Our Waterproofing Process
We follow a comprehensive 6-step process to ensure your home is protected from water damage for years to come.
Site Assessment
Excavation
Foundation Repair
Waterproof Membrane
Drainage System
Backfilling

Site Assessment & Diagnosis
We begin with a full exterior inspection, identifying vulnerabilities such as foundation cracks, poor grading, or failing gutters. Every home is different — our team customizes the solution to your property's specific challenges.

Excavation
We carefully excavate the soil surrounding the home's foundation to access the underlying wall surface. This step is essential to properly apply waterproof membranes and drainage systems.

Foundation Repair
If any cracks, gaps, or structural issues are present in the foundation wall, we perform full repairs using hydraulic cement or polyurethane injection to stabilize and seal the structure.

Waterproof Membrane Application
A commercial-grade waterproof membrane or coating is applied to the exterior foundation walls. This serves as a barrier, preventing water from penetrating concrete or masonry surfaces.

Drainage System Installation
We install or upgrade perimeter drain systems (including French drains and footing drains) to redirect groundwater away from your foundation. Proper drainage is critical to long-term waterproofing success.

Backfilling & Landscaping
Once the waterproofing system is in place, we carefully backfill the excavation and restore your landscaping to its original condition or better.

They were transparent, explained all the details, answered my questions and most of all instilled trust. I had them do some waterproofing and install a French Drain in my basement. Beyond that, they did great work and quickly too. Tim was onsite the entire time and made sure the crew did everything at a high quality. And towards the end, they went above and beyond to make sure the space was in better shape than when they started. Much appreciated and I will definitely be bring them in for future work.

Very kind,pleasant and thorough. I've been under contract w/them since '21 and was just as pleased w/ their work now as I was when I was first introduced. I would recommend John and his team to anyone in need of chimney inspection/cleaning. Safe,reliable service! 👍👍 Ariel Sagiz2025-08-06Trustindex verifies that the original source of the review is Google. The owner John and his team of professionals completed a chimney cleaning and a stainless steel liner replacement. Very efficient, fast and most importantly got the job done right. Will use them again. Ahmet Can2025-07-29Trustindex verifies that the original source of the review is Google. Tim and his crew came out to fix some issues that we experienced due to settling of the pavers over time. They were courteous and took their time to do the repair in the right way. I asked Tim about the tattoo on his arm that had the A1 Everlast logo and he mentioned he has been with the company for 20 years. This kind of employee loyalty means that the company must be doing something right in terms of how it treats its employees. My philosophy is always happy employees mean happy customers and Tim delivered. I asked for a quote for some additional work in the yard as well based on today's experience. When a company lives up to its promises, I will trust them with repeat business.
