Collierville is a town where a historic square sits a few miles from brand-new subdivisions, and both are built on the same shrink-swell clay. The housing stock runs from older brick homes near the Town Square to 1990s and 2000s brick-veneer houses out toward Houston Levee Road and the Fairgrounds, and most of those newer homes are slab-on-grade with the garage slab sitting a step down.

When Collierville homeowners in 38017 call Memphis Waterproofing, it is usually because water is showing up where it should not: a damp lower wall, a wet slab edge behind the shrub bed, a window well that fills during a July downpour, or a hairline crack in the foundation that has started to weep. We are a dedicated basement and foundation waterproofing contractor, fully insured, and we serve Collierville and the surrounding Memphis area.

Waterproofing Us in Collierville (38017)

Collierville sits on the same loess and clay soils as the rest of the Memphis metro, and that matters for below-grade work. The clay pockets swell after a wet spring and shrink in a dry summer, which puts lateral movement on foundation walls and opens cracks at corners and along cold joints. In the newer subdivisions off Houston Levee and Wolf River Boulevard, lots are graded to move water away from the house, but the shrink-swell cycle still works on the foundation, and downspouts that dump too close to the slab edge keep the soil against the house saturated. In the older blocks near the Town Square, lots are tighter and the grade often slopes back toward the house, so exterior grading and downspout extensions become part of the repair, not an afterthought.

Our team has worked below grade across Collierville and the Memphis area long enough to know when a crack is a simple epoxy injection job and when the water behind the wall is hydrostatic pressure that needs an interior drain tile system and a sump basin. We also handle exterior basement waterproofing with dimple board and a footing drain when the problem is best solved from the outside, and we repair bowing block walls with carbon fiber straps or wall anchors when the clay has pushed a wall out of plumb.

How a Job Works in Collierville

Step 1: you call (901) 519-3853 and we schedule a free basement inspection. We walk the lower level and the exterior grade with you, look for efflorescence, check the window wells and the sump basin, and test the crack patterns. You get a written scope with pricing before any work starts.

Step 2: we do the work. In Collierville that often means coordinating with an HOA for exterior access or staging equipment on a tight lot near the Square, and pulling permits through the local building department when the job involves structural repair, egress window cutting, or a sump discharge connection. We keep the excavation protected and the work area contained.

Step 3: cleanup and final walkthrough. We haul off debris, restore the grade, and walk the job with you so you can see the drain tile, the sump pump, and the discharge line before we leave. We leave your property clean.

Pricing in Collierville depends on the job. Foundation crack repair with epoxy or polyurethane injection starts at $450. Interior drain tile runs from $50 per linear foot, and exterior basement waterproofing starts at $95 per linear foot. A sump pump installation or replacement starts at $1,200, and a battery backup sump pump starts at $900. Basement waterproofing packages start at $2,500, foundation waterproofing starts at $3,500, and bowing wall repair starts at $600. French drains start at $25 per linear foot, and vapor barrier installation starts at $3 per square foot. The key cost factors are the length of the wall or drain run, access to the foundation, how much of the wall is damaged, and whether the work is an emergency. Call (901) 519-3853 for a free estimate.

My house is near the Collierville Town Square and the yard slopes back toward the foundation. Is that causing the damp wall in my lower level?

Very likely, yes. Negative grade is common on older lots near the Square, and when the soil against the house stays wet, water finds the cold joint at the top of the foundation wall. We check the grade, the downspout locations, and the wall itself. Sometimes regrading and downspout extensions solve it, and sometimes the wall needs crack injection plus an interior perimeter drain to handle the water that still reaches the footing.

Water is coming into my lower level right now after a storm. What should I do and how fast can you get to Collierville?

Call (901) 519-3853 and tell us what you are seeing. If water is actively entering, move stored items off the floor and away from the wall, and do not stand in standing water near electrical outlets. We prioritize active leaks and sump pump failures in Collierville and the surrounding area, and we can talk you through shutting off a failed pump or a blocked discharge line while a crew is dispatched.

What does a typical foundation crack repair cost in Collierville, and what makes the price go up?

Most single crack injections start at $450. The price goes up when the crack is wide, when it is actively weeping and needs polyurethane rather than epoxy, when there are multiple cracks, or when the crack is a symptom of a bowing wall that needs carbon fiber straps or wall anchors. We give you the number before we start, and we tell you plainly if sealing the crack is all you need.

Do I need a permit for basement waterproofing or foundation repair in Collierville?

It depends on the scope. Structural foundation repair, egress window cutting, and work that alters drainage or the sanitary connection of a sump discharge commonly require a permit, and thresholds vary. We confirm the requirement with the local building department before work begins, and you can review the City of Collierville website at https://www.colliervilletn.gov for the current rules. We do not start permitted work until the permit is in hand.

My Collierville HOA wants approval before exterior work, and my neighbor says the drain tile will cross the property line. How do you handle that?

We handle both. For HOA approval, we provide a written scope and a site plan you can submit, and we schedule the work around the approval timeline. For property lines, we locate the line before we dig and keep the drain tile and discharge line on your side unless you have a recorded easement or written permission from the neighbor. If the discharge needs to cross the line, we tell you before we mobilize.

Are you insured for work at my Collierville property?

Yes. Memphis Waterproofing is fully insured, with general liability coverage and workers' compensation for our crew.

What should I check on my Collierville home before the spring rainy season?

Walk the perimeter and make sure the grade slopes away from the foundation, extend the downspouts at least a few feet past the wall, clear the window wells, and test the sump pump by pouring water into the basin and watching the float. Look for new efflorescence or a crack that has widened since last year. If you see any of that, call (901) 519-3853 and we will take a look before the next round of thunderstorms.
