Polyjacking is a concrete lifting and leveling method that uses high-density geo-technical expanding foam to raise and stabilize concrete surfaces. A similar process with the same objective is the process of mudjacking, which uses mud instead of foam to lift the concrete surface to the desired level. This article discusses the major features and benefits […]

Foundation heave is the upward movement of the expansive soil layer after it is saturated with water. Controlling the signs and symptoms of foundation heave at an early stage is important to prevent further enlargement of heave pressure and avoid serious damage to the foundation and superstructure. Common signs of foundation heave are cracked and […]

Early-age cracking is a temporary shortcoming that crops up as a result of a faulty design and construction process. Such cracks can be repaired properly if necessary actions are taken on time. They can lead to many non-structural and structural issues if not repaired properly, for instance, loss of aesthetic appearance of a concrete surface, […]

What are the Causes of Early-age Cracking in Concrete?

Madeh Izat Hamakareem — Fri, 12 Aug 2022 18:24:47 +0000

Early-age cracking is observed during the first seven days after concrete pouring. However, such cracks may also take more than a week to be visible in reinforced concrete slabs. Therefore, cracks appearing within 60 days after the concrete placement are considered early-age cracks. The early-age cracks do not cause structural failure in concrete if the […]

Dynamic Cracks vs. Static Cracks: Effects and Repair Techniques

Madeh Izat Hamakareem — Fri, 24 Dec 2021 05:57:55 +0000

Any concrete structure would eventually see cracks and demand proper repair. Nonetheless, one needs to understand the nature of the crack to repair them properly. Generally, cracks are either static or dynamic. The former is primarily aesthetic and may or may not need repair, whereas the latter endangers the structure’s integrity and requires adequate repair. […]

Unsound concrete can be identified through various signs such as visible cracks, micro-cracks, spalling, scaling, blisters, and delamination. Multiple factors lead to different types of damages, and as a result, a specific repair strategy may be required for each type of concrete damage. Major Signs of Unsound Concrete 1. Visible Cracks Visible cracks are the most […]
