Backfilling, Soil Compaction
What Are The Different Types Of Fillers Used In Backfilling?
There are many types of backfilling projects to choose from, and the type that you choose will depend on the type of soil you have and the condition of your landscaping. If you have sandy soil with high clay content, backfilling with sand or other fillers may be in order. San Diego Excavation has numerous products for backfilling sandy soils. Backfills can help prolong the use of a newly excavated area as well as add additional fillers that will help make the soil firm and less permeable.
Sand is one of the most popular materials for backfilling. It works well in coastal areas because of its high sand content, which creates a coarse texture that holds well together with little permeability. Sand particles are big enough to move around under the soil, but small enough to keep from getting buried by the larger soil particles. Sand can also add a sandy look to light-shaded areas.
For medium to heavy clay soils, backfilling with silt or clay can be used. Clay soil contains lots of pockets and pores where water and other nutrients can penetrate. Soil particles of clays and silts stay in these tiny spaces and do not move around as much as sand would. In addition, they tend to hold more moisture than sand particles would. This makes them a good choice for moist soil. However, they are also more expensive and harder to work.
If you backfill in clay soil, you should still use silt or clay. However, you may want to use both. As long as the top layer of soil is packed with these larger soil particles, they will stay in place and work their way into the holes left in the ground by the excavated area. It is very hard for smaller ground level backfilling materials to penetrate deeply enough into clay soil to work. You will need to work them in from the sides or back. You may find that your soil has pockets or keyholes along the sides of these holes.
Backfilling with sand and silt is best when you have a huge area to fill. When you are just starting out, you may also want to use fillers with larger particles. These will work better in loamy soils and in soils that are more clay like. These fillers will also work in sandy soils. When you are starting out, you should use fillers that are made from natural materials. These materials will be gentler on the environment and give your lawn more character.
Natural fillers include shell, stone chipping, natural slate, river stones, and even animal pelts. They come in many forms such as small pebbles and even pebbles that look just like marble. They can be manufactured from a variety of natural products and are quite beautiful. Natural slate fillers are an excellent choice for landscape projects because they are quite inexpensive. They do not need to be replaced and they do not break down like other fillers.
Backfilling with rocks or gravel is also an option. They can add a very natural look to the lawn. It is important to know the texture and level of the area before you begin backfilling. When you are backfilling, it is important to add the soil in layers. This will help keep the grass cut short because it does not have to stretch so far. You should also make sure that you have filled all the pockets in the soil.
Backfilling should not be done too often. If you are not using it then remove it in the winter and let it sit until the spring. By doing this, you will allow the soil to add water and nutrients to the grass roots.
