Interlocking Blocks Moulds Kenya
Supporting Urban Development with Local Delivery and On-Site Training
Sri Lanka's construction sector is undergoing rapid transformation. Colombo, Kandy, and Galle are modernizing their infrastructure, while major developments like the Colombo Port City project demand high-quality paving solutions. Interlocking paving blocks have become the preferred choice for roads, plazas, and residential areas-offering durability, visual appeal, and faster installation than traditional poured concrete.
UNIK has been actively serving the Sri Lankan market. In June 2025, the company delivered a complete fully-automatic hydraulic wave-type interlock paving block production line to a major waterfront development in Colombo. This page covers the mould specifications, local support, and applications available to Sri Lankan contractors and block manufacturers.
UNIK's 2025 Delivery to Colombo: A Case Study
In June 2025, UNIK announced the delivery of a complete production line to a waterfront development project in Colombo, Sri Lanka. The equipment was designed specifically for high-precision wave-pattern plaza and marina pavers, engineered for Sri Lanka's tropical climate and high-strength concrete mixes.
The line features UNIK's latest Interlock Paving Block Moulds, capable of producing 200×100×80 mm wave-type pavers at 18 cycles per hour-enough to surface 2,000 square meters per shift.
Key Performance Features
Rigid Cast-Welded Frame – Heavy-duty cast-steel columns combined with robot-welded beams absorb vibration, ensuring over 50,000 hours of frame life.
PLC + HMI Intelligence – A Siemens S7-1200 PLC with I/O modules handles safety interlocks, fault diagnosis, and recipe storage. Operators simply select the product code from the touchscreen.
Proportional Hydraulics – Rexroth proportional valves adjust flow and pressure in real time, guaranteeing identical compaction on every cycle.
Mechatronic Integration – Synchronized hydraulic, electrical, and mechanical movements deliver a rejection rate below 1% and uniform density across the paver surface.
Pneumatic Anti-Vibration Mounts – These cut noise to below 72 dB and protect nearby structures from resonance, which is critical for urban plaza locations.
Quick-Change Mould System – A side-clamp design allows one operator to swap Interlock Paving Block Moulds in under 15 minutes, supporting multi-shape production with the same machine.
Local Support and Training in Colombo
A UNIK technician arrived in Colombo to supervise mechanical and hydraulic commissioning, calibrate the Interlock Paving Block Moulds, and train local staff on operation, maintenance, and mould change-over procedures.
According to the client's project director: "We chose UNIK because they offered a turn-key solution-from mould design to curing automation-and their moulds already exceed 80,000 cycles on similar projects in the Maldives."
