Salt treated with brine at depot or spreader BEFORE road application.

Two systems:

1. NaCl brine (23% saturated) — cheapest, extends working temp from -7°C (dry NaCl) to about -15°C
2. NaCl + MgCl₂ mix (typically 70/30) — works to -20°C, more aggressive, costlier (MgCl₂ is significantly costlier than NaCl)

We ship pre-wetted variants of both Sea Salt and Rock Salt deicing.

1. Working temp <-7°C — dry NaCl loses effectiveness; pre-wetted gets you to -15°C (NaCl) or -20°C (MgCl₂ mix)
2. Pre-treatment (anti-icing) — pre-wetted brine adheres + prevents ice forming; dry salt bounces into gutter (30-40% material savings)
3. High-speed sections — pre-wetted stays put under wheel turbulence
4. Bridges + elevated structures — freeze first, faster onset matters
5. Compliance — some EU + Nordic mandates pre-wetting on motorways (environmental)

1. Working temp >-7°C — dry NaCl is fully effective
2. Reactive (post-storm) treatment — once ice/snow on road, dry works fine
3. Open-spreader workflows — pre-wetted needs depot brine systems + closed spreaders
4. Cost-sensitive municipal contracts — USD 75-100/MT pre-wetted vs USD 65-85 dry

All major OEMs: Schmidt Stratos/Tarron, Epoke Sirius, Falköping Trans-Plus, Henke Buffalo, Aebi Schmidt CombiBack. Retrofitting brine tanks + nozzles is USD 8,000-25,000/truck — significant capex.

For 100 km highway pre-treated before 0°C / light-snow event:

Pre-wetted wins by USD 1,650/cycle. Over 100-cycle winter on a 100 km section = USD 165,000 savings. Pre-wetting pays back fast for pre-treatment workflows; for reactive treatment the math doesn't work.

See pre-wetted SKUs — both NaCl brine and MgCl₂/NaCl mix.
