Structural Remediation is the most cost effective approach to prolong or extend the life of a critical asset such as highway, bridges, tanks, boats, pipes, etc. AFL delivery the structure remediation on both steel and concrete.
For concrete, AFL perform the following services:
- Concrete Repair reduce the rate of deterioration due to the corrosion of reinforcement and the resulting volumetric changes associated with the corrosion effects which may lead to further cracking and spalling. Depending on the width of the cracks, different methods will be used to repair the concrete.
- Structural Strengthening is the process of upgrading structures to improve the performance under existing loads or to increase the strength of structural members to carry additional load. AFL is experienced with two types of product: Carbon Fibre Reinforced Polymer (CFRP) and Steel Reinforcement.
- Cathodic Protection is the primary solution for preserving reinforced concrete structures. Cathodic Protection can increase the lifespan of a structure such as bridges significantly.
- Shotcrete Application is an extremely versatile material that can be easily and rapidly applied to provide a cost-effective means of construction. It forms an excellent bond to a number of substrates including rock, concrete, masonry and steel. It is suited to a wide range of ground-support applications, linings, and building structures.
SPECIALTY PROTECTIVE COATINGS
For steel remediation, AFL could perform:
- Column & Beam Repairs occur when a steel structures such as column(s) or I-beam(s) can lose thickness due to corrosion. AFL is experienced in repair of these structures by cutting out the damaged sections. New steel plate is welded in the damaged section. After surgical works AFL will blast and paint the section to ensure the steel is being protected from further corrosion.
- Protective Coatings are the most common way to reduce corrosion by limiting the exposure of the metal to a corrosive environment. AFL is experienced in the application of paint to multiple substrates such as steel, wood, concrete, or even in some cases plastic. Moreover, AFL also provide a complete coating system for all structure remediation from the following manufacturers:
- International Paints
AFL Services does a broad range of protective coating including:
- Organic and inorganic zinc-rich
- Fiber glass
- Conductive or non-conductive
We have a partnership to complete the automotive vehicles for Defenses including buses for private sector, and trains for Department of Transport.
CONCRETE REPAIRS – STRUCTURAL OR DECORATIVE
Span from retaining walls to block feature walls to rendering to texture coatings. AFL completed a large project on the Torrent to Torrent South where we repaired texture coating on four kilometers worth of wall.
Depend on the type of the defects, AFL could perform the following:
- Crack Injection for the small crack less than 0.2 mm
- Resin Injection for the crack from 0.3 mm to 1 mm
- Spalling and Scaling Repairs: A spall may due to the action of the weather, pressure by overstressing, expansion of the surface concrete as a result of corrosion of steel reinforcement or impact damage. Cracks associated with the spalls are usually wide, long, and deep enough to reach the steel reinforcement or prestressing steel.
PASSIVE FIRE PROTECTION
Passive Fire Protection is one of the most important aspects needing to be considered in new building, property, or equipment. Passive Fire Protection is designed to make fires difficult to ignite and difficult to spread through the building.
AFL Services price itself in its ability to be able to apply vermiculite and intumescent to the require film thicknesses. This is proven to be more and more needed to be cosmetic finish due to feature columns and feature steel work inside various location.
