A method for concrete horizontal superimposed row burial niches building, comprising an expanded plastic extractable block form core (1, 2) with hooking means (8), covered with a flexible covering plastic bag (12) which after the concrete grouting is hardened, remains glued in the concrete layer allowing the easy extraction of the extractable block form core (1, 2) and a new covering bag (12) can be replaced for covering the block form core in order to allow the re-utilization of the form core in another concrete grouting, and so on for further concrete groutings. |
