How it Works


Masterblock is a patented ‘complete’, tongue and groove building system. Each block weighs approximately 220lbs and measures 32” long x 12” high X 11” deep*. (*7” concrete x 4” ASTM approved foam)

The block has a finished exterior and a drywall ready interior.

Specialized blocks for lintels, corners and off cuts are also available.


Chose the installation option that is best for you!

  • Purchase and install Masterblock yourself, or with the help of a contractor.

The Process

1. Design

2. The Building Process

  • Prepare your building site;
  • Form and lay the foundation as per code and rough out plumbing;
  • Carry on… or leave the rest to us!
  • Drill holes every 16” into the foundation and place a patented StrongBloc epoxy capsule in each one;
  • Reinforce structure with rebar horizontally every 12”;
  • Frame windows and doors to plans;
  • Once the walls are to roof height insert vertical rebar into pre-drilled holes at 16” intervals to release epoxy;
  • Back-fill the block cavities with patented Masterblock high-strength epoxy grout;
  • Install the double pressure treated top-plate.
