Hi all
building a 1m high retaining wall with perforated draining in the back with geo textile fabric against the soil before putting clean gravel down.
do I need to add a Dpm against the rear wall face? It’s been constructed in 100mm concrete block laid flat (215mm) with an additional skin of reclaimed bricks
thanks in advance
