    Sustainable drainage systems (SUDS)

    Aco drainage system at the foot of the driveway which runs to a sump

    Ever since 1 October 2008 new rules have applied for householders wanting to hard surface over their front gardens. If the surface to be covered is more than five square metres, you will need planning permission for laying traditional, impermeable driveways that do not control rainwater running off onto roads. This will apply to new driveways, drive extensions or drive replacements. You will NOT need planning permission if the surface to be covered is less than five square metres or if the new surface is permeable or porous or if a traditional surface is laid and the rainwater is directed to a lawn or border to drain naturally or if it is directed to a soakaway via a drainage channel. An estimated 70% of existing driveways already drain in a sustainable way.

    From October 2008 we have advised customers to incorporate sustainable drainage into their pattern imprinted concrete projects to adhere to Sustainable drainage systems (SUDS) if their scheme doesn’t already conform with the SUDS protocol.

    This may be in the form of Aco drainage that flows into a sump or natural soakaway in the form of a border but there are other products which already conform to SUDS can be Resin bound aggregates and permeable block paving systems which are part of our range at Complete Driveway Designs.

    UK Concrete Show 2014

    UKConcreteShow

    Last year we told you about our involvement in the UK Concrete Show. We were not involved this year, which is probably why we forgot to tell you all about it!

    Like last year, the show took place at the NEC in Birmingham at the end of February, and again grew in size and scope. It was moved from Hall 17 to Hall 5, which is the largest indoor exhibition hall in the UK, and was for a long time the largest in Europe. This extra space was filled with 62 new exhibitors, 5 new in-hall demonstration areas, and all of the plant and equipment displays that had to be outside the previous year.

    Among the big names at the event were Putzmeister, Liebherr, Lafarge Tarmac, Husqvarna and CEMEX, covering all types of concrete materials and equipment, and demonstrations were done by Blastrac, Shotcrete and Adseal. In addition to the many global companies whose UK subsidiaries were at the show, almost 10% of the exhibitors were companies exhibiting in their own right from all round the world, including Denmark, Poland, the USA and China.

    Below you can view a short promotional video showing some of the events and exhibitions of this year’s show.

    Case Study – Queens Street, Padiham

    Padiham Pattern Imprinted Concrete

    Pattern imprinted concrete yard in Padiham

    This project was installed in September of this year. Originally a small space, this back yard was transformed into a more open and usable space using pattern imprinted concrete.

    Before the concrete was installed, a retaining wall was removed from the area and four steps were installed for access. The customer had previously had trouble with water seeping into his basement, so provisions were made for any water to run away from the house and into an aco channel which sat in front of the lowest step. An extra gully was also fitted to alleviate excess water from the roof of the outhouse.

    The pattern used for this yard is London Cobble, and the colour is Arizona Tan. As you can see from the above picture, even a relatively small space can be transformed into an attractive and functional part of the home.

    Mineral powders to reduce carbon emissions?

    Mineral powders

    We are always looking for more environmentally friendly ways to work, and a recent dissertation by Johanna Tikkanen of the Aalto University School of Engineering near Helsinki in Finland, could lead to big developments in the future.

    The idea of the paper was to study how different mineral powders could be used as replacements for the cement, the creation of which is one of the main contributors to the amount of CO2 emitted during the manufacturing process. Replacing or simply reducing the amount of cement in the concrete will lower the amount of CO2 used significantly, and will also reduce the cost of manufacturing. Mineral powders can also be used to reduce the water requirements of concrete, further adding to the economic and environmental benefits.

    Obviously, the properties of the cement will have to remain roughly the same, so that the concrete can be used in the same processes as before, but if it can be perfected, then concrete production will be greener than ever before.
