The type of sand to use for laying slabs depends on the type of slabs and the base material. Here are some tips from the search results:
-
Sharp sand: This type of sand is often used for laying slabs directly onto soil or grass. However, it breaks down faster over time.
-
Builders sand: This type of sand is often mixed with cement to lay paving flags.
-
Coarse sand: This type of sand is recommended for creating a base for pavers. It allows for a flatter surface, strength, and tight compaction.
-
Concrete sand: This is the best sand for creating a base for pavers as it helps set the pavers in place and makes them long-lasting and durable.
-
Polymeric sand: This is a blend of sand and special additives designed to fill the joints between concrete pavers and brick pavers. It is more expensive and requires more time and attention to detail, but it can reduce weed growth, resist rain washout, and help prevent insect penetration compared to traditional sand. It works best when used to fill the entire depth of the paver and on joints that are between ΒΌ inch and 1.5 inches wide.
In summary, the type of sand to use for laying slabs depends on the type of slabs and the base material. Sharp sand is often used for laying slabs directly onto soil or grass, while builders sand is often mixed with cement to lay paving flags. Coarse sand is recommended for creating a base for pavers, and concrete sand is the best sand for this purpose. Polymeric sand is a more expensive option that can reduce weed growth and resist rain washout, but it requires more time and attention to detail.
