Sealing Systems

Corkjoint is a specialist in the development and supply of Sealing Systems

Sealing systems for concrete structures are used to prevent the intrusion of water, air, and other substances into the structure, which can cause damage and reduce the lifespan of the concrete.

CORKJOINT offers a range of Sealing Systems for use that are specially designed to counter environmental factors and offer strong sealing and bonding.

There are several types of sealing systems used in concrete structures, including;

  • Joint sealants: These are used to fill the gaps between different sections of the concrete structure, such as expansion joints or control joints. Joint sealants can be made from various materials, including silicone, polyurethane, and polysulfide.
  • Waterproofing membranes: These are used to prevent water from penetrating the concrete structure. Waterproofing membranes can be applied to the surface of the concrete or integrated into the concrete mix itself. Examples of waterproofing membranes include bituminous membranes, PVC membranes, and liquid-applied membranes.
  • Coatings: Coatings are applied to the surface of the concrete structure to provide protection against water, chemicals, and other elements. Coatings can be made from various materials, including epoxy, polyurethane, and acrylic.

The Sealing System, depending application, may need to be able to withstand continuous water exposure, UV and atmospheric exposure, electrical conductivity or other environmental factors, while providing long-term durability, integrity and robustness.

Sealing systems are needed in a wide variety of applications where concrete structures are exposed to the elements, chemicals, and other substances that can cause damage or deterioration. 

Here are some examples of where sealing systems may be used:

  • Building construction: In commercial, residential, and industrial buildings, sealing systems are used to protect concrete floors, walls, and roofs from water intrusion, chemical spills, and other types of damage.
  • Infrastructure projects: Sealing systems are often used in infrastructure projects, such as bridges, tunnels, and roads, to protect the concrete from weathering, corrosion, and other forms of deterioration.
  • Water containment structures: Sealing systems are critical in structures designed to contain water, such as swimming pools, water tanks, and dams. Without effective sealing, water can leak out of the structure or penetrate into the concrete, causing damage and reducing the lifespan of the structure.
  • Industrial facilities: In industrial facilities, sealing systems may be used to protect the concrete from chemical spills, abrasion, and other types of damage caused by industrial processes.
  • Parking structures: Sealing systems are often used in parking structures to protect the concrete from water and salt intrusion, which can cause cracking and other types of damage.
  • Decorative concrete: Sealing systems are used to protect decorative concrete surfaces, such as stamped concrete or stained concrete, from water and other types of damage.

Overall, sealing systems are essential for protecting concrete structures from damage and ensuring their long-term durability. The specific sealing system used will depend on the particular application and environmental conditions of the structure.
