SIKA Liquid Plastics offer the following product ranges:
Warm Roofs – Built up Roofs:
Sika Liquid Plastics launched its built up roof system in 2004, which signalled a revolution in roofing systems due to its completely flame free and heat free installation. Since then the market has evolved with more clients requiring cold applied options with improved workability.
Sika Liquid Plastics manufacture elastomeric seamless polyurethane coating systems that are suitable for the waterproofing of new and the refurbishment and upgrading of existing cold flat roofs.
Sika Liquid Plastics offer a variety of liquid roofing system and are celebrating the 30 year anniversary of their pioneering flagship product, Decothane. They have further developed this patented technology to launch Decothane Ultra – a low odour, cold-applied solution, ideal for sensitive sites.
Sika Liquid Plastics’ Inverted Roof System offers many advantages over traditional warm and cold low pitched flat roofs. Not only is the system completely cold applied, it is also totally seamless.
A green roof is the term applied when vegetation such as sedum, plants and trees, are installed on a building. There are three types of green roofs; Extensive Green Roofs, Biodiverse Roofs (Extensive Brown Roofs), and Intensive Green Roofs.
A roof was once seen only as a means of protecting a building from the elements. But now, through the installation of solar panels, it has become a valuable resource for building owners.
Sika Liquid Plastics has developed a range of special asbestos encapsulation systems known as Asbestolok® designed specifically for asbestos roofs. Once installed, the system enables the asbestos to be left undisturbed and will provide protection from all of the associated dangers.
Waterproofing of Balconies and Walkways:
Sika Liquid Plastics has a wide range of solutions for Balconies and Walkways with guarantees of up to 20 years. They have developed a fast-curing PMMA system Sikalastic Rapid with potential curing time of 15-20 minutes – ideal for situations with restricted access or where fast application is required.

DURABLE SIKA PRODUCTS MAKE STUNNING BEACH DEVELOPMENT FIT TO FIGHT THE ELEMENTS
DURABLE SIKA PRODUCTS MAKE STUNNING BEACH DEVELOPMENT FIT TO FIGHT THE ELEMENTS
The Dunes, a stunning new beachfront development in Perranporth, Cornwall, has seen a combination of Sika products used in order to create a durable solution for the roof and balconies, able to resist the difficult coastal weather conditions.
While the beach setting provides the 36-property development with a spectacular backdrop, it also presented many challenges due to problematic climate. With the roof and balconies needing to guarantee a long-lasting result, Sika Sarnafil and Sika Liquid Plastics systems were specified for the job, working together seamlessly to create the desired result for the project.
Progressive Systems, a leading roofing contractor in the south west, was tasked with carrying out the installation. Having worked with Sika before, they suggested Sika Sarnafil single ply membrane for the roof, as the adaptability of the material would be durable enough to resist the elements, with a look to equal the prestigious coastline location.
Wind uplift calculations were provided by Sika Sarnafil to the contractors, which suggested the product be mechanically fixed to ensure the roof was able to resist the formidable weather. With a combination of Sarnafil’s S327 18 EL Lead Grey single ply membrane, plus Sarnavap vapour control and SarnarTherm insulation, the outcome was a robust roof that met the requirements of the project.
For the balconies, a Sika Liquid Plastics system was suggested to provide a complete watertight solution. With the installation handled by Western Flat Roofing, a Sika Liquid Plastic’s Quality Assured (QA) contractor, they chose to use Sikalastic 625 grey (PU), cold applied system with self-adhesive on a tapered insulation scheme, creating seamless and durable waterproofing on the balconies.
The project and its location presented many opportunities to problem solve for both contractors and Sika. When installing Sarnafil’s single ply membrane health and safety was top of the agenda – in fact, the disruption caused by strong winds even resulted in aborted site visits on occasion. On the balconies, the installation of three-ton hot tubs meant the insulation scheme had to be designed to allow water flow around the fixed structure, while complying with the correct U-value and withstanding the weight. However, regular visits from Sika’s Field Technicians meant queries were handled directly and quickly resulting in a successful installation and securing a 20-year guarantee for all Sika products used.
