STANDARD OPERATIONG PROCEDURE FOR RUBBLE SOLING

1. WORK DESCRIPTION Rubble Soling is a base structure of any foundation which is located under the Plain Cement Concrete of any type of Foundation like Footing, Raft, Road, Trimix, etc. general thickness of rubble soling is 230mm to 300mm. Rubble soling is done to prepare the uniform level surface on Hard Base or on backfilled surface to work clearly and above rubble soling PCC work will be done for plain level surface. If any level difference in base of the ground then we are doing plum concrete and rubble soling with the heap of rubble and PCC. If hard the surface level of any foundation is too deep and structure on this building in lightweight then needs to do rubble soling or plum concrete. Types of Rubble Soling      

Kata Soling Flat Soling Leveled Soling Random Rubble Soling Stone Pitching Plum Concrete

3. WHAT TO SEE? Following Drawings are needed to read to execute the rubble soling work at site.      

Foundation Layout Raft Layouts Foundation Sections Raft Section Level Drawing (For all types of a building) Plinth Level Drawing (For all types of the building)

4. WHERE WE USE! Rubble Soling will require to do at following locations         

Below Footing PCC Below Raft PCC Below Tremix Below WBM at Road Below Plinth Level PCC Below RCC Canal/Trench PCC Below Storm Water PCC Stone Pitching to Earthen Dam Stone Pitching for Road, Bridges embankments, etc.,

5. CHECK BEFORE WORK Standard Procedure of Work (Step by Step) Rubble Soling Work (Before Start the work)    

Calculate Approximate quantity of work Visit Nearest rubble stone quarry and check the quality of the material. Final the Stone which is must be basalt stone and needs to make with hand-packed or rock on rock technology. Order 1.5 times more material than you required. Because in a tractor-trolley if you ordered 1 brass Rubble, but it has more than 30% of voids, therefore, you need to order 1.5 times than the required material.

6. WORK PROCEDURE    

Study the Drawing of Foundation Layout Study the Drawing of Sections of plinth level Fix the 10mm or 12mm bar at 5m or 10m interval and mark all levels on it like Footing PCC Top, Bottom Level of PCC, Top Level of Rubble Soling, Bottom Level of Rubble Soling, etc. Compact all areas properly before starting the work. Don’t keep any loose material at rubble soling area. It must be compacted.

STANDARD OPERATIONG PROCEDURE FOR RUBBLE SOLING 





 

Shift the rubble stone near working place by the use of Labour, Tough rider, tractor, lorry or Labour, etc. Generally doesn’t use a wheelbarrow to shift the rubble stone because wheelbarrow will damage easily, it must then use it carefully. Start laying of stone as per your given standards, generally, all are preferred “kata Soling” Where we need to keep all the stone vertically places, and minimum gaps are kept between them and fix the small stone chips in the gaps of stones. Fix Line Dori to the marked bar at the top level of Rubble soling. And lay all the area as per the marking, if any stone height is more than your desired height then it should be cut by the hammer. Spread loose small and even good quality murum on rubble soling, fill all the gaps by chips and murum. If possible use a small plate compactor on it. Check your desired height after murum filling on rubble soling.

7. CHECKLIST Rubble Stone Soling Work Checklist is as Follows       

Check Stone Quality is Good or Not. Check the Level of Soling bottom and Top. Also, check the height of stone rubble soling work. Check Murum Quality. Check the gap filled by chips and Murum Check the type of Rubble stone soling Check if any stone is loose or not. If found loose remove it or fill the gaps by stone chips and murum. Check top-level is uniform or not.

8. EQUIPMENT       

Following Equipment is required to do rubble soling work. Tractor/Tough Rider Wheel barrow/Trolley Line Dori and 10mm or 12mm rod Chalk Auto Level and measuring Staff Hammer Plate Compactor

9. HOW TO MEASURE Rubble Soling Measurements are to be taken as per the following procedure    

Calculate the Area of Soling Check the Unit of BOQ which may be Square meter, Cubic meter, Sqft or Cubic feet. If Unit is Square meter or Sqft then only calculate length and width of soling completed area. if Unit in BOQ is mentioned as Cubic meter or Cubic feet, then need to measure the length and width of the soling completed area as well as read the item description where it may be written depth of soling is 230mm or 300mm.
