Does SFZL sell concrete blocks?
No, SFZL only sells the molds used to make concrete blocks and related items. SFZL does not sell the concrete blocks themselves.

You can use the table below for a general estimate, but keep in mind that no two situations are the same and that the actual outcome may differ.
How long does the concrete take to cure/dry?
The recommended cure time of a concrete block is 24-48 hours, depending on the type of concrete used and local conditions. Larger products requiring more concrete, such as tetrapods, have a longer cure time.
On what surface can I cast concrete?
We recommend casting concrete on a clean, level surface. We recommend using a casting table with adjustable legs if necessary to create a flat, level surface.
Can I buy now and pay later?
No, unfortunately SFZL does not offer this option.
