Our Services
BEPCO designs, engineers and builds post-tensioned concrete structures for all project types — buildings, infrastructure, hydraulic structures and structural rehabilitation.
Thinner floors, longer spans, no beam drops.
Our post-tensioned slabs replace traditional reinforced concrete for car parks, offices, hotels and residences. The savings are measurable from the design stage: less steel, less concrete, less formwork, open floor plates.
Reduced thickness
18-26 cm instead of 23-33 cm in reinforced concrete — 20 to 30% less concrete on every level.
Flat ceilings
No beam drops: complete architectural freedom for partitioning and building services.
Rapid stripping
3 to 5 days versus 21 days in RC. The construction cycle is cut by a factor of four.
Overall savings
20 to 35% saving on structural cost through reduced materials and shorter schedules.
Span 15 to 30 metres with no intermediate support.
Post-tensioning enables large clear spans for halls, atriums and structures where open space matters. Precast or cast-in-place beams, sized precisely for your programme.
15-30 m spans
Clear spans impossible in conventional reinforced concrete, with no intermediate columns.
Optimized cross-sections
Beam depth reduced by 25-35% compared with RC, freeing up usable height.
Fewer columns
More open space and better returns for car parks and commercial areas.
Material savings
30-40% less steel and 15-25% less concrete compared with conventional RC.
Crack-free industrial floors with far fewer joints.
For warehouses, factories and logistics platforms, post-tensioned ground slabs drastically reduce the number of joints, eliminate cracking and extend service life under heavy traffic.
80% less cracking
Permanent compression neutralizes concrete shrinkage and prevents crack formation.
Widely spaced joints (40-60 m)
Instead of 5-6 m in RC, drastically reducing weak points and maintenance.
Superior flatness
FL/FM tolerances maintained over time, even under heavy rolling loads.
Extended service life
25-35% saving on maintenance costs over 20 years compared with conventional slabs.
Watertightness through concrete compression, no membrane.
Circumferential prestressing compresses the concrete against the pressure of the stored fluid. The result: lasting watertightness, minimal maintenance and zero cracking — for drinking water, effluents and industrial products.
Watertightness without membrane
Compressed concrete is intrinsically watertight — no costly PVC membrane to replace.
Service life > 50 years
No waterproofing intervention required throughout the entire life of the structure.
Standards compliance
EN 1992-3 and ACI 350 automatically satisfied by the permanent compression state.
Thinner walls
20-25% less thickness, reducing concrete volumes and foundation loads.
From simple beams to precast segmental decks.
We support designers on every civil engineering structure: prestressed beams, deck slabs, cast-in-place or precast segments, and external prestressing for strengthening.
50-200 m spans
Balanced cantilever or segmental construction for the most ambitious crossings.
Fewer piers
50-70% reduction in deep foundations — the most significant saving.
100+ year service life
Compressed concrete and protected cables for exceptional durability.
Construction without falsework
Cantilever and segmental methods allow building over water or live traffic.
Diagnose, assess and rehabilitate existing structures.
Our engineers get involved early to guide span, thickness and system choices, or to diagnose an existing structure. Bringing in a post-tension specialist saves 15 to 30% of the structural cost.
Comprehensive diagnosis
Visual inspection, non-destructive testing, coring, and code-based analysis in 4 phases.
Post-tensioning expertise
A rare capability in Africa: specialist diagnosis of prestressing cables, anchors, and ducts.
Costed recommendations
Detailed report with prioritized strengthening solutions and budget estimates.
All structure types
Reinforced concrete, prestressed concrete, and composite — buildings, bridges, tanks, and civil engineering structures.
From sketch to handover, a five-step process.
Every project follows the same path, with a dedicated BEPCO project manager and regular reporting.
Study & quote
Drawing review, preliminary sizing and a quote within 48 hours.
Detailed design
Eurocode 2 calculations, execution drawings and material schedules.
Supply
Strands, anchorages, ducts and jacks delivered to site within 72 hours.
Stressing
Carried out by our certified crew, with a stressing record per cable.
Handover & follow-up
Grouting, testing, as-built documentation and a ten-year warranty.
The answers our clients ask for most.
At what project size does post-tensioning become worthwhile?
From around 800 m² of floor or a 25 m span. Below that, conventional reinforced concrete is often more economical. Our engineers tell you honestly during the preliminary study.
Do you work with our design offices and contractors, or as a main contractor?
Both. We work as a separate prestressing package, specialist subcontractor or joint contractor. 85% of our sites are delivered alongside a local main contractor.
What are your mobilisation times on site?
48 hours for a quote, 10 days for execution drawings, 72 hours for material delivery. Our technical team can be mobilised within a week in every country where we operate.
Are the systems and materials you use certified?
Yes. Our strands, anchorages and systems are certified to European standards (ETA, EN 445/447) and compliant with the Eurocodes. We work with the leading global system suppliers.
Do you provide a warranty on post-tension structures?
A ten-year warranty on the works, and a 50-year system warranty on materials under normal exposure conditions. A preventive maintenance plan is provided at handover.
Can you train our in-house teams in post-tensioning?
Yes — we regularly run sessions for design offices, owners and local contractors. One to three days, in French or English, on site or at our offices.
