Brick Sewer
19th October 2019Brick Sewer
Ancient times mostly bricks were used as a sewer material, However, they have now almost been replaced by concrete cement sewers.
However, the brick sewer may still be used at places where the sewers are required to be constructed at the site, and if the ingredients needed for cement concrete sewers may not be easily available. They may also be preferred for constructing large-sized combined sewers, or particularly for stormwater drains.
Brick sewers are generally plastered on their outer surfaces so as to prevent the entry of tree roots and groundwater through the brick joints; are lined inside with stoneware or ceramic block so as to render them smooth and hydraulically efficient.
The stoneware or ceramic coating also helps in resisting sulphide corrosion which is not possible with the ordinary cement plaster as the same is easily attacked by sewer gases like hydrogen sulphide.
