Foundation Crack Repair & Sealing in Cranston
Even minor cracks in foundation walls can allow significant water intrusion. Our services include crack repair using epoxy or polyurethane injection to seal these entry points for good. This method fills the entire depth of the crack, restoring strength and preventing water penetration. We address both vertical and horizontal cracks, knowing that horizontal cracks can signal structural issues that need a thorough assessment before sealing. Addressing these early prevents further water damage and costly future repairs.

Shower Wall Waterproofing in Cranston
Tile and grout are not waterproof on their own, so water reaches the backer board in every shower. If the walls were built without a proper membrane, moisture soaks into studs and drywall. We remove failing tile, install cement board or foam board and apply a membrane such as Schluter Kerdi, RedGard or Hydro Ban. Seams, corners and niches get extra attention before new tile is set.
Laundry Room and Utility Wall Waterproofing in Cranston, RI
Washing machine hoses, utility sinks and water heaters can all leak into nearby walls. We replace burst-prone rubber hoses with braided stainless hoses and install leak pans and shutoff valves. Walls around water heaters and laundry boxes can be sealed to resist water damage. These small upgrades prevent costly drywall repairs.
Foundation Crack Repair in Cranston
Even small cracks in your foundation walls can allow water to seep into your basement or crawl space. Our walls waterproofing service includes foundation crack repair using specialized epoxy or polyurethane injection techniques. These materials fill and seal cracks, preventing future water entry and often strengthening the foundation. Addressing cracks promptly in Cranston homes is crucial to avoid larger, more costly structural issues.
Plumbing Leak Behind Walls in Cranston
A slow drip from a shower valve, supply stub or drain fitting can soak a wall for months before you notice. We find the leak with moisture meters, thermal imaging and pressure tests. The damaged section of pipe or valve is replaced, and wet drywall is cut out and dried. Once the cavity is dry, we restore the wall and seal any wet-area walls.
Sump Pump Installation and Repair in Cranston, RI
Sump pumps are a critical part of many interior waterproofing systems, particularly in homes that see heavy rainfall. We install high-capacity sump pumps designed to handle large volumes of water, keeping your basement dry even during heavy storms. Our services include primary sump pump installation, battery backup sump pump systems for power outages, and routine maintenance or repair of existing units. We make sure the discharge line is routed properly so water does not circulate back toward the foundation.
Exterior Foundation Waterproofing in Cranston
Exterior foundation waterproofing involves excavating around the foundation to apply a waterproof membrane or coating directly to the wall. This is often the most effective method for preventing water from entering the basement or crawl space. We use high-quality asphalt-modified polyurethane membranes or polymer-based coatings that resist hydrostatic pressure and soil movement. Rocky glacial soil and ledge are common in Rhode Island, which can make digging for sewer and water lines slower and more involved. Proper drainage solutions, such as French drains, are also integrated to divert water away.

Drainage System Integration in Cranston, RI
Effective walls waterproofing often requires a solid drainage system to divert water away from your foundation. This can include interior perimeter drains that channel water to a sump pump, or exterior French drains that collect surface water. Our team designs and installs custom drainage solutions for Cranston, RI properties, so water is efficiently managed and moved away from your home's vulnerable areas.

Frequently Asked Questions About Walls Waterproofing in Cranston
Shower wall waterproofing with a membrane system usually runs $1,200 to $3,500 including demolition and backer board, not counting new tile. Exterior block wall sealing often costs $800 to $3,000 depending on size. Below-grade foundation waterproofing generally ranges from $2,500 to $8,000.
Walls waterproofing is generally not recommended as a DIY project due to its complexity and the high importance of a sound foundation. It often involves heavy excavation, specialized equipment, precise material application, and knowledge of drainage principles and local building codes. Improper waterproofing can lead to more severe and costly damage down the line, so professional help is the smart choice.
Waterproofing prevents the moisture mold needs to grow. Existing mold should be removed and the area dried before sealing. We remove affected materials when needed and recommend remediation for larger growth.
Yes. Sealing a wall with an active leak behind it traps water and causes more damage. We always fix the leak and dry the cavity first.
Skilled DIYers can roll on liquid membranes, but mistakes at seams, corners and drains often lead to leaks. Shower pans also require correct slope and flood testing. Professional installation reduces the risk of hidden water damage.
We use a range of high-performance waterproofing membranes and coatings depending on the application and foundation type. These can include liquid asphalt-modified polyurethane, rubberized asphalt membranes, bentonite clay systems, and crystalline coatings.
