One of the most widely used methods for the installation of pavers is hand installation of each paver. It is best to install a single row of pavers along one of the true straight lines that you have pulled or above the bedding sand. This will give you a straight and true line off which to work. Once this row is established, you can continue to work outward into the field with the rest of the pavers. Always make sure to periodically check your joint lines to make sure they are true and straight. If not, adjustments to the pavers can be made as you continue installing. Pavers should be installed hand tight. The best method is to place a paver against another one and let it slide down into the bedding sand. Do not kick or tap the pavers into place as this can throw your lines out of true straightness.Our website provides info on patio pavers
When installing pavers on a steep grade, they should be installed at the base of the grade going uphill. This will prevent the pavers from creeping as they are being laid. On large commercial and industrial applications, hand laying pavers would not be cost effective due to the labor intensity. The best way for installing pavers on large projects is to install them mechanically. The use of a mechanical laying machine can install approximately 6000 – 7000 sq ft a day. There are a couple items a contractor should consider before installing pavers mechanically:
1.) Mechanical installers are only capable of installing pavers in certain patterns.
2.) The contractor must make sure that the manufacturer is capable of manufacturing and bundling pavers in the desired pattern on the pallets for easy mechanical installation.
3.) Contractors may encounter a color blending situation coming off the bundles of pavers. Poor color blending could result in a patchy looking installation. Most manufacturers are consistent with color blending on each bundle of pavers, but it is the contractor’s responsibility to ensure proper blending in the field.
Contractors typically have two ways of cutting pavers. Pavers are cut either by 1). A double bladed guillotine or by 2). A gas powered cut off saw or brick saw which is equipped with a diamond blade. The diamond blade cut-off saw or brick saw will provide a much cleaner and more accurate cut. Most brick saws will have a hose attachment on them which will allow the operator to cut the pavers wet. When cutting pavers wet, it will help minimize dust and will prolong the diamond blades life as well. The operator of the brick saw should always cut the pavers away from the surface of the paver field when cutting wet, due to the fact that the pavers will create a slurry that will stain the paver surface. Pavers that are cut should not fit tight, sufficient spacing should be available for jointing sand. The brick saw operator should always wear the proper protection that is needed for operating a saw, such as eye, ear, respiratory and hand protection ).
Edge restraints play a major role in the overall success of an interlocking pavement installation. Edging restraints eliminate lateral movement of the pavers and hold the pavers tightly together. Especially at the outer perimeter of the paver application, without an edging restraint, your project is guaranteed to fail over time.
There are several different edging restraints from which contractors can choose. Typically manufactured edge restraints are the most commonly used by contractors. Manufactured edging restraints can range from, plastic edging, steel and aluminum, timbers or precast concrete and stone. An edging type that is used primarily in commercial and industrial applications is poured-in-place concrete curbs. This edging restraint is typically installed by other contractors.
