#4 Sand for Concrete, Catchment Liners, and Pipe Bedding

#4 Sand is a fine, clean sand best known for mixing concrete, but it earns its place in several other jobs around a Big Island property. In concrete work it provides the fine portion of the mix that gives the finished product its workability and smooth finish. Beyond the mixer, it is the standard dress or cushion layer placed under water catchment liners, a common and important need given how many homes on the island run on catchment.

It also fills a specific code role that coarser materials cannot. #4 Sand is the one material approved as pipe bedding for copper and ABS lines, because its fine, even texture surrounds and supports those pipe types without the risk of point damage that larger rock can cause. Placed beneath and around the pipe, it cushions the line and protects it from the stress of settling backfill.

As with any pipe bedding, the approved material and method are governed by code and are updated regularly, so confirm current local requirements before you use #4 Sand under a line. For concrete batching and catchment liner work, it gives a clean, consistent base that is easy to screed and level. It is a small-particle material that does a lot of quiet, essential work.

• Mixing concrete
