From dyke reinforcement and quays to verandas and playground equipment: below you can see which species is suitable for each application, along with the durability classes and product references. Cloeziana (D70, durability class 1) for heavy-duty applications and salt water; grandis (D50, treated with Tanalith E) for above-ground applications.
Piles, jetties, quays and embankments in fresh and salt water. Cloeziana in service classes 4 and 5, untreated, resistant to shipworm.
Dike reinforcement, revetments, sheet piling and bridges. Strength class D70 according to SHR Wageningen, specified under NEN 5493:2010+C1:2011 and DIN EN 12699.
Verandas, pergolas, carports, fencing and battens in grandis, untreated or treated with Tanalith E. Glulam beams and columns made from cloeziana and grandis.
Playground equipment, observation towers, suspension bridges, vineyard posts and wildlife fencing. Plantation timber with a long lifespan and low maintenance requirements.
Over 65,000 Cloeziana piles in 2025 and 2026 for dyke reinforcement, riverbanks, quays and coastal protection in the Netherlands and Germany: 9,000 piles on the Amsteldijk in Nieuwkoop, 6,850 in Stichtse Vecht, over 10,000 for the Scheldestromen Water Board and 6,000 for Heringsdorf and Süssau. Each of the applications listed below has been implemented somewhere and can be viewed under our projects.
For bank and embankment protection, we supply the complete shoring system: pointed piles and bulkheads made from Eucalyptus cloeziana, from a single source and in a single delivery. Strength class D70, durability class 1 and resistant to shipworm, meaning it can be used at the waterline without the need for preservative treatment.
Sawn timbers and heavy-duty sections in Cloeziana for quays, earth retaining structures and bank protection. Naturally durable and suitable for use in both fresh and salt water without the need for preservative treatment.
Cloeziana performs well in salt water without the need for preservative treatment. The heartwood is resistant to shipworms, as confirmed after 17 years of practical use in the port of Herkingen (SHR report 23.0493, 2024); Cloeziana mooring posts have been in use in the Venice lagoon since 2010. Service classes 4 and 5 in accordance with NEN-EN 335. Applications:
For dyke reinforcement, revetment and sheet piling, we supply round and milled cloeziana piles and sawn timbers, specified in accordance with NEN 5493:2010+C1:2011 in the Netherlands and DIN EN 12699 with DIN EN 1995-1-1 in Germany. Strength class D70 (SHR Wageningen, 2024), taper not exceeding 7 mm per metre. References:
Grandis is straight, light in colour and easy to work with: the ideal species for verandas, pergolas, carports, fencing and battens, either untreated or pressure-impregnated with Tanalith E for use classes 3 and 4. For structural applications, we supply glulam beams and columns made from cloeziana and grandis; CLT is currently under development. Applications:
For public spaces, leisure facilities and the agricultural sector, we supply round posts in cloeziana and grandis: playground equipment, observation towers and suspension bridges, such as the observation tower at Recreatiepark de Leistert and the suspension bridge at the British School, as well as vineyard posts, wildlife fencing and boundary fencing. Plantation timber, FSC®100%, with a long lifespan and low maintenance requirements.
