【HaiChuan Engineering Discussion】Plastic sewage inspection wells – which are better than those made of masonry?
Thread Content
Which is better, plastic sewage inspection wells or those that are built with bricks? Cost? Quality?
Plastic openings are easy to pre-make, but masonry is prone to leakage
It seems that the time cost associated with masonry is high, the efficiency is low, and there are many steps involved
Plastics are highly resistant to corrosion, easy to install, and do not leak easily, but they have low compressive strength and require careful foundation treatment. If the foundation sinks, it is easy for the pipelines to deform and crack. The opposite of masonry.
