Massachusetts & New Hampshire's Unilock Hardscaping Supply
For more than 40 years, Unilock has been manufacturing stone for landscape design. Their EnduraColor™ Plus technology combines nature’s minerals with non-fading color pigments to create ultra-realistic surface textures. Their products include EasyClean™ Stain Resistance and Ultima™ Concrete Technology which has four times the strength of poured concrete.
More and more homeowners are discovering the environmental benefits of permeable pavers. Not only are they durable and aesthetically pleasing, they can play an important role in the management and conservation of rainwater.
A smaller version of the Beacon Hill Smooth, Treo Smooth offers a smooth surface texture for a sleek, modern look with a contemporary color palette.
The dimensional accuracy of Tribeca Cobble gives this product a significant advantage over the imported granite cobble stones that have been used in North America’s streets for centuries.

From traditional shapes and textures to the most advanced technology and unique styles, the choices available in our paver collection are unrivaled in the industry. Whether you're dreaming of an intimate patio, a practical driveway or a luxurious outdoor living space, Unilock has pavers for everyone.
