AAC Block Walls
Ensuring structural integrity
Cut channels as small as possible. Do not use impact
tools such as hammers or any other cutting tool that will damage the adjacent wall.
Reduce the number of channels by taking services
behind wall where possible.
Do not route channels in floor or ceiling panels. A
perpendicular hole may be cored through the reinforced
panel if less than 1/4 panel width.
1. Vertical routing
Vertical channels may be cut by router or saw to a width not to exceed 6" unless otherwise restricted by drawings or specifications. Do not be cut channels directly under point loads.
2. Horizontal routing
Cut horizontal channel(s) no deeper than 1/3 of the wall thickness and no less than 24" from the top of a bearing wall unless otherwise restricted by drawings or specifications. Do not cut back-to-back channels. Offset channels at least 12" when routing on both sides of wall. Make access holes in the wall on the opposite side of the channel where necessary.
Step 1
- Mark channelUsing a straightedge, mark both
sides of the groove with a pencil.
Step 2
- Cut along markingsMethod 1: Cut channel with channel router (AAC router).
Method 2: Set a blade on a circular saw or concrete cutter to the necessary channel depth. If using a circular saw make cuts for each side of the channel and an additional cut in the middle.
Do not cut the channel deeper than necessary.
