Block Wall Construction Process:


Why does Triad use Techo-Bloc wall blocks?

  • Transferable lifetime warranty – Techo-Bloc Warranty (PDF)
  • Techo- Bloc wall blocks are manufactured with color through-and-through
  • Less breakage, so you don’t have to sort through pallets and discard broken wall blocks
  • Techo-Bloc pavers, curbstones and wall stones are designed specifically to complement each other; your patio can match the wall and the wall can match the walkway and steps.

“Your precious stones are the benchmark for quality” – Techo-Bloc
