Crumlin Bridge Protected with Spray Applied Waterproofing

A waterproofing solution to aid project completion

The specifier selected ELIMINATOR^®, which is based on unique ESSELAC^® technology, as well as Bond Coat 3, a cold reactive resin system providing a durable, protective finish, resistant to site damage with unlimited open time prior to application of the surfacing..

Prior to application, shot blasting and fine milling was carried out, with the METASET^® concrete system being used to repair rough and damaged areas of the bridge deck in preparation to receive the waterproofing system. The deck was primed to seal the deck and promote excellent bond between the deck and the membrane

The ELIMINATOR^® membrane was then cold spray-applied and checked using a wet film gauge to confirm the required coverage and thickness had been achieved. Once the waterproofing membrane had been applied and left approximately 30 minutes to cure, it was electrically integrity tested (holiday detection test) to confirm that a defect-free, fully waterproof barrier had been achieved.

Bond Coat 3 was then spray-applied. The durability and unlimited open time of Bond Coat 3, allowed flexibility in the schedule and the following trades to proceed in compliance with the programme of works without unnecessary delays, saving time, money and further disruption. Due to the success of the project on the first 1150 metres of carriageway, the second phase of the project went ahead as planned completing the refurbishment of the Crumlin Bridge.
