What is void ratio? – Void Ratio Formula and Porosity Relationship

In geotechnical engineering and material sciences, a very common concept regarding soil is void ratio. We deal with this concept in hydrogeological properties of soil. If you look at the void-ratio formula you’ll come to know that this dimensionless quantity plays a vital role in different properties of soils. The voids in soil not only … Read more

Expansive soils – Identification – Types – Fixing – Properties – Examples

expansive-soils

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

Retaining Wall – Types – Detail – Gravity – Cantilever – Anchored – PDF

Retaining Wall Types

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

What is wellpoint system? Types – Applications – Advantages

What is WellPoint System?

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

Difference between compaction and consolidation

Difference between compaction and consolidation

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
