Install once and protect, not twice and regret

Manhole covers and gully grates without Armadillo protection

It's a common issue that ironwork intended for vehicles with pneumatic tyres can become damaged by heavy plant during a construction project. Working with customers across the country we have developed a cost effective and easy to use solution to this age old problem.

Manhole covers and gully grates are often installed during the early phases of a construction project. During this phase ironwork is exposed to extreme loads from heavy plant including, tracked vehicles, forklift prongs, digger buckets and more.

Cover and gratings installed in these situations were never designed to accommodate these scenarios. This can result in premature failure and additional costs in materials and labour to put them right before handover.

In addition, gully grates can often become clogged with silt and debris which can cause severe issues for the drainage system and the water course. This can result in high cleaning and maintenance costs, residual issues from long-term debris ingress and potentially significant fines.

Armadillo is tough...
Really tough

Armadillo provides protection from loads up to 60 tonnes*. That’s more than enough protection from on-site construction machinery, ensuring that your ironwork will remain intact.

Additionally, Armadillo is designed to be reused on future sites, so you can gain the benefit of this protection again and again. But equally, Armadillo is designed to be sacrificial and can be completely recycled.

Solve these issues and more

Get the right protection at the right time

Manhole covers and gully gratings are one of the first materials installed on a construction site, usually selected to suit the final traffic environment (Group 4 D400, pneumatic tyres). However, during the construction phase, they can be regularly exposed to much greater forces from tracked plant and machinery. This is a common cause of premature failure.

Remove the need to replace damaged ironwork

Jet washing or sucking out gully pots can be costly, but failed ironwork can cost thousands of pounds to completely replace.

However, the costs don’t just stop with the materials and labour. There are many other costs related to the issues of failed ironwork including health, safety, environmental, project delays and disruption to residents.

Save time and reallocate resources

The task of replacing failed ironwork can be time consuming. But the overall time is just one small aspect of it.

The inconvenience can include having to reallocate resources, plus the additional time required to allow for bedding mortar to cure or set before the ironwork can be trafficked.
