  • Interlocking concrete blocks with trapezoidal shape
    Patent number: 9021762
    Abstract: The present invention relates to concrete blocks or cement blocks that are shaped along the front surface like a wood shingle. In this way, when a user builds an outside wall out of these cement blocks, water will run down the side of the wall and not get into any of the joints where one block connects with the other. The blocks are all pre-made, sent to an end-user, and the end-user stacks them to create a wall.
