Cement along with crushed rock or sand and water are the key ingredients of concrete. The cement for the Basement footings, walls and floor was manufactured by the Monarch Cement Company in Humbolt, Kansas.  

Millions of  tons of a product called flyash are produced each year as a by-product of coal-fired energy production. Flyash was also used as an ingredient  in the concrete mix for this house. It was added to the concrete mixture as a substitute for some of the cement. It bonds chemically with the cement, making it stronger, more water repellant and more durable.

Waterproofing system. View from the Southwest corner of the Basement.

Epro System III Plus waterproofing was applied to the Basement walls. This system consists of a sprayed applied waterproofing, a 10 mil protection course and 24 mil drainage mat. The spray applied base membrane is a water-based, anionic bituminous asphalt emulsion modified with a blend of synthetic polymerized rubbers. The 10 mil protection course is a high-strength geo-membrane made from a blend of polyethylene copolymers that is impermeable to water and resists backfill damage. The drainage matt consists of a lightweight extruded “dimple” design core, with a heat-bonded polypropylene filter fabric that eliminates hydrostatic water pressure on the Basement wall. This system will enhance the indoor air quality and the comfort of the Basement as additional living space.

Before the Basement floor can be setup to pour, the drain and vent piping system is installed. The large white pipe entering the Basement on the right is the sewer line. This pipe will extend to the main sewer line in the utility easement on the East side of the lot. The smaller white vertical pipe will be a vent that will eventually extend through the roof.
