Mar 01, 2009· Damage also occurs through compaction of the soil from heavy equipment repeatedly driving over the root zone or construction supplies being stored under and around the tree. Compaction of the soil reduces the pore space between soil particles, eliminating the oxygen in the soil which causes root death.

🕑 Reading time: 1 minute Compaction is the process of expulsion of air from the voids present in the soil. In the construction field, it is an important process as it improves the engineering properties of soil to a great magnitude. Effects of compaction on different properties of the soil are explained in this article.

soil becomes friable and granular, making it easier to work and compact (Figure 4). At this stage the Plasticity Index of the soil decreases dramatically, as does its tendency to swell and shrink. The process, which is called "flocculation and agglomeration," generally occurs in a matter of hours. Figure 4: Lime flocculating clay 3.

With proper care, trees moderately affected by construction damage will recover. Homeowners can help trees recover by practicing annual tree care as outlined in the following: Aerate the soil. Pull out cores of soil 12 to 18 inches deep to aid movement of oxygen and …

During your construction activity, do you excavate soil? If the excavated soils contain a haz-ardous substance (e.g., pesticides or petroleum), you may be responsible under CERCLA as an operator, arranger, or transporter. For example: • You may be an operator if you spread soil that contains a hazardous substance on the land.

Soil pH is a measure of soil acidity or alkalinity. It is an important indicator of soil health. It affects crop yields, crop suitability, plant nutrient availability, and soil micro-organism activity which influence key soil processes. Soil pH can be managed by measures such as applying the proper amount of, …

Construction or demolition work, mining operations, or poor landscaping efforts can make soil dust. Breathing in contaminated dust may cause physical or chemical damage to humans. For example, asbestos fibers can puncture the lungs.

Soil surveys can provide a great deal of valuable geotechnical information in rural and agricultural areas. Atterberg Limits The Atterberg Limits (ASTM Test D-4318) define the ranges in moisture content that a soil will behave as a solid, plastic and liquid. The Liquid Limit (LL) of a soil is defined as the moisture content above which

Nov 20, 2017· Loam is a type of soil formed from several other materials, including: Clay. Silt. Sand. The combination of these materials provides important advantages when it comes to constructing concrete foundations. Since clay doesn't dominate the mix, fluctuating water levels at the construction site will not lead to an increased risk for cracking.

Sep 08, 2017· Soil Problems Found in Construction-Damaged Soils. Soil compaction, high (alkaline) or low (acidic) pH, and simply the amount of fertile soil available for root growth are three serious concerns when planting in constructed landscapes such as parking lots, patios, sidewalks, and compacted yards stripped of their organic horizons.

time frame of one farming generation, little apparent harm is done to the soil's mineral framework by permitting acidification of weathered soils. However, it is clear that permitting unabated acidification over longer periods will cause the soil to continue losing clay and to increase its silica content.

Construction sites are found both within urban and rural areas, often in the close proximity of homes. Due to their proximity to homes and the materials used, construction sites may generate home pollution. This involves air, water, soil, and/or noise …

Land use change and check-dam construction have been widely considered as the major measures to reduce soil and water loss. However, whether catchments behave as sources or sinks of soil carbon and nitrogen based on the combined performance of land use change and check-dam construction in sub-catchment systems are still poorly known.
