About Blumer Lehmann
Blumer Lehmann is a Swiss group of companies in the timber industry and timber construction with headquarters at the Erlenhof in Gossau SG. The company processes Swiss round timber from sustainable regional forestry into sawn timber, planed products, facades, glulam and cross-laminated timber products (CLT-curved, CLT-clever, CLT-solid, PLT-solid); residual wood is further processed into pellets, wood chips and sawdust. In timber construction, Blumer Lehmann realizes element buildings, load-bearing structures, free-form structures, timber modular buildings and timber-clay buildings, as well as silo and plant engineering for de-icing material storage, wood silos and salt storage halls including brine, conveying, control and measurement technology. In addition, architecture, project development, general contracting, BIM planning and parametric planning are offered. With more than 600 employees, the group operates at sites in Switzerland, Germany and Luxembourg and realizes projects worldwide.

Materials and Processes
Swiss round timber / sawn timber
Locally renewable raw material from sustainable regional forestry, the basis for solid and glued timber products.
Glulam and CLT
Glued timber products such as glulam, Duo frame timber, CLT-curved, CLT-clever, CLT-solid and PLT-solid for load-bearing structures and modular construction.
Clay (timber-clay construction)
Material for sustainable building with clay and wood.
Glass-fibre reinforced plastic (GRP)
For glass-fibre silos in small sizes from 50 to 200 m³, mainly for the storage of rock salt.
Plastic tanks
Brine tank systems with fill volumes of up to 250 m³ for salt solutions such as NaCl, CaCl or MgCl.
