As one of the UK’s leading drainage and wastewater specialists, we are always pioneering the most effective and innovative ways to provide better drain, sewer and wastewater services for our clients.
Faulty rain and foul water stacks are a prime cause of dampness and mould in high-rise flats. Hot water and ambient cure CIPP systems are not always safe or able to carry water in the liner on high-rise flats.
The manager of the Lanes Birmingham Depot states that “stack repair has been a challenging problem in high-rise buildings for years.”
After years of difficult high-rise flat-lining. The Birmingham Depot Manager has had much success with LED light CIPP systems, leading him to head up the company’s investment in the Brawo Magnavity technology.
Lining stacks on high-rise blocks of flats is challenging due to the pressure differences across the building.
Hot water CIPP is only suitable depending on the weight of the water in the liner, and ambient cure CIPP can be risky because of the unpredictability of curing times and the production of toxic vapours during the process.
The challenging nature of pipelining in high-rise buildings often leads to disruption for tenants and landlords.
We became the first contractor in the UK to line tall building drain stacks using the Brawo Magnavity LED light cured-in-place pipe (CIPP) system supplied by trenchless technology specialist S1E.
This completely transformed the rehabilitation of vertical drainage stacks in high-rise buildings. It significantly sped up the previously difficult process of lining both rainwater and foul stack pipes, with less disruption, less energy, and less material waste.
The system makes lining drains in high-rise buildings much easier and more sustainable, just at a time when problems caused by faulty drainage systems are becoming a maintenance priority for social housing landlords.
The process involves inserting a resin-impregnated flexible felt liner, often with a polyurethane or polypropylene coating, into a pipe. The resin then cures to create a tough, waterproof pipe-within-a-pipe, eliminating defects.
The light head has 96 LED lights, with an electric magnet on the front which decouples from a second magnet to carry out the curing run along the pipe.
The Brawo Magnavity system uses LED light to cure the resin. Its LED light array is combined with a powerful electric magnet that holds the lights in place as the liner is inverted into the pipe with compressed air.
Once the liner is in place, the light pack, with its 96 UV LED lights, detaches from the magnet and cures the resin at a speed of up to 0.6 meters a minute as it is pulled back through the pipe.
Because the magnet guides the liner so effectively through the pipe, it can negotiate multiple bends up to 90 degrees, something other CIPP systems fail or struggle to do.
The specialist 3D liners used by Lanes Drainage Services are flexible so they can easily accommodate changes in diameter in the stack pipes being lined.
The system, which can also be used on horizontal pipe systems, also allows liners to be ‘blind shot’ into pipes from a single chamber rather than between two chambers.
The advanced low-odour resin developed by Brawo is stable until exposed to UV light, giving the Lanes lining team all the time it needs to prepare the liner for curing. By contrast, ambient cure liners must be inserted at a specified time before the resin starts to harden.
Just two Lanes operatives can operate the system, which can be quickly set up in a small space to line both vertical and horizontal small-diameter pipes much more quickly than conventional systems.
With light-curing pipe repairs, we can install and cure multiple stack liners in just a few hours.
If you’re a landlord, housing association or property manager in need of a faster and more efficient solution to a high-rise pipe challenge.
