Expansive soils are a nightmare for foundation experts and geotech engineers. They cause significant damage to lightweight structures like sidewalks and driveways. They can uplift building foundations and can result in damage of basements. As a result of settlement upon drying, expansive soils can result in cracks of walls and ceilings.Our today’s read is about … Read more
Caisson foundation which is also called pier foundation is a watertight retaining structure that is made up of timber, steel, and reinforced cement concrete (RCC), and constructed for the foundation of bridges, piers and dock structures. Basically, the word Caisson is derived from word caisse which means a box-type structure or a watertight chamber that … Read more
Retaining walls serve an important role in getting hold of earthfill or an embankment just as dams hold water. The granular material such as soil and rocks applies horizontal pressure that increases linearly with depth. So, retaining walls are designed to resist these forces. Definition Apart from retaining walls, there are so many other techniques … Read more
So, in our today’s blog we’re going to take about the one of the most common types of foundation used in home in Southern United States. Moreover, we’d also look at the reasons why we choose a pier and beam foundation. Well, when you’re going to build a new home, one of the most basic … Read more
It is one of the most widely used soil compactors used by contractors and builders worldwide. The sheepsfoot roller is a piece of heavy self-propelled equipment usually mowed and runs in a static position. Depending on the character of the soils, this sort of roller is available in several sizes. It is one of the … Read more
While undertaking deep excavations for construction of foundations, engineers face difficulties in terms of expulsion of subsoil water. That’s where a wellpoint system serves as the best dewatering tool for lowering the water table below excavation levels. A wellpoint dewatering system consists of a series of shallow wells, known as wellpoints. We install these wellpoints … Read more
So, you’re confused about difference between compaction and consolidation. Well, civil Engineers deal with these processes in geotechnical engineering and soil mechanics. Both consolidation and compaction is a way to reduce the volume of the soil but are quite different in some ways. Though both processes tend to improve the engineering properties of soil but … Read more
Sand Cone test is a compaction test to measure density of soil in the field. You can obtain in-situ density of natural soil. The test is suitable for determination of the dry density of compact, fine, and medium-grained soils. Sand Cone test is also referred to as Sand Replacement method in India and Pakistan. That … Read more
Dry density is an important concept in geotechnical engineering. When you’re in the field for soil compaction, you need to know the parameters that affect the dry density of soil. You might also be looking for related terms like dry unit weight of soil, bulk density of soil, or density of soil solids. Definition of … Read more
Do you know the Atterberg limits define the three critical water content limits of a fine grained soil? Yes! Atterberg limits are consistency limits of soil that define the water content at which the soil changes from one state to the other on addition or removal of water content. Fine-grained soil, especially clayey soils changes … Read more
