MORTAR SET ON CONCRETE
Fill joints with mortar or Polymeric Jointing Sand
MORTAR SET ON CONCRETE
SUITABLE APPLICATIONS: Interior applications over concrete. BENEFIT: Creates a very rigid surface.
18mm of latex mortar
DESIGN NOTES: For pavers or slabs with small joints, use polymeric sand in lieu of mortar between the units. Control joints in the reinforced concrete need to extend up through the mortar and pavers/slabs. INSTALLATION NOTES: When using mortar in the joints, be careful to prevent mortar from spilling over the joints, which stains pavers/slabs.
Reinforced Concrete (designed by others)
SAND SET ON CONCRETE PATIO OR ROOFDECK SUITABLE APPLICATIONS: Exterior patios or roofs over concrete decks. BENEFIT: Provides decorative surfacing over concrete that can be lifted/ replaced for maintenance or repairs. DESIGN NOTES: Concrete deck needs to be sloped away from building to drains as pavement surface follows same slope. Control joints in the reinforced concrete do not need to extend up through the bedding sand and pavers/slabs. Also, see Note 1 below. INSTALLATION NOTES: Geotextile required above protective board to prevent bedding sand loss. SAND SET ON CONCRETE ROOFTOP
Fill joints with Polymeric Jointing Sand 25mm of Bedding Sand
Minimum 2% slope to storm drain
Waterproof membrane Rigid insulation Protective Board Geotextile
PERMEABLE STONE SET ON CONCRETE PATIO OR ROOFDECK SUITABLE APPLICATIONS: Exterior patios or roofs over concrete decks where a flat pavement surface is preferred. BENEFIT: Same as previous, plus pavement surface can be at nominal drainage slope (drainage can occur in the aggregate base). PERMEABLE STONE SET ON CONCRETE ROOFTOP
Fill joints with ASTM 9 Clear Stone (or equivalent)
25mm of ASTM 9 Clear Stone (or equivalent)
ASTM 57 Clear stone (or equivalent), thickness varies
DESIGN NOTES: Concrete deck needs to be sloped away from building to drains; thickness of ASTM 57 varies as needed to provide flat pavement surface. Also, see Note 1 below. INSTALLATION NOTES: Size jointing material to accommodate joint width. ASTM 57 stone needs to be manufactured sharp stone (not round river rock) to prevent shifting.

Waterproof membrane
HYBRID SAND/PERMEABLE STONE SET ON CONCRETE PATIO OR ROOFDECK SUITABLE APPLICATIONS: Exterior patios or roofs over concrete decks. BENEFIT: Provides increased subsurface drainage (over sand set) to better handle moisture that infiltrated through the joints. DESIGN NOTES: A separation geotextile is required between the bedding sand and ASTM 57 stone. Also, see Note 1 below.

Wrap in geotextile to prevent aggregate loss
Note 1: On all concrete patio or roof deck applications, the roof drains need to have side slots that extend down to the waterproof membrane so that any moisture below the pavers can escape. Wrap the outside of the drain with geotextile to prevent bedding material loss.
