Fill – Hardpac 3/8″ Minus Crushed Limestone Fines

Limestone fines from Pelican Point can be an ideal choice for placement in applications such as footpaths or other trails where a smaller top size would be ideal.

Fill – Structural A-1-a fill graded to a 2” minus

Structural A-1-a fill graded to a 2” minus.

Rock – Boulders

Angular boulders for use in retaining walls, water features or other landscape improvements.

Rock – Unwashed, 1.5″ Maximum

Used for many of the same functions as the smaller diameter ¾” Max rock, but where a coarser rock is specified or desired.

Rock – Unwashed, 3/4″ Maximum

Used for various backfill and bedding applications as well as underneath concrete slabs or ground cover for gravel driveways, this angular and durable rock meets a core need on many construction projects.
