Drainage chambers DN315
for the construction of external drainage systems
Chambers (manholes) are used in green areas not loaded with more than 500 kg with the use of a PE cover or more according to PN-EN 124 with the use of a cast iron frame and a concrete ring.
Most often it is the construction of single-family houses (e.g. drainage around buildings), recreational and sports areas, gardens and drainage of excavations.
Drainage chambers are used as inspection and cleaning chambers for flushing clogged drainage systems with deposited soil, and as a sedimentation basin.
