Limestone

When it comes to limestone, we have three types: #57, #8 and sand. Crushed limestone, or #57, makes an excellent base for driveways and parking areas because its angular pieces lock together well, creating a stable surface. The angular nature also allows water to drain through easily, preventing puddles or icy build up.

#8 on the other hand, features small, coarse pieces of limestone. The most common application for this gravel is a sub-base for driveways, sheds, retaining walls and paving projects. Gravel driveways can also have sunken sections filled up or topped over with this stone, helping create an even, smooth driving surface. The angular pieces resist shifting and compact well under tires over time.

Thirdly, limestone sand contains tiny fragments of crushed limestone. This material does not contain large pieces, perfect for sweeping sand underneath pavers or filling narrow gaps. The tiny pieces fill small voids completely, creating a substantial base for patios and walkways. Because there are not large pieces, the sand easily shifts into place as you compact the pavers above. This allows the pavers to lock tightly together, preventing shifting over many years of use.
