Steam curing uses controlled heat and moisture to accelerate hydration. UNIK‘s delivered systems, including the 30-pocket finger car curing system for a Sri Lanka project (2025), achieve target strength within 10 hours.
Moist curing involves covering pavers with wet burlap or plastic sheeting, or applying periodic water spraying. This method is suitable for smaller production volumes or sites without steam equipment.
Membrane curing applies a liquid curing compound that forms a moisture-retaining film. This method is effective for large surface areas but requires careful compound selection to avoid surface discoloration.
UNIK‘s paver block production lines combine mould design with curing system recommendations. The complete wave-type paver production line delivered to Sri Lanka (2025) included a colour-face material feeder for two-tone pavers, an automatic stacker and film wrapper, a 30-pocket finger car curing system achieving strength within 10 hours, and an on-line remote-assist camera for technical support.
Several common curing challenges have identified solutions. When low strength appears after curing, the solution is to extend curing duration or verify temperature and humidity conditions. For surface cracking, reducing the initial drying rate through fogging or plastic covering is effective. Color inconsistency requires uniform moisture control and avoiding over-spraying of curing compound. Efflorescence, or white deposits on the surface, can be reduced by lowering soluble salts in the mix and improving curing uniformity.
