Introduction to the EPDM Construction Process

1. EPDM Installation – Layout and Reference Line Marking To properly schedule the paving workload, baseline surveying is conducted first, followed by the layout of dividing lines according to the established plan. The entire site is then divided into sections, with paving carried out section by section.

EPDM Construction Process Flow

1. EPDM Construction - Surveying and Mapping Bottom Line

To ensure efficient scheduling of paving operations, measurement and layout lines are established according to the predefined plan, dividing the entire site into sections, which are then paved individually.

2. EPDM Construction - Base coating

After the foundation passes inspection, to enhance adhesion between the foundation and the surface layer materials, apply a primer consisting of a specially formulated adhesive mixed with a diluent in a specified ratio. Use a roller brush to evenly coat the surface with the adhesive, and once it has dried, proceed with laying the black granules on the base layer.

3. EPDM Construction - Bottom laying

Using black rubber granules and a special adhesive according to… 6.5: 1 The mixture is blended uniformly in the mixing zone using a stirring device, then transported to the designated marking area by a material‑handling cart, spread with a screed, and compacted with a roller. After the base layer has cured, paving of the surface layer begins. Following two to three hours of curing, the surface is further compacted with a roller; any uneven areas are smoothed with a trowel—such as a float or a textured roller—and can be lightly dampened to achieve a smoother finish.

4. EPDM Construction - Surface paving

EPDM rubber granules and specialized adhesive with 4: 1 The material is weighed and mixed uniformly in the mixing zone using a stirring device, then conveyed to the pre‑marked boundaries by a feeding cart, spread with a screed, and compacted with a roller. Pay close attention to compaction density, surface smoothness, and thickness, and repeat rolling as necessary. After curing for two to three hours, further compact with a roller; any uneven areas should be smoothed with a trowel—such as a float or a textured roller—and can be lightly dampened to achieve a smoother finish.

5. EPDM Construction - Marking and Surveying

Mark the stadium lines according to specifications. After marking, the work must be reviewed by a sports technician. The straight sections shall be rechecked with a calibrated steel tape measure; only after confirming compliance with the standards may the lines be painted in accordance with the prescribed markings.
