The all-round technical cooperation with RINN–a top brick-making company in Germany with 100+ years history, and German environmental brick-manufacturing technology has been used to produce high-quality municipal and garden bricks, to improve the domestic brick-making quality.

Zhongjing owns the completely independent intellectual property rights of permeable bricks and service for ecological circulation. The series of non-braking pressed and room temperature maintained permeable bricks have a permeability of 2.6*10-2cm/s, which meets the requirements of national Level A standard and achieves a perfect balance between the splitting strength and the permeability.

The bricks have compact surface, dense and orderly interior permeable pipeline system, good thawing resistance, good weathering resistance, and 2-3 times longer service life than that of ordinary bricks.
