13 Permeable Installation Guide : VAST Support Center Caulking Gun Adhesive (click for recommendations) Project Design, Pattern and Color Choice NOTE: AZEK VAST Pavers allow for any shape installation, including straight and curved edges. Calculate Square-Footage: Measure the dimensions of the paver area and calculate the total square footage. Be sure to add extra to the measured square footage to allow for scrap and to have a few extras on hand in case of future damage. Calculate Amount of VAST Product Required: A unit of AZEK VAST Pavers includes 8 pavers and a 16.0 x 16.0 grid. The unit covers 1.78 square feet. To calculate how many units are needed, divide the total square footage of the project by Here is a table for reference: Choose Pattern : AZEK VAST pavers can be installed in a multitude of different patterns and combinations. Designs can include small and large repeating patterns. Some example patterns are provided below: Herringbone Basketweave Running Bond IMPORTANT: At least one paver must connect two grids in each direction. The herringbone pattern does this without needing to specially orientate the grids. Here is how the grids must be orientated to assure overlap in all directions for other patterns: Herringbone: This is the most popular and easiest to install pattern. Pavers will interlock grids in both directions. Lay the installation grids as illustrated below. Start laying pavers at the starting corner. 1:31:32 PM]

14 Permeable Installation Guide : VAST Support Center Basketweave: This is the simplest installation method for a Basketweave pattern, but it will require extra installation grids. The starting paver must be laid 4 down and 4 over from the top left corner of the grid. This will shift the pattern over and assure at least one paver will connect two grids in both directions. The leftover grid can either be trimmed off, or a 4 border can used to fill in the extra space. Running Bond: This pattern will require the staggering of grids to assure the pavers will connect them in both directions. The starting paver can be laid in the top left corner, but the next column of grids must be staggered halfway down the starting row. Every other column will need one half grid at the top. Each half of the cut grid can be used. Decide on Border / Soldier Course: The AZEK VAST Paver system allows for several border and soldier course options. These can either be straight or curved. The accessory pavers can help limit the cutting and give a finished look to the project. For more information see Install Borders and Accessory Pavers below. 1:31:32 PM]

15 Permeable Installation Guide : VAST Support Center Pick Colors: AZEK VAST Pavers come in five brilliant colors that can be used by themselves or combined to create unique blends. To help select the colors for your project, check out the following resources: Site Planning and Marking IMPORTANT: Locate Utilities. Prior to beginning the installation, ensure all underground utilities (e.g. electrical lines, phone lines, water lines) have been properly located and identified. Mark Project Area: Once the project layout has been determined, mark or spray paint the overall outline, approximately twelve inches wider than the planned installation area. This will provide the additional excavation area needed for installing edging. Any pavers that abut structures or other paved areas will not require installed edging and therefore do not require the additional twelve inches of excavation. Base Material Design IMPORTANT: The preparation of the site and base material is critical to a long lasting, flat and premium looking installation. Also, a properly prepared site will reduce installation time. Please contact a landscape professional if required. Subgrade: The subgrade is the existing soil or surface that the installation will be built upon. Subgrades that are primarily clay or silt are the weakest subgrades and typically require additional base material. Geotextile: Geotextile material can be used to help prevent poor subgrade conditions from mixing with the base material. Heavy foot or vehicular traffic conditions are also good conditions for using geotextiles. The geotextile will be placed between the subgrade and the base material. Permeable Base Material: IMPORTANT: A civil engineer, landscape professional, or local municipality, is recommended to design the appropriate permeable base. Each permeable application is different, and there are multiple considerations that must be taken into account (e.g. amount of rainwater, runoff water from hills and downspouts, soil type, the infiltration rate of the pavers, etc.). A permeable base is typically comprised of multiple layers of different sized fractured-face stones. The base material should be an open-graded aggregate, free from sands and other small particles. Please refer to local requirements and specifications, or visit ICPI.org for more information. Here is a generic permeable base found on the ICPI website. The base material needs to be compacted every 2 as it is spread out. This will reduce any chance of the base material settling over time making the installation uneven. Additional resources for base design can be found at: Slope: ICPI Project Drawings It is very important to slope the sub base (ground beneath the permeable base material) away from any building structures or foundations. The typical slope is approximately 1 over 6 feet. Bedding Layer: The top layer of the permeable base that the AZEK VAST Permeable Pavers will sit on is comprised of 1.5 to 2 inches of a 3/8- clean, fractured-face rock. This will create a workable and permeable surface for the pavers to install upon. Use a chip rock free from smaller particles (3/8- chip rock or No. 8 stone). Compact the bedding layer with a hand tamper or vibratory plate compactor. Excavation: To install the necessary base material, the existing ground material must be taken out. To calculate how deep to excavate, add up these layers: Excavation Depth = Permeable Base Material Thickness (Pavers) - 1/4" Once the excavation depth is known: Excavate site to the appropriate depth. Slope the sub base to approximately 1 over 6 feet away from any structures or foundations. A geotextile is optional between the sub base and permeable base material. 1:31:32 PM]

