Concrete weight blocks

Picture of Concrete weight blocks
I had to find a way to sink some pilings into the ground in the water and after so long they became boyant. In order for them to sink make these concrete blocks to weigh down the pilings so I could put them in all the way. It is a quick, simple, and cheap way to make weights and only costs about $10. I thought that you could use them for almost anything and one things for sure, their not going anywhere because these things are HEAVY! 

Materials needed: 
4 hollowed out cinder blocks 
4 bolts with holes in them and washers and bolts for them. 
1 bag of quick mix concrete

Step 1: Mixing the concrete

Add the amount of water that is suggested on the bag of concrete. Then mix about 1 1/2 gallons of the concrete to go into the blocks to give it its weight. (Tip, stir the concrete a lot to get all of the dry mix to turn into concrete) Put wax paper underneath  of the block so the concrete won't  stick to the floor. Then add the concrete to the cinder blocks, make sure you have something to pack the concrete down with so it becomes more heavy.

Lastly, put the washers on the end of the bolts and put the nut on the end of them. Then push the bolt into the concrete and cover up the hole with concrete and let it sit overnight. In the morning you will have concrete weights that you can use for almost anything.
