I've been purchasing septic tanks from Bonner Concrete for years for my excavation projects, and I’m always impressed by the consistent quality of their products. The concrete tanks are well-made and built to last. On top of that, Dave and Tracy and the rest of the team are fantastic—friendly, knowledgeable, and always provide excellent customer service. It’s a pleasure doing business with a team with integrity, that stands behind their work. Highly recommend Bonner Concrete!

I've had the pleasure of dealing with the team at BCPI while developing my property. They've been immensely helpful, with all the information, details and specs needed prior to ordering, down to rapid, courteous delivery by the owner (Dave) himself! We've purchased concrete fence blocks and a 2500 -gal water tank and will be doing more business together as the project evolves. If you need precast concrete products for your project, BCPI should be your first choice! Highly recommended.

Amazing customer service! Competitively priced, great inventory, knowledgeable and helpful staff. Hands down best place for concrete products!

Absolutely professional people and thorough! The ladies taking your order are knowledgeable and patient when I'm stressed out and forget something! And Jake the delivery guy is Johnny on the spot and gets it done! Fit tanks into tight places for me! Prices are fair and competitive and I'm a lifelong customer! Scot Palmer, Owner HV Contracting, Complex installer!!
