BUILDING WITH BYBLOCK

ByBlock Dimensions

• 15.5" width x 7.75" depth x 8" height
• Thru holes are spaced 7.75" on centers, and 3-7/8" from ByBlock edges
• Corners require three post-tension rods and every 15.5" in the field as seen in the following steps.

Step 2

ByBlock assemble the same as any other brick/ block building material - in alternating courses.

Using Standard ByBlock: BBK-011, begin stacking in the corner (if applicable) and continue to stack ByBlock toward the ends of the wall assembly in both directions. To expedite the stacking process, pre-cut half ByBlocks before you begin stacking your wall.

Step 3

There are no adhesives or fillers required when building with ByBlock. Feel free to stack as quickly as you like, so long as you are practicing safe handling methods.

Continue to stack Standard ByBlock until there is one course remaining to be placed. The top course will be placed using Flat ByBlock.

Step 4

Flat ByBlock: BBK-012 are the same in size and dimension as Standard ByBlock. However, they lack the ‘pin’ located on the top. This flat surface ensures that post-tension pressure is evenly applied across the top of the wall assembly.

Complete the ByBlock stacking with Flat ByBlock on the top course.

Step 5

After you have completed stacking the ByBlock, place your pre-drilled top plate over the threaded rods; firmly resting on the Flat ByBlock surface.

When cutting and pre-drilling your top plate, do not measure the rod position at the top of your wall assembly. The top plate hole positions should be identical to the rod position in the concrete base. Duplicating these measurements will maintain proper vertical alignment of the rods.

Step 6

Place washer and nut onto each threaded rod and position onto top plate. Using a through-bolt socket, begin applying tension evenly across the top plate. using a through-bolt socket. Using a through-bolt socket will enable you to continue tensioning the nut without having to cut the threaded rod as you make progress.

After the tension is consistent, cut back the excess threaded rod and using a standard torque wrench, ensure a minimum of 45 foot-pounds of tension has been applied to each rod. Using a level and/or tape measure, check the overall height is consistent from footer to top plate. Using any readily available cutting tool, remove any remaining threaded rod to a level just below the top-most surface of the top plate.

In order to achieve a flat top plate after post-tensioning, drill a larger diameter hole on top just enough to recess your washer and nut.
