We frequently install thin pavers on top of base material when the project calls for it. For instance if we are remodeling an existing pool deck and the client wants to expand the deck area we will simply excavate the addition compact four inches of base material and install the thin pavers on top so that they are flush with the thin pavers we just installed over top of the existing pool deck. The reason we choose to use a thin paver in this example is to maintain color shade and variation consistency throughout the entire project. Thick and thin pavers never match exactly because they are manufactured at different times using different aggregates. The variation in color dye blending and moisture content of the sand and aggregates during the manufacturing process is what gives each batch of pavers its own distinct look.
Paver manufacturers are in business to produce as many pavers as quickly and as efficiently as they can. When they have to shut the system down to change out shape molds and adjust machinery to accommodate thin paver thickness they lose a lot of valuable production time. It can take hours to switch from one mold to the next. Additionally since thin pavers arent ordered as often the order quantities are frequently less and the manufacturer is forced to produce less pavers per mold and color. This inefficiency causes increased costs for the producers and they pass those costs on to their customers. So even though thin pavers use fewer raw materials to be produced they take up more time and time is money.
In fact you can typically notice a serious difference between any two paver areas in color shade or variation whether these areas were simply produced at different times or theres a difference in product thickness. This aesthetic sacrifice does not work for most clients and using a thin paver over prepared base for a purely pedestrian area is completely functional other than the aforementioned compaction difference when compared with a thick paver. If a client is simply interested in a new paver patio then thick pavers are the order of the day. Believe or not but thick pavers cost the same as thin pavers! Therefore there is not a difference in the project cost for the client when choosing to construct a brand new patio. Occasionally however a client simply likes the look be it shape or color of a thin paver vendor better than any of the options from the thick paver option. If this is the case we maintain that the aesthetics are the main priority of the project and we will utilize the thin pavers over prepared base.
Sealing pavers immediately after installation decreases chances of getting displaced or disfigured. The pavers set in sand move and adjust so in case a piece of pavers is chipped off in the process immediately replace it. So keeping a few extra pavers in stock is a good idea in case the particular design suddenly goes off the market. You dont want to ruin a perfectly symmetrical patio with one mismatched paver. If the pavers are laid on sand check them annually to see if the pieces have sunk. Brush in sand in the space in between them if necessary. The sand in the joints should be half as high as the level of the pavers. Sealing concrete in between prevents this problem.
