A drain protector having a flexible adsorbent pad, a raised insert, and a cover is described. The pad and the insert each includes aligned apertures. The raised insert is positioned over the flexible adsorbent pad or within the aperture of the flexible adsorbent pad. The cover is connected to the flexible adsorbent pad, a raised insert, forming a space over the insert. The drain protector is made from adsorbent material for blocking sediment, collecting contaminants and filtering water into a drain. The cover of the drain protector reinforces the sheet and insert to protect against damage from traffic over the drain protector.

A method for filtering one or more of run-off fluid, chemical spills and facility discharge, the method including: storing a first portion of the one or more of run-off fluid, chemical spills and facility discharge in a first compartment; discharging additional fluid from an overflow in the first compartment when a volume capacity of the first compartment is full; in a second compartment in fluid communication with the first compartment, filtering the one or more of run-off fluid, chemical spills and facility discharge stored in the first compartment that is not discharged through the overflow, and discharging filtered fluid from the second compartment.

A drainage installation (20), for a warehouse and/or factory floor that has a surface level (26), has a drainage channel (24) recessed into the floor and a plurality of sections of flat grating (22) seated inside the drainage channel (24). The drainage channel (24) has an axially-elongated, square-U shaped channel portion which is flanked by horizontal shoulders (30), which then transition into vertically-depending skirt portions (32). The horizontal shoulders (30) as well as the sections of flat grating (22) are arranged to be more less planar with the surface level (26). Wherein, the skirt portions (32) are formed with a series of apertures (36) which either allow the injection of wet cement underneath the shoulder portions (30) of the drainage channel (24), or alternately the venting of the wet cement when the cavity under the shoulder portions (30) are over-filled.

A trench drain includes a trench, a grating seat and a grating hingedly connected to the trench. The trench has a base wall with peripheral side walls extending upwardly therefrom and an outwardly-extending peripheral flange. The grating seat is configured to receive the grating. The peripheral side walls of the trench have a pair of opposing elongated slots formed therein and the grating has a pair of posts on opposing ends thereof. Each of the pair of posts on the grating are received in a respective one of the pair of opposing elongated slots of the trench to establish an axis of rotation.

A drain assembly for installation in a shower floor, the drain assembly including a drain body including an upper surface defining a top side, and a lower surface opposite the upper surface defining a bottom side. The drain assembly also defines an aperture extending along an axis through the drain body between the upper surface and the lower surface and includes an outlet having a flange and an elongated body. When assembled, the elongated body is configured to extend below the lower surface of the drain body when the flange rests on the upper surface. The drain assembly also includes one or more fasteners configured to couple the outlet to the drain body to form a water-tight seal therebetween, where each of the one or more fasteners are accessible from the top side.
