Types of hydraulic plows for sealing seams in concrete structures
Hydro-shponka is a reliable material for waterproofing construction and expansion joints in monolithic construction. It prevents moisture from penetrating through the joints and ensures the durability of concrete structures.
Types of hydraulic dowels
Depending on the purpose, the following types are distinguished: 
Where are hydraulic wedges used?
-
Internal and external hydraulic joints are used to seal construction joints (cold joints, joints during concreting breaks). -
External and internal keys, as well as U-shaped keys, are used for expansion joints in monolithic structures.
-
In complex construction projects, different types of hydraulic dowels can be used in combination to achieve maximum reliability.
Advantages of using hydraulic dowels: 
-
reliable waterproofing;
-
durability and resistance to aggressive environments;
-
possibility of use in foundations, tanks, pools, tunnels, hydraulic structures;
-
versatility of installation.
Hydro plugs are an effective solution for protecting concrete structures from leaks and destruction.