Alistair Speirs, Area Technical Manager at Sika said: “This build presented many challenges because of its positioning on the coastline and the difficult weather. However, the combination of Sika products along with the expertise of both the contractors and our technicians involved in the installation, meant the project was completed on time and within budget. We are all thrilled with the result in terms of the durability and the stunning aesthetic.”
The coastal conditions will be no match for the resilient solutions created by Sika, expertly installed across the roof and balconies to keep the residents of The Dunes warm and dry for many years to come.
SIKA PUTS WATERPROOF SEAL ON CHALLENGING UNIVERSITY REVAMP
Sika supplied the liquid-applied seal to help preserve the roofing detail at one of the UK’s hallowed university sites.
The roof refurbishment at Central Building - part of Cambridge University’s Fitzwilliam College campus - was one of the first projects to apply a pioneering approach. It included combining Sikalastic®-621; a highly-durable and elastic liquid polyurethane system, designed for areas with complex detailing, with Sika Sarnafil’s single-ply waterproof membrane.
Working closely with architect Cullinan Studio, contractors Gunite (Eastern) and Roofing Contractors Cambridge (RCC), and the college, Sika’s challenge was to create an appropriate waterproofing solution for the roof’s intricate design.
The original Central Building was constructed in 1963 by renowned architect Denys Lasdun. Its flat roof’s edge features protruding ‘scalloped’ detailing, hence the contractor’s potentially challenging requirement: waterproof the flat roof - which itself had plenty of challenging details – and the scalloped areas, whilst maintaining the look and integrity of the roof and the building as a whole. Concrete repairs were carried-out to the underside of the protruding scallops. Initially, this involved applying Sika® MonoTop®-610, a highperformance, polymer-modified primer, in lieu of high-build concrete repair mortar: Sika® MonoTop®-615. The steel reinforcement was protected with Sika® FerroGard®-903+. This penetrates the concrete and forms a protective monomolecular layer on the surface of the reinforcing steel, to prevent its corrosion. The concrete was finished with Sikagard®-550W, a high-performance anti-carbonation coating, with crack-bridging capabilities, that protects the concrete, whilst meeting the aesthetic requirements of the structure.
Dave Stewart, RCC Managing Director, said: “Due to the unusual shape of the scallops, it wasn’t aesthetically practical to install sheet membrane on them, so many, many discussions took place to decide how best to tackle this.
The Sikalastic® product ensured these unique details would be protected without altering their shape. It’s not unusual for a project to incorporate small amounts of Sikalastic, but this is one of the first projects where the Sarnafil membrane and Sikalastic®-621TC have been used over large areas together.”
For contractors, the crucial element of the project was ensuring the pinpoint precision of the seal. Working closely with Sika Sarnafil, RCC carried out multiple tests to ensure the junction between the Sikalastic®-621 and single-ply membrane was formed using the most effective detailing. The use of Sarnametal created a strong bond between the two products, enabling each to be successfully sealed.
Alex Abbey, Director at Cullinan Studio, who required the works to be sympathetic to the original building, said: “We needed a product that would not only effectively waterproof, but that would sit over the copper scallops and maintain the shape’s detail. Sikalastic®-621 proved ideal, and worked in harmony with the Sarnafil membrane, as did the Sikafloor®-420, which was used on the façade and underside of the scallops – a complete solution from Sika.”
It was thanks to the collaborative relationship between Sika Sarnafil’s technical experts, RCC’s highly experienced fitters and concrete repair contractor Gunite (Eastern), that the finished roof met the strict requirements of the architect and client.
Sikalastic®-621 - which features moisture-triggered chemistry and technology proven for more than 20 years – has played a huge part in ensuring the college building roof and its magnificent architectural features remain protected from the elements for many years to come.
