Why we only sell two-cell block

Look at our 6" and 8" block and you'll see two cells, not three. Most VI builds have every cell reinforced and filled solid - the bigger cells are far easier to fill and to line up properly staggered, and the block is lighter to handle. Island Tough - why settle for less? Read more.

Two-cell concrete block

Sakrete - 30+ years

MSI has carried Sakrete for more than thirty years. Ready-mixed mortar and sand mixes give the same result batch after batch: no sand to pick up and sift, just add water.

Finishes

We keep Parex stucco primer and finish in stock - take the base next door to Sea Chest Ace and they'll tint it to your colour. The five most popular Diamond Brite pool blues are always in stock; other SGM colours arrive in about 10 days.
