Your sump pump pushes water out… but where does it go from there? 💧

in Marlboro, we installed approximately 130 feet of solid PVC drainage pipe, connecting three gutter downspouts and the sump pump discharge, running under the sidewalk and out to the curb.

We also added two cleanouts, flushed the gutters, replaced the window wells with heavy-duty wells, and added drainage stone. Concrete repairs, grading, seed, hay, and cleanup finished the job!

From collecting the water to giving it somewhere to go, every part of the system matters. 💪

Today we kicked off a new basement renovation, and we’re excited to bring you along from day one. There’s plenty of work ahead, but watching a space come together is one of our favorite parts of the job.

These are the “before” days—the dust, the mess, and the beginnings of a big transformation. Follow along as our crew gets to work and this basement takes shape! 💪

🔵 What’s that blue layer we put on foundation walls?

That’s Henry Blueskin waterproofing—an exterior barrier that helps keep water in the ground from making its way into your basement.

Here’s how it works 👇

✅ Bonds directly to the foundation: After the wall is properly prepared, the membrane adheres to it, helping prevent water from traveling behind the waterproofing.

✅ Creates a waterproof barrier: Its rubberized asphalt layer and blue outer film work together to block water. Overlapping seams and properly sealed details keep that protection continuous.

✅ Works as part of a complete system: Protective layers and drainage help protect the membrane and manage water around the foundation.

The blue layer matters—but the prep work and installation matter just as much! 💪

Rainwater needs an exit plan—and hanging out around your foundation isn’t it! 🌧️🏡

For this drainage project, we’re installing a French drain along the front/side of the home, tying in the gutter downspout, and running solid drainage pipe to a pop-up emitter near the curb to carry water away. 💪

We’re also adding a cleanout for future maintenance and finishing with grading, grass seed, and hay. A lot happens underground, but the details make the difference!

💧 Your basement shouldn’t come with a rain forecast.

For this Piscataway project, we’re tackling water issues from the outside—right down to the foundation footing. 💪

The plan includes:
✅ Henry Blueskin exterior waterproofing
✅ New footing drain connected to the sump system
✅ A larger sump basin
✅ Clean stone for drainage and grading to direct water away from the house
✅ Seed, hay and cleanup to finish the yard

A lot of this work ends up underground, but every step matters when the rain comes.

💦 Another drainage problem tackled by GSL! 💦

This homeowner was dealing with a flooded sun porch thanks to an undersized drainage setup and a French drain system that just wasn’t keeping up.

After checking everything out, we came up with a better solution built to actually handle the water — not just put a Band-Aid on the problem. 🙌

Our price wasn’t the lowest estimate they received, but there’s a reason for that. We stand behind our work, we guarantee our drainage systems, and we make sure the job is done right from start to finish. 💪

For this one we installed:
• Two 4-inch discharge lines
• Multiple catch basins
• A channel drain
• A new French drain system
• Removed and reset 3 areas of pavers
• Seeded and hayed the disturbed areas for a clean finished look

A lot went into this one, but now this property is set up much better for the next heavy rain. 🌧️

Drainage issues? Water going where it shouldn’t? Give GSL a call before the next storm rolls in.
