Project manager Steve went out to meet with Vinny , after seeing the Hugh puddle in the middle of the crawlspace plus and few wall cracks that were currently leaking we knew this crawlspace needed a full encapsulation system with drainage system and a Grate Sump . Vinny had useable space in the crawlspace that he wasn't currently using after installing our system he now has almost 500sq of useable space that he plan on using for storage. Problem solved !

The challenge we faced was that the wall that was leaking was built on a slab. To address this, we built a wall one block high and then installed below-grade waterproofing on the outside.

The challenge we faced was that this was a commercial building, so we could only work on the job on Saturdays and Sundays.

To address this, Project Manager Steve C. went out and met with the property owner, and the solution he provided was a drainage system on all outside walls along with a full vapor barrier, mold treatment to protect against wall leaks, and a Grate Sump in the low spot. After the job was finished, all the damp smells and odors went away, and now they have zero customer complaints.

Project Manager Steve C went out and gave the homeowners a few options to keep the basement dry all the time , he even recommended starting with the Grate-Sump , sump pump and the wet area of the basement . The homeowners have the option of adding the perimeter drainage system at a later date . After few rains and the homeowners hearing the new Sump pump keeping the ground water below the slap during storms their problem is solved .

The challenges we faced were the large amount of mud on the floor, bowing walls, a high water table, and the fact that there were no basement windows.

To address this, we first took care of the bowing walls with reinforced wall-stabilizing straps. Then, we handled the water problem with a full perimeter drainage system and two sump locations. We also added seven glass block windows and power-washed the floor down.

The challenge we faced was that it was a tight area to dig, so we had to hand dig everything.

To address this, our Project Manager Ed went out and knew exactly what it would take to get the issue resolved quickly. He proposed an egress escape window and well. The township approved everything, and both the new homeowners and previous clients are happy.

After a thorough inspection, our team determined that the issue was likely due to external water infiltration combined with inadequate interior drainage, threatening the integrity of the basement and the finishes within it. Challenges Identified • Water Intrusion: Water was seeping through the walls, particularly where the floor meets the foundation, likely due to poor exterior drainage and cracks in the foundation. • Finished Basement Damage: The basement was finished with drywall, carpeting, and trim, which were being compromised by the moisture, creating a risk of mold, mildew, and wood rot. • Mold Growth: The damp conditions had led to visible mold spots on the trim and along the edges of the floor, affecting both the aesthetic and air quality of the space. Solution: Comprehensive Waterproofing and Drainage System We worked closely with the homeowners to develop a targeted plan that would address both the water intrusion and the damage to their finished basement. The solution involved a multi-step approach: 1. Interior Drainage System Installation: • We installed a sub-floor drainage system #GrateDrain around the perimeter of the basement. This included a French drain system to capture water before it could reach the walls and floor. • The water is directed into a sump pit where it is pumped away from the foundation, keeping the basement dry and preventing further water damage. After the project was completed the homeowners were able to refinish their basement with peace of mind knowing it would be free of groundwater seepage thanks to Jamison ..

Project Manager Steve Custus went out to meet with the homeowners and the solutions they came up with was two foundation crack repairs where the blunt of the water was entering the basement. During the Basement inspection the homeowner pointed out a few areas where he also wanted the walls clean of potential mold growth. The installation crew arrived at 7:15am in Foremen Ken Mcknight in crew started the installation and during the install they found a Sump pit covered under the concrete slab that was filled with water . Since Ken is a senior Foremen he knew exactly what to do he recommended the homeowners add a fast Sump to the existing liner under the basement floor to remove the ground water seepage.
