The use of blockwork allows structures to be built in the traditional masonry style with layers (or courses) of staggered blocks.Ĭoncrete blocks may be produced with hollow centers (cores) to reduce weight, improve insulation and provide an interconnected void into which concrete can be poured to solidify the entire wall after it is built.Ĭoncrete blocks are some of the most versatile building products available because of the wide variety of appearances that can be achieved using them.

For the British TV series, see Breeze Block (TV series). Occasionally rake or shift the sand with the shovel to coax the backfill material into settling. The more compact the backfill, the more stable your wall will be."Breeze block" redirects here.Portion out the backfill material in small amounts to let the material settle. If you shovel in too much at once, you may create hollow spaces in the backfill that can compromise the wall's stability.If you wish, you can leave the drainage backfill slightly lower than the top of the wall, then fill the remaining space with topsoil for planting grass or other plants. The wider the backfill area with gravel or sand, the better your wall will drain.Ordinary soil can be far too dense, creating an enormous weight that puts dangerous stress on the wall. It is very important to use a porous material for backfill, as it will allow water to easily drain away, lessening the weight and force placed on the wall during heavy rains. When the wall reaches its completed height, carefully fill in the space behind the wall using sand or gravel.Wet earth is both hard to shovel into and hard to move. When to build: A retaining wall is best constructed when the soil is dry after a period of no rain.This design causes the wall to angle slightly back into the slope, further improving its holding power. A lip on the back of each block creates a uniform setback as each course is added. Designing the wall with a setback: Concrete retaining wall blocks are shaped in a way that creates a natural setback as the blocks are stacked.For this reason, the space behind a retaining wall is usually filled not with soil, but with a porous, drainage-promoting material such as gravel or sand.
