A tile drain and method of installing a tile drain is provided. The tile drain includes a drain body and a drain cover. The drain body defines a top opening, top weep apertures, and bottom weep apertures. The top opening receives the drain cover and serves as the primary drain for the tile drain. The top weep apertures are positioned below a top layer, such as a tile layer, of the base so as to receive fluid positioned between the top layer and a top waterproofing layer of the base. The sub weep apertures are positioned below the top waterproofing layer of the base so as to receive fluid positioned between the top waterproofing layer and a bottom waterproofing layer of the base. The drain body is encapsulated within the base, but the drain cover is adjustable relative to, and removable from, the drain body.

A flexible modular trench includes an open-faced channel extending along a central axis between a pair of axial ends. The open-faced channel includes a pair of axially-extending shelves connected by a trench wall. The trench wall has a smooth inner surface and a corrugated outer surface. The corrugated outer surface has corrugations extending along a plane perpendicular to the central axis to allow for increased flexibility such that the flexible modular trench is bendable in a direction perpendicular to the central axis.

The subject of the application relates generally to the field of drainage elements, typically drainage channels, and covers thereof, as well as mixtures for production of such covers. Embodiments may include drainage element covers, meeting functional (water permeability, slip resistance, abrasion resistance, hygienic safety, strength, resistance to frost, etc.) as well as aesthetic requirements, and which would be suitable for applications in exteriors as well as interiors, and further propose a mixture for production of such drainage element covers. Functional and aesthetic requirements may be achieved by means of a mixture for producing drainage element covers, comprising aggregate and/or milled glass pulp and binder, and further comprising thixotropic additive.

A stable and variable design of a drainage structure includes a drainage body (11) and a cover (20). The cover (20) has engagement devices (13, 13′; 14, 14′; 23, 23′) when seen in a longitudinal direction of the drainage body (11), whereby the cover connects upper edges (12, 12′) of the drainage body (11) to one another transversely to the longitudinal direction in a tension-resistant manner over the entire length of the drainage body. In order to allow the use of different covers (20) for different loads, for example while using the same drainage body (11), two types of engagement devices (13, 13′; 14, 14′) are provided on the drainage body.

In one representative embodiment, a trench drain comprises first and second end portions, a channel portion extending longitudinally from the first end portion to the second end portion, a continuous, unobstructed slot portion extending from and in fluidic communication with the channel portion, wherein the slot portion and the channel portion form an internal flow passage, and at least one gusset coupled to the slot portion and the channel portion and disposed external to the internal flow passage.

Rails for drainage channels or manholes are known on which a cover of a channel or of a manhole can be placed. The rail has a horizontal bearing surface (10) extending in a longitudinal direction of the drainage channel or of the manhole and, substantially perpendicular to this bearing face, a rail edge (11) on the inner surface (12) of which the cover can be placed and on the outer surface (13) of which a surface covering can be applied. To increase the strength, it is proposed that the bearing surface (10) and/or the inner surface (12) and/or the outer surface (13) is/are provided with beads (20, 22, 23) over the entire length of the rail (1).

A linear drain assembly is provided. The linear drain assembly includes a base portion and a first peripheral portion. The base portion includes a base trough and a base flange. The first peripheral portion includes a first trough and a first flange. The first trough is nested within the base trough and the base flange is nested within the first flange.

Embodiments of the invention are directed to a trench former assembly and a method of constructing a trench using the trench former assembly. Typically, the trench former assembly comprises a forming member and a corresponding retention and removal system. The forming member is structured to facilitate forming the trench, while the retention and removal system is structured to suspend the forming member and support the forming member against displacement and rotation during forming of the trench. Embodiments of the invention are also directed to a dual-pour type trench former assembly for forming a multi-layer trench.

The invention is broadly directed to a drainage channel and grate assembly 10 comprising a plurality of drainage channels 12a and 12b and a plurality of drainage grates 14a to 14c. The drainage channels 12a/b join one another at a channel junction 16ab in an end to end relationship. The drainage grates 14a to 14c are also arranged in an end to end relationship and are connected to either one or both of the drainage channels 12a/b. One of the plurality of drainage grates 14b bridges the channel junction 16ab to support the drainage channel and grate assembly 10 at set junction 16ab.

Embodiments of a drain comprise three primary components that can be provided in a preassembled configuration: a drain body, which includes an integral upper flange; a lower clamping collar that forms a lower flange; and a waterproof membrane that is fixedly sandwiched between the upper and lower flanges and extends outwardly therefrom. The drain is further characterized through the use of a plurality of fins that extend into the cylindrical interior of the drain body's throat and act to position and hold a drain cover assembly in place replacing the use of threads that are common in the prior art.
