Maintenance Holes

Overview

Precon’s precast Maintenance Hole stations are made up of a combination of bases, barrels and tops that are easy and fast to install. We deliver high quality, precise, leak-proof maintenance hole systems that are the backbone of municipal water infrastructure. Precon offers Maintenance Hole diameters ranging from 1219mm to 3000mm (see size chart for heights) and they can be stacked to accommodate any desired height (including stepping down diameters to reduce cost to get to grade). Upgrading the maintenance hole station is possible by adding unique tops with hatches or lining the entire station with HDPE for corrosive environments.

Precon utilizes Schlusselbauer’s Perfect Base system for all pre-benched bases sized 1219ø, 1525ø and 1839ø.
