Real treatment cost
Do not compare only price per litre. Compare the real bath cost.
A competing product may have a lower price per litre but require a much higher use concentration. With CORPOL, the concentrate required to prepare the bath may be up to 62.5 % lower than a product applied at 4 %.

Efficacy evaluated under real industrial conditions.
CORPOL efficacy was evaluated in Portugal on Pinus pinaster timber intended for pallet production. The trials were promoted by EMBAR and evaluated by LNEC, following CEN/TS 15082:2005 methodology with field-trial adaptations.
After 18 weeks, untreated timber showed attack levels close to the maximum of the evaluation scale. CORPOL-treated timber showed a very significant reduction in the development of blue stain fungi and moulds.
