Valley - Amsterdam

Valley - Amsterdam

Knauf Insulation bv

Valley is a place where people will soon live, work and enjoy city life. In the heart of Amsterdam's Zuidas district, a mix of offices, a cultural exhibition space, shops, parking facilities and flats is rising up. Valley is a new form of urban living that combines the best of two worlds: city life and natural surroundings. Heraklith and Knauf Insulation were able to contribute to these high-quality buildings in various places.Challenge.When designing Valley in Amsterdam, the focus was on sustainability, comfortable living and working. It was a requirement of the client that all materials should score highly on sustainability. The people who work, live or visit there must feel very comfortable.Create.The solution was found in Heraklith wood wool combi panels and the Naturoll 032 from Knauf Insulation. The Heratekta & Herafoam wood wool boards were used as thermal and fire insulation (Euro fire class B). The Naturoll 032 glass wool insulation is made with ECOSE Technology, a natural binder which contributes to the sustainable character of the building.Care.Specifically for projects in busy city centres or in locations with little storage, it is possible to agree a delivery schedule.

Essex University - The Pastures

Essex University - The Pastures

RCM - Roofing and Cladding Materials Ltd

The campus in Colchester, which is home to 15,000 students, is undergoing a massive phased transformation. Benx-RCM are currently supplying into phase three of the campus-build, known as The Pastures.Split across five new buildings, The Pastures will bring an additional 1,262 student bedrooms to the Colchester campus. One of these blocks will create a new hub which will include a reception, a post room, an administrative area and a student services centre, along with a laundrette and staff welfare facilities.Overseeing this £168 million project as main contactor is Bouygues Construction.Stanta were awarded the SFS infill package at the site. As part of this package, Benx RCM were selected to supply Y-Wall external sheathing board for the entire project.Y-Wall is a flexible calcium silicate based fibre cement building board, offering excellent fire properties as well as high levels of dimensional stability. The Y-Wall BBA Certification provided the Stanta project team with assurance that this building board solution has been tested to exacting standards, evaluated onsite, as well as undergoing a life expectancy assessment and a quality management system review.Y-Wall was utilised to create a sheathing for the five high rise structures. In buildings with storeys more than 18m above ground level, any products used in the external wall construction should be of limited combustibility. Being a non-combustible, A1 fire-rated building board, utilising BS EN ISO 1182 and BS EN ISO 1716 tests, Y-Wall is the optimum solution for a project of this type and size.In specifying the building board for this project it was important to ensure the optimum racking performance to enhance structural strength. Y-Wall conforms to European Norm - BS EN 594:2011 - the certification which proves the system has been rigorously tested and offers excellent racking performance, structural strength and stability.Specifying a building board that is fully tested to BS EN 1062-1 allows for adequate moisture resistance and durability. Y-Wall fully complies with this standard which ensures the building boards will have a life equal to that of the building. Selecting a building board with good external performance and durability is important, particularly through the build phase, as the product may be left exposed for several months prior to a secondary facade being installed over the top of the system. In order to generate speed and ease of construction, Y-Wall was supplied pre-cut to specified panel sizes. The fabrication work was undertaken by Benx Façades at its dedicated facility, to ensure a seamless process.

Cement based floor screed solution for underfloor heating

Cement based floor screed solution for underfloor heating

Tarmac

A new flooring solution was required as part of a large, high-specification selfbuild housing project on the stunning Archerfield estate in North Berwick. Underfloor heating had been specified for the ground floor of the house and it was important that the chosen floor solution would help to optimise heating efficiency. Given the scale of the project it was also important that the chosen screed solution could be installed quickly over a large area to fit within the build programme. Following initial discussions and a successful pump trial the customer decided to use Tarmac’s TOPFLOW Screed C cement based liquid screed.TOPFLOW Screed C is a free-flowing, cement based liquid screed that can be trafficked after just 24-48 hours and dries within 21-28 days. It can be pumped into place and allows large areas to be covered quickly with up to 120m2 laid in as little as 45 minutes. Fast drying times mean it can be laid later in the programme when the building is fully water-tight and still hit deadlines for installation of flooring. It is ideal for use with underfloor heating systems. As a self-compacting screed, it fully encapsulates heating pipes without leaving any voids and is also a more conductive medium than traditional sand and cement screeds, improving the thermal performance of the system. It is also compatible with most cement based adhesives meaning it can be used with a wide range of flooring types.The fast-drying times and early trafficking characteristics of TOPFLOW Screed C enabled other trades to follow on quickly, helping to provide continuity and efficiency within the client’s build programme. The contractor was delighted with the outcome, commenting on how good the material was to work with and on the excellent finish achieved.

