Sept. 15 Lots involved with the foundation - things that we take for granted in a house are built into the foundation - if it is not done correct now, there will be problems later on. The biggest thing is drainage - drainage around the outside of the foundation is a multilayer process:
- the concrete is painted with a bitumen product (we used to call it tar)
- the foundation is wrapped in a waffle sheet of PVC that is stapled to the concrete
- a perforated pipe is buried at the base of the foundation to take water away (like weeping tile used to function)
- a gravel product, called 'crush' is filled in next to the foundation so no organic material is in contact with the foundation, and promote drainage of moisture away from the foundation.
Also next to the foundation is the drainage system from the house - very cool.
