Graf

Graf is an international specialist in rainwater and stormwater management products. Their offerings include rainwater storage tanks (for harvesting systems) and subsurface crates for stormwater attenuation. For example, Graf’s EcoBloc soakaway crates are high-strength plastic modules that create underground water reservoirs. These “soakaway crates, also known as infiltration crates,” allow rainwater to “naturally soak into the ground, reducing the load on drainage systems”. Built from tough recycled materials with a 50-year design life, Graf’s infiltration tanks and crate systems are used in SuDS (sustainable drainage) to slow runoff, prevent flooding, and recharge groundwater.

Graf’s rainwater harvesting products include slimline and underground tanks, and filter units. The brand emphasizes longevity and environmental responsibility. For example, Graf states their crates are made from “quality material” for lasting use in homes and commercial sites. Their tanks and rainwater diverters enable collected rain to be used for irrigation or toilet flushing, reducing mains water demand. Overall, Graf’s ethos is avoiding pollution and caring for nature; their products provide robust attenuation and harvesting solutions that integrate with green building practices.
