Add-A-Step Modular Ladder System
Add-A-Step Modular Ladder System Add-A-Step is a modular manhole ladder system that replaces traditional galvanised and stainless steel access ladders — at lower cost and with faster, safer installation. Fully compliant with BS EN 14396 and Sewers for Adoption 7th & 8th Edition, it’s approved for potable water, wastewater, highly corrosive and general construction environments, and is already the first-choice manhole ladder for several major UK water utilities. Because it’s modular, ladders can be built to exact chamber depths on site and individual components replaced without removing the whole ladder. R&B is the sole UK distributor — contact us for specification support or utility approval documentation.

slow-moving traffic — hospitals, food manufacturing facilities, retail and public realm schemes — where drainage performance, hygiene
and appearance all matter.

Every grating is made to order in the UK, so openings, bar spacing, load requirements and locking options can be tailored to the project. Send us your drawings or dimensions for a fast quotation.

Drain Defender - Gully Protection
Drain Defender - Gully Protection Drain Defender is a reusable gully protection insert that stops silt, sediment and construction debris entering the gully pot — protecting connected drains and sewers downstream. On developments with unmade roads, gullies quickly silt up, leading to blockages, flooding and costly cleansing before adoption. Drain Defender installs in seconds, is lifted out and emptied as needed, and dramatically reduces gully emptying and jetting costs across the life of a site. Proven on major housebuilder and civil engineering sites nationwide — see our case studies.

Duct Access Chambers
Duct Access Chambers Polypropylene duct access chambers developed with a UK manufacturer for power, telecoms, fibre and drainage networks. Lightweight sections make installation fast without lifting equipment, while the finished chamber withstands demanding highway and construction loadings. Available in a range of plan sizes and build heights to suit project specifications, and compatible with our ductile iron and fabricated cover ranges for a complete, single-source access solution. Used on schemes from urban infrastructure to major port developments.
