How thick should pavers be over concrete?

To effectively distribute weight and prevent damage, pavers must be at least 2 inches thick, especially if more than one person crosses them at a time. Saving money by using thinner pavers generally causes cracks in those cobblestones, and cracks allow weeds to escape and populate the cobblestone walkway. Do you need something to pave a walking path with? The Slimline 40 mm paver is made exclusively for pedestrian areas. You'll want to use 40 mm on sidewalks, patios, and any other area that's only used for foot traffic.

These thin pavers are also ideal for use as decorative cladding on an existing concrete patio that won't see traffic, except for the occasional cat in a flower bed. Western Interlock has a pair of 40mm pavers, including Slimline Holland and Slimline Cobble. The process of placing pavers on concrete is the same as placing a cobblestone patio above the ground. Paving stones can be installed on concrete without mortar if a layer of sand between ½ and 1 inch is first placed.

A thick base is highly recommended for a durable cobblestone path. The typical cobblestone base should be about 4 to 6 inches thick. It should consist of a layer of crushed concrete mixed with an earthen base. Arguably, the base of the cobblestone is as important as the cobblestones themselves.

Traditionally, entrances have been constructed with 80mm pavers with a standard six-inch base. Nowadays, common practice employs a 60 mm paver with a thicker base. The thick base is especially critical in a rainy climate with clay soils. You'll quickly discover that a paver that's too light for the space you're placing it in won't be structurally strong enough to stand the test of time.

But pavers are best for the border because they provide a flat, even surface for flattening (see photo). Using mortar to install pavers is also a very common method, but it's important to say that mortar setting is not recommended when placing pavers on asphalt, since asphalt is too flexible and can break mortar. Cobblestone joints can also break if the stones you choose aren't right for the area and end up attracting more traffic than they were meant to handle. Some contractors want to install pavers to determine the surface area that will be needed for the cobblestone pattern they need to install.

Most cobblestone installations come with a lifetime warranty because they last for decades with minimal repair costs. The elegant elegance of cobblestone entrances has led contractors to copy their look with stamped concrete. Measure the depth of the base of the cobblestone and add more crushed stone until you reach the desired depth of four inches. Covering concrete with pavers is much easier than pouring new concrete or laying pavers in the traditional way.

Consulting a professional paver will always ensure that you get an authentic and elegant paved road with improved property value and a lifetime warranty. To prevent sand and cobblestones from settling and crushing, a concrete slab cobblestone patio must be firmly edged. This is the minimum thickness to correctly distribute the weight over the pavers, especially if there is going to be more than one person in the yard at a time.
