Step 1
Dig a trench for the ground where you are building the wall . Dig the trench at least double as wide as the breeze - blocks , and twice the height of the blocks , or below the frost pipeline , whichever is deeper . Your local zoning dining table can tell you how deep the frost line is in your country .
Step 2
Build a shape for the basis by driving wooden stakes into the ground a few inches inside each paries of the trench and nailing 2 - column inch by 4 - inch plug-in to them . Place a stage across the boards , and tap down the higher boards with a rubber mallet to take down them out , if necessary .
Step 3
grasp a small drainage trench next to the main deep . Add an inch of slope to the trench for every 20 feet of run ( duration ) .
Step 4
Step 5
Pour 2 column inch of low gravel into the bottom of the oceanic abyss and pack it down , then lay drain tile over the gravel . fulfill the oceanic abyss with crushed rock , insure the drain tile . Drain roofing tile is plastic piping that has yap reduce into it for drainage .
Step 6
Pour concrete into the form , filling it until it ’s above the top of the manikin . Depending on the size of it of the wall , you may require to hire a contractor who will rain cats and dogs the concrete from a truck .
Step 7
Slide a 2 - in by 4 - column inch board over the top of the shape to smooth the Earth’s surface of the concrete and expose spots where more concrete is want . add up concrete if necessary , and drag the board over the form again . Allow the concrete to set for at least four days .
Step 8
Step 9
transfer the wooden conformation from around the footing , and backfill the gap between the ground and the deep bulwark with dirt .
Step 10
labor three wooden stake around each quoin of the ground . Place one stake right away behind the corner and one stakes along the foothold 2 foot down from the nook . Nail 2 - inch by 4 - inch display board to the post along the top edge .
Step 11
Tie a string to the centre of one of the 2 - in by 4 - column inch boards , then take it down to the react 2 - in by 4 - column inch board on the next corner and tie it to the center . Do this on every corner . The point where the strings intersect indicate the footing ’s exact corner .
Step 12
Step 13
Lay the turning point blocks onto the footing so the stunned edges line up with the point where the strings intersect .
Step 14
office blocks onto the footing in between the corner blocks , keeping a 3/8 - inch break between each pulley-block to take the breadth of the trench mortar into account .
Step 15
Mark the outer edge of the blocks onto the terms , then remove the occlusion .
Step 16
Mix a batch of mortar , following the maker ’s didactics .
Step 17
Place the howitzer onto the footing in one of the corner with a trowel . utilize the mortar in a layer 1 inch deep , 8 inches wide and about three city block - length down the terms from the corner .
Step 18
Place the first corner pulley-block into the mortar , line it up so the verboten corners are aligned with the intersecting chain . lay a grade across the top of the block , and position the closure until it is even .
Step 19
Step 20
Apply trench mortar to the side of the first breeze - block and range it into the mortar next to the turning point block , keeping a 3/8 - inch gap between the block . Place the level across both block , and even them out if needed . go under blocks onto the footing where you have apply the trench mortar , then repeat this pace on the other side of the corner .
Step 21
Set the occlusion in the other corners using the same method acting .
Step 22
consist the pulley block on the terms between the corner blocks . Apply mortar to the terms as you go , keep a 3/8 - inch break between the blocks and check them for storey as you lie them . If you need to reduce any mental block to fit , tick the emasculated line on the block and cut it with a hammer and Freemasonry chisel .
Step 23
Step 24
lie the cube until the wall reaches the desired height , start in the street corner and working in towards the gist . Allow the mortar to set for the meter specified by the manufacturer .
