The Department of National Defence's oil containment dykes couldn't hold
water, let alone the fuel oil they were designed to contain in the event
a leak from the 3,000-gallon (13,650-litre) tanks they surrounded.
The concrete dykes are supposed to be pumped out after a heavy rain fall,
but DND staff found it wasn't necessary; the dykes emptied themselves quite
efficiently despite the fact that they were built to be waterproof. Two
dykes, about 640 square feet (57.6 square metres) located at the Osborne
Head Gunnery Range near Halifax, NS, were only eight years old and had
been patched wherever cracks could be seen, according to Contract Insp.
Don MacLennan, but they continued to leak.
If oil from a ruptured tank had leaked out as quickly as rainwater, DND
would have been looking at a hefty bill for site excavation and polluted
soil treatment, MacLennan said. Instead he called PERMACRETE® to treat one
of the two dykes on site.

PERMACRETE®'s solution was to apply a protective lining of PERMACRETE®
RUBBER COAT™ to the base and eight inches (20.5centimetres) up the sides
of the concrete dyke.
"I was down there after a heavy rain we'd had," MacLennan says. "The dyke
that had been treated had three inches of water in it and the sumps were
all full. The other one had not a drop of water in it. We're so pleased
with the job PERMACRETE® did on the dykes that we've asked them to do the
others."
