What is concrete lifting?

It's the process of raising sunken concrete using polyurethane foam injection.

Driveways, sidewalks, patios, pool decks, garage floors, and interior slabs.

When can I use the concrete again?

Typically within 15–30 minutes after injection.

Is it cheaper than replacing concrete?

Yes — usually a fraction of the cost of full replacement.

How long does foam last?

It's a long-term solution that won't wash out or degrade like older methods.

Basement Waterproofing for Your Home.

Your basement should be a usable, dry part of your home — not a source of damp odors, ruined storage, or mold. If water is finding its way in, only a proper waterproofing system can stop it permanently. We diagnose first, then prescribe the right combination of interior OR exterior solutions for your specific situation.

Water issues in your basement show up in different ways — each pointing to a different cause. Here are the most common signs Long Island homeowners spot first. Click any sign to learn more.

Water in Your Basement

Pooling water, damp floors, or steady seepage after every storm. The cause varies by sign and so does the right repair.

Worker prepping a damp basement block wall

Wet Basement Walls

Damp patches, water streaks, or visible moisture on basement walls. Often more than just “humidity.”

Musty Basement Smell

That earthy, stale odor isn’t cosmetic. It’s mold spores and damp materials — and an air-quality issue.

Humidity in Basement

High relative humidity rots wood framing, wrecks stored items, and creates conditions for mold.

Basement Waterproofing Solutions

There’s no single “waterproofing” system because there’s no single cause. We use five complementary systems — alone or in combination — based on what we find in your inspection.

French Drains & Sump Pumps

Custom heavy-duty pipe, dimple mat, and pro-series pumps with battery backup. Longer service life than box-store units.

Interior Drainage Systems

Perimeter drain at the footing captures water at the cove joint where wall meets floor — the #1 leak point. Routes water silently.

Crew running skid steer for exterior excavation

Exterior Waterproofing

Excavation + modern membrane application stops water at the wall before it ever reaches the basement. Best long-term protection.

Crack Injection

High-pressure epoxy or polyurethane fills cracks from front to back. Permanent, flexes with movement, dries water-tight.

Crystalline Waterproofing

Penetrates concrete and forms permanent crystal structures inside it — sealing capillary water and stopping efflorescence at its source.

We get it right the first time, every time. Our solutions are built to last — backed by lifetime warranty.
