Many people find patios, pathways and even driveways more attractive when built from interlocking pavers. Pavers often create an old-fashioned stone look. If you'd like to install a patio or path with pavers, follow these steps.
Step 1 – Plan
Installing interlocking pavers over an existing hard surface (such as concrete or asphalt) requires a somewhat different approach than installing them on a softer surface (such as dirt or gravel).
You'll need a straight edge to line up your first row of pavers. If your subsurface is concrete, you can use the edge of the concrete as your straight edge. If your subsurface is soil or some other soft surface that has no definable edge, you can create an edge line by using string and wood stakes.
Step 2 – Place the Underlay
If you are planning to lay your pavers on soil, keep in mind that over time this surface is likely to change. Moisture or other natural factors will often raise or lower the ground surface beneath your pavers.
If you want this surface to remain more stable, you can create a more stable surface by first pouring a cement layer. You will place your interlocking pavers on top of the cement layer.
Or you can use sand or lime for this underlay. If you use a less stable material, such as lime or sand, you should use a tamper to create a more sound surface. Using a commercial tamper or a heavy, flat object such as a cinder block.
To make sure this underlay or subsurface is level, run a string along its top, with each end of the string secured to a stake driven into the ground. Then use a carpenter's level to ensure that your underlay or subsurface is level.
Step 3 - Prevent Weed Growth
If you lay your interlocking pavers on bare ground, you have to consider the issue of weeds. To prevent weed growth, you can lay a sheet of black plastic or landscaping fabric directly on the ground. Position your interlocking pavers on top of the plastic or fabric.
If you'd like to keep weeds or grass from invading your pavers, also install an edging along both edges of your paver surface.
Step 4 -Lay your First Outside Paver Edge
Begin laying your interlocking pavers along a pre-defined edge of your patio or pathway. Place each paver so that one straight edge of the paver is parallel with your patio or pathway edge. If individual pavers in this outside row have no straight edge, you'll need to use your paver saw to create an edge.
Step 5 – Lay the Rest of your Interlocking Pavers
With your outside edge of pavers in place, continue laying the remainder of your pavers. Aligning each piece so it fits into the grooves of adjoining pavers. In laying your last outside row of pavers, cut a straight edge on each outside edger.
