Techo Bloc Champlain Grey is a mid-grey blend in the Blu 60 slab range, sold in Smooth and the denser HD² Smooth finish. It sits between the pale Greyed Nickel and the darker Onyx Black, with matching caps, walls and driveway pavers. Not every size comes in every color, which trips people up.
I went through the Blu 60, Blu Grande and Raffinato spec sheets and Techo-Bloc's warranty, so every availability claim below is the manufacturer's.
Blu 60 colors and finishes, size by size
Blu 60 is a 2⅜-inch (60 mm) pedestrian slab. Its modular set is 6½ x 13, 13 x 13 and 19½ x 13 inches, plus a single 6 x 13 unit and the 32½ x 19½ inch Blu Grande. According to Techo-Bloc's Blu 60 Smooth spec sheet, a modular pallet covers 116.82 sq ft and weighs about 3,170 lb in Smooth or 3,295 lb in HD² Smooth.
| Color | Modular set | 6 x 13 | Blu Grande |
|---|---|---|---|
| Champlain Grey | Smooth, HD² | Smooth, HD² | Smooth, HD² |
| Shale Grey | Smooth, HD² | Smooth, HD² | Smooth, HD² |
| Greyed Nickel | Smooth, HD² | Smooth, HD² | Smooth, HD² |
| Onyx Black | Smooth, HD² | Smooth, HD² | Smooth only |
| Chestnut Brown | Smooth, HD² | Smooth, HD² | Smooth, HD² |
| Beige Cream | Smooth only | Smooth, HD² | Smooth only |
| Chocolate Brown | Not listed | Smooth only | Not listed |
| Caffè Crema | HD² only | HD² only | HD² only |
Techo Bloc Champlain Grey is one of only four colors offered in both finishes across all three formats, so you can mix sizes freely. All share a 9/32-inch (7 mm) joint.
Champlain Grey vs Shale Grey vs Greyed Nickel
Three of the eight colors are greys, which tells you roughly which decade we're in.
- Greyed Nickel is the lightest, suited to white siding.
- Shale Grey is a light-to-mid grey with pale mottling.
- Champlain Grey is the mid-grey with brown and charcoal tones. That warmth lets it sit next to tan brick and cedar, where a cool grey can look slightly blue.
Each color "is composed of a variety of darker & lighter tones", per the warranty, so one sample slab shows one corner of the range.
For a driveway, Champlain Grey comes on the 80 mm Blu 80 Slate paver, the thicker version made for vehicle loads.
The warm side: Chestnut Brown, Beige Cream and Caffè Crema
Grey isn't compulsory, whatever recent patio photos suggest. Chestnut Brown suits red brick, and Caffè Crema is pitched in Techo-Bloc's color launch release as a hue that "warms up contemporary landscapes from the cold greys." If Champlain Grey looks too cool against beige stucco, compare it with Caffè Crema.
Dark colors: heat and white bloom
Onyx Black and Chocolate Brown make the sharpest borders, but the Blu 80 sheet warns that "dark-colored paving units could get very hot under the sun," and the warranty says efflorescence is "more perceivable in darker colors" and not covered. A 12-inch Onyx Black band around a Champlain Grey field gives you the crisp edge without making the whole patio a hotplate.
Matching Champlain Grey walls, caps and steps
- Raffinato wall and step: no Champlain Grey.
- Raffinato cap (14 x 28 in, Smooth): includes Champlain Grey, so the cap can match the patio even when the wall can't.
- Mini-Creta Architectural, Semma, Villagio, Techo Bloc Eva and the Valencia fire pit: all list Champlain Grey.
For the smooth Raffinato look, the usual move is a Greyed Nickel or Onyx Black wall with a Champlain Grey cap. Our guide to Techo-Bloc walls compares those systems, and our paver colors guide covers pairing pavers with siding.
Choose Champlain Grey at the dealer yard, not from a screen
My one strong opinion here: never order a Techo-Bloc color from a photo, a swatch card or this page. The warranty excludes "color matching to printed representations" and says "final color selection should be made at your local dealer from stocked product." Look at full pallets in daylight and lay from at least two pallets at once.
Take a couple of loose slabs home and put them where the patio will go. Morning light and evening light will give you different answers. Go with the evening one, because that's when you'll actually be sitting out there.
FAQ
Is Techo Bloc Champlain Grey a warm or cool grey?
It reads as a warm-leaning mid-grey, mixing grey with brown and charcoal tones, which is why it suits brick and timber.
Can I use Champlain Grey on a driveway?
Not as Blu 60, which is a pedestrian slab. Use the 80 mm Blu 80 Slate paver, which comes in Champlain Grey.
Which Blu 60 color hides dirt and efflorescence best?
The mid-tone blends, Champlain Grey and Shale Grey. Efflorescence shows most on Onyx Black and Chocolate Brown.
