The Challenge
Jaya One, a mixed-use development in Petaling Jaya, required urgent surface preparation for waterproofing its driveway. The surface was uneven, making it unsuitable for direct application of a waterproofing membrane. Without proper levelling, the waterproofing layer risked poor adhesion, reduced durability, and future water ingress.
With over 1,800m² of floor area surrounded by busy restaurants and cafes, the project demanded a quick turnaround with minimal disruption to daily operations.
Our Approach & Result
We carried out high-precision surface preparation for waterproofing using SGi Tech’s Parana Milling machine. The surface was milled at a 5mm depth across the full 1,800m² area. This process removed the top layer cleanly and evenly, creating an ideal surface profile for the waterproofing system to bond effectively. The project was completed in less than 2 weeks, ahead of schedule and without causing major disruption to tenants or visitors.

When a surface needs to be waterproofed, proper preparation is essential to ensure the coating performs well and lasts. Jaya One’s driveway required a clean, level profile ready for waterproofing application.
We used SGi Tech’s Parana Milling to mill the over 1,800m² surface at a depth of 5mm, removing imperfections and creating the right serrated texture for optimal bonding. The method allowed us to finish the project in under 2 weeks while keeping the surrounding areas clean and operational.
With the surface now precisely profiled, the site was ready for the next phase of applying a waterproofing layer that will protect the structure and extend its service life.
