Grading and
retaining walls

These are the primary and most common kinds of retaining walls that are used to hold soil in environments like roads in hilly areas. The material used to create gravity walls is normally concrete, though strong wooden blocks and timber are sometimes used.

These walls use the weight of the wall to give stability against the pressure from the soil and backfills. The walls tend to be created from a higher amount of concrete than other kinds of walls. Reinforced retaining walls are highly traditional.

The structure of this kind of wall contains a slab of concrete which also covers the area below the backfill. The vertical standing wall is also known as the stem and gives support from the base. It stands straight to restrict the force from the soil and backfill.

Counterfort retaining walls are similar to cantilever retaining walls but are economical to the height of 15 meters rather than 10 meters. This kind of wall has a pair of supporting counterforts which enable the wall to withstand more pressure and force.

These walls are walls that can be created on-site, though they can also be manufactured elsewhere and placed on-site. This kind of wall manages the pressure of soil in mountains and is also used to create roads where mountain soil has a semi-vertical angle.

These walls are normally used in excavating sites and in excavating water bodies or areas close to water bodies. The structure has piles closely placed to each other. There can be some or no space between the piles. The piles can be made of timber or some types of metal.

These walls see real nailing being placed in the soil. The design ensures that the walls are able to hold back both the soil and earth pressure. Large nails are dug into the soil before they are covered with the concrete wall.
