Slot Drain Installation

Strong, durable slot drain with an unobtrusive finish

Slotted Drain pipe removes sheet flow from streets, highways, and parking lots without multiple grades or water channeling devices. The result is an aesthetically pleasing inlet that is safer and easier to install and maintain. Our company Slot Drain Systems solved the issue of expensive installations, future workers health and maintenance wear and tear. Slot Drain Systems was the world’s first slotted trench drain solution that excluded traditional grates.

Gatic® Slot Drain handles everything from a raindrop to a rainstorm with almost the same high efficiency. Originally designed to meet the heavy demands of the world’s biggest ports and airports, this product has proven infinitely scalable and has been developed into a comprehensive range of products suitable for smaller projects such as landscaping schemes, shopping developments and parking facilities.

The unobtrusive design of Gatic’s slot drain means that it is aesthetically pleasing to the eye, is simple to install and benefits from reduced maintenance and installation costs.

Minimal visual impact

Slotdrain’s continuous intake slot is the only outward indication of the highly efficient surface water drainage system that lies just out of sight.

Easy & quick to install

Designed to keep below ground pipework to a minimum, thereby reducing installation time and both labour and materials costs.

Strong, durable & impact resistant

Initially designed to withstand the heavy demands of the world’s major airports and ports. This concept was then developed to suit smaller projects.

Comprehensive range

We supply a wide range of sizes and load bearing capacities making this product ideal for all kinds of applications, from residential, commercial and landscaping schemes to the most demanding of heavy industrial and transport projects.

Bespoke capability

If your project requirements can’t be achieved with our standard range of products or you have a particularly unusual problem to overcome, we can arrange the design and manufacture of custom components suit your needs.

Load rating from A15 to F900

Gatic Slotdrain channels are suitable for applications up to F900 (depending on the system type). The systems can handle everything from a raindrop to a rainstorm with similar efficiency.

Our range of products

Gatic Slotdrain comes in a comprehensive range to suit your specific requirements:

CastSlot

Designed specifically to meet the needs of supermarket car parks and delivery / distribution areas, where load ratings can reach F900.

The unobtrusive profile of CastSlot sits neatly within concrete, asphalt, and block surface finishes. CastSlot features an electro painted ductile iron throat section, which is securely fixed to the galvanised steel channel body to provide an exceptionally robust yet discreet drainage system. A treadsafe option is also available for areas where there is regular foot traffic. Available with a 10mm or 30mm opening. The NEW through spacer gives designers the flexibility to pass cables or other services through the channel throat as well as detail additional reinforcing for CastSlot and UltraSlot products. The new locking design ensures alignment and a tight fit prior to taping and pouring.

Load Classification: A15 to F900

Available channel widths:
High capacity surface water drainage
100mm, 150mm, 225mm, 300mm, 350mm, 400mm, 500mm, 600mm

UltraSlot

UltraSlot is used in external pavement areas which are subject to constant traffic, such as airports, ports and areas with heavy-duty vehicles.

The channel top edge has an outward fold for protection over the edge of the concrete encasement/surround, to prevent damage. Innovative channel features; concrete anchors, stabilising bars, channel feet and others, ensure the channel has a physical connection to steel reinforcing and is properly tied into the concrete encasement/surround, to create a strong, solid and durable structure.

A Treadsafe Bar can be fitted to the UltraSlot channel, which reduces the slot opening from 30mm wide to 2x9mm wide slots. This has no effect on the intake capacity of the system but will make the channel safe to cross when used in locations where pedestrians are walking over the pavement area. The NEW through spacer gives designers the flexibility to pass cables or other services through the channel throat as well as detail additional reinforcing for CastSlot and UltraSlot products. The new locking design ensures alignment and a tight fit prior to taping and pouring.

Load Classification: A15kN to F900kN

Available channel widths:
100mm, 150mm, 225mm, 300mm, 350mm, 400mm, 500mm, 600mm

PaveSlot

PaveSlot is used to drain external hard surface areas, where a neat, unobtrusive and aesthetic appearance is required. The system is typically used with paving units, laid against the top edge of the channel.

Contech Slot Drain Installation

Throat spacer perforations allow any subsurface water that may have settled under paving units, besides the channel, to percolate and move into the channel body. The system is suitable for all paved areas, in public and commercial projects, which may be subject to occasional traffic by delivery and service vehicles.

Load Classification:
A15kN to C250kN

Available channel widths:
100mm, 150mm, 225mm, 300mm, 350mm, 400mm, 500mm, 600mm

FacadeSlot

A discreet surface drainage channel that can be installed directly against a building, wall or other external landscape feature, to provide effective drainage of surface liquids from vertical surfaces, door thresholds and the adjacent pavement area.

FacadeSlot channels can be made to follow the building perimeter whether straight or curved. The system can accommodate rainwater downpipes which, when positioned over a simple rainwater inlet box, can eliminate the need for a separate drainage network for the roof area, achieving a more efficient drainage design.

