Lateral junction renewal restores and seals the connection between the main pipeline and lateral services using trenchless techniques, avoiding excavation while delivering a durable, watertight result.
Using internally applied, resin-cured fittings bonded to both the lined main and lateral connection, this process prevents infiltration, root intrusion, and joint deterioration, helping extend asset life while minimising disruption on site.
The Latseal LJR is an internally applied, resin cured fitting that provides a secure long-term seal by bonding with the lined pipeline and the house lateral. The Latseal consists of a glass fibre composite sock that is saturated with silicate resin and mounted on a packer. The sock typically extends (covers) up to and beyond the first joint up the lateral.
Installation is a non-disruptive process. The Latseal is installed by accessing the nearest manhole. A Latseal installation can take place in under 50 minutes.
The innovative packers have been designed for smooth entry into the lateral with a minimum of pushing/pulling force. The controlled bending mechanism inside the lateral arm allows for reliable insertion and withdrawal from the lateral.
Latseal packers use an innovative rubber design that allows controlled and staged inflation as well as providing firm pressure on the liner that promotes excellent adhesion. Packer has flow through tubes, so no flow bypass is necessary.
Latseal liners are made from a woven glass fibre material. This innovative material provides the dual feature of being both very strong (E Modulus > 3,000MPa) and highly stretchable (>50% diameter change).
This means that Latseal seals are both strongly adhered as well as being structurally sound in their own right. Furthermore, the high elongation means that when pressed into place by the Latseal packer, maximum surface area contact is achieved between the liner and host pipe. This is essential to enable the liner to have a high adhesive strength to the host pipe.
Supercil resin is the latest in Silicate resin technology. Supercil™ resin is a very stable and fast curing resin. The resin is insensitive to Ambient Temperature meaning one resin can be used for all seasons. The resin is thixotropic for easy and straightforward impregnation. Supercil resin has the unique property in that it is 100% immiscible with water i.e. it does not mix with or be diluted by water.
Supercil resin has superior chemical resistance against most chemicals including harsh industrial solvents. Supercil has been exposed to an extensive list of chemicals. The test reports can be provided from the product’s Technical Guide Appendix B.1
