- Measure the area and excavate the project approximately 7-13 inches deep and 6-8 inches beyond the project's length and width.
- Depending on soil condition and content, you may need to use a geotextile (optional) to prevent base contamination.
- Next, install the base material, typically Type II road base in either green or grey. It is recommended that you install the base in one-inch intervals. For patio and walkways this should be approximately 4 inches of base, 6-8 inches for vehicular traffic. The 6-8 inches of base beyond the patio, walkway, or driveway will be the area needed for edging. This will give you a stable perimeter for your edge restraint or concrete boarder.
- Once you have installed and compacted the last layer of base material, it's time to add in the leveling sand. It is also called concrete sand, bedding sand, or mortar sand. This layer of material acts as a surface to make small adjustments to the pavers and help create the interlocking properties.
- After the leveling sand is installed, it's time to add the pavers. The starting point of the project will depend on the pattern, style, and shape of the paver. When you are installing a standard paver, it's best to start on the outside edge of the project and work out in a pyramid shape.
- When all the pavers are installed, add the finishing sand to the pavers. This will fill in the gaps between the pavers and leave some sand on top of the product, compacting the pavers. The sand will help protect the pavers from the compaction equipment and reduce scuffing and scratches. After the final compaction, sweep any remaining sand off the product and the project is complete.
Although the majority of the products we sell have color throughout the pavers, the color will soften over time. However, pavers are easy to restore to a like-new appearance using many sealer options.
It is the combination of the total installation, with the ratio between the thickness, length, and width of the paver, which makes them “interlocking”, not the shape. When installed with the ICPI (Interlocking Concrete Paver Institute) guidelines, the proper amount of base material, bedding sand, edge restraint, and finishing sand is used. This creates the interlocking property of the pavers, and gives the finished project a solid, yet flexible service.
- Pavers are installed in any climate. Snow can be plowed, blown or shoveled just like asphalt or concrete pavements. Remember the installer vibrated the paver surfaces flush to each other and the edges are chamfered. This means the pavers will not impede the removal of snow and ice as the overall surface is flush and free from catching an edge.
- Under-paver electric or liquid snow-melting systems can also be implemented to enhance snow removal while reducing slip hazards. Pavers that are darker in color can also use solar energy to naturally heat the surface augmenting snow melt and water vaporization.
- The density of concrete pavers (8,000 PSI) resists deterioration from freeze/thaw cycles and snow melt systems. Using snow melt salt or calcium chloride will not harm or pit the pavers. This trumps the performance of asphalt and ordinary, poured-in-place concrete.
If the pavers are installed with the proper amount of base, it is very uncommon to have weeds grow through the pavers. It is more common for the weed and grass seed to lodge into the joint of the pavers.
The white film is known as “efflorescence”. This is not a common occurrence, and is not permanent. It is a natural occurrence of the cement hydration process. Calcium oxide from the cement reacts with the water inside the hardscape product and forms calcium hydroxide. This seeps to the surface and reacts with the carbon dioxide in the air to form calcium carbonate, a white residue. When moisture on the surface evaporates, it becomes visible. It will wash or wear off over time and Western Turf and Hardscapes does carry cleaner for this issue.
Stains and oil will happen on most projects, but we carry several different types of cleaners for pavers. If the problem is too abundant, pavers are easily removable and can be replaced to maintain a seamless appearance.
