What Is A Raft Foundation In Construction? Raft foundations are a reliable and cost-effective form of foundation used in construction. It is made up of four foundation piers connected together using a thick concrete slab. The foundation piers are connected through reinforced steel beams, which enable them to occupy the whole area beneath the structure, […]
What Is Floating Foundation? A floating foundation is a type of foundation system used to support structures or buildings that are situated in water, such as docks, wharves, pontoons and jetties. This specialized form of deep-water construction involves using airtight containers filled with heavy material (such as gravel, sand or concrete) that are then floated […]
What Is A Crawl Space? A crawl space is a small, unfinished area located within a building between the ground and the first floor. It is called a crawl space because there is usually only enough room for someone to crawl through it, rather than stand up. Crawl spaces are typically uninsulated and unheated, which […]
What Is Meant By Shallow Foundation? A shallow foundation is a type of civil engineering structure which transfers the load from the superstructure to the ground through direct contact with a small area of soil or rock. It can also be referred to as spread, strip or pad foundations and consists of a comparatively thin […]
What Is A 2 Way Slab in Concrete Work? A two way slab is a reinforced concrete member supported by beams on all four sides, with loads applied along both directions. It is typically used for floor and roof construction and provides greater strength than a one-way slab. Unlike other slabs which have the beam […]
What Is Meant By Deep Foundation? A deep foundation is a type of foundation which transfers loads from the surface to deeper layers in the ground. These foundations usually have much greater depths than regular shallow foundations, and are constructed by driving piles into the ground and then either connecting them together with caps or […]
What Does Underpin Mean In Construction? In construction, underpinning is a technique used to strengthen or support an existing foundation or structure. It involves digging around and under the existing structure, inserting several supports underneath the current foundation and then gradually strengthening them over time. This process helps to increase the stability of the structure […]
What Is An Aggregate Base in Construction? The aggregate base is a type of construction material that is made up of crushed rock particles that are small enough to pass through a screen with 20-millimeter (mm) holes. It can be composed of either newly mined rock or recycled asphalt and concrete. Aggregate base is used […]
What Does Damp Proofing Mean In Construction? Damp proofing is a process that involves using a mixture (traditionally tar or unmodified asphalt) as a coating on the exterior side of a structure and has one main purpose: stopping the transfer of soil moisture into the structure. This is done to prevent rising damp, which is […]
What are Helix Piles? Helix piles are deep foundation systems used in construction to support structures, such as buildings, bridges, and retaining walls, when the soil or rock is not strong enough to support the weight of the structure. They are made of steel and consist of a central shaft with one or more helix-shaped […]
