Thrust blocks must be constructed so the bearing surface is in direct line with the major force created by the pipe or fitting. See diagram. The earth bearing surface should be undisturbed (virgin wall).
2. Thrust blocking is to prevent the line from moving when the pressure load is applied, transferring the load from the pipe to a wide load bearing surface.
Thrust blocks are required where fittings are used to change direction (i.e.
the following but not limited to; all tees, elbows, wyes, caps, valves and reducers etc.) of the pipe line. The thrust blocking must be formed against a solid trench wall (virgin wall) and these fitting areas must be excavated by hand, mechanical equipment will damage the bearing surface of the trench wall.
3. The size and type of thrust depends on pipe size, line pressure, type of fitting, degree of bend and type of soil. Thrust block size may be calculated by the example procedures shown below.
4. It will be the responsibility of the Contractor for all change of direction thrust blocks on all size piping. Furthermore, the warranty period for pipe and/or fitting failures is for (2) years from the date of acceptance.
Step 1 – Multiply the pressure level desired for testing by the appropriate value shown in the following table:

Step 2 – Determine the bearing strength of the soil from the table below:
Bearing Strength of Soils
Soils and Safe Bearing Loads Lbs. Sq. Ft.
Sound Shale 10,000
Cemented Gravel and 4,000
Sand-difficult to pick
Coarse & Fine 3,000
Compact Sand
Medium Clay - 2,000
Can be spaded
Soft Clay 1,000
Muck 0
Step 3 – Divide the total thrust obtained in Step 1 by the bearing strength of the soil; this gives the square feet of area needed.
Side Thrust on Curves – An outward pressure exists on all deflections from a straight line.
Good soil, properly tamped, can be sufficient to hold side thrust – unless soil conditions are unstable. In that case, to anchor against this side thrust, the blocking should be placed against the pipe on each side of the coupling. Do not thrust block the coupling itself.
Side Thrust

2” 7.9
2 ½” 11.6
3” 17.1
3 ½” 22.4

Based on side thrust per 100 lb./in² pressure per degree of deflection.
Note: Multiply side thrust pounds by degrees of deflection times pounds of pressure divided by 100 to obtain total side thrust in pounds.
5. 2,000-psi test minimum on thrust block meeting all ASTM specifications
C-33 and C-150 or C-175 standards. Note: Thrust blocks can differ depending on the type of fittings and soils. Contractor must review all conditions for adequate thrust. Furthermore, a joint restraint may be required to obtain and secure a fitting from movement.
