Pozzolan: Argical M-1000

Achieves a hydraulic set in traditional lime putty mixes. Pozzolans can offer some protection against frost Using a pozzolan is beneficial when using lime putty mixes in damp, frost prone or exposed locations. Adding Argical to lime mixes increases compressive strength, therefore offering additional protection during the slow carbonation period. Historically, volcanic ash, brick dust and other forms of burnt clay were used as pozzolanic additives in lime mixes. Argical M-1000 is a metakaolin which we use today to have the same effect. The term pozzolan originates from the Italian city of Pozzu

Where this comes from

The part other shops don't tell you. Three separate questions, kept separate on purpose, each with its source.

UK company
Registered at Companies House as MIKE WYE LIMITED, number 06510748. Checked 2026-08-29.
Means the business is a British legal entity, not a British-sounding name owned elsewhere. It says nothing about where anything is made.
UK operations
Not yet checked.
Means people employed here, or premises they actually work from. We keep this separate from the company badge because a registered office can be an accountant's spare room, and a company can be registered in Britain while everything it does happens somewhere else. Where we have not looked, we say so rather than assuming.
British-owned
Not established. Many companies file a statement rather than naming a controlling shareholder.
Read from the register of people with significant control, following the chain of holding companies. It does not gate anything: a firm can be made here and owned elsewhere, and that is worth telling you rather than hiding.
Where it is made
The maker doesn't say, so neither do we.
This is about the individual product, not the company. A British firm can sell things made abroad, which is normal and not a criticism. We would rather tell you which is which than average them into a score.
