Frequently Asked Questions


Wherever water containment is needed, a watertight membrane is required to isolate the water from the surrounds & ensure that the containment material is leak free & compatible with storing the water in a safe & microbe free environment, whatever substrate it is collected on – precast or cast concrete, or whatever other substrate it is based on or in. Our Firestone EPDM membrane, being manufactured under controlled Factory conditions, presents the ideal, seamless, inert basis, either loose laid on a natural sand base, or fully adhered to the internal surface of a custombuilt water containment structure; 

Being manufactured under strictly controlled conditions & available in widths of up to 9m wide, 30m long & 1,14mm thick, it will be guaranteed to last many years, even in the most cruel Ultra-violet conditions – in fact, our Firestone EPDM carries a 15 year material warranty, backed by the manufacturer;  

On account of the fact that our EPDM is manufactured in 6m wide & 30m long rolls, together with a tried & tested sealing system &we are able to supply you with a 15year material, & 3year labour warranty;

Pursuant to the above information, this is not a problem  at all 

This is quite common with the older concrete farm dams, which we can remedy in either of two ways – Yes EPDM has in excess of 300% stetch capability with out affecting the quality.

It is our standard practice to terminate all EPDM upstands by physically fixing aluminium Termination Bars around the perimeter of our material, with alloy nail-ins, along the top of which we apply a bead of our Black Lap Sealant, as a final insurance that there will be no water ingress behind our material. 

Yes this is not a problem whatsoever.  Our products are fish friendly and U V resistance 

Another big benefit derived from using Waterproof Lab’s EPDM membrane, is the fact that it can be easily & quickly repaired by simply cutting a patch from a roll of our Quickseam Formflash (223mm wide), apply a coating of Quickprime to the damaged area, wait until touch dry & simply stick the patch down, making sure to roll it well with a rubber roller. ( The Formflash material is uncured EPDM & forms an integral bond with the membrane.) 

Our warranty is dependent on the fact that the installation of our EPDM system has been applied by an accredited Waterproof Lab/Firestone Applicator, which will entitle you to a 15 year material warranty & a 5year warranty from the responsible applicator  

 The advantage of our system over others, is that it has been designed by a World Class company, Firestone & tried & tested over a period of nearly 50 years, all over the world & in many countries world- wide, within differing climatic conditions, varying from the desert, with a high UV factor, to arctic conditions, many degrees below freezing.
