WHY USE IT?

In order to ensure fabricated rebar cages are properly positioned for concrete placement every time. The ShaftSpacer aligns and centers rebar cages within the drilled shaft — providing proper clearance between the rebar cage reinforcement and the interior side walls of the shaft or casing.

SHAFTSPACER

A guide and alignment system for lateral positioning of reinforcement cage within caissons, drilled shafts and other geotechnical construction applications.

APPLICATIONS

  • Bridge Foundations
  • Building Foundations
  • Retaining Wall Foundations
  • Street Light Foundations
  • High Mast Foundations
  • Transmission Line Foundations
  • Sub-station Foundations
  • Tower Foundations
  • Slurry Walls

ADVANTAGES

  • Saves time & money on site
  • Easy to install
  • Lightweight, yet strong, durable
  • Engineered with the contractor in mind
  • Made of high-density plastic, resistant to corrosion, and chemicals common to construction
  • Excellent guide system for placement of fabricated rebar cages into drilled or excavated shafts • Economical with minimal installation costs
  • Indefinite shelf-life and easily stored

CONSTRUCTION BENEFITS

  • Ensures the bar reinforcement is properly spaced and aligned within the confines of the drilled shaft or excavation.
  • Provides quality assurance of the sub-contractor’s performance for the contractor and owner.
  • Provides quality assurance of the contractor’s performance for the engineer and owner.
  • Installs quickly and easily, requiring only unskilled labor.
  • Increases job profitability because skilled labor is released for more demanding tasks.

SHAFTSPACER MINIMUM PLACEMENT RECOMMENDATIONS

  • Use one ShaftSpacer per foot (or 304.8mm) of shaft diameter (minimum of four per tier)
  • Maximum six (6) foot (or 1.83m) spacing from the top of the shaft
  • Maximum two (2) foot (or 0.61m) spacing from the bottom of the shaft
  • Maximum eight (8) foot (or 2.44m) interval spacing along the longitudinal axis of the shaft
