Why Use Backer Rods?
April 28, 2025
Cracked walls and pavements are a threat to the structural integrity. They are also a sore sight and compromise the structure's visual appeal. Cracks naturally appear on walls and pavements over time. Extreme weather, lack of maintenance, and construction activities nearby all cause cracks to appear. If you are wondering what the solution to this dilemma is, the answer is backer rod. These durable, flexible rods are made of polyethylene foam. Alcot Plastics Ltd. in Guelph, Ontario, manufactures the best PE foam rods. In this blog, we address why you must use backer rods over other solutions to fix cracks.
We Have Been Manufacturing Backer Rods For Decades
Fits Snugly
Backer rods fit snugly within cracks, no matter how big or small. PE foam’s impressive flexibility and shape-retention abilities prove helpful for this. These rods can be squeezed into cracks to fill them without leaving any gaps. Gaps are undesirable as they are counterproductive and leave scope for further damage. Polyethylene foam’s closed-cell structure keeps water and moisture out of the cracks, preventing further deterioration.
Improves Caulk Adhesion
Backer rod gets its name because it serves as a “backing” for caulk. The flexible rods fill most of the cracks from within, reducing the need for caulk. This saves time, costs, and leads to better adhesion. By filling the gap from within, backer rods prevent the sealant from adhering to the bottom of the joint. This accommodates sealant movement due to changing temperatures, prolonging the need for repairs.
Smooth Seal
Aesthetics is crucial! You do not want to seal a gap without focusing on the finishing. Backer rods ensure a smooth seal that blends in with the rest of the structure. The backer rod and caulking combination ensures a seamless seal without compromise on quality.
