Since I have already introduced myself in the introductions section, I will skip that and get right into what my current problem is.
Problem: Part 1) Interior: I have water seepage in my basement (fieldstone foundation) on the front wall of the house, no where else. I only get standing water when hurricane-like conditions are present and when the winter snow is melting.
The use of the basement is for storage on metal shelving units and a hobby table/work bench. I have 2 de-humidifiers running almost constantly to keep the humidity around 45 to 50 %.
Part 2) Exterior: The "skirt" of the foundation is all broken up and the mortar is chipping and falling out. Basically IMO, it looks ugly and is providing passages for water to get into the wall. Thus seeping into the inside of the basement.
Tasks to completed: 1) The land all needs to be graded away from the house, this I will do myself.
2)Gutters will be replaced.
3)Exterior of foundation to be re-mortared/waterproofed.
Other pertent information: -I live in central Mass
-House built in 1939
-I have received 2 quotes for someone else to do all of the work:
1) Dig trench 3ft wide and 3ft down, re-mortar the stones and install a membrane. $15,000
2)Dig trench 3ft wide and 5ft down, re-mortar the stones and install a membrane. $19,000
Things I need help/advice on: 1) How far do I need to dig down around the foundation? I have been told 3ft and 5ft and the reasoning is to get below the frost line.
2)Once the trench is dug, the plan is to remove old and loose mortar and replace with new stuff. What should I use? I have been told hydralic cement and several different types of mortar.
3)Should I use a "membrane" on the exterior of the foundation? Or will re-mortaring the foundation be enough?
Thanks in advance!!
