A well-deserved note to thank you very much for your time, expertise and assistance with our new Holland Paver Patio…Bottom Line: We are very happy with the new patio and my wife celebrated a friend’s birthday with a function for 10 ladies last week. Thanks again for your dedication to customer service for a very small project, it was really appreciated.

Mutual Materials was instrumental in providing a great color match and timely delivery of the product as well as resolving complex details where masonry was suspended overhead in the commons.  They were a great team player.

“Mutual Materials CMU enabled us the flexibility and freedom to achieve a contemporary building using a timeless material.  The Renton School District will benefit from the durability and maintainability of this material for years to come.”

The success of the design and installation resulted from a continuous balancing act between Sustainable and Streetscape design opportunities with the use of high-quality materials and construction details. Eco-Priora allowed us to meet both criteria.

“Classic Used Slimbrick is a “go-to” element for MOD Pizza because it adds an organic touch, giving new construction a warm, aged look.”

Living in a sensitive marine environment, we appreciate how well our Mutual Materials permeable pavers allow stormwater to filter through the soil instead of carrying harmful chemicals into the bay.

Even in a 100-year storm event back in December of 2008, the paver system installed allowed all the stormwater to filter through, reducing the risk of a sewer overflow into nearby Elliott Bay.

EcoStone not only addresses our water drainage issues, you’re also addressing the overall streetscapes in our community. The texture, the patterns and colors provide great scale for walkable communities and adds to the quality of life.
