Sand is one of those materials that people tend to treat as interchangeable until they use the wrong one and run into problems. There are several distinct types in common use across construction and groundwork, and the differences between them matter more than most people expect. Here at NWTH, we can help you find the right sand for your needs and deliver it to site.
Sharp sand is the one to reach for when strength is the priority. It has a coarse, angular texture that binds well under pressure, making it the right choice for concrete mixes, floor screeding and block paving bedding. If your project involves anything that needs to carry load or set firmly, sharp sand is almost certainly what your specification calls for.
Building sand sits at the other end of the texture scale. It’s softer and finer, which makes it far more workable for bricklaying, pointing and render applications. It won’t give you the structural properties of sharp sand, but for mortar work it handles beautifully and produces a cleaner finish. The two are sometimes confused because they look similar in bags, but they behave quite differently in use.
Fill sand occupies a different role entirely. It’s a fine, smooth material used primarily for backfilling trenches and levelling ground rather than structural applications. Its value lies in how easily it compacts into awkward spaces and around underground infrastructure without creating voids or uneven pressure points. It’s not a substitute for sharp sand in a concrete mix, but for the jobs it’s designed for it’s hard to beat.
Washed grit sand, such as WSA 3mm, is a recycled aggregate option that covers a useful range of applications including paving slab bedding, plastering and drainage. It’s processed to consistent standards under the WRAP Quality Protocol and performs comparably to quarried alternatives across most standard uses, often at a more competitive price.
Choosing the right sand comes down to understanding what the material is actually being asked to do. Aggregates suppliers with experience will point you in the right direction before you order rather than simply dispatching whatever you’ve asked for. If you’re not certain which type suits your project, it’s always worth a conversation before anything is delivered to site.
