Bulk Aggregates for Patios in Matlock, WA

Washington Rock Supply handles gravel and aggregate delivery in Matlock, WA for two kinds of buyers: contractors building drives, pads and patios, and homeowners patching a rutted lane or bedding a walkway. Both usually start in the same place, with 5/8 minus.

Matlock sits in Mason County on Puget Sound lowland ground, where a dense till cap traps winter rain close to the surface. That shapes which materials work here and which ones do not.

Ground and Conditions in Matlock

Much of the ground across the Puget Sound lowland is glacial till with a hard lower layer crews call hardpan. Rain soaks the loose upper soil, hits that dense layer and stops, so the water table sits high all winter.

A thin base shows the problem first. The surface pumps, ruts and loses its shape long before the stone itself wears out, because water is sitting in it rather than leaving.

The fix is a base course that carries load above a drainage layer that moves water sideways to daylight. On till, drainage does as much work as the stone does.

The wet season runs October through April. Exposed soil has to be stabilized within two days in that window, against seven days in summer, so winter work means keeping the grade covered.

Winters here are mild and wet. The ground seldom freezes deep, so saturation softens a base rather than frost, and a drive that was firm in August can rut in February.

Materials for Matlock Projects

Bedding is where most patio and flatwork jobs are won or lost. Under pavers and flagstone you want a material that compacts tight and stays put, not one that drains away beneath the surface.

Stone Screenings, sold locally as crusher dust or 3/8 minus, is the fine end of the minus range and compacts into a firm setting bed. It is also swept into paver joints once the surface is down.

Where water needs to move instead of being held, the clean side of the range takes over. 3/8" Crushed Stone is washed and fines-free, so it keeps its voids for permeable paver joints and small drain runs.

Below a patio or slab, the structural course is usually 1 1/4 minus, also called crushed surfacing base course or CSBC. It has a larger top size and fewer fines than the surface course, so it carries load and stays workable on soft ground.

The Washington default surfacing course is 5/8 minus, also called crushed surfacing top course or CSTC. The fines are left in, so it packs hard and sheds water rather than soaking it up.

It suits driveways, parking pads and shed or shop slabs.

For anything that has to drain, Drain Rock, known locally as 7/8 clean or washed rock, keeps its open voids in footing drains and infiltration trenches. Rounded decorative stone is filed under round rock rather than crushed.
