Some homeowners may feel that they have the time and the ability to install the corrugated metal pipes that they have bought for the drainage system of their property. However, such homeowners may make several mistakes that may affect the function and durability of those metal pipes. This article discusses some of those mistakes that you should avoid making during corrugated pipe installation.
Using the Wrong Backfill Material
Some homeowners may see no problem in using the excavated soil as a backfill material once the corrugated metal pipes have been placed in the trenches. However, that soil may not be the right backfill material to use if you would like the pipes to be undisturbed during their service life. A geotechnical engineer may be required to assess that soil in order to confirm that it will be appropriate to use as a backfill material once the pipes are laid. You should therefore avoid using the excavated soil as a backfill material until an expert has given you his or her approval.
Using the Wrong Placement Technique
The backfill material should be placed around the corrugated metal pipes carefully so that the pipes are not displaced or distorted. Any mistakes made at this stage can cause the pipes to alter their slope angle. The weld joints where the pipes were joined can also give way once excessive pressure is placed upon them when the pipes move out of alignment. You should therefore ensure that you place small quantities of backfill material on each side of the pipes until all the fill material has been transferred into the trench. This balanced approach will ensure that the pipes are not displaced or distorted.
Using the Wrong Compaction Tools
Compaction of the backfill material is important for several reasons. First, it helps to prevent the pipes from shifting after installation. Second, the compacted backfill material protects the pipes from the weight of any traffic moving above the pipes, such as moving trucks that are driven over the buried pipes. A manual tamping tool may therefore be unable to compact the soil to the proper degree. Use a motorised compactor to compact the backfill material adequately so that the buried pipes will be shielded from the weight of moving vehicles.
Avoid making the mistakes above when you lay corrugated metal pipes on your property. You will then have no reason to fear that the pipes will not perform as expected.
