Dry Stack Masonary Units, without Surface Bonding Cement(!)?
A quick summary of my project…
- 8mx7m log cabin
- Stepped foundations that range from 80cm to 100cm
- CMU units designed for Dry Stacking 24cmx500cmx25cm
- 2 * 12mm vertical rebar for each cell in vertical wall that will be 2m high from foundation footing
- 2 * 12mm vertical rebar for every other cell in vertical wall that will be 1m high from foundation footing
I am in Poland after moving from UK, it appears they are familiar with the technique of dry stacking CMU units and filling the holes with rebar and cement, the CMU units I have purchased appears to be good with a high-quality factory finish that interlocks each block.
Now, I requested Surface Bonding Cement but none of the suppliers I have spoken to know what this is, I explained the technique and have been told by everyone I question that in Poland they just add rebar and fill the voids of the CMU with cement.
My only option appears to be making my own Surface Bonding Cement, what I am not that keen on doing as I wanted to dry stack to save time and keep things as simple as possible.
I have researched as much as possible and cannot find anything in English that details using dry stacking technique with rebar and cement in all voids and not using Surface Bonding Cement.
I’m interested in feedback regarding this, I would think that the CMU units with rebar and cement in each void would be very strong and just a simple render over the block work to fill in any gaps and provide water proofing would suffice?
