Our early contractor involvement and pre-programming of work has helped Dandara Ltd effectively deliver the tanking and concrete liner wall requirement to face the 1100m² of contiguous piles on their prestigious scheme to provide high value residential apartments for academics in the city
This project involved the filling out of any extensive voids between the piles with concrete then lining the 1100m² of contiguous piling and pile cap in Voltex, a highly effective waterproofing composite of high strength geotextile and 4.88 kg of sodium bentonite per square metre. The high swelling, low permeable sodium bentonite is encapsulated between a non-woven and woven geotextile providing a monolithic waterproofing membrane once the geotextiles surface fibres of the product are encapsulated in concrete. We then drilled over 2500 anchor points into the piles to fix the steel fabric and set them with resin and applied a 150mm layer of sprayed concrete to the face of the piles to complete the job.
The site is located on one of the main access routes into the city centre which made the logistics onsite extremely challenging. With the piles being over 9 meters high, our engagement and collaboration with the excellently managed site team meant that we were able to deliver the work in under 6 weeks, two to three times faster than the traditional shuttered and poured method of concreting.
Programming, technical compliance and site logistics, ensured the successful delivery of the project.
