Slot Concrete - A Versatile One-Piece Drain System Slot concrete is a versatile one-piece drain system that has no grating and can replace trench drains. It’s especially suited to areas where grating is not desired or required, such as food and drink processing facilities, airports, parkades, warehouses and truck loading docks.

It can be installed in slab on grade applications or structural slabs. It’s sanitary and has been shown to be more durable than any other surface drainage system on the market.

Suitable For The Following Application: - Areas with heavy traffic / high volume / frequent cleaning requirements such as airports, parkades, warehouses, truck and rail loading docks etc. - Areas where grating is not desirable such as areas subject to severe weather conditions or soil contaminates that would deteriorate / break / bend a traditional drain. gboslot

A key benefit of this system is the ability to have a linear slot in the drain that can easily be cleaned without any special equipment. This makes it a perfect drainage system for areas that require constant inspection and cleaning such as food and drink processing facilities.

The process of slot concrete is not new and has been around for years. It’s a popular alternative to trench drains and is a highly cost-effective way to provide durable, sanitary, self-cleaning floor and ground surface drainage.

It’s important to consider all of the details that are involved in slot concrete when selecting a drainage solution for your project. These include the type of pavement, any existing drainage system, the amount of fluid that will be able to flow through the slots and any contaminated soils or groundwater in the area.

To prepare the surface for slot drainage, a maximum weight 30 pound jackhammer should be used to remove any concrete that may have accumulated in the slots between the saw cuts and clean out any debris.

Once the surface has been prepared, place the dowel bar in each slot. Bond breaker must be applied to the dowel bars as per specifications. Expansion caps are also placed at each end of the dowel bars and dowel bar support chairs are used to firmly hold the dowel bars in place during backfill operations.

In addition to the dowels, a foam core insert should be inserted in each slot to allow the joint or crack to expand and contract as needed and provide a good anchoring action for the bar within the slot. The backfill material should not be compacted too deeply or too much so as not to cause the bar in the slot to become loose.

After the dowel bar is in place, apply caulking filler to the slot. This allows the backfill to flow and consolidate under the dowel bars. The dowel bar should be positioned at mid-depth in the concrete pavement slab and centered on the wheel path.

The dowels are then re-placed in the slots and non-shrink concrete backfill material is placed and the job is finished. This method is an excellent option for repairing roadways that are deteriorated or have lost their load transfer and can be completed in a day or two with minimal impact to traffic.
