HM Earthcare

The Product

HM Earthcare is a water soluble calcium polysulphide based reagent designed exclusively to be used to remediate a wide range of elemental contaminants at very low dosing levels..

Detailed studies, running thousands of scenarios have created empirical data to enable optimisation of the dosing for specific contaminants and matrices. The key advantages of using HM Earthcare are as follows:-

A permanent solution with studies proving irreversible reaction with accelerated ageing leachate tests of 100 years showing no loss of binding integrity.

Can be used in tandem with other remedial techniques.

Can be used with a broad pH range

Very low dosing levels required.

Numerous deployment methods available to match the site/job

Economical, giving ability to unlock previously untreatable sites.

Not only are the metals complexed but the ecotoxicolgy analysis reveals any metals still released (in trace levels) are in a non toxic form, thus there is no impairment of water quality.

Effective in all soils textures ranging from sand to fine silts and also built materials and slags.
