Mountain Strong Concrete was founded by Kevin Martindale, a driver with Miles Sand and Gravel since 2006. After 11 years in the industry Kevin resigned his position in April of 2017 and purchased three 10-yard concrete mixer trucks.

Our goal is to supply the residential and light commercial finishing contractors with timely deliveries of ready-mix concrete products so you can get it into the forms, get paid and move on to the next project.

Based in Sumner WA, we deliver over 30 different mixes within a 40-mile radius (approx.) to meet any of your construction needs. We accept Visa, Mastercard, or cash.

A wise person once said; “It is better to serve one customer 100 times than to serve one hundred customers only 1 time.” We agree. We want to build strong and trusted business relationships, provide great products and services and do this for you over the long run. We are happy to coordinate with other independents to accommodate your larger volume pours.

"I wanted to let everyone know how wonderful and easy it was working with your team on a project I just finished up. The drivers were all very professional and great drivers getting around the tight site. They all showed up with the appropriate PPE and called when they were loaded and headed to the site. I will be using them again and have recommended them to several other companies."
