Build Retaining Wall Blocks Nz In 6 Easy Steps

Footing Construction And Preparation

Layout the wall and dig the footing trench and slope. Build the footing and place rebar at intervals that match the cores in block foundations while concrete is wet. Build leads by preparing the footing, spreading mortar, and sliding the block over the rebar as needed.

Weep Holes Should Be Inserted

Insert weep holes (3/4-inch pipe) into the mortar every third block as you lay the second course of blocks. Chip a tiny depression in the block and trowel a pipe bed, sloping it slightly toward the front. Then, on the next block, chisel out a recess, butter the ears, and set the block.

Remove Any Excess Mortar With A Scraper

Check the mortar now and then. Scrape off the excess with an upswing of the trowel’s edge when it starts to set up little. As you remove the excess mortar, make sure not to seal the weep holes

Set Up The Landscape Fabric

Spread landscape fabric over the soil behind the base of the wall after you’ve put in at least two courses, temporarily placing the excess over the grass on the slope. To keep the fabric in place while you work, place rocks on it.

Backfill the wall with gravel between the back of the wall and the slope, then lay perforated drain pipe on the gravel bed level with the top of the first course. Turn your back on the holes.

Drainpipe Cover

More gravel should be shovelled on top of the drainpipe. As you add courses to the wall, backfill with more gravel. Backfill with soil after folding the landscaping cloth over the gravel fill. Sod should be replaced.

Fill The Container With Mortar.

Fill those cores with rebar to the top with mortar when you reach the finished height of the concrete-block retaining wall. Make the fill mortar somewhat wetter than the joint mortar. With a trowel, smooth the top. To finish the wall, apply more mortar and a cap block.