Load Classification: A15 (Bespoke units can be made which are suitable for up to D400)

Available channel widths:
50mm, 75mm, 115mm

Swarm Aqua – Revolutionary slot drain

With a strong, durable ductile iron top section, this slot drain system combines steel side walls & Twinwall conduit to make it the perfect solution for all external drainage applications.

Slot Drain Installation

ACO Qmax – Versatile & robust

A versatile slot drain system that is designed to suit a wide range of applications, including small to large catchment areas as well as any load class. Another excellent slot drain choice.

NEW CONSTRUCTION

Slot Drain® is pre-sloped and fully assembled. It is easy to install, reducing labour costs and minimizing chances of error.

Drain sections arrive fully assembled and ready to install — no grating to screw on, no anchors or drains to weld, simply bolt the drain ends together, then pour your floor.

It takes two people approximately 20 to 30 minutes to install one 15 foot section.

1) Excavate a trench allowing for room underneath and on both sides of Slot Drain®. There should be a minimum of 6″ of concrete surrounding the drain.

2) It is recommended to pre-pour a concrete pad underneath the Slot Drain® pit so it can be properly secured. If no pad is poured, peg the sump pit down (using the flat bar mounting brackets bolted to the sides of the sump and wooden stakes) before Slot Drain® is connected.

3) Install all Slot Drain® pits and piping, making sure that the Slot Drain® pit walls are reinforced to prevent sidewall bowing.

4) Bolt the last (deepest) section of Slot Drain® to the Slot Drain® pit. If a Slot Drain® pit is not being used, start at the deepest section. Bolt all remaining sections of Slot Drain® together using the numbered flanges as a guide. For example, if you have a section 102, a section 203, a section 304 and a Slot Drain® pit. First, bolt flange 4 of section 304 to the Slot Drain® pit side marked 4. Next, bolt flange 3 of section 304 to flange 3 of section 203. Finally, bolt flange 2 of section 203 to flange 2 of section 102. Use a continuous bead of silicone sealant between all bolted sections.

Slot Drain Installation Detail

5) Use wooden stakes to set the desired elevation of drain sections. Secure drain sections to the stakes with the mounting holes provided on the levelling brackets.

6) Once Slot Drain® is secured and the appropriate elevation is achieved, for structural support, tie the rebar from the floor grid into the rebar/levelling bars on the drain assembly. Cover the opening with the duct tape, or insert Styrofoam if needed.

7) To ensure that Slot Drain® will not float, it is recommended that the concrete be poured in two stages. Once adequate time for the first concrete pour to set has elapsed, the floor slab can be completed. The use of a pencil vibrator is strongly recommended to make sure that the concrete has completely surrounded Slot Drain®, leaving no bubbles or voids.

8) Once the concrete slab is firm, first remove the tape or Styrofoam from the slot and then break out all metal tabs to ensure a continuous open slot. Using the paddle, clean out the Slot Drain®.

RETROFIT

Slot Drain® Systems arrives at the site in fully assembled sections and is ready to be installed.

1) Layout and mark drain location on existing slab.

2) Cut 24″ wide trench in existing slab.

3) Excavate the trench allowing for room underneath and on both sides of Slot Drain®.. There should be a minimum of 6″ of concrete surrounding the drain.

4) Drill and dowel into the sides of the existing cut slab. Approximately 16″– 24″ on both sides.

5) It is recommended to pre-pour a concrete pad underneath the Slot Drain® pit so it can be properly secured. If no pad is poured, peg the sump pit down (using the flat bar mounting brackets bolted to the sides of the sump and wooden stakes) before Slot Drain® is connected.

6) Install all Slot Drain® pits and piping, making sure that the Slot Drain® pit walls are reinforced to prevent sidewall bowing.

7) Bolt the last (deepest) section of Slot Drain® to the Slot Drain® pit. If a Slot Drain® pit is not being used, start at the deepest section. Bolt all remaining sections of Slot Drain® together using the numbered flanges as a guide. For example, if you have a section 102, a section 203, a section 304 and a Slot Drain® pit.

8) Use wooden stakes to set the desired elevation of drain sections. Secure drain sections to the stakes with the mounting holes provided on the levelling brackets.

9) Once Slot Drain® is secured and the appropriate elevation is achieved, for structural support, tie the rebar from the dowels and floor grid into the rebar/levelling bars on the drain assembly. Cover the opening with the duct tape, or insert Styrofoam if needed.

10) To ensure that Slot Drain® will not float, it is recommended that the concrete be poured in two stages. Once adequate time for the first concrete pour to set has elapsed, the floor slab can be completed. The use of a pencil vibrator is strongly recommended to make sure that the concrete has completely surrounded Slot Drain®., leaving no bubbles or voids.

11) Once the concrete slab is firm, first remove the tape or Styrofoam from the slot and then break out all metal tabs to ensure a continuous open slot. Using the paddle, clean out the Slot Drain®.
