Why Masons Choose Block Shear
PICK YOUR MACHINE
Which Splitter Do You Need?
Start with the material. For natural stone like limestone, sandstone and granite, choose the Stone Splitter, which takes stone up to 8.25″ high and 18.25″ wide. For wide slabs, treads and large format pavers up to 24.5″ wide, step up to the Stone & Slab Splitter.
For concrete products, choose the Masonry Block Splitter. It is the block splitter hardscape crews use for pavers, retaining wall block, concrete block and precast. For brick, thin veneer and soft stone, the 90 lb Mini Stone Splitter is the compact brick splitter that goes anywhere.
Every model comes in manual hydraulic, which needs no power or air, or air-assist hydraulic, which runs off a compressor for faster cycles. Not sure? Ray will talk it through with you.

After using the Blockshear stone splitter effectively for almost 5 years the only issue I had was a broken hose. The hose was not defective, it was cut while in transport. I called Ray at block shear for advice on how to fix it. Instead of advising me he immediately shipped out a replacement hose at no cost! Not only are the machines at Blockshear amazing, the service is second to none! Thanks Ray!
