How do you cover a retaining wall?
A planted raised bed at the base of an unsightly wall helps hide the wall behind it. This method is useful for the medium-sized garden that can dedicate space to a raised bed. The important decision will be what types of plants you use against the wall. Choose appropriate plants for the microclimate of your wall face.
What is the cheapest retaining wall block?
What is the cheapest retaining wall material?
- Treated pine and is the least expensive material.
- Hardwood is more expensive than treated pine.
- Railway sleepers are another – slightly more expensive – option and are built to withstand ground and water contact.

Should you put plastic behind a retaining wall?
I always run the thicker black plastic behind retaining walls. Preserves the timber sleepers a bit more and stops dirt and weeds coming through the inevitable gaps. +1 for geotex on the ground and up the soil you want to retain, then aggregate between fabric and wall, with drain at the bottom. No plastic for me.
What do you put under retaining wall blocks?
Backfill the wall with gravel or sand. If you use sand, first cover the backside of the retaining wall with landscape fabric. This will keep the sand from seeping between the blocks. If you’re backfilling with gravel, you can pour the gravel after every course you lay.
How can I make my concrete retaining wall look better?
Beautify exterior concrete walls, such as retaining walls, by applying a layer of stucco to create a textured appearance. Add a “cap” to the top of the wall if desired by attaching small slabs of flat, natural stone to the wall top using the correct adhesive.
How long do timber retaining walls last?
A timber retaining wall can last a little over a decade, if treated properly. If not maintained, the lifespan of a timber wall is around 3 to 5 years. To keep its fresh look, timber requires serious maintenance. The material will hold up for so many years only if its pressure-treated with chemicals.
What is the easiest retaining wall to build?
For the average do-it-yourselfer, building a retaining wall is easiest when using masonry blocks that will be stacked no taller than three feet, with no mortar binding the stones or concrete members. (For a curved wall, mark instead with a garden hose or spray paint.)
How long do block retaining walls last?
A concrete retaining wall can be expected to last anywhere from 50 to 100 years. Meanwhile, a brick masonry wall can be expected to last at least 100 years, though the quality of the work will play a role here.
What type of retaining wall is best?
Timber and inter-locking-concrete-block walls are great DIY retaining wall ideas. Mortared masonry and poured concrete ones are usually best left to a mason.
Does a 2 foot retaining wall need drainage?
Although there are exceptions, most retaining walls require gravel backfill, soil compaction, pipe or toe drains, and weep holes. Together, these four features will provide adequate drainage for most designs. Only a few types of walls will not require all of them.
Can I use sand to backfill a retaining wall?
DO backfill correctly.
After your drainpipe is in place, you should backfill the rest of the space behind the blocks with either sand or pea gravel—either will allow water to filter through to the drainpipe at the base of the wall.
Does concrete retaining wall need drain holes?
A retaining wall is like an impervious surface, requiring a drainage hole to let the water through. If you have an eroding slope on your property and you’re thinking of building a retaining wall, keep in mind that there’s a lot more involved than putting up the wall itself.
WHY DO Retaining walls fail?
The main cause of retaining wall failure is poor drainage. Without proper drainage, hydrostatic pressure builds up behind the retaining wall. Saturated soil is substantially heavier than dry soil, and the retaining wall may not be designed to handle such a load.
How high can you build a retaining wall without a permit?
Most municipalities require a building permit and a design from a Licensed Engineer if your wall is taller than 4 feet high (measured from the bottom of the first block to the top of the last block).
How much are large retaining wall blocks?
The cost of retaining wall materials ranges from $3 to $40 per square foot. Wall block prices fall between $10 and $15 per square foot, while precase, poured concrete runs $20 to $25. Wood falls in the middle at $15 to $25 per square foot.
