Culvert Repair in Pelham, NH ‼️
Due to poor compaction and an improper repair prior, this homeowner found their driveway sinking.
We managed to excavate and remove the damaged section of culvert;
Sleeve some 8” SDR40 through the remaining functional 10” HDPE culvert, and sealed it tight with a Mar Mac dissimilar pipe coupler;
The switch to 8” SDR40 allows for a sturdier section of pipe and additional cover below the asphalt surface.
We finished off the job by properly backfilling and compacting the trench getting it ready for asphalt.
