Polyurethane Waterproofing of Concrete Roof Slab

Polyurethane waterproofing is a highly effective method used to protect concrete roof slabs from water ingress and damage. This technique involves the application of a two-pack aliphatic polyurethane system formulated with polyether polyols and isocyanate, which not only provides waterproofing but also imparts flame resistance. The system delivers a durable, glossy, and chemically resistant finish

How to Pour Concrete in Columns and Walls

Pouring concrete in columns and walls is a critical process that requires great caution and attention to detail. Proper techniques are essential to ensure the concrete achieves its designated strength and durability, which directly impacts the safety and longevity of the structure. This article outlines best practices for pouring concrete in columns and walls to

Lap Length of Reinforcement in Columns

In reinforced concrete construction, lap length or overlapping length refers to the length over which two reinforcement bars in a column are spliced or overlapped to maintain structural continuity. This connection technique, known as lap splicing, is essential to securely transfer loads from one bar to another, ensuring the strength and stability of the column.

Properties of Aggregates and Its Values for Use in Construction

Aggregates are one of the most important components in construction materials like concrete, mortar, and asphalt. Their physical and mechanical properties significantly influence the strength, durability, and workability of the final product. This article explores essential properties of aggregates, including bulk density, specific gravity, void content, water absorption, and permissible limits of impurities, along with

Painting a Plastered Surface Guide

Painting the interior and exterior surfaces of a building is an essential step not only to enhance its visual appeal but also to increase its value and protect it from natural elements. Moreover, painting helps conceal any repaired damages, giving the building a fresh and well-maintained look. This article provides a detailed procedure for painting

Post Concrete Inspection and Testing of Concrete Buildings

Post concrete inspection is a crucial step in ensuring the safety, durability, and quality of concrete structures. After concrete is cast and the formwork is stripped, a thorough inspection is essential to detect any damage or defects that may require immediate repair. This process helps prevent structural failures and ensures compliance with design specifications and

Planning and Designing a Water Supply Project

A water supply project is a vital infrastructure that ensures the availability of clean and safe water to a community. Typically, such a project comprises a water collection unit, a conveyance system, and units for treatment, purification, and distribution. Successful execution of a water supply scheme depends largely on thorough planning and design before construction

How to Prevent Plaster Defects in the Construction Phase

Plaster defects can significantly impact both the durability and appearance of a building. Fortunately, most of these defects are easily avoidable when the right precautions are taken during the construction phase. From proper surface preparation to selecting suitable materials and following standard procedures, this article highlights essential measures to prevent common plaster defects and ensure

Plastering Work in Masonry Construction

Plastering is an essential finishing process in masonry construction that involves applying a thin layer of mortar over the surface of brick or concrete walls. This layer not only acts as a damp-proof coating but also provides a smooth and firm surface that enhances the overall appearance of the building. Beyond aesthetics, plastering plays a
