Slope Block

Universal. Affordable. Solid.

Concrete fill blocks are used “when you want to bring in soil or other surface material to make a levee or fill a cavity” – we even pulled a definition out of the dictionary for you. And, when they’re beautiful like ours, concrete Slope blocks can also be used to create low walls that have a lot of style. The Slope block, formerly known as the “Bloc Uni” at Patio Drummond, has proven itself over the years and remains the preferred choice of do-it-yourselfers and contractors.

Pro tip


The Slope block is manufactured with Hydrapel technology, which makes concrete products permeable and even more durable. When added to our drycast mix, Hydrapel reduces absorption, increases resistance to freezing and thawing and to weathering, and protects the concrete from UV rays.

The bearing capacity, or live load, behind the Slope block is greater than regular low wall blocks because it has 11 ½ inches of support. The wall can be raised to a height of 5 feet*. We recommend adding a foundation slab to your wall to further support the blocks. Installation is quick and easy: you won’t need a landscaper to install your wall, just a little preparation!

*To be confirmed with an engineer according to your project.
