In general people will tell you that a thicker flooring product will be more robust to areas where the floor isn't flat, but the best solution is to always start with a properly prepped subfloor. 

Benefits of post framing include but are not limited to: more efficient use of lumber, thicker wall cavities, large roof spans and quick to dry-in.

@Lewis Thompson I got the Graco X7 because it can spray thicker liquids such as DryLok.

Just make sure your subfloors don’t have any major changes in elevation because, over time, the thin tongue and groove lock strips will snap from flexing.I used an click lock engineered hardwood flooring in a dining and kitchen area for a BRRRR recently since it was much thicker and didn’t flex in the small uneven spots.

The thicker the better. 

I used the thicker ones from Home Depot.

It’s basically a thicker, but narrow strip of tile that can cap off the end of what you have.

Opt for thicker material with a built in pad on the back - it will sound much better walking on it, cheap stuff is sometimes hard to install.We do not follow the fashionable white and grey trend with flooring and stick with medium browns, they have more staying power long term.

Usually, only heating oil USTs associated with commercial properties are regulated. thus, most home heating oil tanks may and often are taken out of service without any oversight from state regulators.Second- the rules that are in effect for heating oil tanks are usually less stringent than for diesel or gasoline tanks since heating oil tends to thicker and may not migrate as far. as a result, many states just require tanks to be cleaned out. they may also require the tanks to be filled with sand or concrete to prevent collapse. but sampling may not be required.Third- the key to determining if a tank has leaked is to collect soil samples from around and beneath the tank (groundwater also if groundwater is shallow). another quick way to see if a tank is leaking is to "dip" it with a stick that has a paste that turns color in the presence of water. generally, if water has gotten into a tank, it can mean oil has leaked out of the tank (although a certain amount of condensation may be present even where there is no leak so this is not a infallible test).Fourth- if there is currently a tank in the basement, ask the owner if there used to be a buried tank (a/k/a underground storage tank).Fifth, If the tank has impacted the soil, the cleanup generally varies from $25K to $50K though the costs will depend ont he depth of the contamination. i once had a home with a heated pool that had pressurized piping and used diesel. the contamination went down 40 feet and the consultant went crazy excavating the soil to the tune of $400K!!!

Their sense of entitlement has distanced us and caused me to grow a thicker skin.
