Water Tower Liquid Roofing Norfolk


Years of neglect had lead to water ingress and spalling of the concrete. Water was now entering the pump room below risking significant damage to plant and equipment.


We proposed the application of a seamless liquid waterproofing system to prevent future water ingress.

Initially all defective areas of concrete were broken out using vibration damped breakers. The exposed steel reinforcing was prepared to ST3 using chippings hammers and needle guns. All exposed steels were primed using Corroless EPF Rust stabilsing epoxy primer and a quartz aggregate scattered into the wet resin to promote adhesion of the subsequent concrete repairs.

Repairing the concrete using Remmers Beftofix RM

Once prepared concrete repairs were undertaken using Remmers Beftofix RM. The benefit of this product is that it can be taken to a feather edge, significantly reducing cutting and breaking operations that would expose our applicators to additional hand arm vibration.

All surfaces to which the liquid roofing system was to be applied were prepared by either vacuum controlled scarifying or diamond grinding. The liquid roofing system that we had specified was specifically selected for its compatibility with old bitumen systems, so that it was not necessary to remove all of the old coatings where they were firmly adhered.

Priming with Remmers Kiesol

The exposed concrete was then primed with Remmers Kiesol to consolidate and penetrate the concrete. Following priming all cracks and the perimeter received an additional stripe coat of Remmers MB2K incorporating a reinforcing bandage.

Remmers MB2K was then applied in three coats by method of slurry brush to a thickness of 3mm. This material is highly elastomeric and can crack bridge to a width of 2mm.
