Interlocking Block Retaining Walls in Hamilton & Burlington
Segmental retaining walls use engineered concrete units that lock together with a controlled setback. They deliver consistent colour and texture, precise curves, and the ability to use geogrid reinforcement where site loads demand it.

Interlocking Block FAQ
What is a segmental retaining wall?
It is a wall made from engineered concrete units designed to interlock and step back slightly as they rise.
When is geogrid needed?
Geogrid may be required as wall height, soil pressure, slope or loads behind the wall increase. The design determines its length and spacing.
Can the wall match my patio?
Yes. Unilock, Techno-Bloc and Cambridge offer coordinated colours, textures and caps that can complement pavers.
Can block walls curve?
Yes. Many systems are designed for smooth inside and outside curves, making them useful around patios, gardens and entries.
