DELTA MEMBRANES

FIRE RETARDANT , TYPE C WATERPROOFING MEMBRANES

PAYING ATTENTION TO WATERPROOFING PRODUCTS WHICH OFFER PROTECTION IN EVENT OF FIRE IS NOT THE NORM . WE HARDLY THINK OF WATER MANAGEMENT AND FIRE IN THE SAME THOUGHT , HOWEVER THE BENEFITS OF DOING SO ARE NOT QUITE AS CRAZY AS IT SOUNDS
In an age where prevention to fire is rightly under scrutiny in the construction industry , thoughts should be given to specifying materials which have properties which not only reduce the risk to occupants ’ safety , but also have a lesser reaction time in the event of fire .
With Delta MS 500 Fire Retardant membrane it is now possible to specify a Type C , cavity drainage membrane that offers not only protection from water or vapour ingress but also protection in the event of fire .
When designing the most appropriate waterproofing system to any given situation , various design factors will need addressing such as ( but not limited to ), final use of the building , the grade of waterproofing requirement under the British Standard , structural considerations based on the form of construction , ground conditions , and in some cases , satisfying the requirements of building warranty providers .
Important considerations should be given when designing a basement or below ground structure on how it will behave during the event of fire . Whilst a basement is not counted when assessing the numbers of storeys of a property for fire resistance and means of escape , it should be factored into design and be a key consideration .

structure on how it will behave during the event of fire .
One of the challenges faced when designing a suitable waterproofing system has been compartmentalization of separate units in a single basement space . This can cause challenges from a waterproofing design perspective in maintaining continuity of the system . Using a fire-retardant membrane system enables the waterproofing designer to keep the waterproofing system continuous between adjoining basement properties whilst dealing with the issue of spread of flame from one property to another .
Delta ’ s new fire-retardant Type C Cavity Drainage System with a fire classification of B-s2 , d0 , provides architectural freedom and allows systems to be used in not only deep basements but where Building Regulation Euroclass B or C are needed , meeting building requirements of today , but also that of tomorrow .
