Circular Formwork


Customizable radius formwork for water and sewage treatment system construction.

MEVA Formwork Systems is dedicated to providing simple and innovative solutions to the challenges that structural concrete presents in the construction of water and sewage treatment facilities.

The MEVA Adjustable Radius (MAR) system is the answer to these ­common problems. With only a few simple parts to assemble, MAR can be erected on site with minimal time and effort. The system can also be pre-assembled, with the radius preset for initial use. The radius can then be easily adjusted on the job site to suit your for future pours, saving ­time, costs and labor.
