External waterstop HP 240 PVC for expansion joints, blue, 20 r.m., Sanpol Ukraine Sanpol
Hydraulic shponka HP 240 is used for sealing and waterproofing technological seams in monolithic construction of buildings, including foundations, underground parking lots, tunnels, canals, etc. Mounted directly on the formwork sheet from the side of the expected water pressure. They are made of thermoplastic elastomer TPE or plasticized PVC-p polyvinyl chloride.
- the shape allows it to be securely embedded in a concrete structure
- the presence of ribs on the locking plane prevents the penetration of moisture into the structure
- it is used when concreting monolithic reinforced concrete structures is interrupted
- in particularly important constructions, it is supplemented with an internal hydraulic gasket
- it can be used in structures with special requirements to ensure tightness
- withstands high water pressure from the outside
- easy to install, does not require changing the reinforcement frame
- suitable for all kinds of designs
- It is delivered in rolls of 20 m.p.;
External (external) Sanpol hydraulic studs for working seams HP seriesThey are used for sealing and waterproofing technological seams in the monolithic construction of reservoirs, swimming pools, sewage treatment plants, dams, buried and underground structures, collectors, etc. They are mounted directly on the formwork sheet from the side of the expected water pressure.
The shape of the hydraulic spar allows it to be securely embedded in a concrete structure, the presence of ribs on the plane prevents moisture from entering the structure.
Advantages of using:it is used during a break in the concreting of monolithic reinforced concrete structures, in particularly important structures it is supplemented with an internal or external hydraulic gasket
- it can be used in structures with special requirements to ensure tightness
- withstands high water pressure inside and outside
- easy to install
- does not require changing the reinforcement frame

How to install a waterstop?
The hydraulic joint is installed in the design position, so that the middle of the hydraulic joint is located in the center of the intended deformation seam.
Fastening is made directly to the formwork. Holes for fasteners are allowed to be made only in the extreme zone of the hydraulic shponka, behind the extreme anchor. The mounting pitch is 200-300 mm, symmetrically on both sides. Additional fastening is also made to the reinforcement frame with knitting wire.
The connection of the key is made by welding, by heating the ends of the key in a special conductor (for each key there is an individual conductor) or using an industrial hair dryer or a flat heating element. The temperature of the spike is about 200 ° C (selected experimentally). To connect the dowels by the "cold" method, glue is used, for example, a one-component paste-like glue based on the silane-modified polymer InnoElast.
