Joint Sealing

Featured image for Joint Sealing

Where you have new or existing construction joints in road surfaces made from asphalt or concrete it is necessary to fill and seal them appropriately. This not only allows the surface to tolerate expansion and contraction but also protects the joint from water damage, prevents the joint from failing due to other surface applications such as de-icer or from surface spillages.

Jointline provide joint sealing in a variety of ways:

Hot Applied N1 and N2 Sealants

Hot applied N1 and N2 sealants are used to maintain and repair joints in concrete or asphalt surfaces and are particularly used on highways, airfields and car parks. These hot applied sealants are fullyBS EN14188-1 compliant. They have excellent expansion and contraction qualities and are effective at preventing damage resulting from water and dirt. These joint sealants can be quickly and simply applied at any time of year and cure quickly, helping to minimise disruption to traffic or users of the area to be treated.

Cold Applied Fuel Resistant Joint Sealants

If the area to be treated has a high likelihood of fuel spillages i.e. aircraft fuelling areas, oil terminals, garage forecourts, parking and cargo areas then we would applied a fuel resistant sealant using a cold application method. As with the N1 and N2 sealants the contraction and expansion properties are excellent and provide joint protection from water, dirt and more importantly kerosene, petrol and aircraft fuel.

As well as simply sealing joints Jointline have specialist saw cutting equipment to;

  • Create joints in new/green concrete to enable the surface to deal with expansion and contraction 
  • Chase out or existing concrete cracks and sealing them or overbandingthem
  • Reform existing joints to effectively reapply sealant.
