the basis for a watertight construction joint
joints with demands for tightness is strongly recommended
produced with grooves. 2"x4" boards in falling lengths
should be given a bevel cut at two sides as shown at the figure, to
obtain good slip and economic reuse.
If necessary adjust the width.
boards are tied "butt in butt" to the reinforcement as the
figure shows. Fish over joints
and in corners.
forming boards on end forms in wall and paving, see the installation
forming boards must be removed as soon as possible after pouring, and
burr edges smoothened. Clean
the construction joint with air- (water), and install the injection hose
before the reinforcement courses too much obstacles.
If Ultra is harmed or damaged, it must
properly be wrapped with tape or exchanged.
grooves are left out, the surface should be smoothened to
secure a rapid and reliable installation of Ultra.
With Ultra injection hose in concrete, on
stone or steel, you will get all
the flexibility and security you wish for!
