Paver Installation Process

Paver Installation Process

Step1 Demo concrete
During the demolition phase of your project our crew will break apart all of you existing hardscape. In driveways we will typically use heavy equipment. However, in walkways and patios we demolish by hand, using jackhammers, sledge hammers pickaxes, shovels, and wheelbarrows. We will then load up all of the concrete, asphalt or other hardscape materials in to a dump truck and haul it away.

Step 2 Remove soil, and organic material
Once the old hardscape has been removed, we will then remove the soil and organic materials. It is important to remove all organics and expansive soil from the project area because their existence can cause future shifting settling and buckling of the Pavingstones. Proper excavation and removal of soil will consist of 9.5" in vehicular areas and 7.5" in non-vehicular areas.

Step 3. Installation of utilities (drains, electrical, water lines, gas lines, etc.)
Once native soils and organics have been removed, we will then install needed utilities. This phase can vary greatly from one project to another. Some examples of utilities are: drain lines and drains, electrical conduit for lighting or outlets, water lines for irrigation, and gas lines for fire pits and barbecues. The installation of these utilities usually consists of trenching at the proper depth and placing the conduit or appropriate piping in the trench.

Step 4 Installation of outdoor elements (water features, walls, firepits, pillars bbqs)
If your project consists of any outdoor elements such as walls, fire pits , pillars, barbeques or any other type of feature, the construction of these elements will usually occur next.

Step 5 Re-compact soil
Now that your utilities are in place and the outdoor elements have been constructed your native soil will be re-compacted. During the demolition phase of the project the soil will usually become very loose. This compaction/vibration is the first of 4 during your installation process.

Step 6 Set grade lines
Now that the native soil has been sufficiently compacted, the grade lines will be set in place. This process is designed to eliminate ponding and puddling of water in the paved area. To achieve this, we will drive stakes in to the ground and tie masonry strings between them. This mason's line represents the final grad of the pavers. The crew will then measure the distance between the final grade and the sub soil.

Step 7 Install Geo tex fabric
Many areas have expansive soil. During periods of heavy precipitation, expansive soil becomes saturated. Often times this native clay will actually migrate up into the road base and cause movement and settling of the pavingstones. In such areas, a barrier will need to be installed between the native soil and the road base (described in the next section). Geo tex fabric is a woven pvc mesh that provides this barrier.

Step 8 Install class 2 road base
Over the compacted soil or geo tex fabric, class 2 road base will be installed. In vehicular areas 6" of base will be installed. In non-vehicular areas 4" of base will be installed. The nature of class 2 road base is similar to gravel. However upon closer inspection it is evident that the material is varied in size, from 3/4" rock to fine dust. The nature of this material allows a very dense compaction rate with minimal air pockets between the larger aggregates.

Step 9 compact road base.
Now that the class 2 road base is in place it will need to be compacted. This is the 2nd of 4 compactions. This compaction will achieve a 95% compaction rate of the base material.

Step 10 Screed bedding sand
After the base has been sufficiently compacted a 1" layer of sand will be applied over the base. To achieve exactly 1" of sand, we will lay out parallel pipes over the base material. These pipes are 1" in diameter. These pipes will then be set to grade by comparing their height with the mason's lines representing final grade. Sharp angled bedding sand will then be shoveled over, between, and surrounding these pipes. A 2x4 piece of wood will then be run over these pipes to screed the sand. This creates a perfect and pristine layer of bedding sand on which to hand lay the paving stones.

Step 11 Lay pavingstones in selected pattern
The pavers will then be laid in the selected pattern, stone by stone. Usually the pattern will be started in a central location and radiate outward towards the perimeter of the project. Once the pattern reaches the perimeter, the borders will be installed.

Step 12 Mark and cut stones for preparation of border.
In many projects the outside edges are arranged in soft sweeping curves and turns. For this type of project, PVC piping will be used as a guide to scribe "cut lines". PVC piping is used because it bends in uniform arcs. The stones will then be cut along the "cut lines" and the waste will be discarded. The useable piece of the paver will be placed back in to the pattern in its original location. The result of this process is a perfect line of cut pavers in preparation for the border stones.

Step 13 Border against fixed structures
In many areas of a project the pavers will abut a fixed structure, like the foundation of a garage or a concrete sidewalk. In these areas a straight line will be scribed on the pavers which is parallel to the fixed structure. This will create a gap between the fixed concrete structure and the newly cut pavers. This gap equals the exact length of the stones used for the borders. These border stones will then be wedged into place between the fixed structure and the newly cut pavers. A fixed structure will act as a solid lateral edge restraint for the pavers and prevent any movement of the pavers.

Step 14 Install concrete bond beams against softscape areas
In many areas of the project there will be no fixed structures to pave against. In these areas a concrete footing or "concrete bond beam" will be installed. At the cut edges of the stones a trench will be dug. This trench will be filled with concrete. The border stones will then be wet set in the fresh concrete footing tightly against the newly cut pavers. Once the concrete bond beam cures the affixed border pavers will become an integral part of the footing. This locks the project in place from the perimeter.

Step 15 Compact and vibrate over stones
Now that the paving stones are locked in place at the perimeter, the project will be re- compacted. This is the third of four compactions. This will have the effect of making all of the stones level and even with one another. It will also draw sand up between the stones from underneath.

Step 16 Sweep in more bedding sand
Dry sharp angled bedding sand will then be swept over the paved area in all directions. A 1/8" layer of sand will cover the pavestones.

Step 17 Compact and vibrate over layer of sand
Using a plate compactor vibrating machine, the paving stones will then be re-compacted over the layer of sand. This final compacting will vibrate and wedge the sand in between the pave stones. Once completed the joints between the stones will be filled from bottom to top with sand.

Step 18 Sweep and hose off paved area
The extra sand will then be swept from the surface and discarded. The pavers will then be hosed and cleaned.

Step 19 Apply sealer
A Joint sand stabilizer will be used to seal the area. This joint sand stabilizer is an acrylic that saturates the joint sand. Upon curing the sand will be bound together. The sealing process is necessary to prevent seed germination and weed growth between the pavers.
