The source of concrete cancer is rust within the concrete slab. As the steel rusts, it expands and displaces the concrete, leading to cracks that further aggravate the problem. Causes:
CES offers engineering solutions for all concrete repair work. We provide clients with problem-specific solutions for repairs, and we ensure that our site crews complete them to their satisfaction.
Carbon Fibre Reinforced Polymer (CFRP) is extremely strong and very durable, allowing concrete structures to be reinforced without having to demolish and replace existing structures. It is applied externally to strengthen concrete beams, suspended slabs, and structural columns without the need to do so.
Based on the location in the structure and the nature of the strengthening required, CES can offer innovative, but proven techniques of incorporating CFRP.
Crack injection is the process of pumping grout or resin into a void to fill the cavities in a concrete slab. Injection works are typically carried out to aid waterproofing or to prevent corrosion of concrete structures. Epoxy Resin Injection is also used to repair structural cracks in concrete to some extent. It is used to structurally re-bond cracks between 0.2mm and 5.0mm wide for vertical, horizontal and overhead that are dormant and relatively dry.
A crack to be filled with resin ought to be thoroughly cleaned to remove all debris and organic matter, including debris adjacent to the crack that may hinder the bond of a seal coat or could obscure the crack’s visibility. The cleaning methods are:
CES offers variety of crack injection solutions depending upon its nature.
Depending on the project, structural steel components can be used to strengthen an existing structure. Structural strengthening depends on several factors including fire rating, aesthetics, and complexity.
At CES, we offer tailor-made engineering solutions that successfully meet our clients’ needs.
As a full Design and Construct solution provider, we can assist you with various structural strengthening solutions best suited for your project.
Corrosion to an exposed steel member is a common phenomenon. The protective coating on structural steel members exfoliates over time, exposing the steel to moisture and causing it to deteriorate.
At CES, we provide full treatment of corroded steel members as well as strengthening solutions.
