{"product_id":"adbri-300-series-single-core-concrete-block","title":"300 Series Single Core Concrete Block","description":"\u003cp\u003eWhen a 300mm wall has to carry serious reinforcement - a tall core-filled retaining wall, an engineered structural wall, or a big pier - this is the block. The single large core gives you a clear 290mm-deep cell that will take a proper cage of steel and let the concrete flow right through without a web in the way. Because Adbri's coding and published weights point to a A heavier unit than the Litec equivalent on Adbri's published weights - rather than a Litec lightweight, it also delivers around 238kg per square metre of wall, which is why it's often specified for boundary and party walls where sound insulation matters.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eKey Features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOne large 290mm-deep core - takes a full reinforcement cage, not just a bar\u003c\/li\u003e\n  \u003cli\u003eClosed ends hold the grout without formwork\u003c\/li\u003e\n  \u003cli\u003eNo intermediate web: concrete flows and consolidates cleanly\u003c\/li\u003e\n  \u003cli\u003e300mm wide - for tall retaining walls and heavily loaded structural walls\u003c\/li\u003e\n  \u003cli\u003eStandard-weight dense: around 238 kg\/m2 of wall, good acoustic mass\u003c\/li\u003e\n  \u003cli\u003ePairs with the 30.45 clean out block in the bottom course\u003c\/li\u003e\n  \u003cli\u003eFirst-quality units only, no seconds\u003c\/li\u003e\n  \u003cli\u003e60 per pallet, 53 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: 19kg each\u003c\/li\u003e\n  \u003cli\u003eCoverage: 12.5 blocks per m2\u003c\/li\u003e\n  \u003cli\u003ePallet quantity: 60 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":48188032319714,"sku":"ADB-B30925","price":11.5,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0648\/1261\/3858\/files\/300_Series_Single_Core.jpg?v=1787577784","url":"https:\/\/www.australianlandscapesupplies.com.au\/products\/adbri-300-series-single-core-concrete-block","provider":"Australian Landscape Supplies","version":"1.0","type":"link"}
