Apex-Self-Storage

LOCATION

Roof area 800m2

WATERPROOF SYSTEM

System 20SLF and System 10 underlay

BACKGROUND

Apex Self Storage had acquired the previous GUS office block in Ardwick, Manchester, and converted it to self-storage units. The existing single ply membrane roof covering was becoming aged, brittle and starting to fail. Water ingress had become evident and required attention to ensure weathertight  protection of the storage units.

The Challenge

The site required access to the building to be unhindered whilst the work was carried out. The confined paved area needed to remain open to use by large goods vehicles carrying out deliveries and collections as well as to members of the public who had storage there.

With access being difficult the decision was made to encapsulate the existing system, which while starting to fail hadn’t led to the damage and saturation of the insulation. This meant that the required waterproofing system needed to be compatible with the current covering, be a single layer material, and come with a twenty year guarantee.

Project solution

Our System 20SLF is a fleece backed SBS membrane which can be either mechanically fixed or fully adhered with heat sealed laps. It can be used as a flame free system and is also suitable to overlay existing single ply membranes.

The specification for this project was to clean and prepare the existing surface, release the tension in the existing PVC layer by slitting along the perimeter, overlay this with a geotextile fleece layer, then install System 20SLF, mechanically fixed.  Our Lancastria System 10 underlay was also applied to the perimeter details and fully bonded by torching.

The whole new overlay system was successfully installed with minimum disturbance to the building occupants and with no ime delay.

The contractor Starfish 9 Ltd was delighted with the outcome; “We’ve not used this system before but everything went well with the job. Lancastria’s System 20SLFB is an excellent system to use and all deliveries arrived on time.”
