Exterior and Interior Solutions

We offer both exterior and interior basement waterproofing solutions to address a wide range of water intrusion issues. Our interior waterproofing solutions are designed to address any water leaks or seepage from the inside of your basement. This includes techniques such as installing interior drainage systems, applying sealants and coatings, and repairing any cracks or holes in the foundation walls. These methods are not only efficient but also minimally invasive, ensuring that your property is not disrupted during the waterproofing process.

For exterior waterproofing, we use advanced techniques to protect your basement from water intrusion from the outside. This includes installing exterior drainage systems, applying waterproof membranes, and using specialized materials to prevent water from penetrating through the foundation walls. Our team will assess your specific situation and recommend the best approach to keep your basement dry and well-protected.

Types of Drainage Solutions

Western Construction Systems offers a variety of drainage solutions to effectively manage water runoff and prevent water intrusion on your property. Whether you have a residential or commercial property, we have the right solution for you. Our range of drainage systems includes:

  • Below Slab De-watering Systems: Designed to remove excess water from beneath the concrete slab foundation, preventing moisture buildup and potential structural damage.

  • Exterior French Drains: These drains are installed around the perimeter of your property to collect surface water and divert it away from your home or building, preventing water from seeping into basements or crawl spaces.

  • Storm Drains: Storm drains are installed to collect rainwater from paved surfaces such as driveways, patios, and parking lots, directing it away from your property and preventing flooding.

  • Sump Pumps: Sump pumps are installed in basements or crawl spaces to pump out excess water and prevent flooding during heavy rainfall or rising groundwater levels.

What our customers are saying


Amazing experience with this company!

"I contacted several foundation repair companies and I'm so happy that I found Tyler and WCS. The company replied to my questions quickly, the team that came over was professional and courteous, the repair on my foundation fixing the level was top notch work. I highly recommend this company!"

- Zeth O


Western Construction Systems came out and did exceptional work at my house!

"They went above and beyond my expectations! They were friendly, professional, and hard-working! They took care of all the issues that I had concerns with and then some! Their prices were fair, especially for the high quality of work that they did! I know I pestered them with questions, but they were patient every single time. Before I contacted them to have the work done, I had high anxiety about the drainage issues. When they were finished, I felt confident that there were no more issues. Peace of mind is priceless!"

- Robyn S


Tyler, Juan and their crew did an amazing job at our home.

"They installed their gutter system and were finished in just a few days knowing that we didn't have our hot water heater connected. They are great with communicating and assessing a situation to figure out what needs to be done. Highly recommended!"
