Water stop and kicker uses in detail


The tendon stop is a plastic roll (and there are metal types) its width is from 20 to 30 cm, the length of the roll is about 30 m linearly and there are different zigzags and protrusions according to the need for use, it may be smooth on one hand, and on the other hand it has burrs, it has burrs on both sides About 10 mm, and in this article, through the website of the Specialized Trading and Contracting, we will learn about the importance of installing a water stop.

Areas of use of the chord stop

  • It is used when pouring the floor of the water tank, as it is placed inside the tank floor on the side of the tank wall, and part of it is about 12 cm. The rest is protruding upwards and is inside the tank wall when pouring concrete.
  • In general, a water seal is used when there is any separation inside the floor, the walls of the water tank or the swimming pool, and its purpose is to prevent leakage in the formwork or expansion joint.
  • We also use it in concrete walls that are poured in two stages, and it is feared that the concrete separator resulting from the stoppage of pouring will cause water to leak from it.
  • They are positioned so that the lower half is poured into the first part of the wall and the upper half is left without pouring to be poured with the completion of the concrete wall, such as swimming pools, water tanks and basement walls
    It can also be used in concrete floors that can be poured in two stages such as reinforced concrete plaster, which is preferably poured in one stage without stopping.
  • It is fixed by hanging from an upper iron bar through the holes in the bar by attaching it to the drawstring wire.
  • In general, a stopper is used in any place where there is water, whether the water is from the inside or from the outside.
  • It is one of the lines of defense against water and not the only one, since any structural fracture in the structural element is considered a vulnerable area, precautions must be taken to prevent the penetration of water from the interior or into the element.
  • It can be used with a water sealer and some chemicals to bond old and new concrete, but not always as it may not be used just before pouring.

The water stop and its relationship to the kicker

If the pouring spacer will be between the base and the wall, it is recommended to make what is called a kicker, which is a small height between 15 and 25 cm from the wall and is poured with the base, here half of the insulator is installed in the kicker and half of it protrudes to be poured in the next stage. Apply it to any molding interval, whether between the wall and the base, between the wall and the ceiling, or between the wall itself in two stages of forming.

Water stops are placed at each terminal in the construction joints, as well as at expansion joints and stabilization joints, regardless of the tank location, whether it is ground, buried or overhead.

The water stop must be installed before pouring, so that part of it is placed in the first stage and the second part in the second stage of the walls when we have a water stop in cases of the basement or retaining walls (in the case of groundwater) or the walls of tanks and purification stations in order to install a barrier Water in an area that does not intersect with the rebar.

The water stop shall be made of non-biodegradable materials and does not affect the quality of the water, to withstand shear forces when pouring the wall where the lifter prevents the movement of the moulds.

The hitch acts as a wrench to the wall so that tension does not apply when clamps are tightened to each other and kicking is mandatory to perform.

In the case of walls when there are groundwater and reservoirs.

Water stop installation

Installation is carried out carefully and precisely in terms of:

  • One lap length.
  • Install half on top of tank or cap.
  • And the other half with the perimeter, in addition to the layout of the stop strings for the vertical walls, the pre-cast
  • perimeter with the participation of the post-cast contour.
  • Attach the stop coil to the sticks in the middle with a connecting iron wire.
  • Glue and combine the first roll with the second roll with an electric soldering iron.

Use the chord stop

  • Floors and walls of water tanks.
  • Swimming pool.
  • Separator between walls and surfaces.
  • Infrastructure works.
  • Water works.
  • A spacer between the wall and the adjacent wall.
