Waterproof Adhesive Bond
A waterproof adhesive system helps reduce the risk of delamination when the plywood is in contact with moisture.
Plywood for projects where moisture resistance, strength and structural stability matter. Suitable for use in high humidity, changing climates and under intensive loads. Used in construction, transport, packaging, industry and sheltered outdoor structures, where the material has to keep its service properties over a long time.

When to Choose Waterproof Plywood
Waterproof plywood is made for projects where the material works under tougher service conditions. Thanks to the combination of the right wood, the adhesive bond and the sheet's construction, it keeps its strength, stability and service properties even in high humidity.
What Determines the Material's Resistance
A waterproof adhesive system helps reduce the risk of delamination when the plywood is in contact with moisture.
The veneer layers alternate grain direction, so loads are distributed more evenly and the sheet holds its shape better.
Pressing forms a dense bond between the layers and helps produce a stable sheet without voids in the structure.
ALOM checks that the adhesive bond withstands contact with moisture without delamination or loss of the material's properties.

No. Waterproof plywood is designed for humid working conditions, changing humidity and tougher service environments, but it is not a material for permanent immersion in water. Such tasks require separately agreeing the specification, surface type and additional protection.
Yes, with the right specification. For outdoor structures it is important to account for the bonding type, the surface, the loads, the duration of moisture contact and the service conditions.
The main difference is resistance to moisture, delamination and tougher service conditions. This plywood is chosen for tasks where a standard sheet could deform sooner, lose strength or need replacement.
Waterproof plywood is used for construction, transport, containers, packaging, industrial solutions, and outdoor and sheltered structures. The exact plywood variant is selected by thickness, format, grading, surface type and service conditions.