HP11 Austrey, Barston Gas Pipeline Diversion

HP11 Austrey, Barston Gas Pipeline Diversion

PUDLO Waterproof Systems & Cemfree Zero-Cement Concrete, part of the DB Group Ltd

Cadent Gas require to divert the existing high pressure gas pipeline at Austrey to Shrewley to provide mitigation from external loading from future HS2 traffic. As well as standard trench construction the diversion also compromises tunnelling at certain locations along the route.To launch and receive the tunnel boring machine (TBM) a secant piled shaft is constructed at the launch and reception sites.Secant piled shafts are constructed with bored piles and typically compromise overlapping primary/soft and secondary/hard piles. Primary/soft piles are formed without reinforcement from a weak bentonite slurry to low strength concrete typically C8/10 with secondary/hard piles installed with reinforcement and using structural concrete typically at C30/37 or higher and cutting into the primary/soft piles to form an overlap which prevents water and fines entering an excavation. Secant pile shaft structures for TBM works are typically temporary works designs with less onerous full design life/durability criteria. The selection of the soft/primary pile concrete mix is critical to achieve the correct balance of structural performance and durability where required without impeding the installation of the secondary/hard piles. As very stringent installation tolerances are needed the strength gain profile of the primary/soft pile concrete mix is also required to be clearly understood to calculate the timings of the secondary/hard pile installation.It is a priority for us to find the latest technology to minimise our impact on the environment. As a result, we were keen to approach DB Group to consider how we could use cement-free concrete on one of our projects. This is where Cemfree comes in. It is an ultra-low carbon alternative to standard concrete whereby OPC is replaced with novel alkali activated cementitious material (AACM). As it does not contain any OPC, it can save up to 88% of CO2 emissions on a project.Cemfree has been used in the UK since 2010. However, so far it has only been used on small scale projects. Therefore, we have partnered with DB Group, Hanson and BRE to trial Cemfree concrete on the primary/soft piles for the secant shaft piling at our HP11 gas main diversion project and better understand and develop its characteristics for future use in piled structures.

Sustainable construction is at the heart of what Greencore does, but delivering a truly sustainable home always presented one obstacle – the concrete in the foundations and slabs that these bespoke properties were being constructed on – as they remained the only elements of the construction heavily saturated with embodied carbon.
Use of Cemfree concrete for temporary slab piles at Newman St, Westminster

Use of Cemfree concrete for temporary slab piles at Newman St, Westminster

PUDLO Waterproof Systems & Cemfree Zero-Cement Concrete, part of the DB Group Ltd

Murphy Ground Engineering installed 750mmand 880mm cased rotary piles up to 34.0m toform a triple storey basement secant wall andbearing piles for a new Hotel development inWestminster. As part of the top downconstruction methodology and due to limitedperipheral space, a temporary slab wasdesigned to accommodate construction plantduring the bulk dig and spoil removal.Due to the loadings on the temporary slab the design required 6# 880mm piles to 25.0m depth to provide support to the slab. As these piles are temporary works in design the use of Cemfree concrete was proposed, although with specific structural requirements it was imperative for the Cemfree concrete to achieve 40N strength at 56 days as well as perform to the required piling concrete characteristics as would be expected. A total of 95m3 of “C32/40” Cemfree concrete was supplied over a period of 4 days to construct the temporary works piles using temp cased rotary bored methodology.The use of Cemfree at Newman St was aligned with MGE involvement in the LOCOWAG project led by DB Group (Holdings) Limited (DBG). The project is government funded via the Innovate UK scheme and runs from November 2020 to November 2022.
