Ablock retaining wall might be just what your landscape needs if you want to level a steep slope or enclose an area for a decorative garden, as this video explains. With a little effort, you'll have a beautifully landscaped area that's easy to maintain. The finished product looks complicated, but the project is quite simple, requiring only basic tools.
These concrete retaining blocks interlock and require no mortar. Aside from the weight, they're almost as easy to assemble as children's interlocking blocks. If you make mistakes or change your mind about the location or shape of your wall, just dismantle it and start over.
Since these systems use no mortar or rebar reinforcement system, they're more appropriate for terraces or raised beds with low walls than those with tall walls. A system of terraces creates a pleasant, stepped slope that's safer than a single, tall wall. A system of terraces also gives you many planting and landscaping opportunities.
Retaining wall blocks in mortarless systems have a lip on the bottom rear side to lock the blocks together and create a step effect. When the cavity behind the wall is filled with soil, the blocks are pushed forward, strengthening the joints between the lips and the underlying blocks. The blocks are tapered from the front face to the rear to allow easy formation of curves.
Mortarless wall block is intended for construction of relatively low walls. Taller walls can be constructed but further consideration must be given to drainage, reinforcement and stability. Recommended dry-fit heights vary by product but for general reference, consider 15 inches to 28 inches as a guide for planning purposes.
Consult the manufacturer's instructions concerning height limits or recommendations made by the manufacturer.
The key to successful retaining wall construction is a level foundation of blocks. The foundation course must be at below-ground level so that the soilholds it firmly in place.
If your property slopes, you may have to dig your foundation trench in a series of steps equal to the height of the blocks. Then, as you continue with construction, build up the lower sections with block until the stepped areas accept successive courses of blocks in a level and seamless wall.
Measure out your prospective wall, using stakes and string to mark off the key points, or use a garden hose to mark off its perimeter.
Starting at the lowest point, use a flat-pointed shovel to dig a trench for the foundation course. The dimensions of the trench will vary depending on the size of your block generally about 4 inches deep. The foundation course should be below-ground level.

A retaining wall is a structure that holds or retains soil behind it. There are many types of materials that can be used to create retaining walls like concrete blocks, poured concrete, treated timbers, rocks or boulders. Some are easy to use, others have a shorter life span, but all can retain soil.
Several questions must be considered in order to build the proper type of retaining wall. For example, is the soil sand, clay, or something in between? What is above the wall: a driveway or something heavier like a pool? Will the ground above or below the wall be level or sloped? What is the height of the wall? All of these factors will determine whether you will need a Gravity Retaining Wall or a Geogrid Reinforced Retaining Wall.

Retaining walls are structures designed to restrain soil to unnatural slopes. They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses.
A retaining wall is a structure designed and constructed to resist the lateral pressure of soil when there is a desired change in ground elevation that exceeds the angle of repose of the soil.[1]
A basement wall is thus one kind of retaining wall. But the term usually refers to a cantilever retaining wall, which is a freestanding structure without lateral support at its top.[2] These are cantilevered from a footing and rise above the grade on one side to retain a higher level grade on the opposite side. The walls must resist the lateral pressures generated by loose soils or, in some cases, water pressures.[3]
Every retaining wall supports a wedge of soil. The wedge is defined as the soil which extends beyond the failure plane of the soil type present at the wall site, and can be calculated once the soil friction angle is known. As the setback of the wall increases, the size of the sliding wedge is reduced. This reduction lowers the pressure on the retaining wall. [4]
The most important consideration in proper design and installation of retaining walls is to recognize and counteract the tendency of the retained material to move downslope due to gravity. This creates lateral earth pressure behind the wall which depends on the angle of internal friction (phi) and the cohesive strength (c) of the retained material, as well as the direction and magnitude of movement the retaining structure undergoes.
Lateral earth pressures are zero at the top of the wall and - in homogenous ground - increase proportionally to a maximum value at the lowest depth. Earth pressures will push the wall forward or overturn it if not properly addressed. Also, any groundwater behind the wall that is not dissipated by a drainage system causes hydrostatic pressure on the wall. The total pressure or thrust may be assumed to act at one-third from the lowest depth for lengthwise stretches of uniform height. [5]
Unless the wall is designed to retain water, It is important to have proper drainage behind the wall in order to limit the pressure to the wall's design value. Drainage materials will reduce or eliminate the hydrostatic pressure and improve the stability of the material behind the wall. Drystone retaining walls are normally self-draining.
As an example, the International Building Code requires retaining walls to be designed to ensure stability against overturning, sliding, excessive foundation pressure and water uplift; and that they be designed for a safety factor of 1.5 against lateral sliding and overturning.[6]
Gravity walls depend on their mass (stone, concrete or other heavy material) to resist pressure from behind and may have a 'batter' setback to improve stability by leaning back toward the retained soil. For short landscaping walls, they are often made from mortarless stone or segmental concrete units (masonry units).[7] Dry-stacked gravity walls are somewhat flexible and do not require a rigid footing in frost areas. Home owners who build larger gravity walls that do require a rigid concrete footing can make use of the services of a professional excavator, which will make digging a trench for the base of the gravity wall much easier.
Earlier in the 20th century, taller retaining walls were often gravity walls made from large masses of concrete or stone. Today, taller retaining walls are increasingly built as composite gravity walls such as: geosynthetics such as Geoweb cellular confinement earth retention or with precast facing; gabions (stacked steel wire baskets filled with rocks); crib walls (cells built up log cabin style from precast concrete or timber and filled with soil); or soil-nailed walls (soil reinforced in place with steel and concrete rods).[8]

The Telugu Desam Party (TDP) leaders staged a Jala Deeksha demanding that the State government construct a retaining wall to protect people from the floods in river Krishna.
The TDP leaders stood in waist deep water in the river at Pushkarghat here on Monday to register their protest against inordinate delay in construction of the retaining wall. TDP Vijayawada (East) in-charge Gadde Rammohan Rao said that the TDP government had commenced construction of embankment for river Krishna from Vijayawada to Avanigadda to protect the people living in the vicinity of river. The objective was to protect the people from flash floods and also provide road facility to remotest village. The TDP could construct a bridge near Avanigadda. But, the project was shelved as soon as the Congress came to power. The people were forced to fend for themselves, he alleged.
The ruling Congress had been making false promises about the construction of a retaining wall on the river bank. There was no progress during the last nine years. The TDP would continue the agitation for the retaining wall, he added.
Medical camps
TDP Urban Mahila president Chennupati Usha Rani and others were present.
Meanwhile, TDP organised medical camps at 57 and 58 divisions to cater to the needs of residents of Rajiv Nagar, LBS Nagar and other surrounding localities. The camps were organised under the aegis of NTR Trust Bhavan. The people were screened for viral fevers and medicines were distributed to the needy.
