Marine Structures
Benefits:
- Increased durability
- Protect against water ingress and salt water corrosion
- Ultimate corrosion protection in the splash zone
- Reduced life cycle costs
- Protects against corrosion; increased durability means a longer structural life
- Stays inside the concrete, no need to reapply
- Green construction
- Longer-lasting structures are more sustainable – reduce the environmental cost of repairs and replacement
- Concrete with Hycrete admixtures can easily be recycled – Hycrete admixtures are Cradle-to-Cradle™ Certified
- Safe
- NSF/ANSI 61 certified
Marine structures such as sea walls, piers, and waterside buildings are under extreme pressure from the environment. In the splash zone, they are subject to thousands of waves per day, and related wetting and drying cycles with salt water. The corrosive salts are absorbed into the concrete and corrode the reinforcing steel, causing rusting and spalling, and shortening the life of the structure. There are a number of traditional protection systems. Coated reinforcing steel, including epoxy-coated rebar and galvanized reinforcing steel, protects the reinforcing steel but may be vulnerable where there are scratches and other damage from transportation and installation. Integral corrosion inhibitors such as calcium nitrite (Grace DCI®, BASF Rheocrete®, etc) directly protect against rusting. Permeability reducers such as high-performance concrete and crystalline waterproofing admixtures reduce the amount of water and corrosive salts that can enter the concrete but do not protect the steel itself. Each of these solutions either reduces water and salt penetration or directly protects rebar against corrosion. Hycrete solutions do both.
With Hycrete X1000, permeability is reduced, with water absorption at less than 1%. This compares with 3-5% for regular concrete. The reinforcing steel is also protected by a passivating layer, coating the steel and protecting it from chloride corrosion. Hycrete X1000 helps heal small cracks, reducing the risk of penetration. It is normal for concrete to crack somewhat due to shrinkage, and Hycrete X1000 inhibits corrosion in slightly cracked concrete better than high-performance concrete or calcium nitrite corrosion inhibitors.

With all these properties in one material, Hycrete X1000 is a superior corrosion inhibition solution for marine structures. It can be used on its own, or for double protection it can be used in combination with coated rebar, non-cementitious materials, or coatings to give belt-and-suspender corrosion inhibition.

Hycrete products for marine structures:
Hycrete X1000 can help protect against corrosion in aggressive marine environments.
Pier in Maine, with Hycrete corrosion protection. In the splash zone, salt water is constantly sucked in to the concrete. Hycrete X1000 protects against both water ingress and pier corrosion.
Sea walls like this one in Hawaii corrode and fall apart quickly because of salt damage. For this sea wall, Hycrete is working with the US Army Corps of Engineers to create a more durable replacement.
