Case Study: Apartment Pool Deck

Location: Multi-family apartment complex • Problem: Pool deck runoff was causing surface erosion and safety hazards during storms.

Solution: The BG-FILCOTEN® tec 100 system was installed with decorative stainless grates around the pool perimeter. Its self-cleaning interior reduced maintenance, while lightweight handling sped up installation compared to conventional concrete drains.

  • Install Time: 3 days with a two-person crew.
  • Outcome: Pool deck remained slip-resistant and visually clean, even after heavy rains.
  • Owner Quote: “The drainage is both functional and stylish—exactly what we needed for residents’ safety.”

Maintenance Tips

  • Inspect grates quarterly for leaves and debris.
  • Flush channels seasonally to keep hydraulic flow efficient.
  • Check for secure seating of grates and locking mechanisms annually.
