A stack of PVC pipes of the Drewplast external sewage system, presenting a high-quality product for reliable sewage solutions.

Applications

The Drewplast external sewage system is a modern solution that combines durability, functionality, and environmental care.

The outer and inner layers are made of virgin polyvinyl chloride (PVC), ensuring high resistance to mechanical damage and chemicals. Thanks to the innovative three-layer construction, the pipes perform reliably in all conditions — from residential installations to large industrial projects.

Chemical resistance — ideal for harsh conditions, including industrial environments
Mechanical strength — resistant to damage and deformation during use
Easy installation — lightweight design and a wide selection of fittings ensure short installation time
Durability and reliability — high PVC stability allows trouble-free use for many years
Adequate circumferential stiffness — SN-2 and SN-4 classes withstand soil loads and low-intensity vehicular traffic
Environmentally friendly — middle layer made from recycled material, green energy, and mineral resources reduce the carbon footprint
