What Causes Voids Under Concrete Slabs? There are many potential causes of voids under concrete slabs. The most common causes are; Erosion. Excess water surrounding a concrete slab causes soil erosion and, eventually, voids. Drainage problems and faulty plumbing are two typical causes of erosion. Soil Settling Another source of voids under a slab is […]
What Is The Average Span For Precast Hollow Core Concrete Slabs? Precast concrete hollow core slabs are an important type of building material used in construction projects around the world. These slabs are designed for a typical span of six meters but can be used with or without a structural concrete topping, depending on the […]
What Are Control Joints In Concrete Slabs? Concrete expansion joint, also known as a control joint, is a gap in the concrete that allows it to expand and contract as the temperature changes. It creates a barrier between the concrete and the rest of the building, allowing for movement without producing stress, which can lead […]
Can You Lay Paving Slabs On Existing Concrete? Yes, you can lay paving slabs on existing concrete. When laying paving slabs over existing concrete, it is important to consider the depth of the base beneath the slab and see how much paving block you need to level out complete paths. Paving slabs require much preparation […]
Does A Hip Roof Need Bracing? Yes. When discussing the need for bracing in a hip roof design, it is important first to understand the inherent design of a hip roof. A hip roof has slopes on all four sides that come together at the top to form a ridge. As a result, a hip […]
Why Do Concrete Slabs Need To Be Earthed? Buried concrete slabs absorb moisture from the surrounding environment and are very electrically conductive. Because the resistivity and permittivity of both media are mostly determined by their moisture content, the concrete in these slabs has nearly the same resistivity as the surrounding soil. As a result, the […]
Why Is Roof Bracing Needed? There are several reasons why roof bracing is needed in order to ensure the stability of a structure. First, roof trusses are designed to support a certain weight and wind pressure. If the trusses are not properly braced, they can buckle under the weight or rotate in high winds, causing […]
How Does Roof Cross Bracing Work? Cross-bracing (or X-bracing) is a system that uses two diagonal members crossing each other. These members only need to be resistant to tension, with one brace at a time acting to resist sideways forces, depending on the direction of loading. As a result, steel cables can also be used […]
What Is The Function Of Bracing In Trussed Roof Construction? Bracing in trussed roof construction is to prevent the roof trusses from splitting or rotating in the so-called “hinge zone.” Bracing roof trusses provide lateral stability to a building’s skeleton, thus preventing distortion and collapse. There are several ways of bracing roof trusses. One common […]
How Much Weight Can Roof Beams Hold? Residential roofs are designed to support a certain weight per square foot. The code typically starts at 20 pounds per square foot but can top out at 100 pounds per square foot. This means that the average roof can support around 20 pounds of weight per square foot, […]
