Allproof’s square drainage pits are highly adaptable and can be installed in commercial or residential projects.

The pits come in three sizes: 250 mm square × 300 mm deep, 350 mm square × 325 mm deep, or 350 mm square × 600 mm deep. The 350 mm square pits both come with pre-marked outlets and an easy-install rubber gasket pipe seal for Ø100 mm pipe. The 600 mm depth pit provides 300 mm depth at the bottom for sediment catchment.

All pit volumes range from 12 L–45 L. Grates have been designed to match or complement the grates from Allproof’s linear channel ranges, so design consistency can be achieved across all exterior drainage systems. Grates have been load-class tested for vehicle and foot traffic, with heelproof options available for pedestrian areas.

The 316 SS Wedge Wire grate has a slip resistance classification of R11/P2, making it the perfect solution for pavements and urban pedestrian areas. The tile insert grate provides a drainage path around the outside, meaning only a narrow reveal is visible. This solution is ideal for residential courtyards and patios but can also be incorporated into urban planning zones. For heavier traffic, the cast iron grate provides a commercial solution while still being heelproof.
