{"product_id":"adbri-litec-300-series-h-block","title":"Litec 300 Series H Block","description":"\u003cp\u003eThe 300 Series H Block is the workhorse for the bottom of a tall, core-filled retaining wall. Because both ends are open, the bricklayer lowers it sideways over the starter bars projecting from the footing rather than lifting each block over the top of the steel - much faster and far safer. The open ends also leave a clear channel for concrete to flow the length of the wall, so the grout fills properly instead of bridging. Most engineered walls run 300 series H blocks for the first few courses, then step down to 200 series higher up where the loads ease.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOpen both ends - laid around vertical starter bars, not threaded over them\u003c\/li\u003e\n  \u003cli\u003eContinuous unobstructed grout channel: better concrete flow, fewer voids\u003c\/li\u003e\n  \u003cli\u003eSuperior to closed-end blocks wherever there's vertical reinforcement\u003c\/li\u003e\n  \u003cli\u003eStandard for the lower courses of high retaining walls before switching to 200 series above\u003c\/li\u003e\n  \u003cli\u003eLitec lightweight - 15.80kg vs a dense 300 series unit\u003c\/li\u003e\n  \u003cli\u003eAdbri quotes f'uc of 15 MPa or greater for this shape\u003c\/li\u003e\n  \u003cli\u003e72 per pallet, 63 per tonne\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eMaterial: Concrete\u003c\/li\u003e\n  \u003cli\u003eDimensions: 390 x 290 x 190mm\u003c\/li\u003e\n  \u003cli\u003eWeight: 15.8kg each\u003c\/li\u003e\n  \u003cli\u003eCoverage: 12.5 blocks per m2\u003c\/li\u003e\n  \u003cli\u003ePallet quantity: 72 units\u003c\/li\u003e\n  \u003cli\u003eManufactured to AS\/NZS 4455.1\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Adbri Masonry","offers":[{"title":"Default Title","offer_id":48188032123106,"sku":"ADB-30.48","price":8.2,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/1261\/3858\/files\/Litec_300_Series_H_Block.jpg?v=1787219729","url":"https:\/\/www.australianlandscapesupplies.com.au\/products\/adbri-litec-300-series-h-block","provider":"Australian Landscape Supplies","version":"1.0","type":"link"}
