Sewer Manholes

Specialised Fibre Cement (F/C) manhole design which is suited to areas of
high water table. The design offers a sealed manhole.

Dolomite Sewer Channels

Glass re-enforced concrete is a strong durable mix of fibre-glass, cement,
and dolomite aggregate. Dolomite aggregate is used for the superior
resistance to corrosion as experienced in sewer systems.

Mining Channels

Underground water is often channeled away by means of half-round, or semi-circular channels. The problem facing the installer of these channel systems is ease of use and economics of any system offered. M4A manufactures a light weight, easy to use, and robust system.

Pre-cast Concrete Plinths

M4A concrete capabilities include a
range of standard plinths for the electrical
contractor, as well as special items
manufactured to order.
