Injection Hose Waterproofing, Jersey

Summary

• 

  Injection ports were also fitted every 10 metres.

• 

  The one-shot injection resin completely sealed the joints.

• 

  The injection hose was fitted before the concrete pour.

For this residential project on the Island of Jersey, a homeowner was building a private underground car garage with their own tennis court on top. To help ensure a completely dry basement, Rateavon Jersey installed Newton’s injection hose waterbars in the construction joints.

The Solution

With such a specialist installation required, Castletree called on the expertise of the Newton technical team. They worked alongside Newton Specialist Contractor Rateavon Jersey in order to provide the waterproofing installation and guarantee.

With the Type A Newton HydroBond System and concrete slab in place, Rateavon began by installing 80 linear metres of Newton 302 Injection Hose. The team completed this in 10-metre lengths along the top of the kicker joint. The team fixed the injection hose at 150 mm centres using clamps shot-fired into the concrete. This ensured minimal movement during the remainder of the concrete pour. To complete the Type B system, they installed injection ports at the end of every 10-metre length of hose at a height of 1 metre above the slab.

Finally, the remaining concrete was poured and cured for 28 days, and the internal Newton CDM System was installed. Rateavon used the new ports in the concrete walls to inject the whole system with a one-shot treatment of PC Leakinject 2K Flex 6811 LV. This cures with or without water to provide a flexible, resilient seal within the kicker joint.

The Newton CDM System

The Newton CDM System is a comprehensive Type C waterproofing system. This is usually suggested as a form of waterproofing to provide superior protection against water ingress, particularly where a completely dry internal environment is required.

The Result – Injection Hose Waterproofing

By combining all three Types of waterproofing, as defined by British Standard 8102:2009, Newton provided the client with the ultimate protection from water ingress. The new concrete structure will also provide a guaranteed Type B form of waterproofing. This is because of the high-quality concrete pour and expert installation of the injection hose.
