Which type of drainage cover is often used for protection during concrete pours?

The use of a rubber cover during concrete pours is advantageous because it provides durable protection for drainage systems, helping to prevent debris and concrete from entering the drainage lines. This material is flexible, allowing it to conform to various shapes and sizes of drain openings, and it offers a non-slip surface which helps to maintain safety on the job site. Rubber covers are designed to withstand the pressure and weight of poured concrete while effectively shielding the drainage system from potential damage, ensuring that operability and function are preserved after the concrete has cured. The ability of rubber covers to be easily removed after the pour is complete adds to their practicality, allowing for efficient cleanup and restoration of the drainage system.
