We both manufacture and on sell 1 Tonne interlocking concrete blocks, 1200x600x600. These blocks are made from left over concrete from concrete plants and as such will vary in mph, aggregate size and colour. As can be seen in the photos some blocks are made using two different pours each layer is secured to the other. We always (where feasible) recommend inspections prior to purchase.
We have 2 different styles available; the "lego" Style interlocking on top and bottom. The other type has a flat top and bottom with male female cutouts on the left and rights side of the blocks. (see pictures)
The flat top blocks are cheaper to buy and as we source these from all Sydney Hy-tec plants cartage is usually cheaper as well.
Our truck carry’s 14-15 blocks at a time (depending on delivery location) and also has a crane/hiab to unload if required. More blocks can be freighted with multiple trips.
Lifting is done by M20 thread cast into the block with an elephant ear loop they screws in for easy lifting (not supplied) for the interlocking and an engineered loop system for the flat top blocks
Please note that weights are approximate, these blocks are not engineered in any way or vibrated. Use should only be in non-structural applications only, Shantana does not accept any responsibility for these blocks being used in a structural of retaining manner.
