There are two methods used to attach AdvanTech panels to concrete slabs. Both methods require the preparation of the slab. Slab Preparation Cover the slab with minimum 4 mil (6 mil preferred) polyethylene sheeting. The polyethylene sheet should be glued to the slab with an adhesive that will bond to both concrete and plastic. All joints in the polyethylene sheeting should be lapped a minimum 4". These laps should also be glued to ensure an adequate moisture seal. The plastic should extend up sides of the walls a few inches. Once the AdvanTech sheathing is installed, the excess plastic can be trimmed flush.
Method 1 - Application direct to slab
• It is recommended that a square edge panel be used for this method.
• After preparing the slab as described above, place panels directly on polyethylene sheeting.
• Space panels 1/8" at edges and ends.
• Fasten panels with masonry nails, concrete fasteners or powder-actuated fasteners.
• Place fasteners 3/8" from panel edges.
• Space fasteners 6" o.c. at panel edges and 8" o.c. in the field.
Method 2 - Application to a joist system
• It is recommended that a T and G panel be used for this method.
• After preparing the slab as described above, install a joist system with 2x4's put on edge. Include rim joists to tie the framing together. The recommended joist spacing is 16" o.c.
• Lay panels on joist system with long dimension across joists. All panels should cover at least 3 joists.
• Space panels 1/8" at 4-foot ends. The T and G edge is self spacing.
• Use a minimum 8d ring-shank or spiral shank nail.
• Place fasteners 3/8" from panel edges.
• Space fasteners 6" o.c. at panel edges and 12" o.c. at intermediate supports.
