From the platform of laboring in the pineapple fields to Leading Concrete Contractors, Keith & Matthew Kaneshiro opened Universal Matrix, LLC April of 2012.  With the financial help from family and all their assets on the line, they started with a pickup truck, wheel barrow, some hand tools and their construction knowledge and have never looked back.


Our Mission

Universal Matrix offers you a one-stop shop for all your concrete construction needs. Whether your project is a small patio or a large commercial structure, we can handle it from start to finish. We use only the finest quality materials and adhere to all local and national concrete standards. Our emphasis on education, training, and proven concrete construction practices results in top-quality projects every time.

Our concrete project required patience and an immense amount of trust in the contractor we would select. When street parking became an issue, I decided it was time to start screening for a contractor with outstanding credentials who would execute our project in an attentive, timely, and creative way. Matthew Kaneshiro came to us with impeccable references and delivered high quality concrete work on our property. From our grandchildren enjoying bike riding around the house to parking cars easily, it has given us not only joy, but also a peace of mind! Thanks Matt!
