Above Ground and Ground Contact Installations


Use the right wood for the right job.


For residential use, there are two classifications of treated lumber, Above Ground and Ground Contact. Viance provides unsurpassed preservative solutions for both types, Ecolife and Severe Weather brands for above ground applications and the Preserve brand for both above ground and ground contact applications.

Ecolife is non-metallic, above ground formulation to help fight the elements such as exposure to rain and the sun’s UV rays. Above Ground is for use in applications that are six inches off the ground, typically used for decking, railing, balusters, decorative posts, trim boards, joists, beams, fence pickets, framing, arbors, and trellises.

Preserve offers specific formulations for above ground or ground contact use for both CA and ACQ preservatives that are designated on the end tags. Preserve formulations are used for specific wood species to attain proper retention levels for long-term performance.

    Preserve ground contact formulations are used for posts, stair stringers, framing, garden boxes, landscape walls, in freshwater, or other situations favorable to deterioration, and for components six inches or less from the ground. It can also be used where lumber may be difficult to maintain, repair or replace and are critical to the to the structure, in areas exposed to ground contact type hazards due to climate, artificial or natural processes or construction, and in areas with poor air circulation. 

    Preserve formulations tagged for above ground use are used in decking, railing, balusters, decorative posts, trim boards, joists, beams, fence pickets, framing, arbors, trellis and other above ground applications.
