Exterior Waterproofing for North Lake homes

A lot of houses around North Lake started out as summer cottages. Over the years they were winterized, expanded and turned into full-time homes, and the basements came along for the ride. Many are shallow and older, built when nobody planned to store anything down there. Now they hold furnaces, water heaters and storage, and the water that seeps in every spring causes real trouble.

Living this close to the lake means groundwater sits near lake level, and it rises when the lake does. That puts steady pressure against the wall from below and from the side. Additions make it trickier. Many North Lake homes have a newer room or garage built on a different foundation than the original cottage, and the seam where the two meet is a common spot for leaks.

Exterior waterproofing works well on these homes because we can see both foundations once they're dug out. We excavate to the footing, repair the old wall and the joint to the addition, then seal everything with a liquid membrane and dimple board. New weeping tile goes in with washed gravel, and the backfill is graded away from the house. Where the lake lot is too tight to dig, we'll talk through interior drain tile. When the Town of Merton requires a permit, we pull it.

What's Included

What exterior waterproofing in North Lake includes

For a North Lake home where the old cottage and the addition sit on different foundations, exterior waterproofing covers these four steps:

Excavation to the footing

We dig along the leaking wall down to the footing so the whole face of the foundation can be cleaned, repaired and sealed.

Liquid waterproof membrane

Cracks get hydraulic cement, then the wall gets a thick elastomeric membrane that keeps water off the concrete.

Dimple board and weeping tile

Dimple board gives water a gap to drain down, and new perforated weeping tile at the footing carries it away.

Washed gravel and regrading

Washed gravel around the tile keeps it draining, then we backfill and grade the soil to slope away from the house.

What homeowners say about our crew

★★★★★

They replaced our drain tile, put in a sump pump, set steel beams, and sealed the basement walls - then redid the window wells and buried a downspout outside. The price was competitive and Nick, Luis and the crew explained everything as they went.

Structural work comes first on a moving wall. Each crack is cleaned out and packed with hydraulic cement and structural sealant, which shuts off both water and movement at that spot.

Questions, Answered

North Lake exterior waterproofing FAQs

Usually, yes. Shallow walls are quicker to dig, and we seal them the same way: membrane, dimple board and new weeping tile at the footing. We'll look at the wall once it's exposed and tell you what we find.

Two foundations built at different times settle and move a little differently. The seam between them opens and lets water in. We dig out that corner, repair the joint and seal across both walls.

It helps a lot with pressure against the wall. The new weeping tile needs somewhere to drain, and we'll work out where on your lot before we quote. If the setup calls for a sump too, we'll explain why.

Some excavation and drainage work needs one. When the Town of Merton requires a permit, we pull it. You won't have to call around.

Before you finish or store things down there is the easiest time. An inspection tells you where water gets in and what it'll take. You'll get a written quote to plan around.

Most lots give us enough room along the walls that matter. If a side is too tight for excavation, interior drain tile is the other route. We'll show you both options if it comes to that.

Exterior waterproofing keeps the water off the wall before it reaches the floor. How quickly we can start depends on the season and the ground. Same-week inspections are common, so you'll know the plan fast.

We only dig along the foundation wall we're waterproofing. Plantings and edging in that strip get set aside first. The backfill is graded away from the house when we finish.

A cottage-sized home usually takes a few days. Joining old and new foundations can add a little time for repairs. We'll give you a timeline up front.

Yes, our lifetime warranty transfers to the next owner. On a lake property, that's a strong point to show a buyer.
