Envirocon recommends drilling and epoxy-anchoring starter bars into the foundation while laying the first course of blocks, rather than casting them in place. This provides crucial accuracy and flexibility during construction.

Here's why:

• Precision is Essential:
  • Interbloc construction requires precise vertical reinforcing bar placement.
  • Casting bars into the foundation offers no room for adjustment if errors occur.
• Account for Concrete Creep:
  • Interbloc blocks will experience creep over the length of the wall as placed.
  • Drilling and epoxying allows for on-site adjustments to compensate for this movement.
  • Installing bars in batches of 15-20 allows for calibration as the wall progresses.
• Managing Larger Diameter Bars:
  • Larger reinforcing bars are even more sensitive to misalignment.
  • Drilling provides the necessary control for accurate placement, especially with larger diameters, where the margin for error is significantly reduced.
• Flexibility for Correction:
  • Drilling and epoxying allows for the correction of errors during installation.
  • Cast in place bars do not allow for correction.
