Techo-Bloc vs Unilock

Overall Techo-Bloc vs. Unilock Comparison

Here at Techo-Bloc, we curate textures from around the globe to design hardscaping products that are beautiful on the surface and long-lasting to their core. We also offer the widest variety of styles and colors in each category so you’re sure to find the exact look you need for your project.

  • All of our products are made from precast concrete; while this is common, Techo-Bloc uses our proprietary HD2 technology, which delivers a higher density and higher strength compared to most products in the industry. 
  • We use a finer aggregate selection on the surface of our products, so aesthetically, our products wear and weather more gracefully over time. This means ten years from now, Techo-Bloc products will look just as beautiful as they did when first installed.

We know that many hardscapers are loyal to Unilock and we frequently get questions about how the two brands stack up against each other. While Unilock offers products in almost all of the same categories as Techo-Bloc, their style and color range is often less robust, which can limit your design options. Techo-Bloc has doubled down on precast concrete products; they’re where our passion and R&D investment lies and we feel like we produce the best in the business. 

Another place we differ is our customer service. But don’t take it from us. Syrstone, an installer for Appel Osborne Landscape Architecture, says: “While Unilock’s products are decent, their service is poor. They have different packaging depending on location and I never know if this year's product will be available next year.”

Pavers & Slabs

Techo-Bloc pavers are engineered to handle the freeze/thaw that occurs in the harshest of climates. 

  • We use finer aggregates in our mix designs so there’s more cement to bind the smaller particles together.
  • This results in a product that contains fewer potential voids and, therefore, has a lower absorption rate. 
  • Lower absorption rates translate into a more durable product that resists freeze-thaw and de-icing salts better. 
  • Using finer aggregates also requires an increased percentage of pigment used in the mix. More particles mean more color to coat every little grain of sand and stone and results in a richer and more vibrant color that lasts.

When it comes to styles, both companies offer a large assortment, with Unilock offering 23 styles of pavers and slabs while we offer 48, so you’re sure to find the right look for your project.

Double-Sided Walls

This category is especially important as the versatility of double-sided walls can not be underestimated. These products make the design and construction of seat walls, outdoor living features and raised patios much easier. Plus, double-sided walls reduce waste on-site as two faces of each unit are useable. 

  • Just like Techo-Bloc pavers, our double-sided walls are all interlocking to make installation easier and include our patented anchoring system clips packaged with the product at no charge. 
  • Our walls are made with paver manufacturing machines instead of wall block machines, leading to significantly higher density, better resistance to freeze/thaw conditions and de-icing salt resistance, all of which are covered by a lifetime transferable warranty.

TB2020_shopby-categories_4-Walls.jpg

Both companies offer several collections, with Unilock offering 5 styles and Techo-Bloc offering 10. All of the collections by both Unilock and Techo-Bloc offer multiple colors in each collection, with Unilock averaging 2 different colors per collection and Techo-Bloc averaging 5. 

The biggest difference regarding color between the two manufacturers is not the number offered, but what the colors actually match up to. At Techo-Bloc, every color we make our wall blocks available in is also found in our pavers, slabs, steps, caps and edges. And because they’re manufactured on the same machines, the colors actually do match! This really opens the door to many more design possibilities. Tone-on-tone or high contrast —it’s all possible with Techo-Bloc.

Permeable Pavers

Techo-Bloc’s permeable pavements are designed to allow for the proper percolation of surface water into the ground. This: 

  • Reduces the risk and severity of flooding
  • Eliminates puddles
  • Speeds up the melting process of snow
  • Reduces winter ice hazards
  • Increases cost-savings on de-icing salt and snow removal 


We wanted to ensure we had a wide variety of paver options that were eco-conscious and cost-effective for residential and commercial stormwater management, so we offer 18 different styles. Any design aesthetic is possible with Techo-Bloc.

Unilock, however, offers only 8 styles of permeable pavers, with 7 of those designed to be used for residential use. The limited styles available can restrict the design options for your clients.

Coping & Pool Coping

With over 11 million residential swimming pools across the US and Canada, you need to have a solid offering to present when your client is looking for a stunning poolscape: This means coping is essential. Even if you’re not worried about a pool on your next project, one of the best ways to add value to a hardscape project is through the addition of vertical elements. Caps and coping are the grand finale to complete stairs, walls, fire pits and more. Coping is what takes a job from good to great, but only if you can find that perfect combination of color, texture and style.

Techo-Bloc offers 15 different coping options, 8 of which can be used with pools, and all of which are made from precast concrete. And any of our caps can be used on any of our walls and all are available in all of our colors, offering a wide range of style options.

Unilock offers limited concrete coping options, with one additional natural stone option, that can be used on walls, stairs and fire pits, and one pool coping option, which is only in the bullnose style.

Steps

When it comes to steps, all 5 of Techo-Bloc’s offerings (along with the 2 overlay collections for renovations) are constructed from precast concrete, so you get: 

  • Colors designed to mimic stone’s color variation
  • No potential for irregularities like mineral deposits
  • UV-resistant steps
  • More consistent look from beginning to end
  • Access to the same materials years later, in case you need to replace an individual stone or add to your project

Another huge advantage of our step offering is that it matches perfectly with our paver, slab and wall collections. This makes each Techo-Bloc step unit much more versatile than just a tread.

All of Unilock’s step offerings are made of natural stone which are sourced overseas. This means an increased carbon footprint from shipping over ocean and land. With natural stone, you’ll get natural color variations, both within each stone and from block to block. This gives every project a unique look, but it’s not as durable as precast. Plus, if a stone needs to be replaced down the line, finding the exact same color and pattern can be difficult or impossible.

Edges

Stone borders or edges complement your landscaping and help to reduce maintenance by keeping mulch in -- and the grass out -- of flowerbeds. Adding edges around flower beds also helps separate the pavers on the driveway from the greenery, creating well-defined and stunning, standout spaces that won’t shift from ground movement. 

Since every pavement needs an edge restraint anyway, why not ensure those edges are aesthetically pleasing and bring value to your client? Plus, some of our options, like Avignon and Pietra have an edge restraint anchor built right into the design. It's a 2-in-1 deal!

Our 9 edging stone collections add a polished finish to your outdoor space, with enough style and color options to match or enhance the rest of the home’s look. Unilock does not currently offer any edging products.
