Basement Waterproofing in Morton Grove, IL
Morton Grove homes built in the 1950s through 1970s often have concrete block foundations that leak as they age. A-Proseal fixes block wall water problems and keeps your basement dry.
Aging Block Foundations Are Morton Grove's Biggest Basement Problem
Most homes in Morton Grove were built during the post-war construction boom of the 1950s, 1960s, and 1970s. Builders used concrete block walls for the foundation instead of poured concrete. These block walls are made of hollow units stacked with mortar between them. After 50 or more years, those mortar joints wear down and the blocks themselves start to break apart. Homes near the Dempster Street corridor, the Harrer Park area, and neighborhoods along Lincoln Avenue all share this same problem.
Concrete blocks are porous by nature. Water from the soil slowly seeps through the face of each block and fills the hollow cores inside. Over time the water builds up inside the wall. It leaks out through mortar joints, through cracks at the base, and through the floor joint where the wall meets the slab. You might see damp streaks running down the wall, puddles along the edges of the floor, or a white chalky powder on the surface of the blocks.
A-Proseal has been waterproofing block foundation basements across Morton Grove since 2000. We understand how these older walls fail and what it takes to stop the water for good. Our team installs drain tile systems that relieve pressure at the base of block walls, sump pumps that remove collected water, and wall treatments that seal porous blocks from the inside. Every system is designed around the way block foundations behave.

Signs Your Morton Grove Block Foundation Is Letting Water In
How We Fix Block Foundation Water in Morton Grove Basements
We Come Out and Look
We inspect every block wall in your Morton Grove basement. We check for bowing, cracked mortar, water stains, and soft spots in the blocks. We also test where water is entering and how much pressure the soil is putting on the walls. This evaluation is always free and takes about an hour.
We Make a Plan
Block walls hold water inside their hollow cores. We design a drainage plan that pulls water out of the cores and channels it to the sump pump. Every home gets a custom layout based on the wall condition, the number of courses, and where the worst leaking happens. You get a clear written estimate before we start.
We Get to Work
Our crew opens the base of the block wall to drain trapped water from the cores. We install drain tile below the floor, connect it to a sump pump, and seal the wall surface to stop moisture from passing through. If walls are bowing, we add reinforcement to stabilize them. Most Morton Grove projects finish in one to three days.
We Test Everything
We run water through the full system to make sure everything drains the way it should. Then we walk you through how the system works and hand over your warranty paperwork. Your Morton Grove basement stays dry from that point forward.
What You Get With Morton Grove Block Foundation Waterproofing
Block Core Drainage System
We open the base of block walls and connect the hollow cores to drain tile below the floor. This pulls trapped water out of the wall before it can leak into your basement.
High-Capacity Sump Pump
Block walls release a lot of water at once during heavy rain. Our pumps are built to handle that volume. Battery backup keeps everything running during storms and power outages.
Mortar Joint Sealing
We seal cracked and worn mortar joints between blocks so water cannot pass through them. This is one of the most common leak points in Morton Grove's older block foundations.
Block Wall Membrane
A waterproof membrane goes on the inside face of your block walls. This stops moisture from passing through the porous concrete and cuts basement humidity down to healthy levels.
Transferable Warranty
Our written warranty covers the work for the life of your home. If you sell your Morton Grove home, the warranty transfers to the new owner. That adds real value at closing time.
Quick, Clean Work
Most Morton Grove block foundation jobs take one to three days. Our crew protects your floors, controls dust, and cleans up completely. You get your basement back fast with no mess left behind.

Block Foundation Questions Morton Grove Homeowners Ask
Why do so many Morton Grove homes have block foundations?
Morton Grove grew fast after World War II. Builders in the 1950s through 1970s used concrete block walls because they were cheaper and faster to build than poured concrete. Block foundations were common across the Chicago suburbs during that era. The downside is that block walls are weaker and more porous than poured walls. After 50 or more years, the blocks and mortar joints break down and let water in.
How does water get inside a concrete block wall?
Concrete blocks are not solid. Each block has two or three hollow spaces called cores. Water from the soil pushes through the face of the block and through cracked mortar joints. It fills up inside the cores like a hidden reservoir. Eventually the water overflows out the bottom, leaking onto your basement floor at the joint where the wall meets the slab. You might not see water on the wall itself, but you will see it at the base.
What is the white powder on my block walls?
That white powder is called efflorescence. It happens when water passes through the concrete block and dissolves minerals inside the material. As the water reaches the surface and dries, it leaves the minerals behind as a white chalky film. Efflorescence itself is not harmful, but it is a clear sign that water is moving through your block walls. The blocks need to be sealed and the water source needs to be addressed.
Can bowing block walls be fixed without replacing them?
Yes, in most cases. If block walls are bowing inward from soil pressure, we can stabilize them with reinforcement systems like carbon fiber straps or steel beams. These hold the wall in place and prevent further movement. We also relieve the water pressure behind the wall with drain tile, which removes the force that caused the bowing in the first place. Full wall replacement is usually only needed in very severe cases.
Will painting or coating the blocks stop the leaking?
Surface coatings and waterproofing paint do not work well on block walls. The water pressure behind the blocks is too strong. Paint will bubble, peel, and flake off within a few months. The real solution is to drain the water from inside the cores and relieve the pressure at the base of the wall. That is what our block core drainage system does. It captures water before it has a chance to leak into your living space.
How soon can A-Proseal inspect my Morton Grove home?
We can usually visit your Morton Grove home the same day you call. Our crews work in the area regularly, including near the Morton Grove Metra station, Dempster Street, and neighborhoods along the North Shore Channel. The inspection is completely free. We look at your block walls, explain what we find, and give you a written estimate before we leave. There is no pressure to commit on the spot.
