OUR RETAINING WALLS PRESENT A DUAL BENEFIT, AS THEY ENHANCE YOUR BUILT STRUCTURE -
AND PROTECT IT AGAINST SOIL OR WATER.
Typically, the purpose of a retaining wall is to bilaterally prevent soil or water from encroaching on built developments, civil works structures or landscaped areas, and specifically to a steep slope that it would not naturally keep to.
At EIS, we fuse engineering, architectural and aesthetic principles to ensure we construct structures that are both functional and visually appealing. We humbly believe that the myriad of retaining walls constructed by us around the country, is a testimony to exactly that. To view some of them, simply click on ‘Our projects’ below. .
Types of retaining walls
A general misconception that exists, is that precast concrete retaining blocks on their own, are sufficient to retain soil. In reality, efficiency and durability is achieved by expertly strengthening it with a variety of interlocking materials such as geosynthetics as well as other reinforcement solutions.
Factors that determine what kind of retaining wall will be most suitable vary from site to site and include the likes of the stability of the in-situ embankment, on-site placement, drainage, foundations, batter, etc. This also means that no two retaining walls can be the same.
For this reason, we at EIS first conduct a comprehensive site inspection, situational and environmental analysis before we engineer the final retaining wall for it. The retaining walls featured below, are just some of the solutions we would consider.
Terraced Retaining Wall
A terraced retaining wall is usually built on a slope or curved area where there are civil engineering complications that prohibit the use of other retaining solutions. Because the different parts of a terraced retaining wall are staggered on each other, it almost resembles a series of steps. Some of the key advantages of terraced retaining walls are that they are not only functional, but they also create more ‘green space’ for landscaping purposes, which makes for a significantly more visually appealing structure.

Concrete Retaining Walls
Even though concrete retaining walls are a common choice, EIS more often than not propose alternative retaining wall structures such as closed-faced or open-face retaining walls, or a combination thereof. The reason being that these alternative structures present a league of additional advantages, such as increased stability, improved speed of construction, enhanced aesthetics and greater cost-efficiency.

Closed-Faced Retaining Walls
A closed-faced retaining wall is a type of segmental retaining wall that comprises interlocking concrete blocks that are placed in a closed-face configuration to retain sloping soil and provide a solid, vertical front - that will prevent the soil from sliding, slumping and caving in. Subject to the block design, closed-faced configurations are globally regarded to be more stable than open-faced configurations, because they typically require more blocks per square metre of wall, are fully filed as specified, and are heavier as a result.

Open-Faced Retaining Walls
Subject to the site conditions and application, open-face retaining walls can be a more cost-effective choice, as it typically requires less blocks per square metre. A major advantage of this type of retaining wall is that the open spaces can be increased to create a more open and permeable facing, which in turn helps to prevent accumulation of excess pore water pressure behind the structure.
