A proven all-rounder, mastic asphalt screed offers the versatility and speed of application that other more traditional cement screeds just can’t match. With deadlines, timelines and budgetary issues taking centre stage on projects, it’s important to know there’s a screed which is always up for the challenge. No matter what the application, a mastic asphalt screed will offer a stable and cost-effective base for all manner of waterproofing applications from green roofs to car parks.
Made from selected bitumens, limestone filler and specially graded aggregates, its flexibility and fast curing time enable the applicator to achieve precise falls quickly and more efficiently, level out uneven substrates and provide a stable base for a specified roofing deck system.
It’s designed for use on in-situ, pre-cast concrete bases, timber and plywood and is suitable for use below cold roofs, insulated warm roofs, inverted insulated roofs and all green roofs. Furthermore, it is a proven solution in balcony, terrace applications as well as walkways, footbridges and car park/HGV service decks. It can receive mastic asphalt, felt systems, hot melt, liquid coatings and single-ply roofing.
Busy building sites and inclement British weather may present an issue for some screeds, but in projects where a screed needs to be trafficked or overlaid quickly, mastic asphalt screed offers a rapid cooling process, a fast-track application and won’t impact on project timelines.
This is because mastic asphalt has zero water content, which eliminates the time taken for moisture to evaporate in traditional screeds. Also, there is no risk of cement stained water getting into the underlying structure. With the screed thickness itself up to 80% less than traditional materials, it is also much lighter than conventional materials and ideal for both refurbishments and new builds.
Available in three grades – light, medium and heavy – mastic asphalt screed can be supplied directly to site in purpose-built, hot-charge transporterscapable of holding 6 to 18 tonnes of material. As an alternative, it is also available in block form for re-melting on site.
When it comes to screeds, a contractor wants a solution that is reliable, simple to apply and is proven time and time again. Mastic Asphalt screed does just that and is the flexible, versatile all-rounder that has the performance to match.
