Pre-mixed concrete in bags is a quick setting cement used to concrete in foundation pins and gable ends.
- No mixing required (e.g. to mix with sand, gravel etc.)
- Just add water!
- How much cement do I require for the Polycarbonate Greenhouse up to 6m long?
You would require 4 bags of pre-mixed concrete.
If you require additional bags, you can buy them from under our accessories page.
