Building Material in Tenkasi
Gravel (Saral) and Kundu Kal
TKR Building Materials supplies gravel, known locally as saral or saral kraval, and kundu kal, the rounded stone used under foundations, across Tenkasi district. Gravel is the standard material for filling and compacting the plinth, basement and floor beds before concrete. Kundu kal is packed as a soling layer below footings and plain concrete so the load spreads onto firm ground. Both are sold per unit and delivered by tipper from our yard at Ilanji.
- Gravel for plinth, basement and floor-bed filling
- Kundu kal for foundation soling and rubble packing
- Clean, well-draining material that compacts firmly
- Combined loads with blue metal and M-Sand
What gravel (saral) is used for
Saral is a natural gravelly soil with a mix of small stones and coarse sand. It is laid in layers inside the plinth and basement, watered and compacted to form a stable, well-drained base for the floor concrete. Because it does not hold water like clay, it reduces settlement and dampness in the floor. A typical house in Tenkasi needs several units of gravel to raise the floor level to plinth height.
What kundu kal is used for
Kundu kal are rounded stones, usually 100 to 150 mm, laid as a packed soling course under footings, plinth beams and plain cement concrete beds. The stones are hand-packed tightly, the gaps filled with gravel or sand, then rammed. Soling spreads the load over soft or filled ground and gives a firm, level base for the concrete above. Engineers specify it on most sites in the district where the ground near tanks and fields is not hard rock.
How much do you need?
Gravel: multiply the plinth area by the depth of fill, add 20 to 25% for compaction and divide by 100 to get units. Kundu kal: the soling area in square feet multiplied by the soling thickness in feet, usually 0.5 to 0.75 ft, divided by 100. Share your plan and plinth height and we will work out the units and schedule the trips so filling does not stall the site.
