The “Big Pour” Milestone Passed

The Mayor’s Report with Pelham Mayor Dave Augustyn

By Mayor Dave Augustyn – Last Thursday, the construction of the new Pelham Community Centre (PCC) passed another milestone – the “Big Pour.”

You see, the Big Pour was when Ball Construction oversaw workers using a concrete pump truck and special laser leveling and polishing machines to continuously pour, level and smooth the floor of the Accipiter Arena in the PCC.

The set-up began weeks ago when workers smoothed sand across the leveled and prepared ground. Then, they weaved black heating pipe on top of the sand, and covered that with more sand. That heating pipe will circulate excess heat from the Ecco-Chiller ice machine along the ground to stop the build-up of permafrost.

I understand that permafrost isn’t too much of a problem in rinks that don’t have ice for one-third of the year – like the current Pelham arena. However, arenas that maintain ice into the spring and late summer or year-round, permafrost can build up and heave the concrete floor! A build-up of permafrost heaved the concrete ice-pads in the St. Catharines four-pad arena, for example, following a malfunction of the heating pipe / coil.

Then crews secured two layers of dense, “Ultra extruded” Styrofoam insulation across the sand. On top of the Styrofoam they weaved a lattice of pipes, rebar, and a metal frame that formed the core for the pad’s concrete floor.

Impressively, they checked and double-checked every square inch of the lattice and held the piping under high-pressure for three weeks so they could check the pipes, seals, and other materials. Since this passed the tests with flying colours, Ball Construction organized the Big Pour.

To ensure a constant supply of concrete for this continuous and seamless pour, Ball Construction not only secured an exclusive concrete supply from one plant, they also had another concrete factory on “stand-by” in case anything went wrong.

After the polishing and during the curing of the concrete, Ball Construction will cover the floor with water. When they slowly drain that water, they will note any high or irregular spots in need of further polishing – so that the floor will be as level as possible.

It was my honour to witness the Big Pour along with the Oversight Committee and some of the major fundraising donors to the Community Centre. And, I was delighted that two local, retired NHL players – Doug Freeland and John Stringer – also watched part of that Big Pour last week.

After this milestone and with 98% of the Centre tendered and because of the hard work of Ball Construction, all the trades and Town Staff and the Oversight Committee, the new Community Centre is on-budget and on-time to open next summer.
