Hydrophilic Swelling Waterstop

Hydrophilic waterstop PROFILES and SEALANTS are used in construction joints in  commercial and residential below ground structures with a low to medium ground water pressure.

Applications include pipe and steel work penetrations through walls and floor slabs, connecting joints in diaphragm walls, construction joints in in-situ and precast concrete, cable ducts and more.

Hydrophilic expandable waterstops, also known as swelling rubber waterstops, are specifically designed to function as sealants that prevent moisture infiltration and water migration in to seal all types of joints and penetrations in concrete, including cold joints and construction joints. These waterstops possess the unique ability to expand by over 400% in volume when exposed to moisture, forming a flexible and watertight compression seal.

Polymer waterstop(vulcanized rubber) is a synthetic rubber waterstop that uses swelling pressure to seal concrete construction joints and stop the water. Polymer waterstop has superior swelling pressure and performance that stops water better than bentonite and competing swelling water stops. It is suitable for use with regular groundwater as well as salt and sulfate- contaminated water. Polymer waterstop is extremely durable and will not deteriorate over time.

Cold joints and construction joints represent areas in concrete structures that are particularly susceptible to leaks and cracks due to water penetration. Unchecked water ingress can lead to a range of issues that compromise a structure’s integrity, including:

Rebar corrosion: Water infiltration can cause corrosion in the reinforcing steel, which may weaken the structure over time.
Expansion cracks: Expansive forces resulting from water penetration can lead to the formation of cracks in the concrete

Frost and thaw cycle damages: Repeated cycles of freezing and thawing can cause deterioration in concrete structures, particularly in colder climates

Health hazards: Mold and fungus growth resulting from moisture infiltration can lead to adverse health effects for occupants.

By employing hydrophilic expandable waterstops in cold joints and construction joints, builders can mitigate these risks, ensuring the longevity and stability of concrete structures.
