Concrete Drainage Block
PBM Concrete Drainage Block (LK series) is a precast concrete masonry system designed for the construction of open surface drainage channels — commonly known as longkang — across Malaysian residential, commercial, infrastructure, and landscape projects. The series comprises four modules, varied in profile and dimension to suit standard channel construction, deeper channels, and specialised inlet or transition geometries.
Applications
- Roadside surface drainage channels (longkang)
- Compound and perimeter drainage around residential and commercial properties
- Stormwater drainage channels in townships and developments
- Industrial and warehouse drainage
Key Features
- Four module variants covering standard channel construction, deeper channel sections, and specialised profile geometries
- Standard 390 × 190mm face dimension on most products coordinates with the wider PBM CMU dimensional system for combined construction
- Hollow-cavity design supports reinforcement bar and concrete fill where structural drainage walls require additional load capacity
