How To Level Concrete Block

To build a good looking concrete block wall it is critical to get the first course perfectly level. This can be challenging when the foundation wall is not level. Wobble Wedge tapered installation shims makes this job easy and fast. Here's how:

Step by Step:

  1. Select hard Wobble Wedges of the appropriate size (see 4 Interlocking Sizes).
  2. Set a level string line on both sides of the block as a guide
  3. Press or lightly tap a Wobble Wedge under both sides of the blocks as needed to bring them squarely up to the guide line.

If needed, Wobble Wedges can be securely stacked to fill the larger gaps.

Wobble Wedges can be used in all block courses to set and maintain and even joint width.
