I think I did the question wrong, is it the same to revoke the layer (common bricks glued with the mixture you say) before continuing to lift the wall ???
sorry. The one that I misunderstood is me. You want to make a horizontal layer, I thought it was vertical. It is indeed as you say. The foundation bricks are made, encased or formwork about 3 to 5 cm, Ø 8 mm iron is placed and concrete is placed with water repellent. Once dry, allowing 3 to 4 days to pass, you apply asphalt paint and a piece of plastic film (they are sold at hardware stores) and then start with the wall.
