Solid bars are usually installed into pre-drilled holes and then grouted into place using a separate grout line, whereas hollow bars may be drilled and grouted simultaneously by the use of a sacrificial drill bit and by pumping grout down the hollow bar as drilling progresses. Kinetic methods of firing relatively short bars into soil slopes ...
Grout sealer is a water-based or solvent-based sealant applied over dried grout that resists water, oil, and acid-based contaminants. Grout cleaner is a basic cleaning solution that is applied on grout lines and removes the dirt and dust. [9] A die grinder is used for faster removal of old grout compared to a standard grout saw.
Pressure grouting or jet grouting [1] involves injecting a grout material into otherwise inaccessible but interconnected pore or void space of which neither the configuration or volume are known, and is often referred to simply as grouting. The grout may be a cementitious, resinous, or solution chemical mixture. Some types of injected grout may ...
It is created with a grapevine jointer, which is a metal blade with a raised bead that creates an indented line in the center of the mortar joint. These lines are often rough and wavy, simulating the generally straight yet slightly irregular appearance of a grapevine. It is commonly used on matte-finish and antique-finish brickwork.
A spacing between tremies of between 3.5–5 m (11–16 ft), and a distance of about 2.5 m (8 ft) from the formwork has been recommended. The risk of segregation and uneven setting can be minimised by providing a continuous flow of concrete through all the tremies to maintain a moderately even top surface.
A grout curtain is a barrier that protects the foundation of a dam from seepage and can be made during initial construction or during repair. [1] Additionally, they can be used to strengthen foundations and contain spills.
