HOW TO SPECIFY TRENCH/DRAIN COVERS

Often trench and drain covers fail because they are not specified properly for the application. Doing the job right, requires knowing two important factors specific to the application. First, measure the internal span of the drain. And second, estimate the maximum load the cover is going to experience during its operating life. Next, use the chart below to determine suitable thickness of the cover and reinforcement required. Note that since the chart below is prepared for solid covers increase the specifications if there are holes in the cover for drainage. More is the number of holes, greater would be the change to the specification. Lastly, ensure that the cover has a proper seating. The length of the seating can vary from 2 to 4 inches based on the application.

Konkrete Precast Concrete Products are manufactured using the latest vibro-compaction techniques, accurately designed moulds, appropriate reinforcement with circular plastic spacers and a concrete grade of M30 and above. In our constant endeavour to improve the products, the specifications may change without notice. All dimensions are in mm
