Build a Retaining Wall That Slopes

A retaining wall is usually seen in an outer landscape. It is functional as well as adds to the aesthetic looks of your yard or garden space. As a matter of fact, it’s a practical solution for sloping yards. Boulder retaining walls can surely make the whole sloping surface stable, contradicting any fears of soil beds along the collapsing slopes. Aside from that, also helps to restrict erosion of soil and prevents garden soil from overflowing onto your pavement.

A retaining wall along the slope can be installed with various materials. It is usually made from wood, tiles and concrete. In addition to that, there are no certain rules pertaining to the size of the walls or construction method. Installation of the retaining wall is not that complicated however, it is just time-consuming. You may actually do it all by yourself, provided you stick to some basic instructions.

You must be familiar with parameters such as the soil type and the standard depth of ice in your area. Various soils have several possibilities to expand or contract when thawing or freezing. Greater frost depth would mean you’ll have to dig your foundation much deeper. You should always check with your local building rules if a permit is necessary. Proceed once the permit has been cleared.

1. Inspect for Water Overflow

Check areas which have noticeable downhill spots or established water runoff.

2. Mark Your Area

You should mark the area where your wall has to be installed. You may drill some tiny holes around the marked spot and build wooden stakes in them. Then, string masonry twine among stakes.

3. Create a Leveled Trench

With the use of a spade, dig the trench on the upper portion of the marked retaining wall spot. Throw some colored stones in the trench and level it with a rake. With a tamper, press the stones to make a level surface.

4. Install the Concrete Layer

Begin putting the concrete bits above the stones. Make use of the torpedo level to make sure that your concrete is precisely leveled on all portions. Concrete units have to be laid and synchronously leveled on the stones.

5. Interlock the concrete

Put the interlocking stones at half the original concrete layer length, in every tier.

6. Backfilling

Begin putting the landscape fabric prior to adding gravel as the replacement to the standard soil. With the use of a spade, compress at least 4-inch layer of gravel on the concrete.

7. Check the Concrete to Slope Ratio

You must have at least 1 inch of sloping gravel in every 4 feet of concrete.

8. Establish Drainage

Put your four-inch drainpipe in the gravel. This step completes the 1st layer of your wall.

9. Extend Your Wall

Continue putting the layers of interlocking blocks, concrete, and then shoveling the backfill. Push down your landscaping fabric and then add topsoil when the needed height is achieved.

10. Check the Created Slope

The angle of the topsoil must be sloping downwards.
