Public spaces and bioengineering

Robinia holds use class 4 with the wood alone. What EN 1176 really requires in a playground, and what a specification should say.

Robinia benches, tables, boardwalks and planters: use class 4 without treatment, up to 30 years in the ground, no maintenance, and documents for public tenders.

Fascines, revetments, Krainer walls, retaining walls: why untreated robinia lasts in fresh water, how to drive stakes and which consents to check.
