A 6' level, or a long straightedge and shorter level. Check the interior plane of the wall vertically in a few spots and see if there's any deflection. In my experiences of repairing block walls professionally, excavating/removing the soil from the exterior only removes the lateral pressure and the wall slowly returns to wards it's original position on it's own. Can't say I've ever seen one worse after excavation, but i suppose with an erratic operator on a piece of heavy equipment, it's possible.

Basement waterproofing


The neat part with this house is that it's sitting on bedrock, which helps with the settling. If the excavating (assuming it's done properly, i'll do my due diligence in hiring someone qualified) is done properly, then as Jomana mentioned, it shouldn't make it worse... hopefully

I'll talk to a civil engineer and see what he has to say as well, next time he's in town

Basement waterproofing


The fact that you are just above rock increases the problems since the water will most likely have no place to go and probably increased the soil pressure on the wall and also could cause more leakage and some bowing.

You probably did not "fix" the real leak, but eliminated where the water showed up inside. You could end up chasing leaks all around the basement and then end up with the final "leaks" showing up at the joint between the wall and interior slab or the pressure causing slab cracks that can leak. It is a normal progression in many homes.

Drain tile and proper bedding and backfill will eliminate the excess water and reduce the soil pressure on the wall and slab. - Either interior or exterior, but no stick on water collectors around the basement that just collect the water after it has leaked into the living space. A proper interior drain tile system will lower water level long-term as well as an exterior system and may be cheaper if you have landscaping, sidewalks, patios or attached garages since water moves horizontally and in some cases upward by capillary action.

Basement waterproofing


That is quite an involved process for a basement leak! Typically, water enters into the basement through one of two ways (sometimes both): 1) crack in the basement wall or floor, or 2) concrete pores. Most hairline cracks and cracks measuring up to 1/2" can be repaired using a high pressure hydrophobic polyurethane crack repair kit - they make them for DIY users. If the crack is in need of structural repair and is not leaking, an epoxy could be used. Next, you want to use a penetrating, permanent waterproofing sealer kit which can be applied on the interior of the basement. Seal your walls and floors with it. For added protection, you can use a surface waterproofer once the pentrant has had time to cure. Sump pumps can be added to your basement but those only come in handy once water has already entered. You can add a waterproofing membrane to the exterior but that isn't always needed and can eventually breakdown. Before investing any more money, I would find the source of the leak and determine if all the work you are doing is even necessary.

You just have to look at what is causing the leaks. - It is not as simple as putting or slopping on some stuff for a lifetime guarantee.

In over 40 years of being involved in design, construction and consulting, I have never seen a single products that does an adequate waterproofing job, because the causes are so different - climate, soil types/layering, hydrostatic pressure, soil pressure, cracking, settlement and vagueness of the original construction.

Sump pumps can be great because they a positive method to remove water BEFORE it gets into the living area. Since water does not follow a "neat" gravity-only law, the water and pressure commonly is from below the building "footprint".

LThanks guys, the original leak was fixed but I figured the membrane will help any future potential leak
