Our Completed Projects

“After successful completion of 2-No. retro-fit basements together to a Mews in SW7 which extended to below the road using a complex method not normally adopted for domestic dwellings we have now returned to site to complete the waterproofing allowing the follow-on trades to fit out these 2 desirable homes. ”


“Works have been completed at our site overlooking Wimbledon Park. The project included the construction of a 200 square metre basement with pool below an existing house and extension. The scheme was revised for top down techniques to allow the Main Contractor to safely continue refurbishment of the large detached property whilst our works took place. The project is now complete on time and on budget. ”


“The reinforced concrete structural shell has now been completed to the retro-fit basement in this quiet prestigious Wandsworth Street. Works were extended to allow for a larger basement terrace and below garden plantroom during our contract which was successfully carried out with minimal extension in time. ”


“We have achieved completion of the structural shell for a new build detached home in Putney.The basement stretches from boundary to boundary on each side and to the pavement line at the front making access and logistics the main concern, however the project has been completed 3 weeks early. ”


“We have completed the construction of the retro-fit basement below an end of terrace property in Fulham. This was carried out with a Fit-Out Contractor we enjoy working with who will go on to complete the fit out and hand the keys to the Client. Project completed in time and on budget.”


“We end the year completing 3-No. further projects this month in Hampstead, Oxford and Chiswick. We welcome our new additional team of waterproofing, enlarging our waterproofing team to 8, and congratulate Chris on his promotion to the role of Forman. Looking forward to 2015.”


“With a start of a new year and projects underway in Fulham, Bayswater, Holland Park, Finchley, Hampstead and Oxford. As ever our waterproofing teams are busy throughout London and the Home Counties. We are now entering our 15th year! With over 1000 projects completed!
Happy New Year toall our Clients, Engineers and Architects! ”


“We are beginning new projects in Fulham, St Johns Wood, Hammersmith and Putney. Our project in Bayswater is coming to an end again on budget. Holland Park is progressing well and we are now looking to adopt a top-down methodology for the remaining works. We are looking forward to starting works on a new 200 square metre basement for a block of flats in Fulham. The scheme involves piled retaining walls, underpinning, propping, bulk excavation and formation of RC basement shell, all of which we carry out reqularly on our projects.
Our Delta Cavity Membrane Teams are always very busy. We are now commissioning our installation of a deep 2 story, plus pool waterproofing in SW7. ”
