Technical Differentiation
The only HDPE contractor in SA with certificate-grade weld traceability.
Most contractors weld pipe and hope it holds. We use data-logging fusion machines that record temperature, pressure, and cooling time for every joint. Every weld gets a certificate. Every certificate has a serial number. Every project gets a complete weld register.
- Data-logged butt welds with certificate per joint
- CCTV bead cutting verification
- Full weld register supplied per project
- 25mm to 1000mm pipe diameter capability

Why Velocity
We don't subcontract. We don't compromise. We don't miss.
01
Own Equipment, Own Crews
We don't subcontract critical pipeline work. Every HDPE weld, every excavation, every reinstatement is done by Velocity-employed crews on Velocity-owned equipment. Quality control starts and ends with us.
02
Invested In The Tech
Data-logging fusion machines, CCTV bead cutters, NDT testing equipment — we run the latest HDPE welding technology in the country. Because pipeline failures are expensive. Certified welds aren't.
03
22 Years Of No-Fail Record
Since 2003, we've delivered for Egoli Gas, Steyn City, the BRT network, and dozens more. The infrastructure we built two decades ago is still in the ground, still moving gas and water. That's the standard.
Client Feedback
What infrastructure managers say.
They've completed over 50 projects for us across the network. Every weld is certified, every project on time. We give them our biggest jobs because they don't miss.

Operations Manager
Egoli Gas · Pty Ltd
When we built out Steyn City's gas, water, and LPG networks, we needed a contractor who could handle the scale and the standard. Velocity delivered the complete network on schedule.
[NAME TO CONFIRM]
Development Project Manager
Steyn City Properties
HDPE pipeline relocation across BRT corridors is high-stakes work — we couldn't afford failures under bus stations. Velocity's data-logged welds and certified processes gave us the audit trail we needed.

Procurement Questions
Common questions, direct answers.
01
What's your typical project lead time?
Most pipeline projects can start within 4-6 weeks of brief approval, depending on materials availability and site readiness. Emergency or critical infrastructure work can be expedited. Project timelines are issued in writing with every quote.
02
Do you provide warranties on completed work?
All HDPE butt-welded joints carry a 10-year warranty backed by our data-logged certification records. Civil works (paving, retaining, concrete) carry a 12-month workmanship warranty. Manufacturer warranties on materials are passed through to clients.
03
What insurance coverage do you carry?
Public Liability, Contractors All Risk, and SASRIA cover for every project. Workers' compensation (Letter of Good Standing) maintained continuously. Insurance certificates and indemnity letters provided per project. Coverage limits available on request.
04
Is there a minimum project size?
Standard pipeline contracts start at R1M minimum. We accept smaller scopes when bundled with larger works or for existing clients. We don't compete on domestic-scale work — our equipment and team structure is built for industrial and infrastructure-grade projects.
05
Where do you operate?
Our primary operating areas are Gauteng, Free State, and KwaZulu-Natal. We mobilise to other provinces for projects of suitable scale (typically R10M+). All work delivered with Velocity-employed crews — no third-party subcontracting on critical scopes.
06
How do you handle weld traceability and quality control?
Every HDPE butt weld is performed on data-logging fusion machines that record temperature, pressure, and cooling profile per joint. Each weld receives a unique certificate with serial number. CCTV bead-cutting verification on critical joints. Full weld register supplied at project handover.
