Basement Waterproofing, Crawl Space & Foundation Repair in West Lafayette

Our expert crew addressed an active water intrusion issue caused by a pipe penetrating through the foundation wall. To properly resolve the problem, the exterior of the foundation was excavated at the point of penetration to fully expose the affected area. Once exposed, the pipe and surrounding foundation wall were professionally sealed on the exterior using industrial-grade epoxy to create a watertight barrier. The interior side of the wall penetration was also cleaned, prepared, and sealed with epoxy to provide an additional layer of protection. This comprehensive inside-and-out repair permanently stopped the leak, preventing further water intrusion and protecting the basement from future moisture damage.

The crew installed 86 feet of AmeriDrain crawlspace drainage system to capture and redirect groundwater away from the foundation. A new AmeriSump sump station was added to ensure reliable water removal and protection against moisture intrusion. To further improve moisture control, the team installed 500 square feet of 6-mil vapor barrier, providing a sealed ground covering to reduce humidity and protect the crawlspace environment.

The installation team completed the installation of one Brown Turtle crawlspace access door to provide a durable, secure, and weather-resistant entry point to the crawlspace. The access door was carefully fitted and sealed to help prevent the intrusion of moisture, pests, and outside air while improving the overall appearance and functionality of the crawlspace entrance. Constructed from high-quality materials designed for long-term performance, the Turtle access door offers improved durability compared to traditional crawlspace access covers and helps maintain the integrity of the crawlspace environment. This upgrade enhances accessibility while providing additional protection for the area beneath the home.

This project involved replacing 65 feet of damaged 2x4 sill plate to restore the integrity of the home’s floor system. To control moisture and improve overall crawlspace conditions, our team installed 900 square feet of 6-mil vapor barrier, providing a durable protective layer across the ground. In addition, we applied 900 square feet of Timbor spray treatment to safeguard all exposed wood surfaces against mold, mildew, and pests.

The installation team completed a comprehensive crawlspace waterproofing and structural repair project designed to improve moisture control and restore the integrity of the floor system. The work included the installation of 134 linear feet of AmeriDrain interior crawlspace drainage system along the foundation perimeter to intercept groundwater intrusion and relieve hydrostatic pressure at the footing level. The drainage system was routed to one SuperSump sump station, which was installed to efficiently collect and discharge water away from the home through a dedicated exterior discharge line. To create a clean and controlled crawlspace environment, 1,150 square feet of the CleanSpace encapsulation system was installed across the crawlspace floor and sealed along foundation surfaces and penetrations to form a continuous, durable vapor barrier. This system helps prevent ground moisture from entering the crawlspace, reduces humidity levels, and protects structural components from moisture-related deterioration. The project was completed with the installation of one steel crawlspace access door, providing a secure, durable, and weather-resistant entry point while helping maintain the integrity of the encapsulation system. In addition to the waterproofing improvements, structural repairs were performed to restore proper support beneath the home. The repairs included the replacement of 30 linear feet of sill plate and the installation of six sister joists to reinforce weakened floor framing, improve load distribution, and enhance the overall stability of the floor system. Together, these upgrades provide long-term moisture protection, improved structural performance, and a healthier crawlspace environment.

Americrawl performed comprehensive structural wood repairs to restore the integrity and stability of the floor system. The work included replacing 18 feet of damaged rim joist and plate, along with 12 feet of deteriorated sill plate to ensure a solid perimeter foundation connection. Additionally, six sister joists were installed to reinforce weakened floor joists, improving overall floor support and reducing deflection. The project also included 450 square feet of subfloor replacement, providing a stable and level surface for the flooring above.

To address these concerns, Americrawl installed the AmeriDrain® interior drainage system along the perimeter of the crawl space. This system diverts and channels groundwater to the newly installed AmeriSump® pump station, a reliable sump pump designed to quickly remove water and discharge it safely away from the home’s foundation. To help manage ground moisture and improve air quality, a 6-mil polyethylene vapor barrier was installed across the crawl space floor. The barrier was carefully laid with overlapping seams, sealed, and secured around piers to create a continuous protective layer..

This project consists of installing a comprehensive CleanSpace encapsulation system across 2,250 square feet of crawl-space area. Work includes cleaning and preparing the space, addressing any debris or surface irregularities, and installing the CleanSpace vapor barrier to create a fully sealed moisture-controlled environment. The encapsulation system will help protect the home from humidity, mold growth, and vapor intrusion while improving overall energy efficiency and long-term structural performance. Upon completion, the crawl space will be cleaner, drier, and significantly better protected against moisture-related issues.

To control water intrusion, our team installed the AmeriDrain® interior drainage system along the crawl space perimeter. This system directs groundwater to the sump pump and discharges away from the foundation, keeping the space dry even during the rainy season. A polyethylene vapor barrier was then installed across the crawl space floor to reduce ground moisture. The barrier was laid with overlapping seams, secured around piers, and anchored in place. Finally, the entire crawl space’s exposed wood surfaces were treated with Tim-bor®, a borate-based solution that helps prevent mold growth, wood decay, and damage from wood-destroying insects. This step provides long-term protection for critical structural components like floor joists, beams, and sill plates.

Our expert crew completed a comprehensive crawlspace waterproofing and encapsulation project designed to provide long-term moisture control and protect the home's foundation and structural components. The project included the installation of 155 linear feet of AmeriDrain to collect and redirect groundwater away from the foundation, helping prevent standing water and reduce the risk of ongoing moisture intrusion. The drainage system was connected to one SuperSump sump pump system to provide reliable removal of collected groundwater. To further protect the crawlspace from excess moisture, our crew installed 1,400 square feet of CleanSpace encapsulation system to create a durable moisture barrier and help prevent moisture vapor from migrating into the crawlspace. Additionally, one Sedona dehumidifier was installed to help regulate humidity levels and maintain a more controlled crawlspace environment. The project also included the installation of one steel crawlspace access door, providing a durable and secure entry point. To address moisture-related concerns and protect the structural wood components, our crew applied 14,000 square feet of Timbor Spray throughout the crawlspace to help address fungal growth and protect the wood from further deterioration.
