Water seeping in where the wall meets the floor? Call now and we'll connect you with an independent, licensed and insured interior waterproofing contractor in Del Rio who installs drain tile, a sump system and wall membranes without digging up your yard.

When a basement is built, the footing is poured first, then the walls, then the floor slab. The seam where the slab meets the wall, called the cove joint, is never truly sealed. It's a cold joint between two separate pours. When groundwater rises around the house, hydrostatic pressure pushes water up through that seam and through the gap between the footing and the slab.
That's the reason seepage so often starts as a dark line along the base of the wall. Sealing the joint from inside rarely works for long, because the pressure behind it doesn't go away. Instead of fighting the water, interior drainage collects it beside the footing and pumps it out before it reaches the floor.
For most existing homes in Del Rio, it's the most practical full solution. It's installed entirely from inside, works in any season and costs considerably less than excavating around the whole house.

Most failed interior systems failed because of how they were installed, not because the concept doesn't work. The first is a trench that doesn't go deep enough. The drain tile needs to sit beside the footing, not just under the edge of the slab, or water still finds its way up through the cove joint.
The second is the wrong stone. Drain tile should be bedded in washed, clean stone so water flows freely. Dirty gravel or reused soil clogs the pipe over time. Some systems also use a filter fabric sleeve on the pipe to keep fine silt out.
Third is pitch and layout. The drain tile has to slope toward the sump, and a long basement may need more than one sump or a cleanout port for future flushing. Ask the contractor how many access points the system has.
Finally, the pump has to match the water. An undersized pump runs constantly and burns out early. An oversized one short-cycles. A contractor who sizes the pump to your actual inflow and lift height, and adds a backup, is building a system meant to last.

Good interior drainage comes down to careful installation.
You're connected with insured, independent contractors, licensed where required, who handle the full install.
Written quotes are priced by the linear foot of drain tile, plus the sump package, membrane and any weep holes, with nothing hidden.
Local scheduling is usually quick, with prompt inspections and short lead times on installs.
Walk-behind slab saws with water or vacuum dust control, electric jackhammers, HEPA air scrubbers and plastic containment for clean work.
These parts work together as one drainage system.

Perforated pipe is set in clean stone in a trench beside the footing, then covered with fresh concrete, leaving a drainage gap at the wall.
All the drain tile feeds a lidded basin, where a properly sized submersible pump discharges the water outside.
Dimple membrane on the walls guides seepage down into the drain channel and keeps moisture off future framing.
Weep holes at the base of block walls let water trapped in the cores drain into the drain tile.
A second pump on battery power takes over during outages or if the primary pump fails. A high-water alarm warns you before water reaches the floor.
The discharge line exits through the rim joist and runs well away from the foundation. A freeze guard fitting lets water escape if the outside line ices over.
Interior drainage is usually priced by the linear foot of drain tile, so the size of the basement and how many walls need treatment set the baseline. A partial run along one wall can cost a fraction of a full perimeter. Foundation type matters next, since block walls need weep holes and poured walls don't. Obstacles add labor: finished walls that must be opened, stairs, built-in shelves, the furnace and water heater sitting close to the wall.
The sump package changes the price as well. A single pump in a new basin is the baseline, a battery backup and alarm add to it, and a basement with heavy inflow may need two pumps or two pits. Wall membranes, dehumidifiers and electrical work for a dedicated pump circuit are often separate lines. Ask the contractor to mark the drain tile route and sump location on a sketch so you can compare quotes on the same layout.
It's also worth asking what happens to the concrete and debris. Breaking out a perimeter strip produces a surprising amount of rubble, and hauling it away should be included in the quote. So should the final floor patch, dust containment and cleanup. If you plan to finish the basement later, mention it at the start, because the contractor may suggest a wall membrane or a slightly different drain layout that makes finishing easier and protects the new walls from day one.
A clear process, start to finish.

I was dreading the dust, but they set up plastic walls and an air scrubber. Upstairs stayed clean, and they hauled every bit of concrete away.

Weep holes, membrane and drain tile turned our damp block basement into a space we can finish.

Two-day job, clear quote, no surprises. The contractor showed me how to test the pump and the backup before he left.

It collects water beside the footing in perforated drain tile, before it reaches the floor, and channels it to a sump pump that discharges it outside. It relieves the pressure that forces water through the cove joint.
You'll see a new concrete strip along the edge. In finished basements it's usually hidden under flooring and baseboard. In unfinished spaces it's visible but clean.
Typically the lower section of finished walls has to come out. If you want to avoid that entirely, ask about exterior waterproofing.
It's noisy during cutting, but containment keeps dust out of the rest of the house. Most families stay home during the work.
Very little. Test the sump pump a couple of times a year, keep the discharge line clear and replace the backup battery as recommended. Some contractors offer annual service checks.
Yes, partial runs are common. The contractor will tell you whether a partial run will do the job or just push water to the next wall.
