What TreeBuilders does

TreeBuilders is a Netherlands-based engineering company that designs, manufactures, and distributes the TreeParker underground structural soil cell system, a modular product made from recycled plastic sourced from granulated diapers and processed via injection molding. Founded in 2018 and headquartered in Heeswijk Dinther, North Brabant, the company operates with approximately nine employees and targets a documented urban forestry problem: the average urban tree dies within roughly a decade due to soil compaction, limited root volume, poor water infiltration, and conflicts with underground utilities. The TreeParker system consists of interlocking decks, frames, and posts that form large underground volumes of uncompacted soil beneath paved surfaces while supporting heavy traffic loads. The product integrates ventilation tubes, root-ball anchoring, root-directing panels (to prevent root heave damage to paving), and optional connections to drainage infrastructure for bioretention and stormwater capture (an underground WADI feature).

TreeBuilders' portfolio also includes the Sandwich Construction method, which layers aggregate and concrete over the TreeParker system to create load-bearing pavement above uncompacted soil, and the company maintains a registered TreeParker® trademark. The technical approach is supported by decades of accumulated data on urban tree root growth, soil conditions, and mycorrhiza behavior, with references to scientific studies on the underlying soil science.

The business model is hardware sales through qualified distributors, with direct manufacturer-to-customer contact only where no qualified distributor exists. Pricing is project-specific and not publicly disclosed. The customer base consists primarily of municipal governments and city authorities (Riga, Paris/Eiffel Tower, Madrid/El Retiro Park, Rotterdam, Amsterdam, Brussels, Bahrain/Pearling Path, and multiple Dutch and Belgian municipalities), alongside landscape architecture firms, civil contractors, and project developers. With more than 1,400 documented implementations across at least 14 countries and a multilingual website (English, Dutch, German, French), TreeBuilders has positioned itself as a reference-ability brand in the niche urban green infrastructure market, including flagship projects at three UNESCO World Heritage sites.

Recent moves5 records

Expansion highlights5 records

Regional players

• Nophadrain (Poplast): Nophadrain is a Dutch/European supplier of green roof, drainage, and tree pit systems. Comparable in product category (urban green infrastructure substrates and drainage) but with primary geographic focus in Benelux and DACH rather than TreeBuilders' broader European + Middle East footprint.

Others

• Arup / landscape architecture practices: Arup and similar large engineering/design consultancies are not direct competitors but are key specifiers of structural soil cell systems on major urban projects. They represent the demand-side ecosystem that TreeBuilders sells into alongside competitors like DeepRoot.

Broad incumbents

• Oldcastle Infrastructure: Oldcastle Infrastructure (a CRH company) supplies tree grates, tree guards, and urban landscape drainage products to North American municipal markets. Overlaps with TreeBuilders in the urban tree infrastructure category, but as part of a much larger precast and drainage portfolio.
• ACO GmbH: ACO is a large German drainage and surface-water management company whose tree protection and tree cell products overlap with TreeParker as part of a much wider stormwater and infrastructure portfolio. Comparable as a competitor in the urban drainage/greening intersection, but not a specialist in soil cells.
• Hydro International: Hydro International provides stormwater treatment, SuDS, and green infrastructure solutions that intersect with TreeParker's bioretention functionality. Comparable as a stormwater/green infrastructure peer, though it competes more on water management than on underground tree cells.
• Wavin: Wavin is a major Dutch/European plastic piping and water management company with adjacent urban tree and SuDS solutions. Comparable as a broad incumbent with structural soil and stormwater offerings, but competes through its water management portfolio rather than specialized tree cell technology.

Direct peers

• DeepRoot Green Infrastructure: DeepRoot's Silva Cell system is the most direct competitor to TreeParker: a modular underground structural soil cell used beneath pavements to support urban tree root growth and stormwater management. Both target municipal authorities, landscape architects, and civil contractors on the same type of urban greening project.
• GreenBlue Urban: GreenBlue Urban's RootSpace and ArborRaft systems are structural soil cell solutions aimed at the same urban tree planting market as TreeParker, sold primarily through distributors to municipalities and developers in Europe and North America.
• Citygreen: Citygreen's Stratacell system is a modular structural soil cell used beneath pavements for urban tree planting and stormwater management, directly comparable to TreeParker. Both companies serve municipal and developer customers on streetscape and plaza projects.

Emerging players

• Permavoid plc: Permavoid makes structural plastic sub-base systems for stormwater attenuation and tree pit applications, partially overlapping with TreeParker's combined stormwater + tree function. A smaller, more specialized competitor focused on integrated SuDS + greening.
