world-eHello everyone,
How did you install or have your concrete patio slabs installed? With or without edge restraints such as curbing, edging strips, etc.? Our patio slabs will have a thickness of 42mm (1.65 inches). I imagine it would be difficult to install them without edge restraints and then secure the outer row with concrete or create a concrete wedge. There would only be about 20mm (0.8 inches) of space if the concrete wedge is intended to be slightly covered with topsoil later. Grass would probably have a hard time growing there. However, this approach could save the effort of installing the edging stones. In theory, you can position the edging stones so that the slabs fit in without needing to cut them. But I am not sure how well that works in practice.
What are your opinions or experiences? Possibly even with photos showing patios without edge restraints.
Thank you very much

No, it looks cheap with a concrete wedge. I don’t think it looks cheap without any edging. However, the terrace slabs would probably need to be thicker to allow for a concrete wedge and still have enough soil on top.

Vicky Pedia22 Jul 2020 17:10You could use lawn edging stones as an edging. With a 10cm (4 inches) rooting depth, you can cover about 15 to 20cm (6 to 8 inches) above that, allowing grass to grow. There are also other types of edging stones (with flat tops) and 30cm (12 inches) high. Alternatively, you can lay the last row of paving slabs in a mortar bed (the mortar must be suitable for outdoor use). In many regions, there are so-called "show gardens" where manufacturers display their products.
