1 1/4 Minus and Bulk Aggregates for Lynden, WA

Ordering gravel and aggregate delivery in Lynden, WA usually starts with one question: what do I put under this? Washington Rock Supply sells bulk rock, sand and soil by the ton, and 5/8 minus is the surfacing course most drives, parking pads and shop slabs in this part of Whatcom County get built on.

On the Puget Sound lowland, rain perches on dense glacial till instead of draining away. That is why washed stone matters as much as base rock here.

Materials for Lynden Projects

Start with the washed sizes. Drain rock, also called 7/8 clean, is washed rock with no fines left in it, so it keeps open voids instead of packing tight.

That is what a footing drain, French drain, curtain drain or infiltration trench needs. Water sitting on till has to move sideways to daylight, and Drain Rock gives it a path.

For drywells and heavier drainage, #4 Crushed Stone is the larger clean stone.

4 as the alternative for gravel backfill for drywells.

Downspout runs and small drain trenches take a finer clean stone. 3/4" Crushed Stone is washed, so it drains rather than compacts, which suits trench backfill and pipe surround.

Then the minus sizes. 5/8 minus, also called crushed surfacing top course or CSTC, is crushed rock with the fines left in.

It packs hard and sheds water instead of soaking it up.

Below it goes 1 1/4 minus, or crushed surfacing base course. It has a larger top size and fewer fines, so it carries load and stays workable on soft wet ground.

Order 1 1/4 Minus under a 5/8 minus top course.

For garden paths and side yards, 1/4 minus packs down tight underfoot. Walkway Gravel is the fine end of the minus range.

Paver and flagstone bedding takes crusher dust, also called 3/8 minus or screenings. It is a minus product, so it compacts rather than drains.

Stone Screenings also fill joints.

Where a washed, fines-free stone is wanted in paver joints instead, use 3/8 clean. 3/8" Crushed Stone suits permeable paver setting beds and small drain runs.

Long rural drives and equipment parking take a driveway blend. Driveway Gravel is sold alongside the graded surfacing courses.

Ordering early in the week gives you room to work around the weather rather than through it.

Ground and Conditions in Lynden

The working season shapes the schedule here. The wet season runs October through April, and under the state stormwater manual for western Washington exposed soil has to be stabilized within two days in that window, against seven days in summer.

That is why base, paving and paver work gets scheduled for the dry months. Winter work means keeping the grade covered.

The ground itself is glacial. Across the Puget Sound lowland, the Vashon ice sheet left a dense till cap, its lower part hard enough that crews call it hardpan, over advance outwash sand and the silt and clay of the Lawton beds below.

Rain soaks the loose upper soil, reaches the till and stops. The water table then sits close to the surface all winter instead of draining away.

Anything built on till needs that water taken sideways to daylight. That is the whole reason footing drains and washed drain rock do so much of the work on this ground, and it is why a drive that was firm in August can rut in February.

Mild, wet winters mean the ground seldom freezes deep. It is saturation, not frost, that softens a base here.

What gravel is best for a driveway in Lynden?

It depends on what is under it. On soft or wet ground, 1 1/4 minus goes down first as the structural base, because it carries load and stays workable.

Then 5/8 minus goes on top as the surfacing course. It is crushed rock with the fines left in, so it packs hard and sheds water instead of soaking it up.
