Connect Plus

Connect Plus combined with Silica Sand is a unique Bentonite based two-part, field mixed, high to extreme-high solids grouting material that can be mixed to meet a range of thermal conductivities from 0.78 – 1.78 Wm-1 K-1. Unlike many other grouting materials, Connect Plus requires less water per delivered litre of yield.



  • Specifically developed for closed-loop ground coupled heat pump applications where thermal conductivity in the bore column is critical to system performance.
