Basement waterproofing in Amsterdam, NY
Practical drainage solutions for older masonry basements and newer poured foundations.
Older basement walls can pass moisture through several mortar joints at once, while newer foundations are more likely to show a concentrated crack or seepage at the wall-to-floor joint. Both require the same first step: identify the path before deciding how much work is necessary.
Where moisture is spread across a wall, wall drainage and an interior perimeter system can work together. Where the problem is isolated, the answer may be smaller. We explain the difference during the inspection.

Basement questions from Amsterdam homeowners
Why is water coming into my basement?
In almost every case, because water in the surrounding soil has nowhere better to go. Rain and snowmelt saturate the ground around the foundation, pressure builds, and water moves through the weakest available path — a crack, a mortar joint, the joint where the wall meets the floor, or up through the slab.
Why does my basement leak after heavy rain?
Heavy rain saturates the soil faster than it can drain away. The soil against the foundation holds that water, hydrostatic pressure rises, and the wall and slab are pushed on from outside. Once the soil drains down, the leaking stops — which is why the basement seems fine again a few days later.
Why is water coming in where the wall meets the floor?
That joint — the cove joint — is a seam between two separately poured elements, not a sealed connection. It's one of the lowest points in the basement and one of the easiest paths for water under pressure. Seepage there is extremely common and is a drainage problem rather than a structural one.
What is hydrostatic pressure?
The pressure that standing water in saturated soil exerts on whatever is holding it back. Water is heavy, and when the soil around your foundation is full of it, that weight pushes against the walls and up under the slab. Relieving it — by giving the water an easier route — is the whole idea behind interior drainage.
