Stop Basement Leaks With Interior Waterproofing in Las Vegas

Wet basements in Las Vegas often can't be fixed from outside. When digging up the yard is not an option, interior waterproofing routes groundwater to a sump pit before it crosses the slab. Las Vegas Concrete cuts the perimeter, installs drainage tile, sets the pump, and seals the wall so your basement stays dry. Free written estimate on every project.

The right tool for the job

When Interior Drainage Solves a Wet Basement

A wet basement in Las Vegas can come from groundwater seeping through the wall, cracks in the slab, or water pooling against the foundation during spring runoff. Exterior waterproofing is the gold standard when you can reach the outside of the wall, but many homes have finished landscapes, decks, or tight setbacks that make excavation impractical or too costly.

Interior waterproofing takes a different approach. Instead of stopping water before it reaches the wall, it accepts that water will arrive and intercepts it at the slab perimeter. A trench is cut along the inside of the wall, drainage tile is laid on stone, and the tile slopes to a sump pit where a pump moves the water out to daylight. The wall is sealed so groundwater drops into the tile instead of bleeding across the slab.

The result is a dry basement floor ready for renovation work, finished flooring, or storage. The slab stays dry, the wall dries inward, and the pump is the only moving part you maintain.

The installation sequence

How We Install Interior Basement Drainage

  1. Assess water entry and sump location

    We identify where water reaches the slab, measure the existing floor depth, and locate the best spot for the sump pit and discharge line before any cutting begins.

  2. Cut and excavate the perimeter

    The basement floor is cut along the wall perimeter, a trench is dug to the correct depth, and any failed or old drainage is removed so the new tile sits on clean stone.

  3. Lay tile and set the sump pit

    Drainage tile is placed in the trench on a stone bed, sloped toward a new sump pit at the low point. The pump and discharge line are installed and tested with water to confirm flow.

  4. Backfill, pour, and seal the wall

    Stone backfill is placed over the tile, the slab is poured to lock the system into the floor, and the wall face is sealed so groundwater enters the tile instead of the basement.

Interior vs. exterior

Interior Waterproofing Is Not a Foundation Repair

Interior waterproofing manages water that reaches the slab. It does not repair a cracked or failing wall, and it is not a substitute for exterior foundation waterproofing when the outside can be reached. If the wall itself is structurally compromised or if there is a known exterior cause that can be fixed from outside, that is the right path.

Interior waterproofing excels in established Las Vegas homes where the yard is finished, the basement is already built out, and the goal is to stop the floor from getting wet. The system is proven, the pump is reliable, and the basement stays dry through every spring melt and monsoon season.

Common questions

Interior Basement Waterproofing Questions, Answered

Drainage tile, sump pits, pumps and when interior is the right answer to a wet basement.

For its job, yes. The two systems do different work. Exterior keeps water from ever reaching the wall; interior accepts that water reaches the wall, intercepts it at the slab perimeter and pumps it out. When excavating outside is impractical, the interior system is the right one.
An interior system needs a sump pit and a pump to move collected water out. A battery backup pump is strongly recommended in Las Vegas, where spring runoff and power outages can overlap. We size the pump and pit to the inflow we measure.
The perimeter has to be opened up, which means baseboards, lower drywall and any finished flooring against the wall come off in the work zone. We coordinate that carefully so the rest of the basement is undisturbed.
It will intercept the water at the slab so the floor stays dry, but a leaking wall crack itself is a separate fix; pair this with crack repair or, if the crack is structural, foundation crack repair from the engineered side.
A typical residential interior system takes about a week from cut to closed slab, depending on the perimeter length and how much of the basement has to be uncovered to reach the work. The full schedule is in the quote.

We could not dig up the front of the house. Interior system put in, sump pit cut, dry basement two springs running. Honest about the system being the right tool here.

Existing finished basement, leaks in three corners. They opened only what they had to, installed the tile and sump, closed it back up clean. The pump runs, basement is dry.

They explained why interior was the answer in our situation and not just upselling exterior. The system has worked through every melt since. Trust earned.

Battery backup pump was their recommendation and we are glad we listened. Lost power for a day this spring; basement stayed dry the whole time. Worth every dollar.
