Waterproofing seams using a hydraulic punch

Waterproofing seams using a hydraulic punch

Waterproofing is one of the key stages in the construction of monolithic and prefabricated reinforced concrete structures.

Any reinforced concrete structure requires the presence of construction joints, cold joints (for example, floor-wall joints), and expansion joints.

In this article, we will look at the method of sealing seams using a hydro-dowel.

The principle of operation of a hydraulic wedge

A waterstop is a special waterproofing gasket in the form of an elastic PVC or TPE tape with ribs. Thanks to these ribs, water cannot pass through the seam unhindered: the path of moisture movement is significantly extended, which ensures reliable sealing.

Installing a hydraulic wedge is simple and convenient:

• the key easily joins together;

• no special equipment is required for installation - a construction hair dryer for welding joints and binding wire for attaching to the reinforcing frame are enough;

• All the necessary tools are usually available at every construction site.

Using a hydro-joint allows you to reduce the work time of builders and, accordingly, reduce labor costs. In addition, the cost of the material itself is quite affordable - the price of a hydro-joint starts from 50 UAH/m, which makes it an economical solution compared to other sealing methods.

Where is a hydraulic wedge used?

Using a hydraulic wedge you can do:

• sealing of cold joints;

• sealing of construction seams;

• sealing of expansion joints.

It is ideal for protection against leaks in foundations, floor slabs and other structural elements. Its use is especially relevant in the following facilities:

• water parks and swimming pools;

• tunnels;

• sewage treatment plants;

• hydraulic facilities;

• technical premises for storing hazardous waste;

• granaries and elevators.

A hydro-joint is a reliable, durable and economical solution for sealing joints in concrete structures. It provides effective protection of structures from moisture, extends their service life and significantly reduces construction costs.
