What Clients Are Saying

We use the Washington Rock products for multiple places on the golf course, but the main thing we’re using it for is dilution of our thatch buildup that we have on the golf course. It provides a good environment for the microbial activity to break down the thatch that binds our fertilizers. We also use it on the greens to smooth out the putting surfaces, to make sure we provide premium playing conditions for our guests.

What Clients Are Saying

We had a long access road that we had to regravel frequently in the Puyallup Valley. The first time we obtained gravel from Washington Rock Quarries, they explained how properly sized gravel would stay in place longer. They suggested the right size, and it made a big difference. Very knowledgeable and great service. We could not be more pleased.

What Clients Are Saying

On a Washington State job, the numbers need to hit perfectly on the test. Washington Rock has been good about coming up with special mixes and working with us to get the right mix that architects or counties or cities are asking for. We get what we need, and everybody is happy.

- Steve Johnson, Project Manager for Teufel Landscape

What Clients Are Saying

Washington Rock’s crushed rock is some of the best in the area as it is very hard, which makes it more durable. It locks together to make a firm and unyielding driving surface. The compaction efforts are less than similar gravel because it is 100% fractured. It’s superior to most other products in the area.

- Dick Wall, Superintendent for Northwest Cascade

What Clients Are Saying

My experience with Washington Rock was extraordinary! They explained the difference in pea gravel size and what size would work best for our child’s playground. They delivered it when they said, maneuvering the truck into our backyard. I recommend this company for their integrity, excellence of product, and friendliness in customer service. I will absolutely use them again when we redo some of our rock fixtures in our yard.

What Clients Are Saying

We use Washington Rock’s sand for topdressing fairways and approaches. We really think it’s a quality product. We also have great customer service with our rep. It’s been a good relationship for us.
