Pressure-Balanced Hydraulics. Zero-Leak Reliability Across Every Floor.
Complete building plumbing networks, acoustic wastewater drainage, multi-stage pressure booster skids, and precision sanitary ware installations engineered for apartments, commercial towers, healthcare facilities, and private residences.
Plumbing issues in multi-story buildings and homes cause extensive interior damage when corners are cut. From basement water reservoirs and variable-frequency booster systems to top-floor penthouses, our hydraulic team eliminates water hammer, prevents acoustic drain transmission, and guarantees 100% leak-free integrity through 12-bar pressure certification and laser-graded drainage slopes across Addis Ababa.
24-hour certified pressure test hold ensuring zero micro-leaks in all walls and slabs.
VFD automated inverter multi-pump skids ensuring consistent water pressure across all floors.
Mineral-reinforced acoustic uPVC soil and waste stacks eliminating flush noise in living spaces.
Dual-check valve contamination barriers isolating municipal water from building reserves.
Laser-aligned pipe gradient control verified by high-definition crawler camera inspection.
Core Plumbing & Sanitary Deliverables
Pressurized Potable Water Reticulation
Clean, hygienic hot and cold water distribution throughout buildings and homes. We use virgin-grade PPR-C fusion-welded piping with dedicated floor isolation valves, eliminating concealed joints and preventing water damage.
Acoustic Soil, Waste & Vent (SWV) Stacks
Engineered gravity drainage networks that silently convey sanitary discharge without odor leakage or gurgling. Designed with generous inspection cleanouts, acoustic vibration-dampening brackets, and proper roof vents.
Basement Booster Skids & Sump Stations
Complete building water management: basement storage reservoirs, automated variable frequency booster skids, rooftop buffer tanks, and heavy-duty submersible sump pumps for basement drainage.
Sanitary Ware & Architectural Fixture Fit-Out
Precision installation of high-end bathroom and kitchen sanitaryware: concealed in-wall cisterns, wall-hung toilets, thermostatic rain showers, sensor faucets, and handicap-accessible fixtures.
5-Phase Building Plumbing Protocol
Hydraulic Demand & Pressure Zone Sizing
Calculation of peak water fixture units (FU), sizing of main risers, and planning pressure zones to guarantee uniform water flow from ground floor to penthouse.
Sub-Slab & Underground Drainage Rough-In
Laser-guided trenching and bed preparation for underground sanitary lines, cast-in sleeve placements in foundation beams, and pre-pour inspection.
Vertical Supply Risers & Acoustic Stacks
Erection of vertical water supply risers, sound-dampened acoustic drain stacks, and horizontal distribution runs within ceiling plenums and drywall shafts.
Booster Plant Room & Reservoir Plumbing
Installation of booster pump skids, float switches, pressure tanks, water filtration stages, and interconnecting manifold valving in mechanical rooms.
Sanitary Fixture Trim-Out & Drain CCTV Verification
Setting and sealing of porcelain ware, faucets, shower valves, followed by a full CCTV camera crawler survey of all main sewer branches to guarantee zero blockages.
