Rain Test on Rammed earth walls.

It rained 8 cm (3inches) last night.  the first big rain on some rammed earth garden walls.

This wall has no overhang, but a cap of rammed earth with 8% lime and lime wash.  Although the wall got wet it is still hard
 Wall with a brick over hang, painted bricks.  there was seepage but wall is hard.

Mayge this one had better coat on top of overhanging bricks.

wall sits on lime stabilizied rammed earth foundation.  plastic on top of foundation.  no or little water sucked up into wall.


small room along wall with lime stabilizied rammed earth plaster.  some seepage

Another wall.  the dark is seepage.  Wall is hard.  lime stabilizied rammed earth in upper section.
 another view  .  lime/clay wash
 lime washed wall

    Walls are holding up pretty good. You might be lucky. I imagine rammed earth walls where the soil has a lot of smectite clay would self-destruct in climates where there is a defined wet and dry season. In that case I wonder if cob might hold up better. Straw availability might be limiting in your case(?).

    1. I think RE actually holds up better than cob. it is har der, so water is slower to penetrate. although they are similar. I can take a hose to my walls, and if was made right there is no damage