16 Permeable Installation Guide : VAST Support Center The subtraction of 1/4" leaves room the sinking that occurs during the final compaction. Level and compact the subgrade to a 95% proctor density (ASTM D 698) If needed, always have the compaction formally tested to ensure it meets the required standards. Install Base Material and Sand Bed Install and Compact Base: Add base material 2 inches at a time. Compact each layer completely with a plate compactor or hand tamper. Compact to 95% proctor density (ASTM D 698). Be sure to compact all edges and corners thoroughly as these are at the most risk to degradation. Limit any undulations to under 1/4" to limit any dips or humps in the final installation. Install, Compact, and Level Bedding Layer: Add a 1.5 to 2 inch layer of chip rock (3/8- clean, fractured-face rock or No.8 stone) Level the bedding layer appropriately and tamp with a hand tamper or vibratory plate compactor. Add chip rock to areas that are uneven and smooth them out. Installing Grids and Pavers Pick a Starting Point : Picking the right starting point will make your installation quicker and easier: Start off the longest straight edge to reduce the amount of cutting, or off of a building structure. Starting in a corner and working out in both directions is typically preferred. Account for Expansion: AZEK VAST Pavers will expand and contract with temperature change (similar to other composite materials). To accommodate for expansion, the following measures must be taken: IMPORTANT: Always install in temperatures greater than 40 F. For AZEK VAST Permeable Pavers: Leave a 1 gap around all damageable protrusions (e.g. light posts, vent pipes). If the pavers are installed up against asphalt, a 4 concrete ribbon the depth of the base is recommended between the two. Expansion of the AZEK VAST Pavers may push the asphalt causing it to buckle. Installing Installation Grids: REMINDER: Installation grids must be orientated to allow the pattern of pavers to interlock grids in both directions. Please refer back to Choose Pattern for more information. Begin laying grids from the starting point of your choice, on top of the already installed bedding sand. Lay out approximately 10 grids to make room to install pavers. To increase installation speed, it is recommended to purchase 10 extra installation grids to get started. As pavers are brought over and installed, the grids from those pavers will continuously be laid out across the install. Grids can be cut to fit with the same cutting tools used for the pavers (e.g. mitre saw or jigsaw). If the ending grid is less than 4, cut off 4 or 8 of the grid before it, so the ending grids can be longer and will connect into the install with overlapping pavers (e.g. instead of a 16 grid then a 3 grid, create an 8 grid and an 11 grid). Lay Down AZEK VAST Pavers: 1:31:32 PM]

