New lightweight kerbstone revolutionise
pavements
Significant installation, cost and health and safety benefits of ACO Technologies' new LightWeight Kerb are set to change the way highway pavements are designed and constructed.
The significant installation, cost and health and safety benefits of ACO Technologies' new LightWeight Kerb are set to change the way highway pavements are designed and constructed Manufactured from polymer concrete - which is four times stronger than conventional cement-based concrete, the new stones present the same finished profile and in-situ performance as a HB2 kerbstone but weigh just 16kg compared with a 60kg traditional solid concrete stone

Queens Award double for ACO Technologies
ACO Technologies, has been awarded The Queen's Award for Enterprise: Innovation 2006 for its new, high-capacity surface water drainage product, ACO Qmax.
The 73% weight saving is achieved by a unique open rear face design.
This significantly reduces the volume of material used in its fabrication but does not impair its installed performance.
By allowing the surrounding backing concrete to fill the cavity, the integral strength of the kerb border is maintained, allowing it to be used for all HB2 highway and traffic applications.
Weight is further reduced and installed strength increased by the four elliptical holes in the lower front face.
These increase the bonding surface area and allow the backing concrete to completely surround the base of the installed kerb.
"Product weight and ease of handling are now critical issues for compliance with the HSE's new guidance on kerb installation," says Jon Croke, Technical Services Manager at ACO Technologies.
"This new stone is the lightest 915mm kerb available and meets all the latest health and safety criteria".
"Its unique shape makes it very easy to gain a secure hand grip and, as the material in the stone is greatly reduced, they are also easier to cut on site - a further significant safety benefit".
The lightweight system is also ideal for refurbishment projects.
As the overall height is just 200mm (255mm for a standard HB2 stone), old stones can be roughly broken-out and the new, shallower stones installed into a new bedding.
Following the same lightweight design principles, 915mm long left and right hand dropper stones and flush finish centres are also available.
"Feedback from contractors has now confirmed our findings from earlier site trials," says Jon Croke.
"As a result of the significant time saved in handling and transporting the new kerbs, contractors have found that they are able to install twice as much of the lightweight kerb over a typical day as they could with the traditional stones.".
