Bentonite cord for sealing holes with a diameter of 22 mm

Bentonite cord for sealing holes with a diameter of 22 mm

In modern monolithic construction, special attention is paid to sealing technological holes in concrete. One of the most effective solutions for this task is bentonite cord "Gidrostop" Ø22 mm . This is a proven material that provides reliable sealing of holes for tie screws that remain after dismantling the formwork.

Protex offers this cord at a promotional price , which makes it a particularly advantageous choice for professional builders, installation crews, and companies engaged in the construction of monolithic structures.

Purpose and principle of operation

During the installation of the formwork, plastic non-removable tubes Ø22 mm are inserted into it, inside which tension screws pass. After the completion of concreting and stripping, the screw is removed, leaving a hole in the concrete. Such a hole needs to be sealed, and this is where bentonite cord works effectively.

The cord is inserted into the hole left, after which the edge is covered with a waterproofing solution. Upon contact with water, the bentonite contained in the cord swells 4 times , forming a gel that fills even microcracks, pores and voids. In a confined space, this gel creates hydrostatic pressure , which prevents water from penetrating .

Main benefits for builders:

✅ Easy installation – does not require special tools or highly skilled workers. The cord is simply inserted into the hole by hand.

✅ Repeatable reliable result – equally effective in both simple and complex concrete structures.

✅ Strong adhesion to concrete – the material is plastic, fits tightly to the walls of the hole.

✅ Versatility of application – suitable for use in both civil and industrial or underground construction.

✅ Resistance to aggressive environments – protects structures even in difficult operating conditions.

✅ Withstands pressure up to 7 atmospheres - ensures tightness even in places with high water pressure.

✅ Economic efficiency – low cost with high performance characteristics.

✅ Possibility of installation on a wet surface - convenient in conditions of rapid construction.
