Thawrox -plus 

Thawrox+ is an innovative combination of rock salt and a natural agricultural by-product. It is designed with clear measurable operational and environmental benefits. Not only does it improve spreading efficiency and increase resilience, Thawrox+ also helps reduce corrosion to both vehicles and infrastructure.

What is Thawrox+?

Thawrox+ is a 6mm rock salt that has been premixed with an agricultural by-product - a derivative of sugar production called Safecote®- which has powerful anti-icing, de-icing and corrosion inhibition properties.

What makes it so effective?

Proven product for anti-icing and de-icing

Agricultural by-products have been used successfully in North America for more than ten years. The additive Safecote has been used in conjunction with rock salt in the UK for over seven years. Thawrox+ is ideal for precautionary salting during periods of cold weather.

An even flow

Rock salt can be prone to bridging and tunnelling in vehicle hoppers, leading to problems with spreading. The special additive that coats the rock salt particles makes it flow evenly through the vehicle hopper, with little or no clogging to spinners and chutes.

Greater efficiency - greater resilience

The spread pattern is more efficient as the additive binds the finer rock salt particles together - this helps reduce wind borne loss and also cuts down bounce off in the larger particles. As a result, the spread pattern is more efficient, offering greater spread widths and up to 30% reduction in salt usage. What's more, with reduced spreading, vehicles do not need to return to the depots so often, so spreading routes can be optimised, overall operational costs can be reduced and resilience increased.

Reduced costs and less salt metal corrosion

Although Thawrox+ is a premium product, it still offers a number of cost benefits - far outweighing savings that may be made using an untreated salt product. These benefits include:

  • good adhesion to the road, keeping the surface damp for several days
  • significant metal corrosion protection - the life expectancy of spreading vehicles can be increased with continued use of Thawrox+. Customers who have used pre-wetted technology for longer periods have found the life expectancy of a spreading vehicle chassis can be reduced by at least two years
  • less freeze/thaw damage to carriageways
  • reduced salt corrosion of street furniture such as streetlamps and road signs - cutting down on maintenance and capital costs
  • less wash-down time for the spreading vehicles

Easy to use

Despite the innovative nature of the product, no specialised equipment is needed to use it – so there is no additional capital outlay required.

Greener solution to de-icing

In addition to all the practical and economic benefits, Thawrox+ is better for the environment too. Owing to the additive deriving from a food grade renewable source, it degrades easily and as less of the product is needed, the amount of chloride entering the environment in the first place is significantly reduced.

Appendix H

The use of treated salt is referred to in Well-maintained Highways - Code of Practice - Appendix H, with reports of reduction in spread rates, better retention on the road surface and savings in salt usage.

Don't just take our word for it...

Local authority customers across the country are already very impressed by Thawrox+'s proven capability and have been using it for several years.

Derek Twigg, Strategy Development Manager (Highway Operations) Transport programmes and standards, Hertfordshire Highways, says,

"Treated salt has been a major factor in our ability to be confident to reduce spread rates and potential outings during this winter season. Proven in its use to deliver effective treatment at a reduced spread rate of 8g/m2 and 15g/m2; against traditional methods at 10g/m2 and 20g/m2."

"Residual salt level indications have allowed consecutive outings to be reduced and as a result we have increased likely environmental benefits of fuel reduction and reduced long term effects of traditional salt on street furniture and the surrounding environment."

Mike Bosworth, Team Manager, Dudley Borough Council, says,

"We have found Thawrox+ to be very effective with less tonnage needed - because the salt stays where it is needed. And it is more environmentally friendly, because less salt is needed to do the same job."
