Follow the detail drawing. • The required edge restraint system for this installation has a vertical height of 2½ inches as shown in the drawing. Follow the edge restraint manufacturer’s recommendations for the use of their product in permeable applications regarding geogrid usage and placement to maintain the performance of their edging. • Ensure that pavement is constructed with a 2 percent slope and that it is pitched away from any building. • Ensure the 4 mm spacers are installed between all pavers. • The open-graded aggregate should be clean and free from foreign matter, manufactured from crushed rock and conform to ASTM C33 size No. 57. Do not use recycled aggregates or rounded river gravel. • Additional Drainage: If the project has fine-grained soils, silts or clays, and contributing water sources such as downspouts or groundwater, it is important to install a perforated pipe underdrain to prevent saturation of the subgrade. Make sure underdrain has an acceptable discharge location. • When installing porcelain planks (12 x 48 & 8 x 48), always lay the pattern of 1/3's. These should not be placed next to each other at 50 percent. • Roller Compactor recommended for all compaction with Porcelain products PEDESTRIAN FOOT TRAFFIC ONLY OPEN GRADED AGGREGATE INSTALLATION EDGE RESTRAINT SYSTEM W/ GEOGRID STABILIZATION INSTALLATION NOTES: Follow the detail drawing. The required edge restraint system for this installation has a vertical height of 2 1/2” inches as shown in the drawing. Follow the edge restraint manufacturer’s recommendations for the use of their product in permeable applications regarding goegrid usage and placement to maintain the performance of their edging. Ensure that pavement is constructed with a 2% slope and that it is pitched away from any building. PLANKS When installing porcelain planks (12x48 & 8x48), always lay the patterns of 1/3’s. These shoud not be placed next to each other at 50%. Important: For a professional and chip free cut, Belgard/Mirage Porcelain pavers should only be cut with a tile saw equipped with a wet cut porcelain blade. Caution: Never compact Belgard Porcelain pavers with a plate compactor. Never install Belgard Porcelain pavers without the required 4mm disc spacers between all units. 4mm disc spacer (with break off tabs for different patters) 20mm (0.7874”) Porcelain Slab 2” pre-compacted 3/8” open graded aggregate Geogrid to stabilize the restrain system 2.5” Aluminum/plastic edge restraint with Geogrid (install per edge restraint manufacturers details) Belgard/Mirage 20mm (3/4” nominal) pavers Use 4mm disc spacers between all pavers and fill joints with Storm TM jointing compound by TechniSeal Note: Pre-compact the open graded bedding course into the base course. Smooth and level laying surface. Drainage Site specific conditions will determine the need of underground drain pipesto prevent sub-base saturation. Compacted subgrade, prepare acording to recommendations in geotechnical report Permeable Geotextile Fabric (Mirafi 140N or equal) Geogrid installed to stabilize edge restraint. Width of geogrid shall conform to edge restraint manufactures requirements. Soil Equal to base thickness 2” Bedding layer, ASTM No. 8 stone. 6” min. base course, ASTM No. 57 stone. Perforated drain pipes located at the lowest spots to discharge excess water determined by others* Perforated pipe needs to be surrounded by 3” min. ASTM No.57 The use of a Porcelain Roller Compactor is MANDATORY! In order to ensure proper drainage, the installer must adjust the base thickness and subgrade composition to account for local climatic and geological conditions.
