What is Sikadur®-42 TH?
Sikadur®-42 TH is a three-component, solvent-free, castable epoxy resin grout consisting of high-strength epoxy resin and specially graded aggregates. When mixed, it forms a highly flowable mortar suitable for grouting applications and filling various gaps and voids.
Main Applications of Sikadur®-42 TH
This product is a high-strength, self-leveling, and non-shrink grouting material suitable for:
Grouting beneath bridge bearing plates
Machinery foundations
Anchoring bolts and anchors
Crane rails
Reinforcing steel applications
Filling cavities or voids in concrete

Mixing Method
Mix Components A and B for at least 1 minute.
Use a low-speed drill at no more than 400 RPM.
Add Component C.
Continue mixing until a homogeneous, free-flowing mortar is obtained. sikadur_-42_th
Application Method
For grouting beneath bearing plates, sufficient pressure or head must be maintained to ensure continuous grout flow, and adequate openings must be provided to allow trapped air to escape.
For large-volume applications, the grout should be poured in multiple layers, allowing each previous layer to harden and cool before pouring the next layer.
