Flat Frame

Major features

Because the flat frame has a large hole in the center, the lift pressure acting on the block body is small and it is excellent in stability against falling etc. In addition, by filling this hole with crushed stones etc., it is possible to produce effects matching the river environment.

Applications

Rivers: Foot protection, civil engineering work

Rast Block

Major features
  • 1. This is an economically superior block for which the required quantity in random loading construction is reduced.
  • 2. It has a low center of gravity and excellent stability.
  • 3. It has a shape with one leg of the leg block shortened, it is well engaged with the existing block, it is suitable for the raising work and the leg does not protrude at the time of forming the cross section, so the landscape will not be harmed.
  • 4. Construction is possible even when the raised height (layer thickness) is low.
  • 5. Because the unit price per unit is cheap, it is suitable as a block for waterproof materials.
Applications
