How to set concrete block wall.
Cinder blocks are a great tool for building garden walls or storage structures in your yard.
Next prepare cement mortar by mixing water and dried mortar in a 5 gallon bucket.
For example if your cinder blocks are 8x8 in 20x20 cm and you want to use 2 blocks to make up the wall s width your total wall width would be 16 in 40 cm.
Step 12 using a mason s line as a guide for the remaining block continue building the wall until it is complete.
Check both the tops of the blocks and the outside edge.
Stretch a line with mason s blocks between the leads.
Then spread the mortar on the footing and begin stacking the blocks beginning in a corner.
To set the next course of block apply a one inch thick mortar bed along top of the first course.
Never attempt to move a block after the concrete begins to set.
If the area where you are planning to use the cinder blocks is already covered with a concrete pad you can easily build a cinder block wall right on top of the concrete.
To determine the width of your future wall decide how many cinder blocks you want to use for the wall width then calculate the width using the block s measurements.
Foundation all concrete block walls must rest on a sturdy foundation of poured concrete.
Step 11 at the end of the wall set an 8x8x8 half block into the mortar bed with the smooth side facing out.
Grab the block by the.
Lay a mortar bed on the footing between the leads and set the block working from both sides to the center.
To lay concrete blocks begin by building a frame with 2x4s and pouring concrete into it to prepare a footing.
Once several concrete blocks have been laid use a long level to verify the alignment.
Set the line 1 16 inch from the face of the block and level with the top of the first course.
The depth and size of the foundation will vary depending on the size of the concrete block wall and the weight it must support but a typical freestanding wall requires a foundation that is about twice as wide as the wall itself and which extends about 1 foot down below the frost line.
Follow the block manufacturer s instructions for wall height limits.
Avoid having downspouts pointed at the retaining wall and if it s against the house keep soil and mulch well below the siding.
