Retaining Wall

What is a Retaining wall?

You may ask What is a retaining wall? A retaining wall is oftentimes built to provide support, prevent downslope movement or erosion, or hold back soil or rock from a structure or area. However, with their constructive purposes also come creative and design-influenced applications. A retaining wall is a wall which holds back or supports soil when the natural ground level has been altered. When a person ‘cuts’ into the natural ground level, the soil on the high side is to be prevented from collapsing with the use of a wall. A retaining wall is a choice, not a necessity, it’s not like it’s the foundation of your house. Plus the tree was there first, so building a wall there, you’re going to know the roots might affect it.

 A retaining wall is a structure that holds back soil or rock from a building, structure or area. Retaining walls prevent downslope movement or erosion and provide support for vertical or near-vertical grade changes. A retaining wall is a functional feature of your landscape that, when constructed well, can be a thing of beauty. However, a poorly built wall will quickly become an eyesore, even if the best materials have been used. A retaining wall is like a dam: The higher the wall and the heavier the soil behind it, the greater the pressure on the wall. Most retaining walls over 3 feet (2 feet in some areas) are thus subject to some kind of permit process; this is taken more seriously in areas of seismic activity, where walls must be able to withstand shock loads in addition to everything else.

 A retaining wall is generally built in order to retain soil. However, walls can serve aesthetic functions as well. A retaining wall is built to stabilize and hold back soil and/or rock from downslope movement or erosion. Masonry, stone, brick, concrete, vinyl, steel and timber are common materials used for retaining wall construction. A retaining wall is a wall built to rebut the pressure of the earth, either wet or dry. In designing such a wall it is necessary to ascertain the character of the material to be retained.

 A retaining wall is a stabilizing structure used to hold sloping ground in place and to prevent the erosion and the movement of soil. A retaining wall must be substantial and sturdy in a structure in order to accommodate and redistribute lateral pressure caused by sloping. A retaining wall is required if adequate space is not available. Maximum slope steepness is dictated by the quality of fill soil available and whether or not the slope will be protected with riprap to eliminate the need for mowing and other maintenance. A retaining wall is a large expanse of wood, stone, brick, or masonry. Although this may be desirable and attractive, you might want to soften the look by adding plants, yard ornamentation, or a combination of both.

Reinforced walls are usually greater than four feet tall and have special loading conditions present like slopes or surcharges. Reinforcing tie-backs, such as earth auger tie-backs, can be used with high retaining walls. Wall backfill is placed behind the wall for each layer of blocks.

Because these types of blocks interlock together, no mortar will be needed. Another benefit can be when you make an error or even change your mind about the design, just take apart and start over. Firstly decide where you might put the new wall. You should utilize a garden hose in making a shape or even paint a line on the ground. When you’ve got the rough shape, look for a block most appropriate for your shape you’ve chosen. Several types of block create curves simpler and different styles make corners simple. Keep the form of your wall in mind in order to pick your block. Get pamphlets as well as consult with the people in the Garden Department of your local do it yourself shop. You may also discover numerous helpful particulars online. You can estimate the number of blocks it’s going to take to create your wall. You should definitely allow for cutting or breakage. The shade of the blocks may change from batch to batch, therefore if you have to go back and purchase additional blocks, later on, they may not necessarily match up exactly. I advise getting an additional 10 % to be on the safe side.

Here’s The best way To Do It

The initial step in retaining wall construction should be to determine the size or area of the retaining wall by a linear foot. This will figure into the estimate of materials required later on. Mark off the area using a string line and allow for an additional room at the sides of the retaining wall blocks for a decent gravel base.

Estimate the materials needed, chose preferred retaining wall blocks, the size you choose may determine the number needed, for instance: if 12-inch blocks are used the number times the linear foot needed is obvious. If 8 or 16-inch blocks are used, convert total linear distance needed to inches and divide by 8 for an eight-inch block. Estimate base material- gravel(3/4 quarry process) for under retaining wall, use 4- 6-inch gravel base, more if retaining wall is higher in size.

Planning for a great retaining wall construction the base is the most important and will be one of the most time-consuming processes. Excavate by shovel or loader if available, use local digging laws to ensure that you avoid any buried cable. If possible use landscape fabric under gravel for better support and safeguard base from the soil. Some areas may need a deeper base (6 or more inches) because of poor soil or recently disturbed soil from new house construction. Next- get the gravel base in by wheelbarrow, shovel, loader, and rake it out to approximate level.

Grade the retaining wall base using a rake and 2X4 to get an even base where the wall is placed. The string line ought to be in place with a proper level set and the direction of the wall. So when the base is ready and compacted to the correct string level, all you have to do is line the rear flat side of the retaining wall blocks with the string and keep on placing blocks. When installing string line, remember that the first course of blocks needs to be 3/4 buried for good support of the entire wall.

Use a plate compactor or like compaction device to get a good solid base for the wall. If the gravel is too dry, wet it down some using a garden hose to make it pack better. Grade additional times after each compaction until finished.

Lay the retaining wall blocks along the string line until the first layer is finished, be sure you have this first coarse secured perfectly, some bury the first layer almost entirely or 3/4 buried so the base is sturdy. When layer 1 is done, the following course is easier, up to the height you want to allow it to be. Use a landscape block adhesive between every course for additional strength.

Most retaining wall blocks may have to be cut to finish or match nicely to a foundation or other structure. Use a diamond blade chop saw to get a nice cut. measure block in place and cut on your marked line. Retaining wall caps are a good option to use, they add a better appearance and

will not allow weeds to grow between the joints on top of a wall. (depends on the type of block used) secure with a landscape block adhesive for added strength.

Finish the retaining wall construction by adding or backfill any more base material or black dirt in front or behind the wall, seed grass if needed. If retaining wall is located in an area that water drainage is a concern, use a drain tile pipe along the back base of the wall and use a rock or water-friendly material for drainage purposes. Use this on the back of the retaining wall before black dirt or other soil is added.

Tip: Use Landscape Block Adhesive between each course of blocks, run a bead of caulk across the blocks, this will make the wall stronger and moisture will not leak through the blocks, they will be sealed.
