XP 230 Epoxy Grout for Wind Applications

Eliminate the Plate. Simplify the Process.
Get a Stronger Base and a Bigger Bottom Line.

Five Star® Xtreme Performance XP 230 Epoxy Grout is a wind tower bearing plate elimination system with an industry-leading compressive strength of 23,000 psi (159 MPa). A three-component engineered system, it is low exothermic, 100% solids, solvent-free, and non-shrink as tested per ASTM C1090 with high fatigue resistance under dynamic conditions. Ultra-high compressive strength spreads the load between the tower and foundation in one step, eliminating the need for a two-step installation of an expensive steel bearing plate. Once cured, a full-contact, weather-tight connection between the tower and foundation is formed, creating a stronger connection between the dynamic tower and its static foundation than is possible with a steel-bearing plate. Low exotherm and high flow mean it can be poured up to 14 inches (36 cm) deep in a single lift with a working time of 45 minutes. High early strength of 10,000 psi (69 MPa) is achieved in 4 hours at 90°F (32°C) and 8 hours at 70°F (21°C) to facilitate cost-saving installation of additional tower sections in as little as one day.



Lower Installed Costs

  • Ultra-high compressive strength eliminates the high cost steel bearing plates in many large wind tower applications

Increases Performance Confidence

  • High dimensional stability, non-shrink per ASTM C1090
  • High fatigue resistance under dynamic loading conditions
  • Coefficient of Thermal Expansion and Modulus of Elasticity more closely aligned with steel and concrete
  • Low exotherm enables higher monolithic pours

Increases Scheduling and Cost Predictability

  • Early strength development enables faster jobsite progress (i.e. torquing bolts, stacking additional tower segments)
  • Reduces supply chain complexity and scheduling uncertainty asso- ciated with steel bearing plate

Easy to Use

  • Long working time
  • Place up to 18 inches depth in a single pour
  • Low dust formula
  • Use current epoxy grout installation techniques


  • Wind towers or other high load applications
