Creating pathways and retaining walls are an excellent way to create a unique, natural look to your landscape. They are also effective at helping you to keep water away from your home, garden or pool.


Choosing the right backfill material for a retaining wall is essential to ensure the longevity and stability of your project. Backfill is the dirt or stone used behind a retaining wall. If the backfill is not done properly, the wall can sink or even break, resulting in a costly rebuilding project.

The best backfill material is a mixture of gravel and native soil. The mixture should be sufficiently strong to meet the structure’s needs, but not too heavy to be too difficult to compress.

One way to find out which material is best for your project is to consult a soil expert. They will be able to determine the best mix for your retaining wall, including the best types of gravel for backfill.

When using gravel as backfill, you need to know how to properly lay it out to prevent the settling of the material. The gravel should be graded and compacted so that it will hold up to the lateral loads of the wall.

Angle of the wall

Whether you are designing a new retaining wall or looking for a new design for an existing one, it is important to understand the varying angles that are possible. This is particularly true when dealing with the different materials and methods used to construct the wall. The angle of a retaining wall can be varied depending on the distance D between the wall and the ground.

The optimum angle is usually achieved by building the wall in a way that a particular component of the retaining wall is interlocked to form a 45 degree angle. This is typically done with a combination of upper and lower blocks. The coupling of the two blocks has the effect of preventing any deformations.

The most important component in building a retaining wall Concreters Ballarat is the ability to identify the active and passive ground pressures. This is achieved by analyzing the disturbance parameters of the soil and the underlying backfill. The disturbance parameter for the backfill is 0.35.


Whether you are designing a new retaining wall or renovating one, it is essential that you plan for proper drainage. Without it, water could collect behind the wall and cause damage to the foundation. This could lead to sagging and decaying areas, resulting in an expensive repair job.

In order to build an effective retaining wall, you need to survey the area where it will be installed. During the survey, you should consider the type of soil and slopes that are present. You should also find out how much water there is in the soil during the worst weather.

Depending on your soil type, you may need to back fill the space behind your retaining wall with gravel or native soil. You can also install a perforated pipe to help with drainage.

Limitations in the Pisgah Ranger District

During construction of the new Catawba Falls trail, the Forest Service has announced that public access will be limited to the area until the spring of 2023. This means that hikers will need to cross private property to reach the falls. The Forest Service is required by NEPA rules to keep harvesting of rock in the area out of the trail corridor. If public access is found in violation of these rules, violators could face fines of up to $500.

The Forest Service has also announced that salmon fishing in the Delta River and Porcupine River drainages will be closed until December 1, 2011. Subsistence fishing for grayling is also prohibited from 6:00 p.m. on Monday through Friday, and from 6:00 p.m. on Sunday through Tuesday.
