“Will do.”
Vlade clumped downstairs to the sub-basement and the lights came on ahead of him as he moved. The sub-basement was not only below the waterline, it was below the rockline as well, as it had been cut into bedrock at the time of the building’s construction, in the first years of the twentieth century. Every part of the building but the tower had been replaced in 1999, when the foundation had been dug deeper still. No one then worried about waterproofing, and the bedrock had cracks in it, as all rock did. When the island had been dry land that hadn’t mattered, but now it did, as water from the canals seeped slowly but inexorably down cracks in the rock. The concrete cladding the walls of the sub-basement was therefore harder to seal than on the floors above, because you could get to the outsides of those higher parts of the wall, either by diving to them or by caissoning the canals. Access was all, and given the lack of access he could only seal the sub-basement on the inside surfaces of its walls. This was profoundly unsatisfactory, as it left the concrete of the walls and floor exposed to seep, and thus getting degraded in the usual ways: corrosion, melting, slumping, disintegration. But there was nothing to be done about it.
Because of this unsolvable problem he kept the sub-basement empty, its floor and walls entirely clear. Some people on the board complained that this was a waste of space, but he was adamant. He had to be able to see what was happening. It was one of the worst vulnerabilities in the whole building.
So when he hurried into room B201, he could see all of it immediately. A big bright space, looking wet everywhere because the lights reflected off the so-called diamond sheeting that covered every surface. It was actually a graphenated composite, but as it was transparent and shiny, Vlade like everyone else called it diamond. It was not quite as hard as diamond, but it was more flexible and could be applied as a spray. Really the new composites were simply wonderful when it came to strength, flexibility, weight, everything you wanted out of building materials. They made submarine living possible.
The floor was slightly knobbled to create better footing; the walls were smoother but brushed like brushed aluminum, precisely to reduce the glare of reflected light. What it meant was a glitter instead of a glare, a glitter as if everything were damp and sparkling with dew. It was enough to give him a little startle of dismay, even though it always looked this way.
That being the case, he had to search around to find the leak. The building had indeed reported the first sign of moisture; he only found it by deploying his humidity sensor wand. The damp spot was in the far corner, where the north wall, east wall, and floor met. Which was odd, as a point like that was precisely where the sheeting got sprayed thicker than usual. Still, this was where the wand was pinging. He sat down on the cool knobbled floor, brushed his hand over it. Yep, wet. He smelled the damp, got nothing. Took his flashlight from his tool belt and aimed the strongest beam at the corner. It took some moving of his head back and forth to find the right focus for his old eyes, but finally he spotted it: fracture. Microfracture.
But this made no sense. He whipped out his pocket lens, leaned over on his knees and held the flashlight at an angle, moved the lens in and out. Blurry big view of the blob of diamond spray that had congealed or dried or what-have-you in the corner. Fracture, yes. Welling water in the crack grew till the surface tension on it broke and it slid onto the floor, just as it would have at larger scales. But fuck if the hole didn’t look drilled.
He swabbed the corner clear, took a macro photo with his wristpad. The crack indeed looked round, like two little holes actually, the water welling up hemispherically like blood from two pinpricks. Clear blood. “Damn.”
He swabbed it again, then pasted over the corner with a dab of leakstopper. He wanted something more substantial for later, like a thick spray of sheeting, but for now this would have to do.
“Vlade,” the Met said in his earbud, “mayday. Water in the midbasement, southwest corner, room B104.”
“How much?”
“First detection of moisture. Speed of inflow undetermined.”
He hustled up the broad stairs and across the room surrounding the stairwell to room B104, favoring his bad left knee. The rooms on this floor were smaller than the ones on the floor below. He kept them equally empty against the walls, though their middles were filled with boxes in stacks he had organized himself. The floor was ordinary concrete, the walls diamond sheeted, as below. Here the outside of the building was in water even at low tide, as was true of the floor above it, the old ground floor. The one above that was intertidal. Right now it was high tide, so there would be a little more pressure on any submarine leaks, but for two leaks to spring at almost the same time struck Vlade as extremely suspicious, especially given the corner position and drilled look of the one below.
Again his humidity wand led him quickly to the leak, which was low on a wall. Here the wall was sheeted both inside and outside, so a leak made even less sense than the one below. This one looked like a crack rather than a pinprick. Like a stress fracture perhaps. Water oozed from the bottom of the crack, which was almost vertical. Beads of water, welling up and dripping down the wall.
“God damn it.”
He gooed the crack with another liberal dab of leakstopper, thought it over, then stomped around the elevator shaft to his room. He got out of his Carhartts and into his swim trunks, cursing all the while. The lower leak would necessarily have been drilled from the inside. He didn’t want to give any oral commands to the building about the security cameras, because the camera issue had not been resolved to his satisfaction yet, and the whole system could be compromised. So he would have to wait to check that until others were there to help and witness. First order of business was to inspect the outside of the building to see if the higher crack extended all the way through to the outside. If it did, that would be simpler than if it was a complex leak in which the interior crack was not matched by an exterior one. But either way was bad.
The wetsuits and dive tanks and gear were in the boathouse, in a storage room next to his office. People were getting out in their watercraft without undue stress, it seemed, and Su nodded nervously to him that all was well. “I’m going to take a quick dive,” Vlade told him, which caused Su to frown. Dives were never supposed to be solo, but Vlade did it all the time around the building, accompanied only by a little sub sled.
“I’ll keep the phone on,” Su said, to remind him, and Vlade nodded and began the somewhat arduous process of getting his wetsuit on. For building inspections he could use the smallest tank, and the headset was just a mask settling onto the hood like a snorkel mask. The seal was not completely hermetic but good enough for brief work near the surface, and he could scrub down afterward.
There were steps down into the water inside the boathouse. Only three were now exposed, which meant it was almost high tide. Down he went, feeling like the swamp thing from the eponymous movie, the scariest movie of all time in his opinion. Happily he was not dragging some poor rapidly aging maiden down with him. Nor even the sled, which was not needed for a dive like this.
The water was cold as always, even in the wetsuit, but he had been warming up so fast that it felt good to be cooled. Submerge, quick test of the gear, then out the boathouse door into the bacino, swimming horizontally. The wetsuit’s feet were just slightly webbed and finned, and that too felt good. Headlamp on, powerful beam, nevertheless mostly catching the particulates in the god-awful water of the city, as always. Actually the hundreds of millions of clams in the aquaculture cages all over the intertidal were doing yeoman work in filtering clean the water. Now he could usually see at least two or three meters, and sometimes more. Stay deep enough to not get knocked on the head by some boat’s keel or prop, but high enough not to run into the bacino’s aquaculture pens. The familiar weightlessness of neutral buoyancy, of horizontal underwater life. Lots of fish in the highest cages: salmon, sea trout, catfish, the sinuous schools of fishy bodies all turning together against the cage sides.
