How to Add Strength and Stability to Posts or Pillars

When building a taller landscape project like a concrete post with the AB Courtyard Collection by Allan Block, added stability may be necessary. Watch detailed information on stacking the blocks, adding a sonotube or changing the foundation if poor soils exist.

Block columns can be used to create gates into your back yard. You can also make your block posts taller in your Courtyard fence and add wrought iron panels between posts. Use taller post in your next landscape project to elevate your design into something wonderful.

You can find complete installation instructions, a local store near you, as well as design ideas and easy to use estimating tools at our website:

    How to Add Strength and Stability to Posts or Pillars – you should glue every course together with the same adhesive you use to glue the cap on…come on.  That video missed the mark on that one.

    Would be more stable and have greater longevity if you pour concrete footing with rebar and lay the stone using mortar.

    Mike, these are built in all climates, in fact the video itself was filmed in Minnesota, where they are known for some harsh winters. However if you are concerned about frost-heave, I would recommend digging your footing down past the frost line.
