When the facility manager of a sports academy in Chennai first called us, she led with a number: 38 degrees Celsius. Not the air temperature — the surface temperature of their existing courts at noon in May. They had a competitor's acrylic surface laid three years ago. It was bubbling near the baseline, sticky in peak summer, and had stress cracks along a seam where the base had been poured in two stages without enough curing time between them.
The academy was expanding — adding a full basketball court alongside their two existing badminton courts — and they wanted all three resurfaced at the same time. The requirement was direct: tournament-grade, heat-stable, no shortcuts. Their players go on to state and national circuits. A surface that bubbles in summer is not just uncomfortable. It affects careers.
The Challenge
The technical problem in Chennai is not just the heat — it is the combination of heat, humidity, and the daily swing between midnight and noon. An acrylic surface that expands under Chennai's midday sun has to contract again at night without pulling away from the base. Poor adhesion between layers, or between the acrylic and the PCC, is what causes the bubbling and delamination that had wrecked the academy's old courts.
The facility manager had done her homework on heat reflectivity before we even met.
Darker colours absorb more solar radiation. On a court where players train four to six hours a day, even a five-degree difference in surface temperature changes the fatigue profile of every athlete on it. She came to the meeting with data.
We recommended Royal Blue for the badminton courts and Dark Green for the basketball court — both with lower solar absorption compared to darker options. Combined with the reflective properties of the acrylic top-coat, we projected a surface temperature reduction of around 4–6°C compared to the old surface.
Scheduling was the second challenge. The academy runs morning and evening batches all year, with only a brief midday window when courts are empty. Shutting everything down for 30 days was not on the table. We proposed a phased court-by-court sequence — the academy would always have at least one working surface during the build.
The Solution
The base specification was non-negotiable: M20-grade PCC, 90mm thick, with a GSB sub-base graded to drain the surface completely within three minutes of rain stopping. In Chennai, a court that holds water for longer than that is unusable for hours after a shower. The basketball court base was poured in a single continuous pour to eliminate the seam failure that had cracked the old surface.
Night curing was a specific call we made for this project. Chennai's daytime heat accelerates curing to the point where the surface becomes porous if overworked while too warm. Our team scheduled all acrylic top-coat layers for application between 9pm and 3am — each coat going down in cooler, more stable conditions before the next layer. This added about four days to the schedule compared to a standard daytime application, but the facility manager agreed it was the right approach.
Most contractors want to finish fast and move on. ChampCourts wanted to finish it right. When they said they would apply the acrylic at night to handle the Chennai heat, I knew we had found the right people for this project.

The Result
The three courts opened on schedule. In the first full season after completion, the facility manager told us that enquiries for training slots had gone up noticeably — partly because the improved courts were now visible on the academy's social media. Within eighteen months, court fees and coaching packages were generating 45% more revenue than the year before the renovation.
The moment the facility manager mentions most often: the academy was selected to host a state-level badminton championship the following year. The selection committee came for a site inspection. The Royal Blue surface — clean lines, consistent bounce — passed without a single comment. In the world of tournament inspections, that is the best possible outcome.
