ARFEN hydraulic spigots: technical solutions for sealing seams

What is an ARFEN hydraulic wedge and what is it used for?

ARFEN hydro-joint is a PVC profile designed for sealing construction and expansion joints in concrete structures . It prevents groundwater penetration, compensates for concrete movements and ensures the durability of monolithic objects. It is used in foundations, underground parking lots, tanks, industrial floors, tunnels and hydraulic structures.

What are the main types of ARFEN hydraulic dowels and how do they differ?

Type A — internal working seams.
Installed in the body of concrete, ensures sealing of the joint during pouring.

Type AA — external working seams.
Mounted on the side exposed to moisture, effective for foundations and underground structures.

Type D — internal expansion joints.
Compensates for sedimentary and temperature movements, used in long-term facilities.

Type DA — external expansion joints.
Guarantees maximum protection against hydrostatic pressure in seams where the structure experiences “play”.

Thus, each type of ARFEN PVC hydro-plug is optimized for specific load and operating conditions.

In which facilities is it advisable to use PVC hydro-joints?

PVC waterstops are recommended for:

• foundations and retaining walls;

• 

  floor slabs and monolithic floors;

• underground parking lots and tunnels;

• tanks, pools and treatment plants;

• sealing of seams in hydraulic structures.

ARFEN provides the required level of tightness even at increased hydrostatic pressure.

What are the advantages of ARFEN hydraulic dowels for designers and developers?

• high elasticity and deformation compensation;

• resistance to aggressive environments;

• durability in monolithic structures;

• easy installation thanks to eyelets and correct profile geometry;

• wide selection of series for construction and expansion joints.

These characteristics make ARFEN hydro-plugs a reliable solution for project-based waterproofing systems.

What are the requirements for the correct installation of the ARFEN hydraulic wedge ?

• Welding of joints is performed with a special ARFEN soldering iron .

• The profile must be precisely fixed in the joint before concreting.

• Installation is carried out along the reinforcing frame using wire or clamps.

• It is forbidden to move the key during pouring - this may disrupt the integrity of the hydrobarrier.

Compliance with these requirements guarantees the design tightness of the seams.

Where can I buy an ARFEN hydraulic wedge with technical support?

On the Protex website you can buy a PVC hydro-joint with professional advice, selection of the type for a specific object and a quality guarantee. All models are available - A, AA, D, DA - for construction and expansion joints of any complexity.
