Stacked dry around the reinforcement cage and filled with concrete, it forms a semi-monolithic reinforced column — the blocks are the permanent shell, the poured core carries the load.\u003c\/p\u003e\u003cp\u003eUsed for fence posts, gate piers, porch columns and the intermediate supports of a boundary wall — typically together with the wall formwork blocks, which run between the columns. The block surface keys well to render, so a finished column can be plastered or clad without further preparation.\u003c\/p\u003e\n\u003ch2\u003e\u003cstrong\u003eKey benefits\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eForms a reinforced concrete column without timber formwork\u003c\/li\u003e\n  \u003cli\u003eClosed square cavity for the reinforcement cage\u003c\/li\u003e\n  \u003cli\u003eLaid dry, without mortar\u003c\/li\u003e\n  \u003cli\u003eTwo sizes: 25 and 30 cm\u003c\/li\u003e\n  \u003cli\u003e4.3 pieces per linear metre of column\u003c\/li\u003e\n  \u003cli\u003eSurface keys well to render and cladding\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eTechnical specifications\u003c\/strong\u003e\u003c\/h2\u003e\n\n\u003cul\u003e\n  \u003cli\u003eProduct type: concrete column formwork block\u003c\/li\u003e\n  \u003cli\u003eBrand: Leier\u003c\/li\u003e\n  \u003cli\u003eMaterial: vibro-pressed concrete\u003c\/li\u003e\n  \u003cli\u003eSizes (L x W x H): 250 x 250 x 230 mm, 300 x 300 x 230 mm\u003c\/li\u003e\n  \u003cli\u003eWeight per piece: 12.8 kg (25 cm), 16.2 kg (30 cm)\u003c\/li\u003e\n  \u003cli\u003eCoverage: 4.3 pieces per linear metre\u003c\/li\u003e\n  \u003cli\u003ePieces per pallet: 80 (25 cm), 60 (30 cm)\u003c\/li\u003e\n  \u003cli\u003eLaying: dry stacked, filled with concrete\u003c\/li\u003e\n  \u003cli\u003eUse: fence posts, gate piers, porch columns\u003c\/li\u003e\n  \u003cli\u003eSold by: piece\u003c\/li\u003e\n  \u003cli\u003eDelivery: made to order, subject to supplier stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003e\u003cstrong\u003eRecommendation\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cp\u003eSet the reinforcement cage into the footing before stacking the first block, and check it is plumb — a column cage that leans cannot be corrected once the blocks are on.
