Product Detail
1.Sealing joints between pipes 2.Contact with water expand to about 350% 3.Easy application with caulking gun



Swellseal Mastic is a one component, polyurethane based, solvent free, hydroswelling mastic, supplied in cartridges and aluminium sausages, for the sealing of construction joints and around pipe penetrations

Swellseal Mastic cures and swells in the presence of moisture. Curing time depends on temperature and humidity conditions, i.e. curing time will reduce if RH and °C are higher. Swellseal Mastic will become firm in 24-36 hours. Performance is not affected by the curing time


Field of application:


1.Sealing rough and smooth construction joints of in-situ cast concrete

2.Sealing joints between pre-cast segments(e.g. manholes, box culverts, cable ducts and pipes)

3.Sealing around steel H-beams

4.Sealing between rough surfaces(e.g. slurry walls) and concrete slabs

5.Bonding strip sealants to rough surfaces

6.On secant pile walls



   1.Solvent free

   2.Swellseal Mastic can be applied to concrete, PVC, HDPE, STEEL, ect.

   3.The excellent filling and adhesion properties of the product provide a first line filling of cracks and voids, even on lightly humid, smooth or rough surfaces

   4.In contact with water Swellseal Mastic will expand to about 350% of it’s original volume

   5.Flexible system, which adapts to the irregular surface of the substrate

   6.Easy application with standard calking gun

   7.Durable: will exceed the construction’s life

   8.Has a good all-round chemical resistance and can resist to petroleum, mineral and vegetable oils and greases

   9.Swellseal Mastic is approved for contact with potable water




1.Swellseal MASTIC is preferably applied onto a dust-free concrete surface. The surface can be rough , smooth, dry

Installation during heavy rain or in prolonged contact with water results in a premature swelling of the strip, which should be avoided

Preferably the MASTIC should cure for 24 hours before pouring concrete

Despite the fact that Swellseal MASTIC has a very good MASTIC to the concrete, care must be taken, as with all products of this type, not to pour the concrte directly on the product to avoid damaging of the applied sealant

2.Application method:

Put the sausage in the empty tube of the calking gun and cut 1cm off the top of the sausage. Close the tube and install the nozzle. Cut the nozzle diagonally at the appropriate position

Swellseal MASTIC is applied with a calking gun in an uninterrupted band(minimum 10mm wide and high), In the middle of the joint or prefab element. Concrete cover should be at least 7cm on both sides, in order to avoid cracks from the expansion pressure of swelling Swellseal MASTIC
