Large-format slabs can make a space feel cleaner without making the design feel empty.

Blu Grande from -bloc works especially well on walkways, patios and pool surrounds, where the larger format creates broad, uninterrupted surfaces with fewer visual breaks.

Contractor tip: with large-format slabs, pay close attention to transitions, edges and cuts. The cleaner the layout, the more intentional the finished space feels.

Swipe to see Blu Grande used across two very different outdoor spaces.

Where do you like using large-format slabs most: walkways, patios or pool decks?

A path does not have to be a solid ribbon of concrete. Borealis Stepping Stones from -bloc come in six shapes with a wood-plank look, so a route through a garden can wander, widen and settle into the planting instead of cutting straight through it. Spacing tip: set them a comfortable stride apart and let the greenery close the gaps.

The walls a crew is proudest of are usually the ones with the most corners. Mini-Creta from -bloc takes tight, straight-edged corners on a split-face block, so a curved seat wall or a multi-level bed comes off clean instead of forced.

Send us the layout and we will talk through the corner work.
