KingGrout GP20®
Pump applied, non-sagging cementitious joint filler for vertical joints of concrete elements.
Overview
KingGrout GP20 is a single component, polymer modified mortar specially designed to fill the vertical joints of concrete elements. KingGrout GP20 is a blend of dry powder, well graded aggregate, fibers and special additives which when mixed with water produce a thixotropic mortar especially designed to fill the vertical joints without sagging using a proper pump and without a need to use formwork.
Applications
- Filling the vertical joints between concrete panels
- Filling cracks, holes and groves in concrete substrates
- Casting top and bottom joints of wall elements
Advantages
- Shrinkage controlled mortar, reduces the risk of cracking due to shrinkage and ensure full contact with host concrete
- Easy to apply, single component, requires only addition of water
- Thixotropic properties allowing extra high build for vertical applications
- Extremely low permeability to water, providing excellent protection to steel reinforcements and host concrete
- Cost effective, pump applied no formwork is required

If the joint is opened on the both sides, place a stopper board on one side of the joint. Remove the stopper board once sufficient amount of time has elapsed depending on the working conditions and use a trowel to finish the joint. The mortar can be applied using a normal screw pump. Pump the mortar carefully into the joints to ensure that the joint is thoroughly filled with the material and obtain a structurally functional joint. For the application behind reinforcement bars, a piece of steel tube with a pointed tip is attached to the hose to allow the ease of application. | ASTM D2369 |
