heavily trafficked/wheel track locations, such as those at Weeze Airport. What’s more, repairs made using Envirobed HA104 can be open to traffic after just 1 hour.
Part of UltraCrete’s range of high specification concretes, QC10 F is a rapid setting, fibre modified concrete formulated for the backfilling around manhole frames and gullies. QC10 F has a strong compressive strength and can be opened to traffic in just 90 minutes.
Both Envirobed HA104 and QC10 F have been independently tested and approved by the Highways Authority Product Approval Scheme (HAPAS) for over 10 years and are proven to provide first time, permanent and durable repairs with a service life of at least 5 years.
