Elastic concrete joints are formed with polyurethane materials of two ingredients 

and special aggregate. 

These joints can be used immediately just through mixing the main material, hardener 

and aggregate at the construction site, and they have a waterproof function with 

adhesion with regard to strong concrete. 

In addition, elastic concrete is used as fillers of expansion joints to absorb impulsive loads of vehicles, and equally conveys and distributes loads to lower structures.

Elastic concrete which is highly ozone-resistant, chemical-resistant and abrasion-resistant 

is a material which is easy to work with.

 Features

-During the rainy season, elastic concrete can induce drainage of water 

  penetrating into the pavement layer, minimizing concrete damage. 

-The elastic material which possesses elasticity and semi-rigidity is highly 

  durable. 

-Elastic concrete has excellent adhesive power with the existing pavement 

 layer and concrete. 

-There is almost no plastic deformation. 

-Trafficability is good because continuity with the existing pavement layer 

  is maintained. 

-Workability is excellent even with steep end gradients. 

-The elastic material is cured quickly, and traffic is opened fast.

  (within 2 hours)

-When the material is used, construction becomes simple, and maintenance 

  and repair become easy.

 Preparation

Elastic concrete shall be applied for parts from which pollutants, such as dust 

and oil are removed. 

The ordinary Portland cement concrete shall be generally applied after being cured for over 14 days. 

The planes and the side faces for installation shall be chipped and grinded to

become straight. 

After sand blasting, pollutants shall be removed cleanly before construction.
