Abstract
A dual channel drainage seal for enclosing a joint between a slab and a foundation sidewall of a subterranean area. The drainage seal includes and lower channel and an upper channel stacked over the lower channel. The lower channel is affixed on top of the slab and against the sidewall to form and enclosed channel for retaining and routing radon and/or water seepage at the joint to a sump pit. The upper channel is open on top and configured to capture and route water seepage from the sidewall above to the sump for discharge, thereby protecting the interior portions of the slab from radon and water damage.

A dual channel drainage seal for enclosing a joint between a slab and a foundation sidewall of a subterranean area, the dual channel drainage seal comprising:
- a first vertical wall section having an outer surface configured for placement against the foundation sidewall and an opposing inner surface;
- a second vertical wall section spaced-apart from the first vertical wall section and having an inner surface;
- a first horizontal wall section having a first end affixed to a lower portion of the inner surface of the first vertical wall section and a second end affixed to a mid-portion of the inner surface of the second vertical wall section;
- a second horizontal wall section affixed to a lower edge of the second vertical wall section, the second horizontal wall section being configured for placement against the slab, wherein the first and second horizontal wall sections and the first and second vertical wall sections are fabricated from a non-perforated, fluid impermeable material;
- and
- wherein the second horizontal wall section, a lower portion of the second vertical wall section and a bottom surface of the first horizontal wall section collectively define a lower channel, and wherein an upper surface of the first horizontal wall section, a portion of the first vertical wall section which extends above the first horizontal wall section, and an inner surface of the second vertical wall section which extend above the first horizontal wall section collectively define an upper channel of the dual channel drainage seal, wherein the upper channel is arranged over and is isolated from the lower channel such that the upper channel and lower channel are impermeable to fluid flow therebetween.
An elongated dual channel drainage seal for enclosing a joint between a slab and a foundation sidewall of a subterranean area, the elongated dual channel drainage seal comprising:
- an impermeable upper drainage channel stacked over a lower drainage channel, the lower drainage channel having at least one sidewall configured to abut against the slab and form an enclosure between the slab and the foundation sidewall;
- and
- the impermeable upper drainage channel having at least one sidewall configured to abut against the foundation sidewall, wherein the at least one sidewall forms a U-shaped channel having a top opening configured to collect seepage through the foundation sidewall at height above the U-shaped channel, and wherein the impermeable upper drainage channel is arranged over and is isolated from the lower drainage channel such that the upper drainage channel and lower drainage channel are impermeable to fluid flow therebetween.
