Cable Bolt Grouts
• PUR70 is pumped (bottom-up) into Fully-Grouted Cable Bolts (FGCB) to provide corrosion protection and improve bolt life.
• TDS-240 is a urea silicate (top-down) grout that is used when high early strength is required as in longwall recoveries. Full strength is achievable in 4 hours.
Cavity Filling Grouts
• J-SEAL® is a high-strength foaming grout used primarily for rated seals. The J-SEAL placer pumps allow for control of the material density so that lower strength mixes can be used for cavity fill applications such as behind steel sets.
• US foam is a high expansion urea silicate foam (30:1) that can be used to rapidly fill cavities with minimum construction of formwork.
• JPH foam is a phenolic foam (50:1) that can be used also to rapidly fill cavities with minimum construction of formwork. Because of the low exotherm, greater volumes of material can be more safely placed at any one time.
