When you are considering how to increase the strength of existing structural members, jacketing is a technique that you should consider.
Jacketing is a process that involves placing steel plates on both sides of the member to be strengthened and welding them together. This process can help strengthen your structure so it can withstand more load without buckling or shearing.
In this blog post,we will discuss how jacketing works,what type of structural members are best suited for this process,why it’s important to have an experienced professional do the work,and much more.
The Jacketing Process Jacketing can be used to repair deteriorated columns, piers, and piles.This is particularly useful for treating deteriorated concrete or steel sheet pile bulkheads where protecting nearby structures are not available.
Jacketing of the sheeted area with a thick water impermeable geotextile membrane containing within an asphalt grout mixture and is carried out by lowering a template into place and then injecting grout material through the geotextile membrane.
The technique is called Jacketing because the primary reinforcement, steel sheet piles, remain in a vertical position under a jacket of a geomembrane while being injected with asphalt concrete.This has been successfully used to restore sheet pile bulkheads for piers, bridges, and other structures.
Jacketing of columns should be carried out when the foundation type is either temporary or permanent.Temporary foundations are typically found in construction applications where the soil-supported structure is not capable of carrying vertical loads but should be capable of carrying these loads when a permanent foundation is completed.Jacketing of the columns should not be used where the soil-supported structure has a foundation with vertical piles capable of supporting heavy load capacities and is best performed when there is only one column that requires restoration and should not be used for structures with multiple deteriorated columns.

How to identify the different types of column jackets.
A column is a solid cylindrical structural element that supports a structure above it, such as a building.Columns consist of three parts: the foundation, the architectural section, and the capital.
Jacketing refers to placing an outer layer of material around a column.It can be used for many different reasons depending on the application and the overall design.Jacketing is often chosen for its unique aesthetic properties, but can also be chosen for insulation purposes in colder climates.It typically occurs during the initial construction or when undergoing an addition to a structure in order to match existing columns in the area.
The three types of column jackets are metal, wood, and concrete with different purposes in mind.
Metal Jacketing is composed of galvanized or stainless steel. It can either be wrapped around an existing column, or it can be welded to the surface of a new column. It provides weather protection for columns and helps with insulation,giving off more heat than wood or concrete.
The metal Jacketing will also provide corrosion protection if it is made of stainless steel.
Wood Jacketing is used to imitate the color and texture of masonry, making it a popular choice for historic restorations. It is formed by attaching boards over the vertical structural supports using nails or bolts
Concrete Jacketing is typically used for aesthetic purposes and functions as a permanent component in a building. Concrete Jacketing can be done by attaching boards or planks to the exterior of an existing column, or through pouring concrete directly onto an existing structure.
Concrete Jacketing provides insulation against temperature changes and acts as a noise barrier, blocking out sounds from outside the structure.Concrete Jacketing also provides protection against corrosion and water damage.
Tips on how to install your column jacket
To instal column jacket follow below steps
1. Apply a coat of paint (using spray cans) to the exposed concrete and surface area around the column base.
2. Remove any dangerous objects such as spikes or nails from your foot path or driveway that could penetrate your new covering.
3. Before you begin to install your column jacket, ensure to use rubber gloves and eye protection as this will prevent any splinters and other dangerous objects.
4. Mark out areas of your column jacket to determine how big you would like them before cutting them out with a power saw or jigsaw. Use a pencil for marking and take note of notches on corners for additional strength around the exposed column is recommended.
5. Using a grinder with a 60-100 grit wheel, remove the exposed portion of the columns core until it is exposed to roughly ½” – ¾” (12mm – 19mm) so that it fits snugly inside the core of the column jacket. This will allow easy installation of Column Jacket around the column.
6. Using a power drill, install any additional concrete anchors that come with your Column Jacket kit into your concrete to allow more strength for installation of Column Jacket on top, if required.
7. Ensure you have adhesive on hand to stick down your Column Jacket before you proceed to the next step. Column Jacket kits come in self-adhesive forms; however, if you require stronger adhesion you can purchase glue at hardware stores
8. Apply adhesive to both sides of Column Jacket if needed before installing them around your exposed column.
9. You should now have all Column Jackets installed around your exposed Column. Ensure that Column Jackets are fitted securely and tighten the bolts using a socket wrench where necessary. Column Jacket kits come with security fasteners to ensure Column Jacket remains in place around Column.
10. Now you can begin installing Column Jacket caps, Column Sleeves or Column Wraps onto the tops of Column Jackets to finish off your Column Protection Column Jacket kit.
11. It is recommended that Column Jackets are installed every 2-3 feet around Columns to provide maximum protection, however this is dependant on the size of your Column Jacket kits – Column Jacket packs come in different sizes with most being suitable for most Column sizes.
