Hull City refurbishment project covered by Dryseal

// the building envelope

This project started as a trial for Hull City council on an outhouse joining a pair of houses in Cropton Road, Hull. The Council’s Housing Department was considering several waterproofing systems for covering roofs on a potential scheme to upgrade post-war Wimpey ‘no fines’ concrete houses, and Dryseal, due to its aesthetics, excellent detailing capabilities and tough, durable finish, was deemed to fit the bill.

As the project progressed, the brief was extended from simply installing Dryseal in a ‘cold’ configuration on the outhouse roofs to include porch/canopy and annexe ‘warm’ roofs, doubling the roof numbers.

Andy Fell Hambleside Danelaw’s Dryseal Manager said “The standard of installation and finishing delivered by L A Hall’s operatives is exceptional, resulting in very robust and aesthetically pleasing roofs.”

The external concrete walls were upgraded to current Building Regulation Part L standards, the main house roofs recovered with a new insulated Decra lightweight tile specification and all the ‘flat’ roofs refurbished using Dryseal.

Steve Copeman, Managing Director of LA Hall (Hull) Ltd, said: “Having worked closely with Andy Fell on the prototype a couple of years ago it was clear from the start that everyone was happy with the finish we could achieve with the Dryseal system. Not only did it give the desired look it also gave a level of durability the roofs needed. We have completed the roofing works on several different types of ‘non-standard’ properties and then as Dryseal works progressed it became clear to our Client that the system is suitable to cover other sections of low roofs on certain house types which were originally going to be covered with composite insulated panels. This allowed us to achieve uniformity to the scheme that the Client didn’t originally think was possible. We will end up completing over 230 roofs using Dryseal.”

The development of the specification from one 20 m2 roof to an are totalling 2,300 m2 is testament to Dryseal’s quality along with the excellent work by L A Hall.

The whole project is covered by 20 year guarantees for each property.
