While concrete is the most popular and versatile material used for construction, it also has several defects. These defects may arise over time in the form of cracks, honeycombs, spalling, excessive deflections, exposed steel reinforcements and other similar distress signs.
The deterioration of concrete structures is happening at an alarming rate worldwide. Even if the structural design has met all the construction standards and quality requirements, there is still a high risk of damage to the concrete and corrosion of reinforced steel.
Corrosion of steel is the most severe cause of damage to reinforced concrete, which can cause cracking and peeling of the concrete shell, reducing the effective cross-section of reinforcement and possibly leading to structural collapse of the structure if not handled quickly.
No one can afford to dismantle old and fragile structures and rebuild new ones as that is not economically feasible and a waste of valuable resources.
As a result, demand for repairs, strengthening, and retrofitting solutions has increased dramatically over the last two decades. The fundamental goal of any structural repair or restoration work is to improve the structure’s performance, extend its service life, or raise its load-bearing capacity.
These situations arise due to several factors like:
- Structural deficiencies due to construction defects, inferior and substandard materials, poor working skills, and quality control and supervision negligence.
- Damages due to fire or natural disasters.
- Chemical deterioration in marine environments.
- Damages from abrasion, wear and tear, impact, dampness etc.
- Concrete movement due to settlement of the foundation, thermal expansions etc.
ECMAS offers a wide range of solutions (ECMAREP) for repairs and restoration like high-strength mortars, micro concrete, rust removers, protective coatings, bonding agents, structural and flexible injections, etc.
