BRHC is able to offer concrete manhole chambers which are now become an essential requirement for all government construction projects and private infrastructure sites as well. We strive to innovate concrete drainage system to achieve faster build time at project site with minimized environmental impact. BRHC’s watertight chamber rings are a perfect offsite concrete solution designed to provide superior quality and safety at the site. It also reduces the costs of application and installation as the assembly of the complete top to bottom manhole system is systematic and rapid.

The BRHC concrete manhole system design includes a prefabricated RCC conical top unit, an RCC monolithic base unit finished with predetermined combinations of inlets and outlets and desired number of chamber rings which are known as concrete riser rings to get the adjusted height of the manhole.

All the manhole assembly including conical top unit, monolithic base units, and concrete riser rings are made up of thicker, denser and stronger concrete walls. This robust design justifies that the need for a concrete surround around the drainage pit is eliminated unless specially required at the construction site.

The precast manholes manufactured by BRHC are at the stockyard in round shapes and square shapes with various sizes and dimensions. BRHC manhole system is also applicable to underground utility rooms for gas, telephone or electricity infrastructures. These manholes can be applied as stormwater manholes, drop manholes, sewer pipeline junctions, catchment inlet structures, caisson chambers, off-take risers and soak holes utilities. BRHC Concrete Industries deliver the complete range of precast drainage products all over India.

The city planners started requiring BRHC manholes in most of the stormwater management plans to properly handle the stormwater runoff. The reason behind it is that the Precast concrete manholes function as an integral part of any stormwater system and can be counted on to perform exceptionally for many decades.

Benefits of installing BRHC’s precast concrete manholes:

1. Precast concrete is considered as robust, sturdy and indestructible. Hence it provides the virtue possessors a full life cost which is very reasonable and the produced manhole definitely get manifested service existence of more than 125 years span. BRHC’s quality control team always ensure use of quality raw material to design dense concrete.
2. Concrete drainage manholes system are drawn to combat whole of the roadway automobile loadings and these manholes are manufactured with the manhole cover slab enduring straight and right onto the barrel panels of the chamber. The concrete slab not at all need exorbitant composition to segregate it from the concrete manhole chamber panels and thus it eliminates the provision of another support to bear heavy traffic weights. BRHC manufactures super solid concrete cover slabs.
3. The product load of the concrete itself provides natural defiance to float away during any case of calamity such as flooding or in high groundwater levels. BRHC manholes are capable of holding strong at infiltration and acid reactions due to mordant conditions.
4.   BRHC manufactures the concrete manholes which stand extremely tough against devastation from high-pressure water jetting situations.
