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.
Steel and Other Fabrications
Our internal fabrication capabilities allow us to extend our concrete offering to custom
steel fabrications to supplement our other product ranges.
