Silva Cells: Green Infrastructure at Work.

Tree Health and Stormwater Management (SuDS)

Silva Cells contain lightly compacted soil that serves two important functions: growing large trees and treating stormwater on location. The system is designed with sustainability and versatility in mind, with benefits that include:

• Growing mature, healthy urban forests
• LID and SuDS-compliant stormwater treatment
• Simple installation and future maintenance
• Field adjustability

Soil Volume Equals Tree Health

One of the primary obstacles facing urban trees is soil compaction, which is inhospitable for root growth. Silva Cells eliminate this challenge by providing support to the hardscapes above and allowing its void space to be filled with nutrient-rich, uncompacted soil — and the more the better. Research proves that nurturing trees to maturity is best achieved with a robust bank of soil.

Silva Cells and Stormwater (SuDS)

Silva Cells provide at-source stormwater management, treating runoff before it enters the municipal sewer system and local watersheds. This green bioretention solution offers numerous benefits including:

• Pollutant removal
• Peak overflow reduction
• Low-impact development (LID)
• Supplemental tree irrigation
• Adherence to SuDS regulations
