And these voids can be filled with water,

00:00:03.599 --> 00:00:05.499

reducing its strength and stiffness,

00:00:05.499 --> 00:00:07.233

and potentially lead it to collapse in,

00:00:07.003 --> 00:00:09.133

as we've seen with Highway 36.

00:00:11.003 --> 00:00:13.002

[narrator] Further examination indicated

00:00:13.002 --> 00:00:16.599

that the problems may have run deeper than the drainage.

00:00:16.599 --> 00:00:19.353

In a layer of clay that the retaining wall was built on.

00:00:19.353 --> 00:00:19.433

In a layer of clay that the retaining wall was built on.

00:00:20.009 --> 00:00:24.001

Paradoxically, it might have slowed the collapse

00:00:24.001 --> 00:00:27.002

but also made it inevitable.

00:00:27.002 --> 00:00:32.699

{\an8}Clay and clay-like soils are made up of small closely-packed grains.
