Plumbers Construct Underground Drainage.

The old Redeemer sanctuary and lower level fellowship hall were known to have regular water problems.  A combination of 1940’s building methods and depreciation caused by the simple passage of time frequently caused Redeemer recurring water damage.  Now, eighty years later, the new sanctuary will benefit from the knowledge and systems appropriate for our local water conditions.

First, the concrete reinforced foundation walls are waterproofed.  This includes:

• grouting all the openings made by steel ‘spacers’ in the concrete walls,
• painting a primer on the outside of the foundation walls,
• installing a water-proof ‘peel-and-stick’ style board on top of the primer, and finally
• installing a corrugated drain board on top of the water-proof board to drain water down the wall.

Second, a combination of hard PVC pipe and flexible plastic hose is installed around the footings, at the base of the walls, to collect the water that runs to the bottom of the foundation walls.  This is covered with pea-size gravel and then fill dirt that is meticulously compacted in 12″ layers.  Later, a complementary system will be installed on the interior of the foundation walls, below the lower level floor, to collect and channel water to the exterior of the foundation.

Third, the entire drainage systems, inside and outside the foundation, will connect to a new main feed that eventually connects to the city sewer line under Maple Road.

PVC pipe and flexible tubing is staged for use in the new drainage system.
