parallax background

Kohnen specializes in superior quality precast concrete products.

Precast concrete strengthens with time, while other materials can deteriorate, experience creep and stress relaxation, lose strength and/or deflect over time. The load-carrying capacity of precast concrete is derived from its own structural qualities and does not rely on the strength or quality of the surrounding backfill materials. Precast concrete products can provide a service life in excess of 100 years.
