Timber engineering that strengthens what America already built
Cracked glulam gymnasium beams, under-rated hangars, seismic upgrades on the West Coast, WRD engineers the repair in place with advanced fiber systems, for a fraction of replacement cost and without closing the building.
The USA Problem
Mid-century glulam buildings, turning up under-designed
Across the US, glulam buildings (schools, gymnasiums, hangars, warehouses) are turning up under-designed or cracked, and the default advice is a century-old fix: intrusive steel hardware that robs headroom and caps capacity, or a full teardown. WRD does it the 21st-century way. We laminate high-strength fiber (Kevlar, carbon, and glass) to the existing member to form a true composite, roughly doubling in-situ capacity while the structure stays in service. On the West Coast, changing code is driving a wave of seismic-retrofit work on exactly these structures, and it plays to our strength.

Design methods, in brief
WRD designs restorations with advanced high-strength-fiber systems (FiRP®, RetroShear®, RetroTen®) that bond into a true composite and keep the asset open during the work, and designs new timber too, from engineered bridges to mass-timber buildings. See our full design methods →

Keystone Wye
Two glulam timber highway bridges
Commissioned by Stantec Engineering, WRD assessed both timber bridges of the Keystone Wye Interchange and specified the fix: diffusing decayed elements, epoxy-filling girder-to-deck gaps, and re-staining, adding an estimated 50 years of useful life.
