Precast RC manholes are often used in the construction industry to make chambers used for drainage and sewerage systems where maintenance personnel are able to access the facilities underground for maintenance works. Depending upon the specific requirements, precast RC manholes may come with components such as shaft, cover, tapered top, chamber rings, base slab, chamber cover and eccentric rest platform.

Box culverts are used to ensure smooth liquid flow for drainage systems and could be equipped with the dry weather flow (DWF) system and lids.

MKH Building Materials Sdn Bhd provides various sizes of precast RC manholes and box culverts to meet specific requirements for construction projects that meet the standards of the industry.
