Types of Manholes We Construct
Sewer System Manholes
Standard Manhole Construction Services for sewage systems include junction manholes connecting multiple pipes, inspection manholes for system monitoring, drop manholes for elevation changes, and terminal manholes at system endpoints. These structures facilitate essential maintenance access.
Stormwater Drainage Manholes
Specialized Manhole Construction Services for stormwater management incorporate catch basin manholes, inlet structures, drainage junction points, and outlet control structures managing surface water flow and preventing flooding.
Utility Access Manholes
Manhole Construction Services extend to utility applications including telecommunications access, electrical cable vaults, water distribution access, and combined utility corridors supporting modern infrastructure needs.
“Design standard: Manholes must be positioned at every pipe junction, change in direction, change in gradient, and at maximum intervals of 90 meters along straight runs.”
Our Construction Process
Site Preparation and Excavation
Professional Manhole Construction Services begin with accurate surveying and marking, safe excavation practices, proper shoring and support, and groundwater management ensuring stable working conditions for quality construction.
Foundation and Base Construction
Critical Manhole Construction Services include compacted base preparation, concrete foundation pouring, proper benching and channeling, and invert formation directing flow smoothly through the structure preventing sediment accumulation.
Wall Construction and Finishing
Quality Manhole Construction Services utilize reinforced concrete rings, brick or block masonry, waterproof rendering, and step iron installation creating durable, accessible structures meeting all safety requirements.
“Safety requirement: Manhole steps must be spaced 300mm apart vertically and positioned 150mm from the wall to provide safe climbing access.”
Materials and Standards
Pro Service Center Services uses premium materials for Manhole Construction Services including high-strength concrete (Grade 25 minimum), engineering bricks or blocks, waterproofing membranes, and corrosion-resistant frames and covers. All materials comply with Kenya Bureau of Standards specifications.
Code Compliance
Our Manhole Construction Services strictly adhere to National Construction Authority requirements, Public Health Act regulations, county government standards, and environmental protection guidelines ensuring all structures pass inspection.
“Durability insight: Using sulphate-resistant cement in manhole construction increases lifespan by 40% in areas with aggressive groundwater conditions.”
