Functioning expansion joints are the first line of defense to protect the structural foundation of a bridge. Hallmark has replaced numerous expansion joints in the Denver Metro area and knows that preparation of the concrete surfaces and proper placement of the armor are essential to longevity of the joint.

Preparation of the concrete and rebar are essential to ensure a quality, long lasting repair. Hallmark has extensive experience from surface treatments to full depth deck replacement.

Concrete repairs to bridges, dams, spillways, tunnels, water storage tanks, water treatment facilities are typical of projects that Hallmark performs.

Hallmark is experienced in new concrete construction as a subcontractor for construction of concrete features for dams, bridges, highways and other infrastructure projects. 

Hallmark has constructed 8 skateparks on the Front Range including the nationally acclaimed Denver Skatepark that is over an acre of cast-in-place concrete with one bowl that features 3' vertical that drops into a 10' bowl.

Damage to pier caps is not uncommon where the integrity of the expansion joints has been breached.  Hallmark has performed many repairs requiring jacking of girders, as shown, with removal and replacement of portions of pier cap.
