Breakthrough in cement based technology

Instarmac Envirobed HA104 new high strength, rapid setting cement based mortar is wholly environmentally safe, as well as being able to meet very tough highway specifications.

Envirobed HA104 - 'The next generation' of sement technology, now with full BBA/HAPAS approval.

One of the most potent issues of our time is that of the environment and one material manufacturer who has been keeping its finger firmly on the pulse of market developments in this respect is Tamworth based Instarmac Group plc.

In spite of already having an extremely successful material with which to bed-in ironwork covers and frames, Instarmac has developed and launched an entirely new high strength, rapid setting cement based mortar.

The new material is wholly environmentally safe, as well as being able to meet very tough highway specifications.

It is set to completely change the means by which, and the materials with which, future ironwork covers and frames will be installed.

Instarmac's new Ultracrete Envirobed HA104 is based upon the very latest cement technology.

The revolutionary, cutting edge material is the forerunner of the next generation of environmentally friendly alternatives to resinous-based materials for the bedding of ductile ironwork conforming to the DTI Design Manual for Roads and Bridges 'Mortars for bedding ironwork to BS EN 124'.

Envirobed is now fully approved by BBA/HAPAS as part of Ultracrete's Ironwork Reinstatement System (certificate number 05/H104).

The advantages provided by the new high strength, rapid setting cementitious mortar are numerous.

As well as conforming to the most recent Highways Agency Specification for Roads and Bridges: HA104/02, which up until now has eluded cementitious mortars, Ultracrete Envirobed HA104 does not have any of the inherent environmental disadvantages of polyester resin based materials, which previously were the only products able to conform to the specification.

The material can also be used in wet weather, thus reducing the likelihood of cost increases cased by Section 74 penalties and traffic disruption caused by inclement conditions.

It is believed to be the only cement based bedding material able to develop the required compressive and tensile strengths specified, thereby ensuring roads are not closed for lengthy periods and labour costs are kept to a minimum.

In order to satisfy the guaranteed performance demanded by the Highways Agency specification, mortars must be non-shrink, able to achieve a compressive strength of 30N/mm and a tensile strength of 5N/mm after three hours, as well as a minimum workable life of fifteen minutes.

Uniquely, Ultracrete Envirobed HA104's tensile strength is about twice as high as that of other fast setting cementitious mortars.

It is much less hazardous than the traditional polyester resin based materials and there are no 'special waste disposal' costs with regard to the disposal of the used packaging.

Envirobed HA104 is also part of a full Instarmac system for bedding ironwork covers.

As such, it eliminates any possibility of split liability disputes often experienced when separate proprietary products are employed.
