S.L. Williamson Company has a full repertoire of special roadway projects. We are extremely proud to include in our long list of services, special restoration projects that enhance our rich historical and cultural community. We have worked on historic Key Alley at the University of Virginia’s beloved West Lawn, at the David Rubenstein Visitors Center at Monticello, and at the Wagon Road at James Madison’s Montpelier. These special projects challenge us to replicate the look of the original, while at the same time providing for heavy modern day foot and vehicle traffic and for maintenance and durability issues.

​

We specialize in two unique, fixed surfacing systems called Addaset and Addastone — the Addaset Resin Bound Surfacing System provides a smooth, hard-wearing and low maintenance porous/semi porous surface using a range of natural aggregates; the Addastone Resin Bonded Surfacing System provides an attractive, hard-wearing and low maintenance surface by bonding or fixing loose gravel aggregates to concrete, asphalt, wood or metal. No more slipping on loose gravel!
