Granby Hospital

Project: Emergency Vehicle Entrance – Granby Hospital

Product Used: Polydrain 2512
Type: Precast polymer concrete trench drain with 0.6% built-in slope
Grate: Ductile iron grate with black polymer coating, compliant with ASTM A536 Grade 80-55-06
Frame: Model 2510, independently anchored to the concrete slab
Load Rating: 620 PSI (per AASHTO M-306)
Load Class: E (up to 60 tons – heavy-duty applications)
Open Area: 0.21 ft² per linear foot [0.064 m²/m]

Application:

Drainage system installed at the emergency vehicle access area. Designed to efficiently capture runoff while supporting frequent heavy vehicle traffic, such as ambulances and fire trucks.

Technical Advantage:

Unlike competing systems where the frame is cast into and supported solely by the drain body, the Polydrain 2512 features a frame independently anchored into the concrete slab. This design allows for even load distribution across the encasement slab, improving long-term durability and structural performance under dynamic stress.

Advantages:

• Increased resistance to crushing and frame displacement

• Structural frame integrity maintained independently of the drain channel

• Efficient load transfer to surrounding slab

• Lockable system for added safety and ease of maintenance
