How to Create Interlocking Blocks?

Posted by Armstrong Louis on January 7th, 2019

Interlocking bricks are the latest innovation in the construction industry, allowing structures to be constructed quickly and easily. The interlocking building blocks in Cape Town is used to construct houses, walls and other structures too. The biggest advantage of these blocks is that they can be manufactured easily by unskilled labourers using minimal resources. Here let us look at how you can create interlocking blocks using their moulds:(Information credit: http://stumbelbloc.com/products/)

1. The blocks should always be manufactured in a shaded area. The blocks can crack due to direct sunlight or extreme temperature variations.

2. Take the mould and properly lubricate its inner surfaces using cooking oil or some similar lubricant. You can apply the lubricant using a paintbrush or even dip the entire mould in the lubricant drum. Spraying is also a possible way of lubricating the mould. This is necessary to ensure that the block can be taken out of the mould easily.

3. Next, you will have to place the moulds in a standing position with their open side facing up. Using the bolts and nuts, join the two halves of the block together. Ensure that both sides have washers for even distribution of the load.

4. Place the mould on a firm and level surface and pour the concrete or cement mixture into it. While you are filling the mould, remember to tap the sides of the mould. This will ensure that the mixture fills in all the cavities of the mould. However, if you are using a vibrating table, there is no need to tap the mould.

5. Once the mixture has filled the mould to the top, give it a shake and tap it. Allow it to sit for a few moments and you will notice that the mixture will settle down. Add a little more mixture if necessary and smooth out the top.

6. After the mould is filled completely, place it on a level surface and allow it to dry. Do not disturb the moulds for at least the next 24 hours or it will cause the mixture filling to crack. Allow the bricks to cure for a minimum of two nights before you attempt to take it out of the mould. If the ambient temperature is below 5 degrees Celsius, do not attempt to make the blocks!

7. Now for taking it out of the mould, run the edge of a small washer around the sea of the mould to loosen the block. Then integrate the larger washer and use to loosen the block further. Slowly pull apart all the pieces of the mould and the block will remain standing.

8. After the block has been successfully removed, leave it standing for twenty-one days at least so it can set properly. You can leave it in the open air or under the sun during this period.

9. Your interlocking building block is ready.

The easy process of creating these blocks does not require any skilled labourer. It can be executed on the construction site itself, using minimum resources. The blocks offer a very cost-effective alternate way of construction.