17 Permeable Installation Guide : VAST Support Center Bring stacks of pavers on the grids over to the starting point. Empty pavers off of grid and lay them in the desired pattern in the grids. Take empty grids and lay them out in the continued orientation needed for your pattern. Continue laying pavers until all full pavers are installed. Cutting Grids and Pavers IMPORTANT: Using the recommended blades will save both time and equipment. Please refer back to the top for recommendations based on cutting equipment. Cut a Single Paver: Use the recommended cutting equipment (top of installation instructions). Cut pavers individually using a spare grid to hold it in place. For miter saws, short quick swipes with the blade works best. Keep the blade speed up and avoid binding. Cut pavers may be adhered to the grid for more security. Cutting the Grid: Use the recommended cutting equipment (top of the installation instructions). For mitre saws, one or two swipes of the blade works best, keep the blade speed up and avoid binding. IMPORTANT: ALWAYS WEAR SAFETY GLASSES, GLOVES, AND EAR PLUGS WHEN TRIMMING PAVERS OR GRIDS. Obey all safety and operational instructions that came with your cutting equipment. Install Borders and Accessory Pavers If the project requires curved or straight borders the accessory pavers can eliminate much of the cutting. These include legless pavers and wedge pavers. Draw the shape of the desired border onto the pavers that will need to be cut. Laying the accessory pavers on top of the installed pavers in the desired design and tracing the interior edge is the easiest way to do this. A string line may also be used. Cut along the line in place with a jigsaw (use a 5-6 tpi blade). DO NOT cut through the grid. Place the legless and/or wedge pavers on top of the installation grids to create the border. Use an adhesive between the accessory pavers and the grid. Install Edging Edge Restraints: AZEK VAST Pavers require the use of an edge restraint around the perimeter. Edge restraints help keep the installation from moving, and perimeter pavers from tipping off the grid. The edging is generally staked down using 10 stakes, one every 6 to 12 inches. Plastic, aluminum, or concrete edging will work. Edge restraints can be installed next to, or on top of, AZEK VAST Installation Grids. For areas that will eventually be bordered by sod, or that have a curved perimeter, some may prefer to install edging over the top of the installation grids. If this is done, drill holes in the grid where the stakes will go. IMPORTANT: When installed up against asphalt, a 4 wide ribbon of concrete the depth of the base material is recommended. Expansion of the AZEK VAST Paver system may push the asphalt causing it to buckle. Tamping Pavers and Joint Fill The final steps to finish up the installation are tamping and sweeping chip rock between the pavers. This will even out small undulations and lock the pavers into place. Tamp (Compact) Pavers: Prior to sweeping chip rock between the pavers, use a vibratory plate compactor or a hand tamper to work the pavers into the bedding layer. This will typically cause the pavers to sink approximately 1/4" into the bedding layer and will even out any small undulations. 1:31:32 PM]

18 Permeable Installation Guide : VAST Support Center A vibratory plate compactor will take 1 to 2 passes in both directions. A hand tamper will require several strikes in each location. Move around as you strike the pavers and make several passes. The high undulated areas can be tamped down more to even the surface. IMPORTANT: Review the surface after tamping for any imperfections. If any are found, lift up the pavers and grid and either add or remove chip rock to make it level. Re-tamp the pavers after the imperfections have been removed. Sweep in Joint Fill: The same chip rock used for the bedding layer can be used for the joint fill. This is a 3/8- clean, fractured-face stone. The standard specification for permeable joint fill is ASTM No. 8 stone. Start by spreading the chip rock out across the pavers with a shovel. Using a broom spread the chip rock across the joints, sweeping in all directions. When the joints appear to be filled to the desired level, sweep the installation clean of any remaining chip rock or dust. The pavers will return to their original color once the pavers have been cleaned by rain. An additional sweeping may be necessary after rain or settling of the joint sand occurs. IMPORTANT: Do not use sand, or polymeric sand with the AZEK VAST Permeable Paver system, and do not tamp the pavers after the chip rock has been placed on the pavers. Maintenance Most stains, bird droppings, etc. can be cleaned using a garden hose. Tougher, embedded debris can be cleaned using a high-pressure sprayer and a mild detergent (similar to that used for cleaning your car). NOTE: Be careful when using a high-pressure sprayer so as to not "etch" the paver surface or cause the pavers to dislodge. For further maintenance information please visit our Support Center at support.vastpavers.com. The techniques shown above should be used for best results. Results may vary as expansion and contraction could still occur, and drainage systems are unique to each flat roof. VAST Enterprises, LLC claims no liability or responsibility for the improper installation of this product. Since all installations are unique, it is the sole responsibility of the installer to determine specific requirements in regard to each flat roof application. VAST Enterprises, LLC recommends that all designs be reviewed by a licensed architect, engineer or local building official before installation.
