1. set up wooden stakes and nylon strings to represent the height and perimeter of the retaining wall. 2. stretch another level line near ground to represent the top of the first course of landscaping timbers. 3. dig a 12-inch-deep trench around perimeter of retaining wall. 4. use a hand tamper to compact the bottom of the trench. 5.
insert one end of a pvc sleeve into one of the weep holes. hold a wooden block flat against the outer end of the sleeve and hit the block with a steel mallet to install the sleeve so the outer end is even with the face of the wall.
this is a video of me using tapcon concrete screws. i wanted to secure two pieces of wood to the cinderblock in my garage. i secured the first 2x4 to the cinderblock without filming the process
how to install a wooden retaining wall. hey folks went to seven trusts today and picked up some landscaping timbers to start the retaining wall that will support the rest of the gravel for the area
dig a foundation trench for the first row of timbers image 3 . make the trench about 8 inches deep. the base of the retaining wall should be half the wall's height. so, in our case, 1 foot wide for a 2-foot high wall image 4 . tamp to a level base. one of the keys to a successful wall is a leveled foundation.
i started setting up a retaining wall just to see how it will look. nothing has been attached yet. what is going to be the best way to attach and secure the wall to the cement slab to prevent it from moving after a wisconsin winter? the wall will end up going 16 feet to the left and 7 ft the other direction from the 90 degree joint.
gravity, along with the slope, directs most of the weight and pressure of the fill toward the lower part of the retaining wall. since soil weighs a beefy 100-plus lbs. per cu. ft., you need some pretty heavy materiallarge retaining wall blocks, boulders, timbers or poured concreteto counteract the pressure.
the two kinds of concrete fasteners we have are a 2-1/4' screw and a 3-1/2' screw. if you use the 2-1/4' screws i would recommend using eight per anchor and only 4 of the 3-1/2' screws per anchor. the holding power is immense so that will not be your weakest link. i guess you will have to choose whether you want to use a 6x6 post or a 4x4 post.
timber walls 4 feet or higher should be tied to the hillside with 'deadmen' anchors 6-foot-long, t-shaped tiebacks buried in the hillside attached to the wall every 8 feet, extending 6 feet back to a 2-foot-wide t-bar.
it will be your most stable option. then, you can sister another 4x4 to the back of those that sites on top of the retaining wall so your fence will be in line with the top of the wall. it will look awesome too. those post bases you posted are crappy. they get wobbly over time and the welds break.
the double expansion anchor comes in six diameters starting at 1/4 through 3/4. machine screw anchor is best used in the solid section of a cinder block because it requires the bottom of the hole to be used for proper setting and expansion. the machine screw anchor needs to be set using a setting tool.
secure the corners together using screws designed for pressure treated wood. the chemicals in the wood would destroy other types of screws. stack the second layer of timbers on top of the first layer. repeat this process until the stack reaches the desired height. check the wall or flowerbed for level during this process.
the word course means one row or one layer of the materials of which the wall is made. drill two half inch holes through post centered 4 feet 1.2 m apart. hammer the post in place with rebar through the holes. hammer rebar until flush with top of 4x4 post.
lastly, the type of fastener required for the application must be determined. there are four options available that can be used in concrete block: 1 stud-type anchor: where the stud will stick out from the wall. example: sleeve anchor 2 hammer-type anchor: where the stud does not protrude from the wall, for a finished look.

step 4. install a concrete drill bit, the size of the screw, into a hammer drill. place a piece of painter's tape on the drill bit to indicate the depth needed to drill. this will be the length of the screw minus the depth of the wood plus 1/4 inch.
