Pressure pointing and grouting are used in combination or isolation as means to repair and strengthen masonry structures including arched bridges, retaining walls, dams and culverts.
Pointing work can use hand held barrel guns, or for more intensive applications, mechanical mortar pumps delivering lime or cement based material through a hose to the point of placement.
Pressure pointing can be effective on open joints up to 200 mm deep, but in such circumstances the combination of pressure pointing to a lesser depth coupled with low pressure grout injection can be more economic.
Such work often calls for preliminary cleaning of masonry surfaces using high pressure water jetting equipment, and removal of decayed mortar using a variety of hand and mechanical methods.
