Features
Bridge deck fatigue caused by dynamic loading catalyzes the cracks on the top surface. D-Fend I penetrates the concrete surface to fill in any pores or micro cracks, creating a seal that will help to prevent further damage.
Its intrinsic strength and tensile strength not only render the concrete waterproof but also increase its toughness, allowing it to withstand long-term fatigue arising from dynamic loads on the structure
D-Fend I is a unique waterproofing system that uses an impregnation and coating combination to provide waterproof protection. This product is a low viscosity (2-5 cps), high tensile, and compressive thermoset polymer, designed specifically for bridge deck structures.
Principle Advantages
- The D-Fend I have an extremely low viscosity, which allows it to penetrate deep into the pores of the concrete. This impregnation action also makes them almost inseparable from the concrete, resulting in a very durable seal.
- This product can permeate through even the smallest of cracks, at 0.025mm. It strengthens the concrete matrix by improving the binding between the cement and aggregates.
- It renders the surface of the concrete waterproof.
- It has high elasticity that provides sufficient flexibility to withstand cyclic loading. And has a great crack bridging ability as well.
- When used on top of a deck, its high compressive strength and elasticity work together to effectively prevent cracks from forming.
