Belgard porcelain pavers can also be installed as a permeable system. Replace sand with a 2 inch thick bedding course or a 3/8 inch crushed open grade aggregate. Replace 3/4 minus base with a 3/4 crushed open grade aggregate.

Compacted subgrade, prepare acording to recommendations in geotechnical report Soil Equal to base thickness Subbase extends beyond curb to provide working platform for installation 1” Bedding layer, conforms to ASTM C33 with < 1% passing 0.80 mm. 2x #4 rebar Compacted road base 3/4” minus road base material. Base thickness is determined by soil and climatic conditions. Base layer, Min. 3” ASTM No. 57 stone In order to ensure proper drainage, the installer must adjust the base thickness and subgrade composition to account for local climatic and geological conditions. Drainage Site specific conditions will determinethe location and quantity of linear drainage.
