BAL Waterproof 1C – the one-coat ready-mixed waterproofing system from the market-leaders in tiling solutions – has received EAD certification for use on NHBC-approved housebuilding sites.
From January 1st 2025, NHBC the UK’s leading provider of warranty and insurance for new homes in the UK implemented new requirements for their members.
This will mean that any new house in the UK that is built (foundations laid from 1st January 2025) will require tiling in wet areas to be tanked with an EAD certified system to receive warranty and insurance, if they are tiling:
- Shower over bath OR shower with shower tray, with standard flow rate <12 litres/min – WHEN the substrate manufacturer’s guidance advises a tanking system is still required, or has not passed NHBC Table 2 assessment requirements.
- ANY shower over bath OR shower with shower tray, with a flow rate >12 litres/min.
- ANY wet room (fully tiled wall and floor, shower area).
To remain compliant, only suitable NHBC accepted products which form a watertight covering for walls and floors should be used.
BAL Waterproof 1C has been rigorously tested and adheres to all NHBC regulations, crucially receiving EAD certification ETA 24/1129 to comply with NHBC specified standard EAD 030352-00-0503.
The product offers a number of benefits over other EAD-certified waterproofing systems and is also certified with a full BAL tiling solution as part of EAD testing requirements.
BAL Waterproof 1C is a cost-effective ready-mixed solution – which means no additional mixing is needed on site – and can be used on most common substrates without priming*.
It is ready to tile after only 2 hours, meaning jobs can be completed sooner.
Formulated with fibre-strand technology for improved strength, it can be applied in one-coat on walls (ensuring 0.8mm thickness) and floors (ensuring 1.6mm thickness) with a brush, roller or 4mm notched trowel.
This innovative new product is lightweight with easy-to-apply rheology and provides excellent coverage of up to 6m² – making it suitable for a standard domestic shower room, bathrooms or wetrooms.
BAL Waterproof 1C also has sustainable benefits with Low VOC and using 40% recycled materials.
As part of the EAD requirements, BAL Waterproof 1C Tape and BAL Waterproof 1C Matting (when tiling direct to the floor) are necessary, plus BAL Universal Sealant and Adhesive – these are now available from BAL.
EAD certification also requires the use of specific approved tile adhesives with each approved EAD waterproofing system. BAL has multiple options from their existing core range of adhesives that can be used with BAL Waterproof 1C.
John Stewart, UK Sales Manager for Offsite, Housing and Marine, said:
“The latest NHBC guidance puts the emphasis on housebuilders and developers to ensure that showers, bathrooms and wetrooms are adequately waterproofed with an EAD approved system.
“BAL Waterproof 1C provides an easy and cost-effective solution to ensure tiled wet areas are compliant with the new NHBC standards.
“BAL Waterproof 1C applied as one coat with a minimum 0.8mm dry thickness on walls – provides complete protection against water ingress, protecting backgrounds from water damage and erosion.
“As a ready-mixed, fast-track solution, it is easy to apply on site and ensures that tiling can be commenced the same day.”
