Our selection of Techo-Bloc & Nicolock is extensive. Whether you want to build a retaining wall or lay a patio, you are sure to find just the stone you need. You'll also find the drainage fittings and stabilizer sand to get the job done right! Techo-Bloc pavers and wallstone have full color pigmentation throughout the stones, thus ensuring the color will not fade. Additionally, the use of de-icing salt will not damage the structural integrity of Techo-Bloc pavers. Visit our 7,000 sq. ft. Techo-Bloc display and stop in to receive a catalog.
