    • 9. Do you require expert advice and support? Be sure to choose a waterproofing system that has a track record of being supported by the local distributor as well as the manufacturer. Proper support should include reviews of project specific designs and details, clear literature on the product or system, application instructions, training, online help, and site visits. Suppliers should be available and always willing to help. 10. Does the manufacturer have a long history of success?

Integral systems can add decades to the life of a concrete structure. Unlike membrane systems that can deteriorate over time, integral systems become part of the concrete matrix, waterproofing from the inside out. This gives these systems added reliability over other waterproofing systems as they cannot be punctured or torn. In addition, integral systems won’t be worn away by constant Krystol® Magazine

    • at the support columns inside the tank. These columns often corrode at the base where they are thoroughly saturated by water. In severe cases, the concrete may be worn away, leaving exposed rebar that needs to be protected. Consult an engineer before removing deteriorated concrete from columns, especially if this requires chipping inside the rebar cage. Also look for honeycombing on the outside and inside of the concrete walls. Poorly consolidated concrete can lead to honeycombing and these areas will actively leak unless repaired. Finally, check the tank lid. Too often, water tank lids are not waterproofed or sealed. This can result in contaminated standing water on the outside of the tank making its Over time, this support column corroded at the base exposing the rebar reinforcements.way into the water in the tank – a major health hazard.

Cracks have been filled with Oakum to stop water flow, epoxy coatings have been applied or polyurethane plastic liners have been welded together inside the tank to block water leakage. While these methods may have provided temporary relief, none have proven as effective as integral crystalline waterproofing. Cracks and defects repaired with crystalline systems will outlast traditional epoxy or urethane repairs. Crystalline repairs can also be complemented by applying a full crystalline surface treatment to protect the concrete walls from further damage. Using integral systems for water tank repairs can protect tanks from deterioration and extend the structure’s service life, provided that the repairs are made before the deterioration becomes too severe. Because of this, the popularity of crystalline systems is booming and water tanks around the world are standing the test of time. This concrete was poorly consolidated, leading to honeycombing and leaking. Krystol® Magazine

    • Kryton in the United KingdomFor the past decade, Kryton has been involved in the UK end of the tunnel with more investments returning to the market construction industry. During this time a lot has changed: and many new infrastructure projects commencing. This opens standards and codes have been tightened and demands for the door to concrete waterproofing opportunities.concrete products have fluctuated depending on economic times. The global economic downturn in recent years has had With a well-established ready mix channel in place that has significant effects in the UK’s concrete construction industry. In approximately 1,000 concrete batching plants across the country, 2008, concrete sales fell 20 per cent and dropped a further 28 per Kryton continues to be a valuable concrete waterproofing cent in 2009. In 2010, the industry started seeing the light at the partner for the industry. Olympic Canoe Slalom Course, LondonLondon’s Olympic Canoe Slalom Course will soon be paddled by the world’s best athletes. Part of Lee Valley White Water Centre, the 2012 Olympic course features computer designed substructure to ensure Olympic standard rapids and includes a competitive and training course. These courses are fed by a man-made 10,000 square metre lake that, with the help of high powered pumps, supply 15 cubic metres of water per second. The structure integrates 800 cubic metres of concrete containing 5,600 kilograms of Krystol Internal Membrane (KIM). Effective and guaranteed waterproofing is critical for any structure integrating such water volume and pressure. KIM ensures the course will remain accessible to and safe for athletes and visitors long after the Olympics are over.Longwood Home, HaleLocated in one of Cheshire’s desired neighbourhoods, Longwood on Hilltop is a mansion that showcases luxury and contemporary living. The six bedroom six bathroom home features a variety of amenities, including a swimming pool, greenroom, sauna and spa, gym, cinema, games room and office. Before construction, the development team extensively researched reliable waterproofing systems that could adapt to the area’s geographical challenges. Their research led them to Kryton’s KIM waterproofing solution. KIM was added to the concrete formwork in the basement. Nearing completion, the mansion will be put on the market for approximately £4 million.One Housing Group, StratfordOne Housing Group has embarked on a development tower that will be a featured part of the tall buildings that form a gateway of Stratford City and the 2012 Olympic sites. This tower is composed of 17 floors and will feature 113 residential units, commercial units, communal gardens and a courtyard. One major task during construction involved waterproofing the building’s water tanks and basement. This was a challenge due to the building’s innovative design, which included an awkward perimeter and steel sheet pilings on all sides. To deal with this, the design team used 250 cubic metres of KIM mixed concrete and another 150 lineal metres of the Krystol Waterstop System. The redevelopment is now on track and, at £20 million, on budget.  www.kryton.com
    • Central Street, LondonTouted as one of the largest land deals in Central London, Central Street is a residential and commercial hub covering seven blocks and two acres. The development, which ranges between five and ten stories, consists of 274 homes and 4,500 square metres of commercial space. It is not only a landmark development for the area but also a key project for Kryton as it is one of the largest basement waterproofing projects ever undertaken by the company in the UK. Approximately 3,500 cubic metres of KIM concrete was used in the basement and 1,000 lineal metres of the Krystol Waterstop System were used on the joints. Waterproofing work began in April and is expected to be complete in August. Supermarket, WalsallWhen it came to waterproofing the service yard area of West Midland’s new £17 million supermarket development, Kryton was a simple choice for concrete flooring contractor Snowden Flooring Limited. The 2,600 metre square service yard, located on the first floor of the building with car parking below would be used by articulated lorries, or big rigs, when delivering goods to the store. The concrete slab needed to be watertight to ensure the parked cars underneath stayed dry as well as durable under heavy and constant pressure from the rigs. A precast/in situ composite deck incorporating KIM was used to waterproof the slab. KIM not only increased the slab’s durability but also gave the concrete enhanced freeze/thaw durability and de-icing salt resistance.
